20348007,How can I find out the total physical memory (RAM) of my Linux box suitable to be parsed by a shell script?,"I'm creating a shell script to find out the total physical memory in some RHEL Linux boxes. First of all I want to stress that I'm interested in the total physical memory recognized by the kernel, not just the available memory . Therefore, please, avoid answers suggesting to read /proc/meminfo or to use the free , top or sar commands -- In all these cases, their "" total memory "" values mean "" available memory "" ones. The first thought was to read the boot kernel messages: Memory: 61861540k/63438844k available (2577k kernel code, 1042516k reserved, 1305k data, 212k init) But in some Linux boxes, due to the use of EMC2's PowerPath software and its flooding boot messages in the kernel startup, that useful boot kernel message is not available, not even in the /var/log/dmesg file. The second option was the dmidecode command (I'm warned against the possible mismatch of kernel recognized RAM and real RAM due to the limitations of some older kernels and architectures). The option --memory simplifies the script but I realized that older releases of that command have no --memory option. My last chance was the getconf command. It reports the memory page size, but not the total number of physical pages -- the _PHYS_PAGES system variable seems to be the available physical pages, not the total physical pages. # getconf -a | grep PAGES PAGESIZE 4096 _AVPHYS_PAGES 1049978 _PHYS_PAGES 15466409 My question: Is there another way to get the total amount of physical memory, suitable to be parsed by a shell script?","How can I find out the total physical memory (RAM) of my Linux box suitable to be parsed by a shell script?

Therefore, please, avoid answers suggesting to read /proc/meminfo or to use the free , top or sar commands -- In all these cases, their "" total memory "" values mean "" available memory "" ones. The first thought was to read the boot kernel messages: Memory: 61861540k/63438844k available (2577k kernel code, 1042516k reserved, 1305k data, 212k init) But in some Linux boxes, due to the use of EMC2's PowerPath software and its flooding boot messages in the kernel startup, that useful boot kernel message is not available, not even in the /var/log/dmesg file. The second option was the dmidecode command (I'm warned against the possible mismatch of kernel recognized RAM and real RAM due to the limitations of some older kernels and architectures). The option --memory simplifies the script but I realized that older releases of that command have no --memory option. My last chance was the getconf command. It reports the memory page size, but not the total number of physical pages -- the _PHYS_PAGES system variable seems to be the available physical pages, not the total physical pages. # getconf -a | grep PAGES PAGESIZE 4096 _AVPHYS_PAGES 1049978 _PHYS_PAGES 15466409 My question: Is there another way to get the total amount of physical memory, suitable to be parsed by a shell script?","linux, ram, memory-size",147,349220,15,https://stackoverflow.com/questions/20348007/how-can-i-find-out-the-total-physical-memory-ram-of-my-linux-box-suitable-to-b
394984,Best practice to run Linux service as a different user,"Services default to starting as root at boot time on my RHEL box. If I recall correctly, the same is true for other Linux distros which use the init scripts in /etc/init.d . What do you think is the best way to instead have the processes run as a (static) user of my choosing? The only method I'd arrived at was to use something like: su my_user -c 'daemon my_cmd &>/dev/null &' But this seems a bit untidy... Is there some bit of magic tucked away that provides an easy mechanism to automatically start services as other, non-root users? EDIT: I should have said that the processes I'm starting in this instance are either Python scripts or Java programs. I'd rather not write a native wrapper around them, so unfortunately I'm unable to call setuid() as Black suggests.","Best practice to run Linux service as a different user Services default to starting as root at boot time on my RHEL box.

47202468,Segfault on declaring a variable of type vector&lt;shared_ptr&lt;int&gt;&gt;,"Code Here is the program that gives the segfault. #include <iostream> #include <vector> #include <memory> int main() { std::cout << ""Hello World"" << std::endl; std::vector<std::shared_ptr<int>> y {}; std::cout << ""Hello World"" << std::endl; } Of course, there is absolutely nothing wrong in the program itself. The root cause of the segfault depends on the environment in which its built and ran. Background We, at Amazon, use a build system which builds and deploys the binaries ( lib and bin ) in an almost machine independent way. For our case, that basically means it deploys the executable (built from the above program) into $project_dir/build/bin/ and almost all its dependencies (i.e the shared libraries) into $project_dir/build/lib/ . Why I used the phrase ""almost"" is because for shared libraries such libc.so , libm.so , ld-linux-x86-64.so.2 and possibly few others, the executable picks from the system (i.e from /lib64 ). Note that it is supposed to pick libstdc++ from $project_dir/build/lib though. Now I run it as follows: $ LD_LIBRARY_PATH=$project_dir/build/lib ./build/bin/run segmentation fault However if I run it, without setting the LD_LIBRARY_PATH . It runs fine.

Questions I know that its very difficult to debug like this and probably I've not given a lot of informations about the environments and all. But still, my question is: what could be the possible root-cause for this segfault? How to debug further and find that? Once I find the issue, fix would be easy. Compiler and Platform I'm using GCC 4.9 on RHEL5. Experiments E#1 If I comment the following line: std::vector<std::shared_ptr<int>> y {}; It compiles and runs fine! E#2 I just included the following header to my program: #include <boost/filesystem.hpp> and linked accordingly. Now it works without any segfault. So it seems by having a dependency on libboost_system.so.1.53.0. , some requirements are met, or the problem is circumvented! E#3 Since I saw it working when I made the executable to be linked against libboost_system.so.1.53.0 , so I did the following things step by step. Instead of using #include <boost/filesystem.hpp> in the code itself, I use the original code and ran it by preloading libboost_system.so using LD_PRELOAD as follows: $ LD_PRELOAD=$project_dir/build/lib/libboost_system.so $project_dir/build/bin/run and it ran successfully! Next I did ldd on the libboost_system.so which gave a list of libs, two of which were: /lib64/librt.so.1 /lib64/libpthread.so.0 So instead of preloading libboost_system , I preload librt and libpthread separately: $ LD_PRELOAD=/lib64/librt.so.1 $project_dir/build/bin/run $ LD_PRELOAD=/lib64/libpthread.so.0 $project_dir/build/bin/run In both cases, it ran successfully. Now my conclusion is that by loading either librt or libpthread (or both ), some requirements are met or the problem is circumvented! I still dont know the root cause of the issue, though. Compilation and Linking Options Since the build system is complex and there are lots of options which are there by default. So I tried to explicitly add -lpthread using CMake's set command, then it worked, as we have already seen that by preloading libpthread it works! In order to see the build difference between these two cases ( when-it-works and when-it-gives-segfault ), I built it in verbose mode by passing -v to GCC, to see the compilation stages and the options it actually passes to cc1plus (compiler) and collect2 (linker).

55457902,Keycloak Customization to run custom java in authentication flow,"Please let me know if this is not the right place to post, but I have been looking all over for information regarding this and can't seem to find a concise answer. I have been attempting to use keycloak to meet our application's user management requirements. While I have found keycloak to be very capable and quite effective, I have run into what may be a dead end for our usage. Background: Traditionally, our application has used a very basic login framework that would verify the authentication. Then using a third party application, that we cannot change , identify the roles that user would have via a wsdl operation and insert into our applications database. For example, if we verify the user John Doe exists and authenticate his credentials, we call the wsdl in our java code to get what roles that user should have (super user, guest, regular user). Obviously this entire framework is pretty flawed and at the end of the day, this is why weve chosen to use keycloak. Problem Unfortunately, as I mentioned we cannot change the third party application, and we must get user role mappings from this wsdl operation. I know there is a way to create/modify keycloak's users and roles via java functions. However, in order to keep this architecture modular is there a way to configure the authentication flow to reach out to this WSDL on keycloaks side for role mapping ? (i.e. not in the application code but maybe in a scriplet in the authentication flow) What I am looking for is essentially how to configure the authentication flow to run something as simple as ""hello world"" in java after the credentials are verified but before access is granted.

33817481,Large PCIe DMA Linux x86-64,"I am working with a high speed serial card for high rate data transfers from an external source to a Linux box with a PCIe card. The PCIe card came with some 3rd party drivers that use dma_alloc_coherent to allocate the dma buffers to receive the data. Due to Linux limitations however, this approach limits data transfers to 4MB. I have been reading and trying multiple methods for allocating a large DMA buffer and haven't been able to get one to work. This system has 32GB of memory and is running Red Hat with a kernel version of 3.10 and I would like to make 4GB of that available for a contiguous DMA. I know the preferred method is scatter/gather, but this is not possible in my situation as there is a hardware chip that translated the serial protocol into a DMA beyond my control, where the only thing that I can control is adding an offset to the incoming addresses (ie, address zero as seen from the external system can be mapped to address 0x700000000 on the local bus). Since this is a one-off lab machine I think the fastest/easiest approach would be to use mem=28GB boot configuration parameter. I have this working fine, but the next step to access that memory from virtual space is where I am having problems. Here is my code condensed to the relevant components: In the kernel module: size_t len = 0x100000000ULL; // 4GB size_t phys = 0x700000000ULL; // 28GB size_t virt = ioremap_nocache( phys, len ); // address not usable via direct reference size_t bus = (size_t)virt_to_bus( (void*)virt ); // this should be the same as phys for x86-64, shouldn't it? // OLD WAY /*size_t len = 0x400000; // 4MB size_t bus; size_t virt = dma_alloc_coherent( devHandle, len, &bus, GFP_ATOMIC ); size_t phys = (size_t)virt_to_phys( (void*)virt );*/ In the application: // Attempt to make a usable virtual pointer u32 pSize = sysconf(_SC_PAGESIZE); void* mapAddr = mmap(0, len+(phys%pSize), PROT_READ|PROT_WRITE, MAP_SHARED, devHandle, phys-(phys%pSize)); virt = (size_t)mapAddr + (phys%pSize); // do DMA to 0x700000000 bus address printf(""Value %x\n"", *((u32*)virt)); // this is returning zero Another interesting thing is that before doing all of this, the physical address returned from dma_alloc_coherent is greater than the amount of RAM on the system(0x83d000000). I thought that in x86 the RAM will always be the lowest addresses and therefore I would expect an address less than 32GB.

Here is my code condensed to the relevant components: In the kernel module: size_t len = 0x100000000ULL; // 4GB size_t phys = 0x700000000ULL; // 28GB size_t virt = ioremap_nocache( phys, len ); // address not usable via direct reference size_t bus = (size_t)virt_to_bus( (void*)virt ); // this should be the same as phys for x86-64, shouldn't it? // OLD WAY /*size_t len = 0x400000; // 4MB size_t bus; size_t virt = dma_alloc_coherent( devHandle, len, &bus, GFP_ATOMIC ); size_t phys = (size_t)virt_to_phys( (void*)virt );*/ In the application: // Attempt to make a usable virtual pointer u32 pSize = sysconf(_SC_PAGESIZE); void* mapAddr = mmap(0, len+(phys%pSize), PROT_READ|PROT_WRITE, MAP_SHARED, devHandle, phys-(phys%pSize)); virt = (size_t)mapAddr + (phys%pSize); // do DMA to 0x700000000 bus address printf(""Value %x\n"", *((u32*)virt)); // this is returning zero Another interesting thing is that before doing all of this, the physical address returned from dma_alloc_coherent is greater than the amount of RAM on the system(0x83d000000). I thought that in x86 the RAM will always be the lowest addresses and therefore I would expect an address less than 32GB. Any help would be appreciated.","c++, linux, redhat, dma, pci-e",10,2645,1,https://stackoverflow.com/questions/33817481/large-pcie-dma-linux-x86-64

116640,Low Java single process thread limit in Red Hat Linux,"I'm experiencing an issue on a test machine running Red Hat Linux (kernel version is 2.4.21-37.ELsmp) using Java 1.6 (1.6.0_02 or 1.6.0_04). The problem is, once a certain number of threads are created in a single thread group, the operating system is unwilling or unable to create any more. This seems to be specific to Java creating threads, as the C thread-limit program was able to create about 1.5k threads. Additionally, this doesn't happen with a Java 1.4 JVM... it can create over 1.4k threads, though they are obviously being handled differently with respect to the OS. In this case, the number of threads it's cutting off at is a mere 29 threads. This is testable with a simple Java program that just creates threads until it gets an error and then prints the number of threads it created. The error is a java.lang.OutOfMemoryError: unable to create new native thread This seems to be unaffected by things such as the number of threads in use by other processes or users or the total amount of memory the system is using at the time. JVM settings like Xms, Xmx, and Xss don't seem to change anything either (which is expected, considering the issue seems to be with native OS thread creation). The output of ""ulimit -a"" is as follows: core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) 4 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) 10240 cpu time (seconds, -t) unlimited max user processes (-u) 7168 virtual memory (kbytes, -v) unlimited The user process limit does not seem to be the issue. Searching for information on what could be wrong has not turned up much, but this post seems to indicate that at least some Red Hat kernels limit a process to 300 MB of memory allocated for stack, and at 10 MB per thread for stack, it seems like the issue could be there (though it seems strange and unlikely as well). I've tried changing the stack size with ""ulimit -s"" to test this, but any value other than 10240 and the JVM does not start with an error of: Error occurred during initialization of VM Cannot create VM thread. Out of system resources. I can generally get around Linux, but I really don't know much about system configuration, and I haven't been able to find anything specifically addressing this kind of situation.

The issue also did not occur using a 1.4 JVM (does occur with 1.6.0_02 and 1.6.0_04 JVMs, can't test with a 1.5 JVM at the moment). The code for the thread test I'm using is as follows: public class ThreadTest { public static void main(String[] pArgs) throws Exception { try { // keep spawning new threads forever while (true) { new TestThread().start(); } } // when out of memory error is reached, print out the number of // successful threads spawned and exit catch ( OutOfMemoryError e ) { System.out.println(TestThread.CREATE_COUNT); System.exit(-1); } } static class TestThread extends Thread { private static int CREATE_COUNT = 0; public TestThread() { CREATE_COUNT++; } // make the thread wait for eternity after being spawned public void run() { try { sleep(Integer.MAX_VALUE); } // even if there is an interruption, dont do anything catch (InterruptedException e) { } } } } If you run this with a 1.4 JVM it will hang when it can't create any more threads and require a kill -9 (at least it did for me).

21217441,Red Hat linux - &quot;turn off&quot; encryption checking,"I have a Red Hat 6.5 Linux implementation that uses LUKS to encrypt the system and - for reasons that aren't relevant - I would like to ""turn off"" boot encryption checking for a period of time. It will be turned on again at some point so even if it is possible to remove the LUKS encryption entirely, that is not a solution I am interested in. What I want is to auto-provide the LUKS password on boot so that it doesn't need to be entered manually - thus logically ""turning off"" encryption even though still actually enabled. Now, while this is straightforward for secondary devices ie. by creating a key file, applying the key file to the encrypted devices and amending /etc/crypttab to reference the key file, one still has to enter at least one password on boot - because, if the primary device is LUKS encrypted, then it first has to be decrypted before /etc/crypttab is accessible. There is a way I have seen of removing the requirement to enter the initial password which is: create a key file apply the key file to the encrypted device ie. enabling the key for the device to be decrypted Copy the key file to a removable not-encrypted device (eg. a flash drive) append rd.luks.key= absolute path to key file : removable not-encrypted device to the booting kernel line in /boot/grub/grub.conf On boot, make sure the removable not-encrypted device is inserted and can be referenced by the boot process. This all looks good, except that I don't want a removable not-encrypted device involved. I simply want the server to boot as though it wasn't encrypted. The only way I can see to achieve this is to replace removable not-encrypted device with normal not-encrypted device . In which case the boot process would read normal not-encrypted device , get the key and use it to decrypt the encrypted devices ...hey presto encryption is disabled. The only device I can find on my system that fulfills the normal not-encrypted device criteria is /dev/sda1 ie. /boot , so I performed the above steps with step 3 and 4 as follows: as above as above copy key file to /boot/keyfile.key append rd.luks.key=/boot/keyfile.key:/dev/sda1 n/a Unfortunately I can't seem to get this to work. Red Hat boots and I don't get asked for a password (as expected), however towards the end of the boot process, it fails with ""Kernel panic - not syncing: Attempted to kill init! ...""

The only way I can see to achieve this is to replace removable not-encrypted device with normal not-encrypted device . In which case the boot process would read normal not-encrypted device , get the key and use it to decrypt the encrypted devices ...hey presto encryption is disabled. The only device I can find on my system that fulfills the normal not-encrypted device criteria is /dev/sda1 ie. /boot , so I performed the above steps with step 3 and 4 as follows: as above as above copy key file to /boot/keyfile.key append rd.luks.key=/boot/keyfile.key:/dev/sda1 n/a Unfortunately I can't seem to get this to work. Red Hat boots and I don't get asked for a password (as expected), however towards the end of the boot process, it fails with ""Kernel panic - not syncing: Attempted to kill init! ..."" This behaviour is identical whichever of the following I use: rd.luks.key=/boot/keyfile.key:/dev/sda1 rd.luks.key=/keyfile.key:/dev/sda1 rd.luks.key=/keyfile.key rd.luks.key=/ someKeyFileThatIknowDoesNotExist.key :/dev/sda1 So my questions are as follows: Is what I am trying to do possible If yes, then... where should I be putting the key file what is the rd.luks.key value I should use to reference the key file thanks in advance for any help","linux, encryption, redhat",7,5418,2,https://stackoverflow.com/questions/21217441/red-hat-linux-turn-off-encryption-checking

Apparently my locale is set to en_US: [xxx@xxx ~]$ locale LANG=en_US.UTF-8 LC_CTYPE=""en_US.UTF-8"" LC_NUMERIC=""en_US.UTF-8"" LC_TIME=""en_US.UTF-8"" LC_COLLATE=""en_US.UTF-8"" LC_MONETARY=""en_US.UTF-8"" LC_MESSAGES=""en_US.UTF-8"" LC_PAPER=""en_US.UTF-8"" LC_NAME=""en_US.UTF-8"" LC_ADDRESS=""en_US.UTF-8"" LC_TELEPHONE=""en_US.UTF-8"" LC_MEASUREMENT=""en_US.UTF-8"" LC_IDENTIFICATION=""en_US.UTF-8"" LC_ALL= I've looked into what i presume is a proper config file for this particular locale: /usr/share/i18n/locales/en_US and looked for anything that might be related to ""dot"", ""decimal separator"" etc. Found LC_MONETARY and LC_NUMERIC, however mon_decimal_point for monetary and decimal_point for numeric were already set to - which I'm quite sure is a ""dot"". Just for giggles I also changed mon_thousands_sep and thousands_sep to and restarted. No help here.

I have a virtual machine set up, so I can mess it up as much as i want prior to changing things on my work laptop.","linux, locale, redhat",5,5684,2,https://stackoverflow.com/questions/39365386/numeric-keyboard-dot-instead-of-comma

I have some code (actually part of an installation tool) that needs to retrieve the user name, home directory and other details. It is using the getpwuid() call to do this based on the user id. A simplified breakdown: uid_t uid = getuid(); printf(""UID = %d\n"", uid); errno = 0; struct passwd* udetails = getpwuid(uid); if (udetails != NULL) { printf(""User name = %s\n"", udetails->pw_name); } else { printf(""getpwuid returns NULL, errno=%d\n"", errno); } This works without problems where the user is a local user (in that system's /etc/passwd). When the user is an LDAP-authenticated user, the call the getuid returns the user ID or the current user, but the call to getpwuid returns 0, with no error code set in errno. According to the documentation, this means that the user doesn't exist. Should this work? According to the getpwuid manpage: The getpwnam() function returns a pointer to a structure containing the broken-out fields of the record in the password database (e.g., the local password file /etc/passwd, NIS, and LDAP) that matches the username name. The getpwuid() function returns a pointer to a structure containing the broken-out fields of the record in the password database that matches the user ID uid. Is an alternative call required to get the details if the current user was authenticated by LDAP? Is it necessary to open the LDAP database in an application, or should the system call handle that?

28258135,Manually patching for Ghost vulnerability on legacy server,"I have a legacy Redhat ES 3.x server (that I cannot put a later distro on due to limitations in an ancient, unsupported application) and I am trying to manually patch glibc on it for the Ghost vulnerability.

8998743,RHEL + PHP : writing files outside /var/www/html?,"I'm trying to open a file for read/write. I've been developing on Ubuntu, and have had no problems whatsoever. Now it's time to deploy to the RHEL server, and I discover there seems to be some kind of restriction on the location of a file to be written.

57811879,Deploy keycloak custom spi deployment,"I try to create a custom spi, in my keycloak project, following the basic keycloack structure, I add custom provider interface which extends provider, custom provider factory and implement custom spi for them as keycloak documentation says, and they do in their source code, after that i create a custom implementation for my provider and provider factory, i create the file in META-INF/services as documentation says, and I am using ear aproach to deploy like in beercloak example, but when I try to use my provider in code null pointer exception is thrown, this only happens when I try to add a custom spi, if I am implementing aprovider which has an existing keycloak spi it works, it also works if I am using the modules aproach, where i create a new module with jboss-cli, but that aproach seems hard to maintain, anyone has any ideas why this happens and how can I solve it or what is the best approach, thanks. 08:43:48,264 WARN

9985030,How does the garbage collector work in PHP,"I have a PHP script that has a large array of people, it grabs their details from an external resource via SOAP, modifies the data and sends it back. Due to the size of the details I upped PHP's memory to 128MB. After about 4 hours of running (It will probably take 4 days to run) it ran out of memory. Heres the basics of what it does: $people = getPeople(); foreach ($people as $person) { $data = get_personal_data(); if ($data == ""blah"") { importToPerson(""blah"", $person); } else { importToPerson(""else"", $person); } } After it ran out of memory and crashed I decided to initialise $data before the foreach loop and according to top , memory usage for the process hasn't risen above 7.8% and it's been running for 12 hours. So my question is, does PHP not run a garbage collector on variables initialised inside the loop even if reused? Is the system reclaiming the memory and PHP hasn't marked it as usable yet and will eventually crash again (I've upped it to 256MB now so I've changed 2 things and not sure which has fixed it, I could probably change my script back to answer this but don't want to wait another 12 hours for it to crash to figure out)? I'm not using the Zend framework so the other question like this I don't think is relevant. EDIT: I don't actually have an issue with the script or what it's doing. At the moment, as far as all system reporting is concerned I don't have any issues.

66827542,Strategy to keep Tomcat updated?,"I maintain a number of RedHat Enterprise Linux (both 7 and 8) servers (>100) with different applications. To keep my sanity, I'm of course using tools such as Ansible, and more to the point of this questions, locally mirrored copies of public RPM repositories (using Satellite Server for the purpose). Updates are applied regularly from these repositories to keep the servers secure. A few of these servers need Apache Tomcat installed. This is one of the few applications that is, to my knowledge, not available from any RPM-based repository; it must be installed manually from a tarball. Updates are also manual (aided by an Ansible role, but I still have to be aware of the new version and manually change it). Are there any strategies to keep Tomcat up-to-date with little or no constant attention? Update: I found half of a solution to my problem. By default, Tomcat keeps the installation and the instance configuration mixed together in a single directory tree identified by CATALINA_HOME. That makes updating Tomcat without clobbering your configuration complicated. To solve that, you can put the instance-specific files in a separate directory tree identified with the CATALINA_BASE variable. Upgrading Tomcat then becomes as easy as: Download the new tarball. Untar it to a new location Review the readme and changelog for any breaking changes. Update the CATALINA_HOME variable to point to the new location, while keeping the CATALINA_BASE variable unchanged. Restart Tomcat, using the scripts in the new CATALINA_HOME bin directory. I am not providing code here because where and how you set CATALINA_HOME and CATALINA_BASE will vary. I set both variables in the service unit file that also starts Tomcat. Still open: finding a way to automatically find out when a new release of Tomcat is published.","Strategy to keep Tomcat updated?

11005396,how to write a bash shell script to ssh to remote machine and change user and export a env variable and do other commands,"I have a webservice that runs on multiple different remote redhat machines. Whenever I want to update the service I will sync down the new webservice source code written in perl from a version control depot(I use perforce) and restart the service using that new synced down perl code. I think it is too boring to log to remote machines one by one and do that series of commands to restart the service one by one manully. So I wrote a bash script update.sh like below in order to ""do it one time one place, update all machines"". I will run this shell script in my local machine. But it seems that it won't work. It only execute the first command ""sudo -u webservice_username -i"" as I can tell from the command line in my local machine. (The code below only shows how it will update one of the remote webservice. The ""export P4USER=myname"" is for usage of perforce client) #!/bin/sh ssh myname@remotehost1 'sudo -u webservice_username -i ; export P4USER=myname; cd dir ; p4 sync ; cd bin ; ./prog --domain=config_file restart ; tail -f ../logs/service.log' Why I know the only first command is executed? Well because after I input the password for the ssh on my local machine, it shows: Your environment has been modified. Please check /tmp/webservice.env. And it just gets stuck there. I mean no return. As suggested by a commentor, I added ""-t"" for ssh #!/bin/sh ssh -t myname@remotehost1 'sudo -u webservice_username -i ; export P4USER=myname; cd dir ; p4 sync ; cd bin ; ./prog --domain=config_file restart ; tail -f ../logs/service.log' This would let the local commandline return. But it seems weird, it cannot cd to that ""dir"", it says ""cd:dir: No such file or directory"" it also says ""p4: command not found"". So it looks like the sudo -u command executes with no effect and the export command has either not executed or excuted with no effect. A detailed local log file is like below: Your environment has been modified. Please check /tmp/dir/.env. bash: line 0: cd: dir: No such file or directory bash: p4: command not found bash: line 0: cd: bin: No such file or directory bash: ./prog: No such file or directory tail: cannot open `../logs/service.log' for reading: No such file or directory tail: no files remaining","how to write a bash shell script to ssh to remote machine and change user and export a env variable and do other commands I have a webservice that runs on multiple different remote redhat machines.

The ""export P4USER=myname"" is for usage of perforce client) #!/bin/sh ssh myname@remotehost1 'sudo -u webservice_username -i ; export P4USER=myname; cd dir ; p4 sync ; cd bin ; ./prog --domain=config_file restart ; tail -f ../logs/service.log' Why I know the only first command is executed? Well because after I input the password for the ssh on my local machine, it shows: Your environment has been modified. Please check /tmp/webservice.env. And it just gets stuck there. I mean no return. As suggested by a commentor, I added ""-t"" for ssh #!/bin/sh ssh -t myname@remotehost1 'sudo -u webservice_username -i ; export P4USER=myname; cd dir ; p4 sync ; cd bin ; ./prog --domain=config_file restart ; tail -f ../logs/service.log' This would let the local commandline return. But it seems weird, it cannot cd to that ""dir"", it says ""cd:dir: No such file or directory"" it also says ""p4: command not found"". So it looks like the sudo -u command executes with no effect and the export command has either not executed or excuted with no effect. A detailed local log file is like below: Your environment has been modified. Please check /tmp/dir/.env. bash: line 0: cd: dir: No such file or directory bash: p4: command not found bash: line 0: cd: bin: No such file or directory bash: ./prog: No such file or directory tail: cannot open `../logs/service.log' for reading: No such file or directory tail: no files remaining","linux, bash, ssh, perforce, redhat",4,18504,3,https://stackoverflow.com/questions/11005396/how-to-write-a-bash-shell-script-to-ssh-to-remote-machine-and-change-user-and-ex

But a number of searches did not yield a result. I need to be able to remove an existing user from an existing group with a command line script. It appears that the usermod easily allows me to add a user to a supplementary group with this command: usermod -a -G supgroup1,supgroup2 username Without the ""-a"" option, if the user is currently a member of a group which is not listed, the user will be removed from the group. Does anyone have a perl (or Python) script that allows the specification of a user and group for removal? Am I missing an obvious existing command, or well-known solution forthis? Thanks in advance! Thanks to J.J. for the pointer to the Unix::Group module, which is part of Unix-ConfigFile. It looks like the command deluser would do what I want, but was not in any of my existing repositories.

21877092,Five second wait in activemq cms MessageProducer.send with zookeeper,"I'm testing ActiveMQ 5.9.0 with Replicated LevelDB . Running against a standalone ActiveMQ with a local LevelDB store, each producer.send(message) call takes about 1 ms. With my replicated setup with 3 zookeepers and 3 activemq brokers, producer.send(message) takes slightly more than 5 seconds to return! This happens even with sync=""local_mem"" in <replicatedLevelDB ... > . It's always just above 5 seconds, so there seems to be some strange wait/timeout involved. Does this ring a bell? It doesn't matter if I set brokerurl to failover:(<all three brokers>) or just tcp://brokerX , where brokerX is in the replicated LevelDB setup. There is no noticable delay sending messages in the brokerX web ui (hawtio).

2995987,"migrating Solaris to RH: network latency issue, tcp window size &amp; other tcp parameters","I have a client/server app (Java) that I'm migrating from Solaris to RH Linux. since I started running it in RH, I noticed some issues related to latency. I managed to isolate the problem that looks like this: client sends 5 messages (32 bytes each) in a row (same application timestamp) to the server. server echos messages. client receives replies and prints round trip time for each msg. in Solaris, all is well: I get ALL 5 replies at the same time, roughly 80ms after having sent original messages (client & server are several thousands miles away from each other: my ping RTT is 80ms, all normal). in RH, first 3 messages are echoed normally (they arrive 80ms after they've been sent), however the following 2 arrive 80ms later (so total 160ms RTT). the pattern is always the same. clearly looked like a TCP problem. on my solaris box, I had previously configured the tcp stack with 2 specific options: disable nagle algorithm globally set tcp_deferred_acks_max to 0 on RH, it's not possible to disable nagle globally, but I disabled it on all of my apps' sockets (TCP_NODELAY). so I started playing with tcpdump (on the server machine), and compared both outputs: SOLARIS : 22 2.085645 client server TCP 56150 > 6006 [PSH, ACK] Seq=111 Ack=106 Win=66672 Len=22 ""MSG_1 RCV"" 23 2.085680 server client TCP 6006 > 56150 [ACK] Seq=106 Ack=133 Win=50400 Len=0 24 2.085908 client server TCP 56150 > 6006 [PSH, ACK] Seq=133 Ack=106 Win=66672 Len=22 ""MSG_2 RCV"" 25 2.085925 server client TCP 6006 > 56150 [ACK] Seq=106 Ack=155 Win=50400 Len=0 26 2.086175 client server TCP 56150 > 6006 [PSH, ACK] Seq=155 Ack=106 Win=66672 Len=22 ""MSG_3 RCV"" 27 2.086192 server client TCP 6006 > 56150 [ACK] Seq=106 Ack=177 Win=50400 Len=0 28 2.086243 server client TCP 6006 > 56150 [PSH, ACK] Seq=106 Ack=177 Win=50400 Len=21 ""MSG_1 ECHO"" 29 2.086440 client server TCP 56150 > 6006 [PSH, ACK] Seq=177 Ack=106 Win=66672 Len=22 ""MSG_4 RCV"" 30 2.086454 server client TCP 6006 > 56150 [ACK] Seq=127 Ack=199 Win=50400 Len=0 31 2.086659 server client TCP 6006 > 56150 [PSH, ACK] Seq=127 Ack=199 Win=50400 Len=21 ""MSG_2 ECHO"" 32 2.086708 client server TCP 56150 > 6006 [PSH, ACK] Seq=199 Ack=106 Win=66672 Len=22 ""MSG_5 RCV"" 33 2.086721 server client TCP 6006 > 56150 [ACK] Seq=148 Ack=221 Win=50400 Len=0 34 2.086947 server client TCP 6006 > 56150 [PSH, ACK] Seq=148 Ack=221 Win=50400 Len=21 ""MSG_3 ECHO"" 35 2.087196 server client TCP 6006 > 56150 [PSH, ACK] Seq=169 Ack=221 Win=50400 Len=21 ""MSG_4 ECHO"" 36 2.087500 server client TCP 6006 > 56150 [PSH, ACK] Seq=190 Ack=221 Win=50400 Len=21 ""MSG_5 ECHO"" 37 2.165390 client server TCP 56150 > 6006 [ACK] Seq=221 Ack=148 Win=66632 Len=0 38 2.166314 client server TCP 56150 > 6006 [ACK] Seq=221 Ack=190 Win=66588 Len=0 39 2.364135 client server TCP 56150 > 6006 [ACK] Seq=221 Ack=211 Win=66568 Len=0 REDHAT : 17 2.081163 client server TCP 55879 > 6006 [PSH, ACK] Seq=111 Ack=106 Win=66672 Len=22 ""MSG_1 RCV"" 18 2.081178 server client TCP 6006 > 55879 [ACK] Seq=106 Ack=133 Win=5888 Len=0 19 2.081297 server client TCP 6006 > 55879 [PSH, ACK] Seq=106 Ack=133 Win=5888 Len=21 ""MSG_1 ECHO"" 20 2.081711 client server TCP 55879 > 6006 [PSH, ACK] Seq=133 Ack=106 Win=66672 Len=22 ""MSG_2 RCV"" 21 2.081761 client server TCP 55879 > 6006 [PSH, ACK] Seq=155 Ack=106 Win=66672 Len=22 ""MSG_3 RCV"" 22 2.081846 server client TCP 6006 > 55879 [PSH, ACK] Seq=127 Ack=177 Win=5888 Len=21 ""MSG_2 ECHO"" 23 2.081995 server client TCP 6006 > 55879 [PSH, ACK] Seq=148 Ack=177 Win=5888 Len=21 ""MSG_3 ECHO"" 24 2.082011 client server TCP 55879 > 6006 [PSH, ACK] Seq=177 Ack=106 Win=66672 Len=22 ""MSG_4 RCV"" 25 2.082362 client server TCP 55879 > 6006 [PSH, ACK] Seq=199 Ack=106 Win=66672 Len=22 ""MSG_5 RCV"" 26 2.082377 server client TCP 6006 > 55879 [ACK] Seq=169 Ack=221 Win=5888 Len=0 27 2.171003 client server TCP 55879 > 6006 [ACK] Seq=221 Ack=148 Win=66632 Len=0 28 2.171019 server client TCP 6006 > 55879 [PSH, ACK] Seq=169 Ack=221 Win=5888 Len=42 ""MSG_4 ECHO + MSG_5 ECHO"" 29 2.257498 client server TCP 55879 > 6006 [ACK] Seq=221 Ack=211 Win=66568 Len=0 so, I got confirmation things are not working correctly for RH: packet 28 is sent TOO LATE, it looks like the server is waiting for packet 27's ACK before doing anything. seems to me it's the most likely reason... then I realized that the ""Win"" parameters are different on Solaris & RH dumps: 50400 on Solaris, only 5888 on RH. that's another hint... I read the doc about the slide window & buffer window, and played around with the rcvBuffer & sendBuffer in java on my sockets, but never managed to change this 5888 value to anything else (I checked each time directly with tcpdump). does anybody know how to do this ? I'm having a hard time getting definitive information, as in some cases there's ""auto-negotiation"" that I might need to bypass, etc... I eventually managed to get only partially rid of my initial problem by setting the ""tcp_slow_start_after_idle"" parameter to 0 on RH, but it did not change the ""win"" parameter at all. the same problem was there for the first 4 groups of 5 messages, with TCP retransmission & TCP Dup ACK in tcpdump, then the problem disappeared altogether for all following groups of 5 messages.

I managed to isolate the problem that looks like this: client sends 5 messages (32 bytes each) in a row (same application timestamp) to the server. server echos messages. client receives replies and prints round trip time for each msg. in Solaris, all is well: I get ALL 5 replies at the same time, roughly 80ms after having sent original messages (client & server are several thousands miles away from each other: my ping RTT is 80ms, all normal). in RH, first 3 messages are echoed normally (they arrive 80ms after they've been sent), however the following 2 arrive 80ms later (so total 160ms RTT). the pattern is always the same. clearly looked like a TCP problem. on my solaris box, I had previously configured the tcp stack with 2 specific options: disable nagle algorithm globally set tcp_deferred_acks_max to 0 on RH, it's not possible to disable nagle globally, but I disabled it on all of my apps' sockets (TCP_NODELAY). so I started playing with tcpdump (on the server machine), and compared both outputs: SOLARIS : 22 2.085645 client server TCP 56150 > 6006 [PSH, ACK] Seq=111 Ack=106 Win=66672 Len=22 ""MSG_1 RCV"" 23 2.085680 server client TCP 6006 > 56150 [ACK] Seq=106 Ack=133 Win=50400 Len=0 24 2.085908 client server TCP 56150 > 6006 [PSH, ACK] Seq=133 Ack=106 Win=66672 Len=22 ""MSG_2 RCV"" 25 2.085925 server client TCP 6006 > 56150 [ACK] Seq=106 Ack=155 Win=50400 Len=0 26 2.086175 client server TCP 56150 > 6006 [PSH, ACK] Seq=155 Ack=106 Win=66672 Len=22 ""MSG_3 RCV"" 27 2.086192 server client TCP 6006 > 56150 [ACK] Seq=106 Ack=177 Win=50400 Len=0 28 2.086243 server client TCP 6006 > 56150 [PSH, ACK] Seq=106 Ack=177 Win=50400 Len=21 ""MSG_1 ECHO"" 29 2.086440 client server TCP 56150 > 6006 [PSH, ACK] Seq=177 Ack=106 Win=66672 Len=22 ""MSG_4 RCV"" 30 2.086454 server client TCP 6006 > 56150 [ACK] Seq=127 Ack=199 Win=50400 Len=0 31 2.086659 server client TCP 6006 > 56150 [PSH, ACK] Seq=127 Ack=199 Win=50400 Len=21 ""MSG_2 ECHO"" 32 2.086708 client server TCP 56150 > 6006 [PSH, ACK] Seq=199 Ack=106 Win=66672 Len=22 ""MSG_5 RCV"" 33 2.086721 server client TCP 6006 > 56150 [ACK] Seq=148 Ack=221 Win=50400 Len=0 34 2.086947 server client TCP 6006 > 56150 [PSH, ACK] Seq=148 Ack=221 Win=50400 Len=21 ""MSG_3 ECHO"" 35 2.087196 server client TCP 6006 > 56150 [PSH, ACK] Seq=169 Ack=221 Win=50400 Len=21 ""MSG_4 ECHO"" 36 2.087500 server client TCP 6006 > 56150 [PSH, ACK] Seq=190 Ack=221 Win=50400 Len=21 ""MSG_5 ECHO"" 37 2.165390 client server TCP 56150 > 6006 [ACK] Seq=221 Ack=148 Win=66632 Len=0 38 2.166314 client server TCP 56150 > 6006 [ACK] Seq=221 Ack=190 Win=66588 Len=0 39 2.364135 client server TCP 56150 > 6006 [ACK] Seq=221 Ack=211 Win=66568 Len=0 REDHAT : 17 2.081163 client server TCP 55879 > 6006 [PSH, ACK] Seq=111 Ack=106 Win=66672 Len=22 ""MSG_1 RCV"" 18 2.081178 server client TCP 6006 > 55879 [ACK] Seq=106 Ack=133 Win=5888 Len=0 19 2.081297 server client TCP 6006 > 55879 [PSH, ACK] Seq=106 Ack=133 Win=5888 Len=21 ""MSG_1 ECHO"" 20 2.081711 client server TCP 55879 > 6006 [PSH, ACK] Seq=133 Ack=106 Win=66672 Len=22 ""MSG_2 RCV"" 21 2.081761 client server TCP 55879 > 6006 [PSH, ACK] Seq=155 Ack=106 Win=66672 Len=22 ""MSG_3 RCV"" 22 2.081846 server client TCP 6006 > 55879 [PSH, ACK] Seq=127 Ack=177 Win=5888 Len=21 ""MSG_2 ECHO"" 23 2.081995 server client TCP 6006 > 55879 [PSH, ACK] Seq=148 Ack=177 Win=5888 Len=21 ""MSG_3 ECHO"" 24 2.082011 client server TCP 55879 > 6006 [PSH, ACK] Seq=177 Ack=106 Win=66672 Len=22 ""MSG_4 RCV"" 25 2.082362 client server TCP 55879 > 6006 [PSH, ACK] Seq=199 Ack=106 Win=66672 Len=22 ""MSG_5 RCV"" 26 2.082377 server client TCP 6006 > 55879 [ACK] Seq=169 Ack=221 Win=5888 Len=0 27 2.171003 client server TCP 55879 > 6006 [ACK] Seq=221 Ack=148 Win=66632 Len=0 28 2.171019 server client TCP 6006 > 55879 [PSH, ACK] Seq=169 Ack=221 Win=5888 Len=42 ""MSG_4 ECHO + MSG_5 ECHO"" 29 2.257498 client server TCP 55879 > 6006 [ACK] Seq=221 Ack=211 Win=66568 Len=0 so, I got confirmation things are not working correctly for RH: packet 28 is sent TOO LATE, it looks like the server is waiting for packet 27's ACK before doing anything. seems to me it's the most likely reason... then I realized that the ""Win"" parameters are different on Solaris & RH dumps: 50400 on Solaris, only 5888 on RH. that's another hint... I read the doc about the slide window & buffer window, and played around with the rcvBuffer & sendBuffer in java on my sockets, but never managed to change this 5888 value to anything else (I checked each time directly with tcpdump). does anybody know how to do this ? I'm having a hard time getting definitive information, as in some cases there's ""auto-negotiation"" that I might need to bypass, etc... I eventually managed to get only partially rid of my initial problem by setting the ""tcp_slow_start_after_idle"" parameter to 0 on RH, but it did not change the ""win"" parameter at all. the same problem was there for the first 4 groups of 5 messages, with TCP retransmission & TCP Dup ACK in tcpdump, then the problem disappeared altogether for all following groups of 5 messages.

54227180,OpenLDAP does not validate TLS certificate,"I am trying to run OpenLDAP (2.4.44 on RedHat 7.6) as a client against an existing LDAP server with TLS. This is working well - too well, actually. It looks to me as if OpenLDAP accepts any server certificate, instead of validating it against the CAs I provided. Here is my ldap.conf file: TLS_CACERT /etc/openldap/cacerts/ldap-2019.pem TLS_REQCERT demand URI ldaps://ldap.mydomain.com/ BASE ou=people,dc=mydomain,dc=com # Some optimizations suggested by # [URL] set_cachesize 0 268435456 1 set_lg_regionmax 262144 set_lg_bsize 2097152 What I want to accomplish is of course that OpenLDAP validates the certificate for ldaps://ldap.mydomain.com against the list of CAs in TLS_CACERT. But in reality, no matter what I put into the TLS_CACERT file, openldap seems to connect successfully, just as long as it is a valid PEM file. What am I missing? Is there a second list of CAs that OpenLDAP consults? I also removed the CAs in /etc/pki/tls, just in case. More details: ldapsearch -x -uid=somename fails if I delete the file I specified in TLS_CACERT. It also fails if TLS_CACERT is not a valid PEM file. This is of course expected behavior when the client cannot validate a TLS certificate: ldapsearch -x uid=somename ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) But if I put a completely nonsensical certificate into the TLS_CACERT file, ldapsearch will return a result as if the server's certificate was valid. ldapsearch -x uid=somename # extended LDIF # # LDAPv3 # base <ou=people,dc=mydomain,dc=com> (default) with scope subtree # filter: uid=somename # requesting: ALL # # somename, People, mydomain.com dn: uid=somename,ou=People,dc=mydomain,dc=com ... For example, I tried using a certificate for www.google.com as a TLS_CACERT. I would have expected this connection to fail with the same ""Can't contact LDAP server"" error. Update: I found the cause but not the solution. OpenLDAP uses the certificate bundle in /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem . Renaming this file causes ldapsearch to behave as I expected, but of course that is not an acceptable solution since this is a systemwide file, not just for OpenLDAP. So my new question is: how do I prevent OpenLDAP from using this file? Update 2: For clarification, this is on RedHat 7.6, and OpenLDAP 2.4.44. I assume that using the systemwide CA bundle is a RedHat modification to the stock OpenLDAP.","OpenLDAP does not validate TLS certificate I am trying to run OpenLDAP (2.4.44 on RedHat 7.6) as a client against an existing LDAP server with TLS.

Is there a second list of CAs that OpenLDAP consults? I also removed the CAs in /etc/pki/tls, just in case. More details: ldapsearch -x -uid=somename fails if I delete the file I specified in TLS_CACERT. It also fails if TLS_CACERT is not a valid PEM file. This is of course expected behavior when the client cannot validate a TLS certificate: ldapsearch -x uid=somename ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) But if I put a completely nonsensical certificate into the TLS_CACERT file, ldapsearch will return a result as if the server's certificate was valid. ldapsearch -x uid=somename # extended LDIF # # LDAPv3 # base <ou=people,dc=mydomain,dc=com> (default) with scope subtree # filter: uid=somename # requesting: ALL # # somename, People, mydomain.com dn: uid=somename,ou=People,dc=mydomain,dc=com ... For example, I tried using a certificate for www.google.com as a TLS_CACERT. I would have expected this connection to fail with the same ""Can't contact LDAP server"" error. Update: I found the cause but not the solution. OpenLDAP uses the certificate bundle in /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem . Renaming this file causes ldapsearch to behave as I expected, but of course that is not an acceptable solution since this is a systemwide file, not just for OpenLDAP. So my new question is: how do I prevent OpenLDAP from using this file? Update 2: For clarification, this is on RedHat 7.6, and OpenLDAP 2.4.44. I assume that using the systemwide CA bundle is a RedHat modification to the stock OpenLDAP.","ssl, redhat, openldap",3,2629,0,https://stackoverflow.com/questions/54227180/openldap-does-not-validate-tls-certificate

When i run redis server with below command $ ./redis-server --protected-mode no and then when i restart my redis-server all data which store in redis is deleted. but when i run normal redis server command to start then its working fine. $ ./redis-server I have check redis config file its has appendonly yes but i don't know why its not persistent its data with protect mode. Is there any way to use protected-mode and save data on disk with redis. I am using redis 4.0.1 version you can check in screenshot first screenshot i run with without protected mode. when i close request its says data saving to disk but when i run with protected mode check what hapeen Its not saving data on disk. I have attach some part of config file which i have changed. I have already using appendonly yes , don't know what i am doing wrong. ################################ SNAPSHOTTING ################################ # # Save the DB on disk: # # save <seconds> <changes> # # Will save the DB if both the given number of seconds and the given # number of write operations against the DB occurred. # # In the example below the behaviour will be to save: # after 900 sec (15 min) if at least 1 key changed # after 300 sec (5 min) if at least 10 keys changed # after 60 sec if at least 10000 keys changed # # Note: you can disable saving completely by commenting out all ""save"" lines. # # It is also possible to remove all the previously configured save # points by adding a save directive with a single empty string argument # like in the following example: # # save """" save 900 1 save 300 10 save 60 10000 save 1 1 # By default Redis will stop accepting writes if RDB snapshots are enabled # (at least one save point) and the latest background save failed. # This will make the user aware (in a hard way) that data is not persisting # on disk properly, otherwise chances are that no one will notice and some # disaster will happen. # # If the background saving process will start working again Redis will # automatically allow writes again. # # However if you have setup your proper monitoring of the Redis server # and persistence, you may want to disable this feature so that Redis will # continue to work as usual even if there are problems with disk, # permissions, and so forth. stop-writes-on-bgsave-error yes # Compress string objects using LZF when dump .rdb databases? # For default that's set to 'yes' as it's almost always a win. # If you want to save some CPU in the saving child set it to 'no' but # the dataset will likely be bigger if you have compressible values or keys. rdbcompression yes # Since version 5 of RDB a CRC64 checksum is placed at the end of the file. # This makes the format more resistant to corruption but there is a performance # hit to pay (around 10%) when saving and loading RDB files, so you can disable it # for maximum performances. # # RDB files created with checksum disabled have a checksum of zero that will # tell the loading code to skip the check. rdbchecksum yes # The filename where to dump the DB dbfilename dump.rdb # The working directory. # # The DB will be written inside this directory, with the filename specified # above using the 'dbfilename' configuration directive. # # The Append Only File will also be created inside this directory. # # Note that you must specify a directory here, not a file name. dir ./ ############################## APPEND ONLY MODE ############################### # By default Redis asynchronously dumps the dataset on disk. This mode is # good enough in many applications, but an issue with the Redis process or # a power outage may result into a few minutes of writes lost (depending on # the configured save points). # # The Append Only File is an alternative persistence mode that provides # much better durability. For instance using the default data fsync policy # (see later in the config file) Redis can lose just one second of writes in a # dramatic event like a server power outage, or a single write if something # wrong with the Redis process itself happens, but the operating system is # still running correctly. # # AOF and RDB persistence can be enabled at the same time without problems. # If the AOF is enabled on startup Redis will load the AOF, that is the file # with the better durability guarantees. # # Please check [URL] for more information. appendonly yes # The name of the append only file (default: ""appendonly.aof"") appendfilename ""appendonly.aof"" # The fsync() call tells the Operating System to actually write data on disk # instead of waiting for more data in the output buffer. Some OS will really flush # data on disk, some other OS will just try to do it ASAP. # # Redis supports three different modes: # # no: don't fsync, just let the OS flush the data when it wants. Faster. # always: fsync after every write to the append only log. Slow, Safest. # everysec: fsync only one time every second. Compromise. # # The default is ""everysec"", as that's usually the right compromise between # speed and data safety. It's up to you to understand if you can relax this to # ""no"" that will let the operating system flush the output buffer when # it wants, for better performances (but if you can live with the idea of # some data loss consider the default persistence mode that's snapshotting), # or on the contrary, use ""always"" that's very slow but a bit safer than # everysec. # # More details please check the following article: # [URL] # # If unsure, use ""everysec"". # appendfsync always appendfsync everysec # appendfsync no # When the AOF fsync policy is set to always or everysec, and a background # saving process (a background save or AOF log background rewriting) is # performing a lot of I/O against the disk, in some Linux configurations # Redis may block too long on the fsync() call.

76998416,Sending logs of (rootless) podman containers to ELK?,"I am struggling with the $question for a while and it is time to ask for some guidance. We have 10+ containers that runs on different RHEL VMs deployed via ansible as systemd service (in other words, there is no cubernetes or other container orchestration service on top of /next to podman installed) These containers are running as rootless containers. Unfortunately the docker (podman) socket is not active on the VMs (albeit we can turn it on). All the VMs has filebeat installation. We have an ELK stack separately deployed. What I have found during working on this: the podman (installation here) supports only k8s-file and journald logging (problem #1: the easiest way would be to use json-file logging driver combined with docker/podman socket, this could not be achieved here) the podman socket belongs to the podman user who runs those rootless containers so it is not really visible for the others, even the root could not see the running containers without the podman socket – I was able to work this around (so the root was able to list the running containers), but I don’t think so / could not believe that this should be the industrial standard solution switching to journald and using the journalbeat: this may work, but I don’t know that this can be combined with container metadata collecting that would be required to be able to distinguish the VM logs from the container logs I am looking for a solution for this setup that would make the centralized logging working in the asiest way.

traffic for modcluster from both of my servers. I have also run the McastReceiverTest (src: [URL] ) via: java org.jgroups.tests.McastReceiverTest -mcast_addr 230.0.0.4 -port 45700 and have used the following command: printf ""GET / HTTP/1.0\r\n\r\n"" | nc -vu 230.0.0.4 45700 and see the UDP traffic coming through. I am not seeing anything for the jgroups from wildfly though. In my logs, when I look for the subscribed channels, I see ""Received new cluster view for channel server: [app-one:server-one|0] (1) [app-one:server-one]"" But I never see my second server on either instance. When I test, I have an F5 load balancer in front of both RedHat instances. I have a few assumptions that I am hoping to clear up: Do I need to have Apache enabled for Modcluster? I'd assume not as it appears to be used for load balancing if you don't have a separate balancing mechanism. Is Session Replication the same as running a ""hot-hot"" scenario so that 2 applications can run and keep a session alive? My understanding is that I should be able to log into the application on server A and server B would be able to keep that session alive as well. We are trying to prevent the need for session stickyness. Can this run in a multi-server environment or is it only for 2 instances on the same local machine? I would assume that it should not matter if this is across a local machine or on 2 separate physicals/vms behind the same firewall. Thank you. I found a solution which has been eluding me. The problem with my configuration was in my bind IP. I was using 127.0.0.1 for my jboss.bind.address as I had Apache in front of my Wildfly configuration. I changed the bind IP to the IP of the NIC (in my case it was a 10.* address).","Session Replication in Wildfly 10.1 I am trying to enable session replication in my Wildfly 10.1 application with distributable WARs.

When I test, I have an F5 load balancer in front of both RedHat instances. I have a few assumptions that I am hoping to clear up: Do I need to have Apache enabled for Modcluster?

I need to avoid the permissions of the starting directory changing, at all during this process, so a simple chmod -R followed by a non recursive chmod to reset the permissions on the starting directory isn't an option.

35485372,How do I run a puppet exec if a condition met?,"Just to give some details - building on AWS, using Puppet to handle DSC, and have bootstrapped Puppet so that it provisions, and installs Puppet on the newly provisioned node. I've been working with Puppet for a little amount of time now, and I find myself wanting to write a module that only executes on creation of a vm. My particular use case is that I want to install antivirus (specifically, Trend Micro Deep Security) onto a newly provisioned node, automagically via Puppet. The script to run this only requires a download, a run, and a couple of TMDS specific commands to activate itself etc. If I use Puppet, it will do this on every run (download, try to install, try to activate) which is definitely not what I want. However, I don't think that Puppet 'knows' about Trend Micro, or how to get it, or the URL etc. So I can't use something like: service { ""trend micro"": ensure => running, ensure => present, } Doing some research, and looking at blog posts , I know that the structure of my code should be something along the lines of (I know it's not correct): exec {'function_name': # the script that downloads/installs/activates etc. command => '/path/to/script.sh', onlyif => systemctl service_trendmicro, # which system should return 0 or 1 for pass/fail - I only want it to exec on 0 ofc. } My question is therefore: How do I put this together?","How do I run a puppet exec if a condition met?

Then I parse this data with some sed commands to get a list I can use properly 1.) Then I do a ping test, to see if the server is alive. If the server is decom. The idea behind this, is if the server is not pingable, I don't want it being reported on, or any attempt to be made to connect to it, as it is just wasting time.

EDIT: Here is what rpm shows about dependencies: # rpm -q --provides -p sub-package-1.1-455015.el7.x86_64.rpm sub-package sub-package = 1.1-455015.el7 sub-package(x86-64) = 1.1-455015.el7 # rpm -q --requires -p main-package-16.2-460032.el7.noarch.rpm | grep sub-package sub-package >= 1.1 Here is the older sub-package that's already installed: # rpm -q --provides sub-package sub-package sub-package = 1.0-455013.el7 sub-package(x86-64) = 1.0-455013.el7 Here is the relevant information in my spec file: $ grep sub-package main-package.spec Requires: sub-package >= 1.1 $ head -n4 sub-package.spec Summary: sub-package (...)

30904631,How to install WebSphere MQ resource adapter (wmq.jmsra.rar) in JBoss 6.2 EAP?,"Design: I have a queue manager (EXAMPLE.QM) with Server-connection channel (EXAMPLE.CHANNEL), request queue (EXAMPLE.TEST.QUEUE), and reply queue (EXAMPLE.TEST.REPLY). My application will be using a message driven bean (MDB) to listen on EXAMPLE.TEST.QUEUE. When message arrives an instance of MDB is created and business logic is done which includes quering databases and then the reply is put on the EXAMPLE.TEST.REPLY queue. This is one transaction. In the event of crashes or any failure the exception will be caught and everything will be rolled back. I wanted to do the connection pooling for both MQ and Databases on the server side. Setup: WebSphere MQ 7.0.1, JBoss 6.2 EAP, Java 1.7.0_21, IBM DB2 9.7 I obtained the wmq.jmsra.rar from the MQ_INSTALLATION_PATH\java\lib\jca and I also got the com.ibm.mqetclient.jar As per Redhat installation guide in order to support XATransactions I repackaged the wmq.jmsra.rar to include com.ibm.mqetclient.jar using command jar -uf wmq.jmsra.rar com.ibm.mqetclient.jar You can skip the next paragraph and look at the xml snippet provided below for same information. After doing so instead manually dropping the wmq.jmsra.rar into JBoss deployment directory I used the management console. I then went ahead and added in profile view under Resource adapters. I set Archive to wmq.jmsra.rar and TX to XATransaction. I then set the properties to the following: logWriterEnabled - true, maxConnections - 10, reconnectionRetryCount - 5, traceLevel - 6, traceEnabled - true, reconnectionRetryInterval - 300000, and connectionConcurrency - 5. After doing so I added a connection definition. I named it WMQ_ConnectionFactory, JNDI - java:jboss/WMQ_ConnectionFactory, and Connection Class - com.ibm.mq.connector.outbound.ManagedConnectionFactoryImpl. I set the properties as follow: port - 1414, hostName - localhost, channel - EXAMPLE.CHANNEL, transportType - BINDINGS_THEN_CLIENT, failIfQuiesce - true, and queueManager - EXAMPLE.QM. I then went on to add 2 Admin Objects. 1st I named EXAMPLE_REQ_Queue, JNDI - java:jboss/EXAMPLE_REQ_Queue, and Class name - com.ibm.mq.connector.outbound.MQQueueProxy. I have it the following properties: useJNDI - true, readAheadClosePolicy - ALL, startTimeout - 10000, destination - EXAMPLE.TEST.REQUEST, and destinationType - javax.jms.Queue. The 2nd admin object I named EXAMPLE_REP_Queue, JNDI - java:jboss/EXAMPLE_REP-Queue, and class name - com.ibm.mq.connector.outbound.MQQueueProxy.

25975529,Setup and Debugging of applications run under mod-mono-server4,"I have a c# application (servicebus) which runs on a private web server. Its basic job is to accept some web requests and create other processes to handle processing the data packages described in the requests. The processing is often ongoing and can take weeks. The servicebus will, occasionally, start consuming great amounts of CPU. That is, it is normally idle, getting 1 or 2 seconds of CPU time per day. When it gets into this strange mode, its consuming 100+% CPU all the time. At this point, a new instance of the servicebus gets spawned by apache if a new request comes in. At this point I will have two copies of the servicebus running (and possibly both handling processing requests -- i don't know). This is the normal process (via ps -aef ) : UID PID PPID C STIME TTY TIME CMD apache 8978 1 0 11:51 ? 00:00:01 /opt/mono/bin/mono /opt/mono/lib/mono/4.0/mod-mono-server4.exe --filename /tmp/mod_mono_server_default --applications /:/opt/ov/vespa/servicebus --nonstop As you can see, the application is a C# program (compiled with VS 2010 for .NET 4) running via mod-mono-server4 under mono. This is a redhat linux enterprise 6.5 system. After running for a while that process 'went crazy' and started consuming lots of CPU and mod-mono-server created a new instance. As you can see, I didn't find it until Monday morning after it had used over 2 days of CPU time. Here is the new ps -aef output : UID PID PPID C STIME TTY TIME CMD apache 8978 1 83 Sep19 ? 2-08:26:25 /opt/mono/bin/mono /opt/mono/lib/mono/4.0/mod-mono-server4.exe --filename /tmp/mod_mono_server_default --applications /:/opt/ov/vespa/servicebus --nonstop apache 32538 1 0 Sep21 ? 00:00:00 /opt/mono/bin/mono /opt/mono/lib/mono/4.0/mod-mono-server4.exe --filename /tmp/mod_mono_server_default --applications /:/opt/ov/vespa/servicebus --nonstop In case you need to see how the application is configured, I have the snippet from the conf.d file for the application : # The user and group need to be set before mod_mono.conf is loaded. User apache Group apache # Service Bus setup Include /etc/httpd/conf/mod_mono.conf Listen 8081 <VirtualHost *:8081> DocumentRoot /opt/ov/vespa/servicebus MonoServerPath default /opt/mono/bin/mod-mono-server4 MonoApplications ""/:/opt/ov/vespa/servicebus"" <Location ""/""> SetHandler mono Allow from all </Location> </VirtualHost> The basic question is... how do I go about debugging this and finding what is wrong with my application? That, however is a bit vague. Normally, I would want to put mono into debug mod and then when it gets into this strange mode I would use kill -ABRT to get a core dump out of it. I assume I could then find a for loop/while loop/etc which is stuck and fix my bug. So, the real question is how do do that? Is that process PID=8978 actually my application being interpreted by mono or is it mono running mod-mono-server4.exe? Or is it mono interpreting mod-mono-server4.exe which in turn is interpreting servicebus? Where in the apache configuration files do I put in the arguments to mono so I can get the --debug I desire. Normally to debug I would need a process like : /opt/mono/bin/mono --debug /opt/test/testapp.exe So, I need to get a --debug into the command line and sort out which PID to actually kill. Then I can use techniques from [URL] to debug the core file. NOTE: I have tried putting in MonoMaxCPUTime and MonoAutoRestartTime directives into the apache conf files to cure this. The problem is, when everything is nominal, they work fine. Once it gets into this bad state(consuming a ton of CPU), the restart fails. Or rather it succeeds in creating a new process but fails to delete the old one (basically the state I am already in). Debugging so far : I see my log files for PID=8979 stops on 9/21 at 03:27. Given that it often generates a 200% or 300% CPU or more that could easily be the time of the 'crash'. Looking in the apache logs I found an unusual event at that time. A dump of the log is below : ... [Sun Sep 21 03:28:01 2014] [notice] SIGHUP received.

This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. ================================================================= Which I think means the process had a seg fault and was trying to dump core or something and stuck trying to do that? Or did it get a sig ABRT while processing a sig SEGV? In either case, that's a dump of mono, right? I did a find of the full file system and no core was generated so I'm not sure how apache/gdb managed this. In case it matters I have RedHat 6.5, mono 2.10.8, gcc 4.4.7, mod-mono-server4.exe 2.10.0.0 Basically this boils down to these questions. How do I get --debug into the mono commands that apache issues? How do I get apache to save the core files it encounters instead of automatically running gdb on them (as I need to issue more complex commands to get at the underlying c# code)? What does the command line for my servicebus mean? That is why/how come the mod-mono-server4 isn't a completely separate process from my servicebus? How does the MMS fit into the mono interpreting servicebus processing chain Or am I totally wrong and will the answers to those questions not help me?","Setup and Debugging of applications run under mod-mono-server4 I have a c# application (servicebus) which runs on a private web server. Its basic job is to accept some web requests and create other processes to handle processing the data packages described in the requests. The processing is often ongoing and can take weeks. The servicebus will, occasionally, start consuming great amounts of CPU. That is, it is normally idle, getting 1 or 2 seconds of CPU time per day. When it gets into this strange mode, its consuming 100+% CPU all the time. At this point, a new instance of the servicebus gets spawned by apache if a new request comes in. At this point I will have two copies of the servicebus running (and possibly both handling processing requests -- i don't know). This is the normal process (via ps -aef ) : UID PID PPID C STIME TTY TIME CMD apache 8978 1 0 11:51 ? 00:00:01 /opt/mono/bin/mono /opt/mono/lib/mono/4.0/mod-mono-server4.exe --filename /tmp/mod_mono_server_default --applications /:/opt/ov/vespa/servicebus --nonstop As you can see, the application is a C# program (compiled with VS 2010 for .NET 4) running via mod-mono-server4 under mono. This is a redhat linux enterprise 6.5 system. After running for a while that process 'went crazy' and started consuming lots of CPU and mod-mono-server created a new instance. As you can see, I didn't find it until Monday morning after it had used over 2 days of CPU time. Here is the new ps -aef output : UID PID PPID C STIME TTY TIME CMD apache 8978 1 83 Sep19 ? 2-08:26:25 /opt/mono/bin/mono /opt/mono/lib/mono/4.0/mod-mono-server4.exe --filename /tmp/mod_mono_server_default --applications /:/opt/ov/vespa/servicebus --nonstop apache 32538 1 0 Sep21 ? 00:00:00 /opt/mono/bin/mono /opt/mono/lib/mono/4.0/mod-mono-server4.exe --filename /tmp/mod_mono_server_default --applications /:/opt/ov/vespa/servicebus --nonstop In case you need to see how the application is configured, I have the snippet from the conf.d file for the application : # The user and group need to be set before mod_mono.conf is loaded. User apache Group apache # Service Bus setup Include /etc/httpd/conf/mod_mono.conf Listen 8081 <VirtualHost *:8081> DocumentRoot /opt/ov/vespa/servicebus MonoServerPath default /opt/mono/bin/mod-mono-server4 MonoApplications ""/:/opt/ov/vespa/servicebus"" <Location ""/""> SetHandler mono Allow from all </Location> </VirtualHost> The basic question is... how do I go about debugging this and finding what is wrong with my application? That, however is a bit vague. Normally, I would want to put mono into debug mod and then when it gets into this strange mode I would use kill -ABRT to get a core dump out of it. I assume I could then find a for loop/while loop/etc which is stuck and fix my bug. So, the real question is how do do that? Is that process PID=8978 actually my application being interpreted by mono or is it mono running mod-mono-server4.exe? Or is it mono interpreting mod-mono-server4.exe which in turn is interpreting servicebus? Where in the apache configuration files do I put in the arguments to mono so I can get the --debug I desire. Normally to debug I would need a process like : /opt/mono/bin/mono --debug /opt/test/testapp.exe So, I need to get a --debug into the command line and sort out which PID to actually kill. Then I can use techniques from [URL] to debug the core file. NOTE: I have tried putting in MonoMaxCPUTime and MonoAutoRestartTime directives into the apache conf files to cure this. The problem is, when everything is nominal, they work fine. Once it gets into this bad state(consuming a ton of CPU), the restart fails. Or rather it succeeds in creating a new process but fails to delete the old one (basically the state I am already in). Debugging so far : I see my log files for PID=8979 stops on 9/21 at 03:27. Given that it often generates a 200% or 300% CPU or more that could easily be the time of the 'crash'. Looking in the apache logs I found an unusual event at that time. A dump of the log is below : ... [Sun Sep 21 03:28:01 2014] [notice] SIGHUP received.

This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. ================================================================= Which I think means the process had a seg fault and was trying to dump core or something and stuck trying to do that? Or did it get a sig ABRT while processing a sig SEGV? In either case, that's a dump of mono, right? I did a find of the full file system and no core was generated so I'm not sure how apache/gdb managed this. In case it matters I have RedHat 6.5, mono 2.10.8, gcc 4.4.7, mod-mono-server4.exe 2.10.0.0 Basically this boils down to these questions. How do I get --debug into the mono commands that apache issues? How do I get apache to save the core files it encounters instead of automatically running gdb on them (as I need to issue more complex commands to get at the underlying c# code)? What does the command line for my servicebus mean? That is why/how come the mod-mono-server4 isn't a completely separate process from my servicebus? How does the MMS fit into the mono interpreting servicebus processing chain Or am I totally wrong and will the answers to those questions not help me?","linux, apache, mono, redhat, mod-mono",2,1161,1,https://stackoverflow.com/questions/25975529/setup-and-debugging-of-applications-run-under-mod-mono-server4

12785964,Makefile isn&#39;t rebuilding dependencies?,"Fair warning: I'm something of a newb at using makefiles, so this may be something obvious. What I'm trying to do is to use make to run a third-party code generation tool when and only when the source files for that generation tool (call them .abc files) change. I referenced the example at [URL] which shows how to build MD5s, and I tweaked the idea a bit: File: abc.mk target = all files := $(wildcard Abc/*.abc) bltfiles := $files $(addsuffix .built,$files) all: $bltfiles %.built: %.abc %.abc.md5 @echo ""Building $*"" @ #Command that generates code from a .abc file @touch $@ %.md5: FORCE @echo ""Checking $* for changes..."" @ #Command to update the .md5 file, if the sum of the .abc file is different FORCE: What I'm intending to happen is for each .abc file to have two auxilary files: .abc.built & .abc.md5 . The .built file is just a dummy target & timestamp for the last time it was built, as the code produced by the generation tool cannot be readily defined as a target. The .md5 file contains a hash of the last known content of the .abc file. It should only be updated when the hash of the file changes. However, the .built file is only created if it doesn't exist. The .md5 rule never runs at all, and the .built rule doesn't re-build even if the .abc file has a newer timestamp. Am I doing something wrong? Update: For posterity, here's the version I got to work: File: abc.mk # Call this makefile as: make all --file=abc.mk # Default Target target = all COMP_ABC_FILES := $(wildcard Abc/*.abc) COMP_BLT_FILES := $(COMP_ABC_FILES) $(addsuffix .built, $(COMP_ABC_FILES) ) # This line is needed to keep make from deleting intermediary output files: .SECONDARY: # Targets: .PHONY: all all: $(COMP_BLT_FILES) Abc/%.abc.built: Abc/%.abc Abc/%.abc.md5 @echo ""Building $*"" @ #Command that generates code from a .abc file @touch $@ %.md5: FORCE @echo ""Checking $* for changes..."" @$(if $(filter-out $(shell cat $@ 2>/dev/null),$(shell md5sum $*)),md5sum $* > $@) # Empty rule to force re-build of files: FORCE: clean: @echo ""Cleaning .built & .md5 files..."" @rm Abc/*.built @rm Abc/*.md5","Makefile isn&#39;t rebuilding dependencies?

I referenced the example at [URL] which shows how to build MD5s, and I tweaked the idea a bit: File: abc.mk target = all files := $(wildcard Abc/*.abc) bltfiles := $files $(addsuffix .built,$files) all: $bltfiles %.built: %.abc %.abc.md5 @echo ""Building $*"" @ #Command that generates code from a .abc file @touch $@ %.md5: FORCE @echo ""Checking $* for changes..."" @ #Command to update the .md5 file, if the sum of the .abc file is different FORCE: What I'm intending to happen is for each .abc file to have two auxilary files: .abc.built & .abc.md5 . The .built file is just a dummy target & timestamp for the last time it was built, as the code produced by the generation tool cannot be readily defined as a target. The .md5 file contains a hash of the last known content of the .abc file. It should only be updated when the hash of the file changes. However, the .built file is only created if it doesn't exist. The .md5 rule never runs at all, and the .built rule doesn't re-build even if the .abc file has a newer timestamp. Am I doing something wrong? Update: For posterity, here's the version I got to work: File: abc.mk # Call this makefile as: make all --file=abc.mk # Default Target target = all COMP_ABC_FILES := $(wildcard Abc/*.abc) COMP_BLT_FILES := $(COMP_ABC_FILES) $(addsuffix .built, $(COMP_ABC_FILES) ) # This line is needed to keep make from deleting intermediary output files: .SECONDARY: # Targets: .PHONY: all all: $(COMP_BLT_FILES) Abc/%.abc.built: Abc/%.abc Abc/%.abc.md5 @echo ""Building $*"" @ #Command that generates code from a .abc file @touch $@ %.md5: FORCE @echo ""Checking $* for changes..."" @$(if $(filter-out $(shell cat $@ 2>/dev/null),$(shell md5sum $*)),md5sum $* > $@) # Empty rule to force re-build of files: FORCE: clean: @echo ""Cleaning .built & .md5 files..."" @rm Abc/*.built @rm Abc/*.md5","linux, makefile, dependencies, redhat",2,379,2,https://stackoverflow.com/questions/12785964/makefile-isnt-rebuilding-dependencies

4147276,Multiple Process InitScript Logic,"I am developing initscripts for some of our software, and am having difficulty deciding how I should use it for a particular piece. We have homegrown software responsible for passing data around out network, it's built on a standard pubsub model. There is a publisher process (two, actually, for two different use cases), a broker process, and a subscriber process). Any combination of these processes, and even multiple of the same process, can run simultaneously on a given box. I'm having trouble deciding how best to allow this to be configured. Since it can vary from box to box, that will likely go into /etc/sysconfig/pubsub which will be read in by the initscript. The only things I will have to allow to be configured is (1) the process name, which is one of log_publish, dir_publish, broker, subscribe, and (2) the configuration file that corresponds to that particular process. I wish to avoid telling people how to modify the initscript per box in order to change the list of running processes, so this unique configuration file per box is the best way I can come up with to accomplish that. I assume this also means that I will have to have some kind of unique identifier per process on the box, as I intend to use the touch /var/lock/subsys/* method that most RedHat initscripts use already to lock a process from running twice. Knowing this, I know the identifier can't always be random, otherwise it will never be effective in order to prevent duplicate processes with the same configuration file (because, again, I need to be able to run multiple processes with different configuration files). I have no idea how best to represent this in configuration.","Multiple Process InitScript Logic I am developing initscripts for some of our software, and am having difficulty deciding how I should use it for a particular piece.

55280211,Writing to page mapped dmas in kernel,"I've been working on modifying the intel ixgbe kernel driver to function with my PCIe device (FPGA but that's not super important). The kernel and the PCIe device all negotiate quite well, configuration headers are passed along and communication seems to function. However attempting to write DMA_FROM_DEVICE I have a slight problem that I don't understand and I'm hoping for help. rx_ring->desc = dma_alloc_coherent(dev, ///This function allocates dma space of size size for handle dma on device dev with flag GFP KERNEL rx_ring->size, &rx_ring->dma, ///This dma handle may be cast to unsigned integer of the same bus width and given to dev as the DMA base address GFP_KERNEL); page = dev_alloc_pages(0); dma = dma_map_page(rx_ring->dev, page, 0, acc_rx_pg_size(rx_ring), DMA_FROM_DEVICE); //Writing to the PCI device the base address to place data into. writel(q_vector->adapter->rx_ring[0]->dma >> 32, q_vector->adapter->hw_region2.hw_addr+0x08+ACC_PCI_IPCONT_DATA_OFFSET); writel(q_vector->adapter->rx_ring[0]->dma & 0xFFFFFFFF, q_vector->adapter->hw_region2.hw_addr+0x0C+ACC_PCI_IPCONT_DATA_OFFSET); //This will perfectly read data I place onto the PCIe bus. rx_ring->desc->wb.upper.length //This seems to read some garbage memory. dma_sync_single_range_for_cpu(rx_ring->dev, rx_buffer->dma, rx_buffer->page_offset, acc_rx_bufsz(rx_ring), DMA_FROM_DEVICE); unsigned char *va = page_address(page) + rx_buffer->page_offset; memcpy(__skb_put(skb, size), va, ALIGN(size, sizeof(long))); //Some code later dma_sync_single_range_for_device(rx_ring->dev, new_buff->dma, new_buff->page_offset, acc_rx_bufsz(rx_ring), DMA_FROM_DEVICE); I've tried to purge code down to just the points of interest but here's the brief run down. I allocate space for the dma creating the virtual and bus address via the dma_alloc_coherent function. I create a page of memory for the dma and map this page to the dma via the dev_alloc_pages and dma_map_page commands. I pass the dma bus address to my PCIe device so it can write to the proper offset via the writel commands (I know iowrite32 but this is on redhat). From here there are 2 ways that the origonal ixgbe driver reads data from the PCIe bus. First it directly reads from the dma's allocated virtual address (desc), but this is only used for configuration information (in the driver I am working off of). The second method is via use page_address(page) to I believe get a virtual address for the page of memory. The problem is there is only garbage memory there. So here is my confusion. Where is page pointing to and how do I place data into page via the PCI bus? I assumed that dma_map_page would sort of merge the 2 virtual addresses into 1 so my write into the dma's bus address would collide into the page but this doesn't seem to be the case. What base address should my PCI device be writing from to align into this page of memory? I'm working on redhat, specifically Centos kernel version 3.10.0 which makes for some problems since redhat kernel is very different from base kernel but hopefully someone can help. Thank you for any pointers. EDIT: Added dma_sync calls which I forgot to include in original post. EDIT2: Added a more complete code base. As a note I'm still not including some of the struct definitions or top function calls (like probe for instance), but hopefully this will be a lot more complete.

The kernel and the PCIe device all negotiate quite well, configuration headers are passed along and communication seems to function. However attempting to write DMA_FROM_DEVICE I have a slight problem that I don't understand and I'm hoping for help. rx_ring->desc = dma_alloc_coherent(dev, ///This function allocates dma space of size size for handle dma on device dev with flag GFP KERNEL rx_ring->size, &rx_ring->dma, ///This dma handle may be cast to unsigned integer of the same bus width and given to dev as the DMA base address GFP_KERNEL); page = dev_alloc_pages(0); dma = dma_map_page(rx_ring->dev, page, 0, acc_rx_pg_size(rx_ring), DMA_FROM_DEVICE); //Writing to the PCI device the base address to place data into. writel(q_vector->adapter->rx_ring[0]->dma >> 32, q_vector->adapter->hw_region2.hw_addr+0x08+ACC_PCI_IPCONT_DATA_OFFSET); writel(q_vector->adapter->rx_ring[0]->dma & 0xFFFFFFFF, q_vector->adapter->hw_region2.hw_addr+0x0C+ACC_PCI_IPCONT_DATA_OFFSET); //This will perfectly read data I place onto the PCIe bus. rx_ring->desc->wb.upper.length //This seems to read some garbage memory. dma_sync_single_range_for_cpu(rx_ring->dev, rx_buffer->dma, rx_buffer->page_offset, acc_rx_bufsz(rx_ring), DMA_FROM_DEVICE); unsigned char *va = page_address(page) + rx_buffer->page_offset; memcpy(__skb_put(skb, size), va, ALIGN(size, sizeof(long))); //Some code later dma_sync_single_range_for_device(rx_ring->dev, new_buff->dma, new_buff->page_offset, acc_rx_bufsz(rx_ring), DMA_FROM_DEVICE); I've tried to purge code down to just the points of interest but here's the brief run down. I allocate space for the dma creating the virtual and bus address via the dma_alloc_coherent function. I create a page of memory for the dma and map this page to the dma via the dev_alloc_pages and dma_map_page commands. I pass the dma bus address to my PCIe device so it can write to the proper offset via the writel commands (I know iowrite32 but this is on redhat). From here there are 2 ways that the origonal ixgbe driver reads data from the PCIe bus. First it directly reads from the dma's allocated virtual address (desc), but this is only used for configuration information (in the driver I am working off of). The second method is via use page_address(page) to I believe get a virtual address for the page of memory. The problem is there is only garbage memory there. So here is my confusion. Where is page pointing to and how do I place data into page via the PCI bus? I assumed that dma_map_page would sort of merge the 2 virtual addresses into 1 so my write into the dma's bus address would collide into the page but this doesn't seem to be the case. What base address should my PCI device be writing from to align into this page of memory? I'm working on redhat, specifically Centos kernel version 3.10.0 which makes for some problems since redhat kernel is very different from base kernel but hopefully someone can help. Thank you for any pointers. EDIT: Added dma_sync calls which I forgot to include in original post. EDIT2: Added a more complete code base. As a note I'm still not including some of the struct definitions or top function calls (like probe for instance), but hopefully this will be a lot more complete.

55095072,Openshift 3.11 logging to external ElasticSearch instance,"I have an external ElasticSearch instance that I'd like Fluentd and Kibana to leverage accordingly in OSE 3.11. The ES instance is insecure at the moment, as this is simply a internal pilot. Based on the OSE docs here ( [URL] ), I should be able to update a number of ES_* variables accordingly in the ElasticSearch deployment config.

45821749,RHEL 6 SCL script not sourcing for normal user,"I'm using devtoolset-2 on a rhel 6.9 installation so I can use the gcc 4.8 version that devtoolset-2 offers. On a previous rhel 6.2 installation (on a VM) I was able to enable devtoolset-2's gcc by adding a script in /etc/profile.d/ to source devtoolset-2's enable script: $ cat /etc/profile.d/devtoolset2.sh #!/bin/bash source scl_source enable devtoolset-2 That worked great, giving me access to gcc 4.8 for any terminal window I opened. Now on this new 6.9 install (on real hardware) I've tried the same script in the same location, but it never sources. New terminal windows always default to the system's gcc 4.4. I can, however, manually source the enable script and it does work: $ gcc --version gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-18) $ source scl_source enable devtoolset-2 $ gcc --version gcc (GCC) 4.8.2 20140120 (Red Hat 4.8.2-15) After googling I tried sourcing the script with several different commands as well: . /opt/rh/devtoolset-2/enable source /opt/rh/devtoolset-2/enable ... etc. I want this setting to apply to all user's terminals, but just to be complete I tried sourcing it from both my .bashrc and .bash_profile scripts and neither worked for my user. One last thing I noticed is that if I logged in as root, instead of a normal user, the script in /etc/profile.d/ did source devtoolset-2 just fine. Any ideas why it would source automatically for root, but not any other users?","RHEL 6 SCL script not sourcing for normal user I'm using devtoolset-2 on a rhel 6.9 installation so I can use the gcc 4.8 version that devtoolset-2 offers.

44548661,Pip install significantly slower on Python 3.5 versus 2.7 (RHEL),"I'm currently running Red Hat 7.3 and installed Python 3.5 from the SCL (www.softwarecollections.org/en/scls/rhscl/rh-python35/). When I attempt to pip install C intensive packages such as numpy and pandas, the install process on Python 3.5 is taking significantly longer than when I attempt to install the same packages in the native Python 2.7 installation (6 minutes per package versus ~10 seconds). I have some automated processes that are building and rebuilding virtual environments on a frequent basis, so this is having a huge impact on the overall performance. Does anyone know why these installations are taking significantly longer in Python 3.5? Any help would be greatly appreciated. Here's a snippet of the 'pip install numpy -v' on both versions. The obvious thing that jumps out at me is the GCC building that occurs in 3.5 and not in 2.7 but I'm not sure why...

Removing source in /tmp/pip-build-12s9oqxb/numpy Successfully installed numpy-1.13.0 Cleaning up...","Pip install significantly slower on Python 3.5 versus 2.7 (RHEL) I'm currently running Red Hat 7.3 and installed Python 3.5 from the SCL (www.softwarecollections.org/en/scls/rhscl/rh-python35/). When I attempt to pip install C intensive packages such as numpy and pandas, the install process on Python 3.5 is taking significantly longer than when I attempt to install the same packages in the native Python 2.7 installation (6 minutes per package versus ~10 seconds). I have some automated processes that are building and rebuilding virtual environments on a frequent basis, so this is having a huge impact on the overall performance. Does anyone know why these installations are taking significantly longer in Python 3.5? Any help would be greatly appreciated. Here's a snippet of the 'pip install numpy -v' on both versions. The obvious thing that jumps out at me is the GCC building that occurs in 3.5 and not in 2.7 but I'm not sure why...

Do you wish to continue? This is what I have experienced on every other machine I've used nano on Observed output : Nano executes step 2 without warning. Only when I try to save the file does it alert me that someone else has the file open. Issue : This is an issue because sometimes I: open file x in instance A modify but don't save do something else forget that I haven't saved my modifications to file x, and forget that it's still open open file x in instance B make more modifications in instance B try to save be warned that 2 instances are opened realise that I've made changes to 2 different unsaved instances of the one file","warnings, edit, redhat, nano",2,1137,0,https://stackoverflow.com/questions/43860825/nano-text-editor-not-warning-when-opening-file-already-open

38576638,Transfer i/o files &amp; invoke scripts betwen 2 applications running in different Red Hat Linux Server,"Issue Background: Moving a Java/J2EE application from dedicated RedHat Linux server to cloud RedHat Linux server. I am analysing the Batch processing jobs involved in this application to implement similar processing in cloud environment. Current Approach: We have 2 applications App1 & App2 both are in same RedHat Linux server. Both applications have shared directories in the same server. Also Appl can call shell scripts in App2's directory to get some job done. App2's process: External system send input file(.DAT) to App2 via NDM Jobs. Received input file(.DAT) will be placed in App2's input file directory. Process the records in file using Java/J2EE program/component Generate the outputfile. Place it in App1's shared directory. App1 has a filewatcher pointed to this directory to consume this file. Upcoming approach: App2 will be moved to cloud Red Hat Linux server. App2 will be running in atleast 2 nodes. Challenges: External system job still point to same old directory in non cloud Linux server. After processing, output file must be in App1's shared directory. Expectation: App2's process running in cloud is, expected to read & process this file. Request you all to suggest a best approach for this requirement. Can we have FTP or REST-webservice to read the input file from non cloud Linux server? 2) App1 has business requirement to call shell scripts in App2. How can we provide a service to call App2's shell script located in cloud server. I am new to cloud. Please excuse me if my questions are irrelevant or trivial. Thank You In Advance.","Transfer i/o files &amp; invoke scripts betwen 2 applications running in different Red Hat Linux Server Issue Background: Moving a Java/J2EE application from dedicated RedHat Linux server to cloud RedHat Linux server. I am analysing the Batch processing jobs involved in this application to implement similar processing in cloud environment. Current Approach: We have 2 applications App1 & App2 both are in same RedHat Linux server. Both applications have shared directories in the same server. Also Appl can call shell scripts in App2's directory to get some job done. App2's process: External system send input file(.DAT) to App2 via NDM Jobs. Received input file(.DAT) will be placed in App2's input file directory. Process the records in file using Java/J2EE program/component Generate the outputfile. Place it in App1's shared directory. App1 has a filewatcher pointed to this directory to consume this file. Upcoming approach: App2 will be moved to cloud Red Hat Linux server. App2 will be running in atleast 2 nodes. Challenges: External system job still point to same old directory in non cloud Linux server. After processing, output file must be in App1's shared directory. Expectation: App2's process running in cloud is, expected to read & process this file. Request you all to suggest a best approach for this requirement.

The first one provides REST interfaces and a UI to manage the operating system (start/stop services, execute system command using suid, modify system settings, etc.). This httpd service (running on port 5555) will only be accessible from a certain ip range (firewall) since it will be used for administrative purposes. The second httpd service (port 80 and 443) will be visible on the Internet. It will serve a web application to external customers. The first httpd needs selinux policies that give it more access to the OS files/processes. The second needs selinux policies that are strict to what it is allowed to do within its context. The second needs to be this way for better web application security and prevent any web app exploits from even being able to touch the OS. Both of the httpd processes are running as different users. Can selinux be used with 2 different sets of policies for the same httpd executable? How do I/is it possible to set the httpd process context to switch to another set of policies when httpd starts? Is it just a matter of making a copy of the httpd binary and change its selinux context that uses all new policies (relabel the httpd binary, but I'm sure it will take more than this)? What are the steps to copy the existing httpd selinux settings to a new name? I think this comes down to needing a httpdpublic and httpdprivate selinux context.

17319561,Determine list of non-OS packages installed on a RedHat Linux machine,"I have been tasked with identifying new (non-operating system) software installed on several Red Hat Enterprise Linux (RHEL) machines. Can anyone suggest an efficient way to do this? The way I was doing it is manually comparing the list of installed software with the list on Red Hat's FTP site for the relevant operating system: ftp://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/ The problems I am encountering with this method is it is tedious / timeconsuming, and just the source packages are listed (e.g. I can't tell if avahi-glib is installed as part of the avahi package). If anyone can suggest a more efficient way to identify the software that doesn't come with the operating system on a RHEL machine, it would be greatly appreciated! Here is what I have come up with so far as a more efficient method (though I still haven't figured out the last part, and there may be more efficient methods). If anyone can help me with the last step of this method, or can share a better method, it would be greatly appreciated! New method (work in progress): Copy the list of packages from Red Hat's FTP site into a text file (OSPackages.txt). To fix the problem of just source RPMs being listed, also copy the list of files from the relevant corresponding version in [URL] into a text file, and merge this data with OSPackages.txt. Do a rpm -qa > list1, yum -y list installed > list2, ls /usr/bin > list3, ls /usr/share > list4, ls /usr/lib > list5. Use cat to merge all the listX files together into InstalledPackages.txt. Use sort to sort out the unique entries, perhaps like: sort -u -k 1 InstalledPackages.txt > SortedInstalledPackages.txt Do a diff between SortedInstalledPackages.txt and OSPackages.txt using a regular expression (-I regexp) to identify the package names (and eliminate the version numbers). I would need to also do a ""one way diff"", e.g. ignore the extra OS packages in OSPackages.txt that do not appear in the installed packages file. Note: I asked the following question to help me with this part, and believe I am now fairly close to a solution: How do I do a one way diff in Linux? If diff (or another command) can perform the last step, it should produce a list of packages that don't come on the OS. This is the step I am stuck on and would appreciate further help.

to 80. But whenever I try to format the code, it splits my line at 120. There is no other formatter in place and there is no other property that sets the lineSplit to 120. I tried searching all VSCode properties but I could not find anything set to 120. Also, other properties of this xml file are working , for example , line splits on comments happen on 80 as mentioned in the xml file. I am using the RedHat extension for Java for VSCode.","Formatter not working in VSCode on lineSplit My settings for VSCode are as follows - { ""editor.defaultFormatter"": ""redhat.java"",

to 80. But whenever I try to format the code, it splits my line at 120. There is no other formatter in place and there is no other property that sets the lineSplit to 120. I tried searching all VSCode properties but I could not find anything set to 120. Also, other properties of this xml file are working , for example , line splits on comments happen on 80 as mentioned in the xml file. I am using the RedHat extension for Java for VSCode.","format, redhat, visual-studio-code",1,2713,2,https://stackoverflow.com/questions/56636516/formatter-not-working-in-vscode-on-linesplit

This is on RHEL 5.2 (Tikanga). The crash report is at [URL] and the consistent parts of the crash are: a SIGSEGV is being thrown on libjvm.so eden space is always full (100%) JVM runs with the following options: CATALINA_OPTS=""-server -Xms512m -Xmx1024m -Djava.awt.headless=true"" I've also tested the memory for hardware problems using [URL] for 48 hours (14 passes of the whole memory) without any error. I've enabled -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps to inspect for any GC trends or space exhaustion but there is nothing suspicious there. GC and full GC happens at predicable intervals, almost always freeing the same amount of memory capacities. My application does not, directly, use any native code. Any ideas of where I should look next? Edit - more info : 1) There is no client vm in this JDK: [foo@localhost ~]$ java -version -server java version ""1.6.0_18"" Java(TM) SE Runtime Environment (build 1.6.0_18-b07) Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode) [foo@localhost ~]$ java -version -client java version ""1.6.0_18"" Java(TM) SE Runtime Environment (build 1.6.0_18-b07) Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode) 2) Changing the O/S is not possible. 3) I don't want to change the JMeter stress test variables since this could hide the problem. Since I've got a use case (the current stress test scenario) which crashes the JVM I'd like to fix the crash and not change the test. 4) I've done static analysis on my application but nothing serious came up. 5) The memory does not grow over time. The memory usage equilibrates very quickly (after startup) at a very steady trend which does not seem suspicious. 6) /var/log/messages does not contain any useful information before or during the time of the crash More info : Forgot to mention that there was an apache (2.2.14) fronting tomcat using mod_jk 1.2.28. Right now I'm running the test without apache just in case the JVM crash relates to the mod_jk native code which connects to JVM (tomcat connector). After that (if JVM crashes again) I'll try removing some components from my application (caching, lucene, quartz) and later on will try using jetty. Since the crash is currently happening anytime between 4 hours to 8 days, it may take a lot of time to find out what's going on.","JVM crashes under stress on RHEL 5.2 I've got (the currently latest) jdk 1.6.0.18 crashing while running a web application on (the currently latest) tomcat 6.0.24 unexpectedly after 4 to 24 hours 4 hours to 8 days of stress testing (30 threads hitting the app at 6 mil. pageviews/day).

Edit - more info : 1) There is no client vm in this JDK: [foo@localhost ~]$ java -version -server java version ""1.6.0_18"" Java(TM) SE Runtime Environment (build 1.6.0_18-b07) Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode) [foo@localhost ~]$ java -version -client java version ""1.6.0_18"" Java(TM) SE Runtime Environment (build 1.6.0_18-b07) Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode) 2) Changing the O/S is not possible. 3) I don't want to change the JMeter stress test variables since this could hide the problem. Since I've got a use case (the current stress test scenario) which crashes the JVM I'd like to fix the crash and not change the test. 4) I've done static analysis on my application but nothing serious came up. 5) The memory does not grow over time. The memory usage equilibrates very quickly (after startup) at a very steady trend which does not seem suspicious. 6) /var/log/messages does not contain any useful information before or during the time of the crash More info : Forgot to mention that there was an apache (2.2.14) fronting tomcat using mod_jk 1.2.28. Right now I'm running the test without apache just in case the JVM crash relates to the mod_jk native code which connects to JVM (tomcat connector). After that (if JVM crashes again) I'll try removing some components from my application (caching, lucene, quartz) and later on will try using jetty. Since the crash is currently happening anytime between 4 hours to 8 days, it may take a lot of time to find out what's going on.","java, jvm, crash, segmentation-fault, rhel",10,2921,7,https://stackoverflow.com/questions/2247340/jvm-crashes-under-stress-on-rhel-5-2

12710544,Python multiprocessing doesn&#39;t use all cores on RHEL6,"I have been trying to use the python multiprocessing package to speed up some physics simulations I'm doing by taking advantage of the multiple cores of my computer. I noticed that when I run my simulation at most 3 of the 12 cores are used. In fact, when I start the simulation it initially uses 3 of the cores, and then after a while it goes to 1 core. Sometimes only one or two cores are used from the start. I have not been able to figure out why (I basically change nothing, except closing a few terminal windows (without any active processes)). (The OS is Red Hat Enterprise Linux 6.0, Python version is 2.6.5.) I experimented by varying the number of chunks (between 2 and 120) into which the work is split (i.e. the number of processes that are created), but this seems to have no effect. I looked for info about this problem online and read through most of the related questions on this site (e.g. one , two ) but could not find a solution. (Edit: I just tried running the code under Windows 7 and it's using all available cores alright. I still want to fix this for the RHEL, though.)

Therefore whenever I run any podman commands, it fails with cannot write to /home/<user> How can I use podman when there is no possibility of a home directory? Seems a big flaw in podman to enforce this requirement. Unless of course, someone can tell me what the change is I need to make? cheers!","rhel, selinux, podman",6,5447,2,https://stackoverflow.com/questions/61053867/how-to-run-podman-when-no-home-directory

6113423,Linux thread scheduling differences on multi-core systems?,"We have several latency-sensitive ""pipeline""-style programs that have a measurable performance degredation when run on one Linux kernel versus another. In particular, we see better performance with the 2.6.9 CentOS 4.x (RHEL4) kernel, and worse performance with the 2.6.18 kernel from CentOS 5.x (RHEL5). By ""pipeline"" program, I mean one that has multiple threads. The mutiple threads work on shared data. Between each thread, there is a queue. So thread A gets data, pushes into Qab, thread B pulls from Qab, does some processing, then pushes into Qbc, thread C pulls from Qbc, etc. The initial data is from the network (generated by a 3rd party). We basically measure the time from when the data is received to when the last thread performs its task. In our application, we see an increase of anywhere from 20 to 50 microseconds when moving from CentOS 4 to CentOS 5. I have used a few methods of profiling our application, and determined that the added latency on CentOS 5 comes from queue operations (in particular, popping). However, I can improve performance on CentOS 5 (to be the same as CentOS 4) by using taskset to bind the program to a subset of the available cores. So it appers to me, between CentOS 4 and 5, there was some change (presumably to the kernel) that caused threads to be scheduled differently (and this difference is suboptimal for our application). While I can ""solve"" this problem with taskset (or in code via sched_setaffinity()), my preference is to not have to do this. I'm hoping there's some kind of kernel tunable (or maybe collection of tunables) whose default was changed between versions. Anyone have any experience with this? Perhaps some more areas to investigate? Update: In this particular case, the issue was resolved by a BIOS update from the server vendor (Dell). I pulled my hair out quite a while on this one. Until I went back to the basics, and checked my vendor's BIOS updates. Suspiciously, one of the updates said something like ""improve performance in maximum performance mode"". Once I upgraded the BIOS, CentOS 5 was faster---generally speaking, but particularly in my queue tests, and actual production runs.","Linux thread scheduling differences on multi-core systems?

60762134,How to determine what is shutting down my Java app?,"I've got a Java8 application running on RHEL 6.10. This application registers a shutdown handler via the usual method: Thread shutdownThread = new Thread(()=>{ Logger.info(""Got shutdown signal""); // Do cleanup }); Runtime.getRuntime().addShutdownHook(shutdownThread); This application is kicked off by a Jenkins build (with the BUILD_ID env var set to dontkillme ). The application initializes successfully, but then after ~30 seconds the shutdown hook is called and the application terminates. I'm trying to figure out who is shutting me down and why.

I've also looked at /var/log/dmesg and /var/log/messages and don't see anything relevant there either. I don't think Jenkins would be killing me, both since I set BUILD_ID and also because the application dies while the ""parent"" Jenkins job is still running.

22311699,Trouble with OpenSSL on RHEL 6.3 and all Ruby installers,"OpenSSL does not appear to be compiling correctly when installing any version of Ruby on our RHEL 6.3 system. I have been trying to leave user installs of RVM behind and replace them with root installs via ruby-install and chruby. OpenSSL works okay in our RVM user installs (with the prescribed RVM fix) as well as in the built-in system install of Ruby 1.8.7 in /usr/bin . OpenSSL is broken in each Ruby version I have tried with ruby-install, ruby-build, and even RVM when using their latest suggested fix. 1.9.3-p392 (our prod version), 1.9 latest, and 2.1.0 current. I have tried every openssl fix/workaround I can find, such as the --with-openssl-dir=/some/dir config pointing to various openssl folders, but nothing works for me.

3358869,Running Zend Framework on PHP 5.1.6 - patch or fix for ksort()?,"I've built a ZF app using 1.10 for deployment on RHEL server in a corporate client, which has PHP 5.1.6. It won't run. I googled and now realise it's the version of PHP. I didn't realise ZF had a minimum requirement for PHP 5.2.4, and calls to HeadLink seem to be causing fatal error ""Call to undefined method Zend_View_Helper_Placeholder_Container::ksort()"": PHP Fatal error: Call to undefined method Zend_View_Helper_Placeholder_Container::ksort() in /library/ Zend/View/Helper/HeadLink.php on line 321 The client won't upgrade their PHP; I don't want to rewrite the app without ZF, and I'd rather not downgrade ZF to a grossly earlier version. Is there some patch I can use to add ksort() to ZF 1.10 to get around this? There may be other problems, but this is where I'm stuck right now. Any advice welcome Many thanks Ian EDIT: As I say in a comment below, I expect many people have hit this before and will keep on doing so as RHEL5 will be a standard in corporate environments for a good time to come. I was hoping for a link to an existing solution rather having to devise one from scratch. UPDATE: I used the patch linked to in the accepted answer and it fixed the problem for me. This is adding the following public method to Zend/View/Helper/Placeholder/Container/Abstract.php /** * Sort the array by key * * @return array */ public function ksort() { $items = $this->getArrayCopy(); return ksort($items); } There was one remaining issue; a PHP notice caused by a string conversion in Zend_View_Helper_Doctype.

We'll make sure the patch is versioned in the repo and documented obviously for future developers.","Running Zend Framework on PHP 5.1.6 - patch or fix for ksort()? I've built a ZF app using 1.10 for deployment on RHEL server in a corporate client, which has PHP 5.1.6. It won't run. I googled and now realise it's the version of PHP. I didn't realise ZF had a minimum requirement for PHP 5.2.4, and calls to HeadLink seem to be causing fatal error ""Call to undefined method Zend_View_Helper_Placeholder_Container::ksort()"": PHP Fatal error: Call to undefined method Zend_View_Helper_Placeholder_Container::ksort() in /library/ Zend/View/Helper/HeadLink.php on line 321 The client won't upgrade their PHP; I don't want to rewrite the app without ZF, and I'd rather not downgrade ZF to a grossly earlier version. Is there some patch I can use to add ksort() to ZF 1.10 to get around this? There may be other problems, but this is where I'm stuck right now. Any advice welcome Many thanks Ian EDIT: As I say in a comment below, I expect many people have hit this before and will keep on doing so as RHEL5 will be a standard in corporate environments for a good time to come. I was hoping for a link to an existing solution rather having to devise one from scratch. UPDATE: I used the patch linked to in the accepted answer and it fixed the problem for me. This is adding the following public method to Zend/View/Helper/Placeholder/Container/Abstract.php /** * Sort the array by key * * @return array */ public function ksort() { $items = $this->getArrayCopy(); return ksort($items); } There was one remaining issue; a PHP notice caused by a string conversion in Zend_View_Helper_Doctype. Comparing this function to similar ones above and below, this seems to be an error in the library public function isHtml5() { return (stristr($this->doctype(), '<!DOCTYPE html>') ? true : false); } Changed to: public function isHtml5() { return (stristr($this->getDoctype(), '<!DOCTYPE html>') ? true : false); } Patching the library itself was the last thing I would normally do, but in this case it got me out of a spot.

60982717,Shiny Server missing charts generated by R markdown file,"I have an R markdown file which I'd like to be available on my corporate Shiny Server. According to R Markdown: The Definitive Guide I can add runtime: shiny to the YAML metadata at the top of the Rmd file to turn it into a Shiny document. I have done this and it works. If I click ""Run Document"" in RStudio it will run the Rmd and I will see the report with no problems. My project is located in the ShinyApps directory where the Shiny Server is looking for apps to serve. When I hit the URL for this project I get the report without any charts . I just get broken image icons where the charts should be. (I am using RStudio Server so it is the exact same files being accessed by RStudio and Shiny Server). R version 3.4.3, Shiny Server version 1.5.6.875 UPDATE: I have reproduced the behaviour with the simplest possible example. I created a new RStudio project - just a plain project - called TEST located in my ShinyApps directory. Then I created a new R Markdown file, which I called TEST.Rmd. This file is pre-populated with example RMarkdown using the cars and pressure built-in datasets. I changed the YAML header to include runtime: shiny . The RStudio ""knit"" button is replaced by the ""Run Document"" button, as expected, and clicking this runs the document and works as expected. Attempting to view the page via the Shiny Server has the same issue whereby the plot is not included; a broken image icon takes its place. UPDATE 2: As requested, here is the Markdown file. It is literally the sample file generated by RStudio with the addition of runtime: shiny in the YAML header. --- title: ""Test RMarkdown"" author: ""Michael Henry"" date: ""4/6/2020"" output: html_document runtime: shiny --- [CODE_BLOCK] ## R Markdown This is an R Markdown document.

You can embed an R code chunk like this: [CODE_BLOCK] ## Including Plots You can also embed plots, for example: [CODE_BLOCK] Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.

I will report back after this has been applied as to whether it resolved my issue. UPDATE 4: It turns out my RHEL server is up-to-date; it already has the version of glib2 suggested by the bugfix.

45744883,Wait functionality in Wget not working as expected,"Background: I am using wget (version 1.14-15.el7) on RedHat Linux (version 7.3 (Maipo)), in a Bash (version 4.2.46(1)) terminal. Unfortunately, I am limited to this particular RHEL image, so I can't upgrade to a newer version of wget. Goal: I am trying to configure wget so that, if a download attempt fails, it does the following: 1) Retries the download 4 more times (total of 5 attempts) 2) Waits a FIXED amount of time (30 seconds) between download attempts ('retries') For context, here is a relevant snippet of the wget manual: -w seconds --wait=seconds Wait the specified number of seconds between the retrievals. Use of this option is recommended, as it lightens the server load by making the requests less frequent. Instead of in seconds, the time can be specified in minutes using the ""m"" suffix, in hours using ""h"" suffix, or in days using ""d"" suffix. Specifying a large value for this option is useful if the network or the destination host is down, so that Wget can wait long enough to reasonably expect the network error to be fixed before the retry. The waiting interval specified by this function is influenced by ""--random-wait"", which see. --waitretry=seconds If you don't want Wget to wait between every retrieval, but only between retries of failed downloads, you can use this option. Wget will use linear backoff, waiting 1 second after the first failure on a given file, then waiting 2 seconds after the second failure on that file, up to the maximum number of seconds you specify. By default, Wget will assume a value of 10 seconds. To be clear, I am using the --wait flag, NOT the --waitretry flag. Process: First, I export/set a wrong http_proxy and https_proxy, to ensure any download attempt will time out. I run the following command: wget --tries=5 --wait=30 <url> -O <output_filename> At this point, the --wait functionality does NOT work as expected. Specifically, it does NOT wait 30s after each download attempt. Instead: 1) After the first attempt, it waits 1s. 2) After the 2nd attempt, it waits 2s. 3) After the 3rd attempt, it waits 3s. and so on ... In other words, despite using the --wait flag (which should result in a fixed waiting time between download attempts), wget seems to be performing a 'linear backoff' as described in the --waitretry flag section. PROBLEM: I want the functionality of the --wait flag, NOT the --waitretry flag. Unfortunately, the --wait flag seems to be acting like the --waitretry flag -- is there any way to get around this apparent bug in wget, so that using the --wait flag results in the expected fixed waiting time between download attempts?","Wait functionality in Wget not working as expected Background: I am using wget (version 1.14-15.el7) on RedHat Linux (version 7.3 (Maipo)), in a Bash (version 4.2.46(1)) terminal.

8683724,Slow initial timing results using gettimeofday - worse under RHEL6 Server,"I am using gettimeofday() to time a simple matrix multiply example, but I'm getting results that are close to twice too long initially. On a RHEL6 Server machine, I'm getting ""bad"" timing results for up to nearly 1 second (~65 individual timings in this example). All our other machines are RHEL5 Workstation boxes and this code works much better on them; I only get a couple of ""bad"" results initially (for first ~20 milliseconds). From posts on this site, I think this probably has something to do with the OS process scheduler. If I uncomment the first ""for"" statement below (thereby inserting an initial busy loop by repeatedly initializing the matrices a, b and c), I get zero ""bad"" results under both RHEL5 Workstation and RHEL6 Server. Alternatively, if I uncomment the sleep statement, I get ALL ""bad"" timing results for both RHEL5 & RHEL6. For some reason, my process is starting up with only about half the access to the CPU initially, then it gets ""full"" access to the CPU as long as the process stays busy. If it ""sleeps"" and then resumes timing, it again is temporarily only getting about half the full access to the CPU. Nothing else is happening on the machine (X is not running). I have tried ""chrt"" to control the priority of the process, but that changed nothing. I've verified this occurs with both GCC 4.4.6 and ICC 12.1.0. I've tried ""nice"" as well.

An example of a hostPath volume specification is shown below, which is taken from the docs. I am deploying to hosts that are running RHEL 7 with SELinux enabled. apiVersion: v1 kind: Pod metadata: name: test-pd spec: containers: - image: k8s.gcr.io/test-webserver name: test-container volumeMounts: - mountPath: /test-pd name: test-volume volumes: - name: test-volume hostPath: # directory location on host path: /data # this field is optional type: Directory When my Pod tries to read from a file that has been mounted from the underlying host, I get a ""Permission Denied"" error. When I run setenforce 0 to turn off SELinux, the error goes away and I can access the file. I get the same error when I bind mount a directory into a Docker container. The issue is described here and, when using Docker, can be fixed by using the z or Z bind mount flag, described in the Docker docs here . Whilst I can fix the issue by running chcon -Rt svirt_sandbox_file_t /path/to/my/host/dir/to/mount I see this as a nasty hack, as I need to do this on every host in my Kubernetes cluster and also because my deployment of Kubernetes as described in the YAML spec is not a complete description of what it is that needs to be done to get my YAML to run correctly.

68662267,&#39;docker stop&#39; impact on established tcp connection,"I'm running 2 docker containers(TcpServer,TcpClient). In each container, there's an init.sh script which launches the applications. In the init.sh script, I've handled SIGTERM but I'm not doing any sort of handling for that(I'm not passing it to my application). trap 'true' SIGTERM After startup, a tcp connection is established between TcpServer and TcpClient. TcpClient is a multi-threaded application, with 1 thread(receiver) doing: while(true) { //blocking tcp receive function call //process received data or received error code. } So basically, the idea is that the receiver thread would always get to know about server going down 'cleanly'. The observation is that, most of the times, when I issue 'docker stop serverContainer', the client application receives TCP 'FIN' packet after about 10 seconds. This is as per my expectations because docker first tries to kill via SIGTERM but since that is handled it then issues SIGKILL which it does only after about 10 seconds. My current understanding is that, whenever sigkill/unhandled-sigterm is given to a process, the kernel will terminate that process and close all file descriptors opened by that process. If this is true, then I should always see a FIN packet going from server to client as soon as the process is killed. However, a few times, FIN packet is not observed in the traces captured on both client and server end. As a result, the client doesn't get to know about the server getting down for a longer time(until it tries to send some data on that connection or the TCP's keepalive mechanism kicks in). I'm not sure how this happens because if I explicitly issue SIGKILL to pid 1 of my server's container(from outside), then I've always seen the FIN packet. So why sometimes, and only when using docker stop, does server not send TCP FIN? Basically I want to ask 2 things: In Linux, when SIGKILL is issued to a TCP server process, is it guaranteed that the kernel/tcp stack will send TCP FIN packet to client before terminating? When I use 'docker stop' how exactly are the processes spawned by the main process(PID 1 inside container) terminated? Because from what I had read, the SIGTERM/SIGKILL is given only to PID 1? So why are its child processes not adopted by init/systemd as happens otherwise(killing the parent process created outside the container).

The code that creates and prints different contour plots is working for whichever of the three plots is created first. It looks like this: Unfortunately the next two plots look like this: The three figures are plotted independently in separate functions and I use clf(""reset""); before and after creating each figure. Each function works in and of itself, but when all three are plotted the second and third figures are all messed up. Has anyone else had this problem?

1837145,PCI Compliance + Magento + PHP version,"I'm trying to get PCI Compliance for my dedicated server (Red Hat Enterprise Linux), which is running Magento. When I first installed Magento on the server, I realized that RHEL comes with a PHP version which is too old for Magento (5.1.6). So, I found a separate repo with PHP version 5.2.11, which got everything running fine, but now I'm in a bind. My PCI Compliance test says that since my PHP version is < 5.3.1 it has security issues. If I try to update to 5.3.1, Magento breaks. I don't want to edit the Magento core to fix those problems, so I guess what I need is a repo with PHP 5.2.11, but that I can confidently say/prove has back-ported to patch up the issues that the PCI Compliance scan identifies. I realize this is terribly convoluted, but if you have any suggestions/tips I'd be happy to hear them.

36474619,Cassandra Nodes Going Down,"I have a 3 node Cassandra cluster setup (replication set to 2) with Solr installed, each node having RHEL, 32 GB Ram, 1 TB HDD and DSE 4.8.3.

I have to do a restart of every node and then they function quite well till the next 3-4 days and again the same problem repeats. I checked the server logs but they do not show any error even when the server goes down. I am unable to figure out why is this happening. In my application, sometimes when I connect to the nodes through the C# Cassandra driver, I get the following error Cassandra.NoHostAvailableException: None of the hosts tried for query are available (tried: 'node-ip':9042) at Cassandra.Tasks.TaskHelper.WaitToComplete(Task task, Int32 timeout) at Cassandra.Tasks.TaskHelper.WaitToComplete[T](Task`1 task, Int32 timeout) at Cassandra.ControlConnection.Init() at Cassandra.Cluster.Init() But when I check the OpsCenter, none of the nodes are down.

57736285,Issues connecting to server with sslv3 disabled in legacy perl,"As the title says, I'm attempting to POST some JSON to a REST API using a pretty old version of perl, specifically 5.10.1. I'm working in a pretty old legacy codebase on RHEL 6. The handshake fails with error 500 because the server has sslv3 disabled. However I'm using versions of LWP and IO::Socket::SSL that I believe nominally support at least TLSv1, which the server supports so I'm unsure why the connection fails as it should just use an acceptable cipher. The server appears to be behind a cloudfront reverse proxy which may be relevant. I don't know enough about SSL to say for certain, but it appears that the issue is in the way the server I care about is set up and how the version of perl and libraries in use implement the cipher. Using an online tool I noticed that the handshake fails on several browsers that do not support SNI. The version of openssl available should support this, but neither of the perl SSL implementations appear to. Is there a way around this? this question seems to be dealing with a similar issue, but they solve it by installing a newer version of perl, which I'm not sure I can do given that this would likely break large portions of the codebase. This unresolved bug seems to accidentally document this behavior my problem is identical to the one listed, but I can also connect to the openssl host.

As libpcap requires superuser privileges to perform this task, I have to somehow give the non-privileged user executing this app the capacity of accessing the NIFs. The maintainer of pcap4j suggests granting capabilities CAP_NET_RAW and CAP_NET_ADMIN to the java command as follow: setcap cap_net_raw,cap_net_admin=eip /path/to/java Due to implementation limitations I am constrained as follow: Avoid giving sudo access to the non-privileged user due to security policies. The same reasoning could be applied to granting above mentioned capabilities to the java command (do not know if capability grantings are given per user/command pair), but, from my relatively scarce knowledge about security, the latter option looks like a more delimited permission granting method for what I want to achieve (solutions are welcome too should an alternative permission granting method looks more suitable for my purpose), and given that the pcapj4 developer, a likely more experienced professional, advices so, I have followed the capability granting path. User must be able to execute the app without being password-prompted Permission granting must be done only once, e.g. when creating the user for the first time.

If I create a new file in a GUI editor such as Coda for Mac, the permissions on the file are 644. If I use that same Coda software and open up the ssh shell built in and touch a new file with the same account the permissions again are the correct 664. Am I missing something with how to correctly configure umask for all types of users regardless of how the file is being created? (interactive or not?) Edit: I got this fixed by finally realizing the files in the GUI were being created locally on the computer and then transferred with the bad permissions.

It should also be noted that I am running without gnome-panel, so it's a completely bare Linux desktop (no menu bar, no task bar). Things behave normally when my JFrame is decorated. That is, pop ups open on top of it and windows no longer disappear behind it when I move my mouse cursor to the second monitor. It's only when I set the JFrame to be undecorated and full screen that windows start getting lost behind it. It's like Linux is ""locking"" the undecorated JFrame to the monitor. I can't alt-drag it in this state either. If I set the JFrame to be slightly smaller than the monitor resolution (e.g. 1 pixel smaller), then it is no longer ""locked"". I can alt-drag it and windows no longer get lost behind it. Is there any way to prevent windows from getting lost behind the full screen, undecorated JFrame?

35301606,Bash script to fill forms on an opened website,"I'm struggling with this issue for a long time, and haven't found any 'elegant' way to achieve my goal. The idea is quite simple: After loading a webpage in Firefox browser I want to be able to fill the available textboxes with a bash script, and leave it for further editing. Curl and wget are a 'no-go' as both of them fill forms and send data directly to a specified website. I've tried xdotool to go through all of the forms, but after filling every single one of the textboxes there is a slight time delay, that varies, before I'm able to jump to the next one. As you can imagine it is far more efficient for me to monitor for the right moment and fill the whole page by hand, rather than setting the maximum (observed) time to wait for every 'jump'. P.S. I'm aware of the available extensions for Firefox, but I'm not permitted to go this way with my project. The system (which is RHEL6) and browser are not to be modified for this task. External repositories, and all the guidance are more than welcome.","Bash script to fill forms on an opened website I'm struggling with this issue for a long time, and haven't found any 'elegant' way to achieve my goal.

33181637,MATLAB&#39;s quadprog is exteremely slow on my strong local machine vs another remote machine,"I am using MATLAB's quadprog and it runs extremely slow on my local machine. When I run the exact code on a remote machine, it completes within 10 minutes. When I run it on my local machine, it doesn't terminates even after 24 hours (I kill it at some point). While the code runs, the memory usage on my local machine is ~10GB RAM (while my local machine has ~100 GB of free RAM). The usage on the remote machine is 20-30GB RAM . Any idea on what to do to make it run faster on my local machine? Important EDIT 18 Oct. : I executed a smaller scale problem on both machines. On the local machine it takes 1900 sec, on the remote it takes 8 sec, a gain of ~240. Both machine also have multiple multi-core processors. I noticed this time with htop , that the remote machine uses all its processors, whilst the local machine uses only a single processor (although all the others are available). Any idea on how can I make MATLAB use all processors on the local machine? Some side notes: 1: nnz for H, Aeq =~ 10e6, dimensions are approx 11e6 x 11e6 2: quad programming with only equality constraints has a closed form solution (See Boyd ). When I solve it with the closed form solution, it takes ~10 minutes on my local machine vs 5 minutes on the remote machine. While both consume ~20-30GB of memory. Since I would like to add inequality constraints, I would like to be able to run quadprog quickly on my local machine. 3: Below is cat /proc/cpuinfo on my machine vs remote machine (the remote machine is stronger, however the local machine is also strong): A 14 cores vs 4 cores is a gain of ~x3.5 (not taking multi-thread overhead), and AVX vs SSE is max ~x2. So it doesn't explain a gain of 240 that I see. Also, when I use the closed form solution (instead of quadprog), the remote machine has a gain of only x2, vs the local machine. 4: I am sure I am running 64 bit version, because I see that the memory consumption is 10-15GB. 5: The local system runs RHEL, the remote runs ubuntu.

12737044,getimagesize does not work with files that contain latin/special chars PHP RHEL,"We have a set of images, around 2500, that are stored in a local RHEL 6.2 server. We also have a MySQL DB with all the names of these files. The problem is, when we call html2pdf to create the PDF from an HTML generated through PHP, whenever it loads an image with special chars, such as áéíóúÁÉÍÓÚñÑ, the script throws an error because the file can't be read (because of the special chars, not because of permissions). so the question is: MySQL returns natively the filename as ""imágen 1 00023884 otoño.jpg"", and the files are stored in RHEL with the same name. How do you tell getimagesize() that it should read the filename AS IS ? I've tried fopen but it doesn't work either, even if I rawurlencode the filename it throws the can't load file error. (""allow_url_fopen"" is on) Everything else works fine with files with no special chars. Hope I made myself clear.

I will attempt to provide as much information as possible here. Versions: RHEL 6.7 | OpenSSL 1.0.1e-fips 11 Feb 2013 Caveats/constraints on the script: this script will be utilized to create multiple key sets - by default, one root keypair and cert and two client keypairs and certs per run. User input is asked for for file location, filename and passphrase on the client keys. All this was fairly straightforward, and I had a script that would run these commands on user request, and utilized the openssl.cnf file to point back to the root key to sign. I had used sed to change the location pointers in openssl.cnf based on filename originally, and was successfully able to sign the client cert. However, there are two major caveats to this: I was asked to change the script so that it is not dynamically the script or other files per each run, meaning openssl.cnf should not be edited on the fly if possinble. If this is needed to function however, then it should be fine. The user needs to be able to run multiple sets of this script ad hoc, especially with regards to the client keypairs (I have the root script and the client generation script separate in a user selectable menu). That is to say, generating the client keypair is requisite on having a root key to associate with, but can be done multiple times, and the client key script should ask the user with which root key to associate and sign from? Because of these constraints, it didn't seem that editing openssl.cnf was a prudent option, and not very scalable. So, given this info my question which I've been unable to figure out is simply: Is there a way to point a client key to a variable which would be the root key cert to sign?

22120207,Portable packaging technology,"I am looking for a good portable technology that would allow for unified way to package software that runs on five different platforms. The platforms are Solaris10/SPARC, Solaris10/X86, Solaris11/SPARC, Solaris11/X86, and RHEL6.4/X86. About 95% of the software is portable Java applications but there a small amount of middleware that is platform-specific. Instead of building five different distributable images that are 95% identical (one for every platform), I want to produce a single universal image for all five. If I follow this route, it makes sense to unify the packaging format to have identical look and feel to the installation process and to keep everything neatly arranged in the distributable image. Oh, and different software components in the image are individual packages, much like a distro comprised of a bunch of RPMs. In a search for a portable packaging mechanism I looked at RPM, which is a pain to build for Solaris (and I need four different builds). I also read up on dpkg and a few other exotic packaging and installation suites. None of them seems to be as portable as I would like it to be. I wish there was a Python version of RPM that does not require anything but Python interpreter, but I could not find anything of this kind. I would really appreciate any hints as to what existing freeware and portable packaging and installation solutions there are. I can always design and build my own but I would rather rely on somebody else who went this route before me.

If so, please, tell me what is the correct way to require a proper Node.js version in my case? Update: I've figured out the problem with Node.js 10 being installed when I required 16.

33281806,Upgraded OpenSSL - How do I get Apache HTTPD to Use?,"I recently had a need to upgrade an old server. The server fulfills a very specific purpose and as such has not been kept up to date. With the recent push for SSL to utilize SHA256 I needed to upgrade a few packages. Short Background The server is RHEL3 (yes, that is correct). I downloaded and built OpenSSL 0.9.8q and ensured it was the only instance of OpenSSL on the server (moving the old instance to a backup directory). I then downloaded and built cURL 7.15.5 with the ./configure --with-ssl=/usr/local/ssl - pointing the with-ssl to my new OpenSSL directory. Once cURL was built I tested my connection to the resource that is requiring sha256 using cURL. My connection test was successful using cURL. On to my problem and question I downloaded httpd 2.0.59 and built it with --enable-ssl and --enable-so , but my tests did not work. I also tried to d/l & build httpd 2.0.63 but I was having trouble getting 2.0.63 working at all. I then took the mod_ssl built from 2.0.63 and put it into the 2.0.59 directory...no luck either. I feel I am missing some element that connects httpd to my newly installed OpenSSL. What do I need to do to ensure mod_ssl is using my new version of OpenSSL on the server? I understand I am quite a few releases behind with my httpd instances, but again, this is an old server with a specific purpose. My only goal is to get it working with sha256, not buy a new server with the latest RHEL, etc. Thank for any input/assistance.","Upgraded OpenSSL - How do I get Apache HTTPD to Use?

12825978,Django syncdb behaving strangely with unicode strings,"I'm going to apologize ahead of time for the length of this post. I just want to be sure I didn't leave any info out. I have an application which uses django's ORM outside of a django app, which uses ""syncdb"" by calling call_command('syncdb') directly (note: I'm using a virtualenv for every scenario listed below). My unit tests in the application try to setup a ""test"" django database using SQLite as the backend (whereas the production environment uses MySQL). Each time one of the unit tests runs, it calls call_command('syncdb') using the same test django settings throughout each test. I am able to run these unit tests on 2 different environments (one with Windows 7/Python 2.7.3, another with Mac OS X ML/Python 2.7.2). There are no issues at all with the tests; but these are relatively clean Python installs on both. However, when I try to run this on a RHEL server, I get the following error, when the unit tests try to run syncdb: DatabaseError: table ""my_app_mytable"" already exists After a lot of frustrating googling and debugging, I (think) I've eliminated the bugs reported here and here . I did a lot of hacking around, and I think I have narrowed the problem down to this statement in django's syncdb command file (as crazy as that sounds) (line 59): tables = connection.introspection.table_names() I setup a pdb.set_trace() inside django's syncdb source on both environments to take a look. Here is what I found: (Env that works) (Pdb) tables [u'my_app_mytable', u'my_app_myothertable'] Seems OK there. From the looks of the syncdb file, django uses the tables variable to check an app's models against what's already in the database. (Env that doesn't work) (Pdb) tables [u'm\x00y\x00_\x00a\x00p\x00p\x00_\x00m\x00y\x00t\x00a\x00', u'm\x00y\x00_\x00a\x00p\x00p\x00_\x00m\x00y\x00o\x00t\x00'] Unless I'm just going crazy, I think this is making the following statement in django's source return false: def model_installed(model): opts = model._meta converter = connection.introspection.table_name_converter return not ((converter(opts.db_table) in tables) or (opts.auto_created and converter(opts.auto_created._meta.db_table) in tables)) This method is called via filter a few lines after that definition, and it looks like it checks to see if converter(opts.db_table) is in the tables list. I ran them manually in both environments too: (Env that works) (Pdb) opts = all_models[0][1][0]._meta (Pdb) converter = connection.introspection.table_name_converter (Pdb) converter(opts.db_table) in tables True As you can see I (kind of) manually ran the model_installed function to see what converter(opts.db_table) returns, and it looks like a perfectly normal string on both environments.

I just want to be sure I didn't leave any info out. I have an application which uses django's ORM outside of a django app, which uses ""syncdb"" by calling call_command('syncdb') directly (note: I'm using a virtualenv for every scenario listed below). My unit tests in the application try to setup a ""test"" django database using SQLite as the backend (whereas the production environment uses MySQL). Each time one of the unit tests runs, it calls call_command('syncdb') using the same test django settings throughout each test. I am able to run these unit tests on 2 different environments (one with Windows 7/Python 2.7.3, another with Mac OS X ML/Python 2.7.2). There are no issues at all with the tests; but these are relatively clean Python installs on both. However, when I try to run this on a RHEL server, I get the following error, when the unit tests try to run syncdb: DatabaseError: table ""my_app_mytable"" already exists After a lot of frustrating googling and debugging, I (think) I've eliminated the bugs reported here and here . I did a lot of hacking around, and I think I have narrowed the problem down to this statement in django's syncdb command file (as crazy as that sounds) (line 59): tables = connection.introspection.table_names() I setup a pdb.set_trace() inside django's syncdb source on both environments to take a look. Here is what I found: (Env that works) (Pdb) tables [u'my_app_mytable', u'my_app_myothertable'] Seems OK there. From the looks of the syncdb file, django uses the tables variable to check an app's models against what's already in the database. (Env that doesn't work) (Pdb) tables [u'm\x00y\x00_\x00a\x00p\x00p\x00_\x00m\x00y\x00t\x00a\x00', u'm\x00y\x00_\x00a\x00p\x00p\x00_\x00m\x00y\x00o\x00t\x00'] Unless I'm just going crazy, I think this is making the following statement in django's source return false: def model_installed(model): opts = model._meta converter = connection.introspection.table_name_converter return not ((converter(opts.db_table) in tables) or (opts.auto_created and converter(opts.auto_created._meta.db_table) in tables)) This method is called via filter a few lines after that definition, and it looks like it checks to see if converter(opts.db_table) is in the tables list. I ran them manually in both environments too: (Env that works) (Pdb) opts = all_models[0][1][0]._meta (Pdb) converter = connection.introspection.table_name_converter (Pdb) converter(opts.db_table) in tables True As you can see I (kind of) manually ran the model_installed function to see what converter(opts.db_table) returns, and it looks like a perfectly normal string on both environments. However: (Env that doesn't work) (Pdb) opts = all_models[0][1][0]._meta (Pdb) converter = connection.introspection.table_name_converter (Pdb) converter(opts.db_table) in tables False So it looks like since the tables variable is a list of crazy-looking crud on the broken environment, that method is falsely claiming that each model's table name isn't in the database, which gives me the original error I stated at the beginning.

72615853,Script to extract switchport status via snmp,"Good day, looking for some assistance, still quite new to scripting and don't have a clue where to start with this. Scenario: I have multiple Cisco switches on which I want to check the port status and alias and only output certain information from the output. So for example I would run snmpwalk -v 2c -c mycommunity myswitchname .1.3.6.1.2.1.2.2.1.8 and will get a list of all ports with their status and then snmpwalk -v 2c -c mycommunity myswitchname .1.3.6.1.2.1.31.1.1.1.18 will give me a list of the interface alias's.

Has anyone else encountered a similar problem to this? Based on some really old threads on House of Fusion (circa 2003) this was a problem that occasionally surfaced due to a caching problem. But, supposedly, that has been fixed in subsequent CF versions.

1862256,Running external code in a restricted environment (linux),"For reasons beyond the scope of this post, I want to run external (user submitted) code similar to the computer language benchmark game . Obviously this needs to be done in a restricted environment. Here are my restriction requirements: Can only read/write to current working directory (will be large tempdir) No external access (internet, etc) Anything else I probably don't care about (e.g., processor/memory usage, etc). I myself have several restrictions. A solution which uses standard *nix functionality (specifically RHEL 5.x) would be preferred, as then I could use our cluster for the backend. It is also difficult to get software installed there, so something in the base distribution would be optimal. Now, the questions: Can this even be done with externally compiled binaries? It seems like it could be possible, but also like it could just be hopeless. What about if we force the code itself to be submitted, and compile it ourselves. Does that make the problem easier or harder? Should I just give up on home directory protection, and use a VM/rollback? What about blocking external communication (isn't the VM usually talked to over a bridged LAN connection?) Something I missed? Possibly useful ideas: rssh . Doesn't help with compiled code though Using a VM with rollback after code finishes (can network be configured so there is a local bridge but no WAN bridge?).

78764164,Does the UBI 8 image not support OpenSSL versions beyond 1.1.1k?,"I have a critical component that relies on OpenSSL version 1.1.1n with custom patches and fixes. Previously, this component was running on a Debian image, but now we are transitioning to UBI8. Despite attempting upgrades and using the latest UBI8.10 version, OpenSSL remains at version 1.1.1k, which is the default supported version in UBI8. Is there a specific reason why I cannot upgrade? Am I overlooking something, or does UBI8 currently not support versions beyond 1.1.1k? I have tried downloading OpenSSL 1.1.1n directly from the OpenSSL libraries to resolve this issue. However, I also need the openssl-libs package, which is used in UBI8 and cannot be manually downloaded(I guess). The current version provided in UBI8 is only up to version k. So even If I somehow manage with latest version of openssl or 1.1.1n version. I would be still getting the openssl-libs of k version only. I need solutions to either work around this issue and achieve compatibility with OpenSSL version 1.1.1n or newer, or solid reasons why achieving this might not be possible.

Mainly Need to figure out a way that we can get both openssl and openssl-libs packages in ubi8 in minimum 1.1.1n version","Does the UBI 8 image not support OpenSSL versions beyond 1.1.1k? I have a critical component that relies on OpenSSL version 1.1.1n with custom patches and fixes. Previously, this component was running on a Debian image, but now we are transitioning to UBI8. Despite attempting upgrades and using the latest UBI8.10 version, OpenSSL remains at version 1.1.1k, which is the default supported version in UBI8. Is there a specific reason why I cannot upgrade? Am I overlooking something, or does UBI8 currently not support versions beyond 1.1.1k? I have tried downloading OpenSSL 1.1.1n directly from the OpenSSL libraries to resolve this issue. However, I also need the openssl-libs package, which is used in UBI8 and cannot be manually downloaded(I guess). The current version provided in UBI8 is only up to version k. So even If I somehow manage with latest version of openssl or 1.1.1n version. I would be still getting the openssl-libs of k version only.

So, once we do the setup and check the End-to-End connectivity, it works fine. By fine, I mean that the Kafka Consumer, Monitor and Producer container logs have live data, when we do the testing, which I suppose indicates that the Kafka broker node and all other components are working fine.

By deleted, I mean that the containers are built with a restart-always condition, so they are not even in exited state. They just vanish out and we had to do the setup all again. The reason we are raising this issue is that we are not able to pinpoint what exactly is causing the Kafka containers to get deleted when the Kafdrop and Zookeeper are still there and just the Kafka broker container gets deleted.

73990199,Jittery movement of QScrollArea from custom touchscreen driver,"So a few years ago, I wrote a custom touchscreen driver specifically for a particular application which ran on a Scientific Linux 6.4 (CentOS 6 based) OS, which did not have native touch support, but the kernel supported touch events, so I was able to directly read the raw data from the touchscreen in /dev/input/event * and read the event data to generate mouse events with Qt to control the application to mimic a multi-touch touchscreen. More recently, we've finally migrated to RedHat 8.4, but I had to disable the native touch driver, because as far as I know, the native Qt touch events didn't allow the same degree of control over the application that my driver did. Recently during a trial, a technician reported that when using the touchscreen to manipulate one of the application's image display areas, the movement was very ""jittery"". The image display area is simply a QScrollArea with a QImage inside, and hidden scroll bars. The way it works is that on a mouseMoveEvent, it manipulates the scrollbars according to the delta value on the mouse event. void PanArea::mouseMoveEvent(QMouseEvent* e) { SafeStr str; if (m_pw) { if (m_disable_panning == false && e->buttons().testFlag(Qt::RightButton)) { QPoint delta = e->pos() - m_last_pos; horizontalScrollBar()->setValue(horizontalScrollBar()->value() - delta.x()); verticalScrollBar()->setValue(verticalScrollBar()->value() - delta.y()); m_last_pos = e->pos(); emit signalScrollPositionChanged(getScrollPosition()); // This force update has been added because // when fast panning cause black to appear within the image // because some pan widget updates were being skipped. // Performance seems acceptable with this here. m_pw->update(); } else if (...) { // irrelevant code removed to save space } } } This works fine when simply right-click dragging on the scroll area. And then here is the relevant function that dispatches the mouse press and mouse move events from the touchscreen driver: void InputHandler::panStart(TouchPoint* tp, QWidget* widget) { QPoint pos(tp->cx(), tp->cy()); QWidget* target = widget; if (target == NULL) target = QApplication::widgetAt(pos); if (target != NULL) { QPoint local = target->mapFromGlobal(pos); QMouseEvent* press = new QMouseEvent(QEvent::MouseButtonPress, local, pos, Qt::RightButton, Qt::RightButton, Qt::NoModifier); QApplication::postEvent(widget, press); } } void InputHandler::panMove(TouchPoint* tp, QWidget* widget) { QPoint pos(tp->cx(), tp->cy()); QWidget* target = widget; if (target == NULL) target = QApplication::widgetAt(pos); if (target != NULL) { QPoint local = target->mapFromGlobal(pos); QMouseEvent* move = new QMouseEvent(QEvent::MouseMove, local, pos, Qt::NoButton, Qt::RightButton, Qt::NoModifier); QApplication::postEvent(widget, move); } } When I touch and drag on the widget, it DOES move, but it jumps all over the place as if I were rapidly dragging it in random directions.

73535130,Kerberos Authentication Across Multiple Domains and Network Interfaces,"I am trying to figure out how to set up passwordless Kerberos authentication with some unusual requirements. -- The Setup -- There are 2 networks: N1 and N2. There are 2 locations: the first location is where all the workstations are located and only has access to network N1, the second is where all the servers are located which are connected to N1 and N2. All of the workstations are windows machine, use the domain *.example.com, and are managed via a windows domain server. All of the servers are RHEL machines and have two domain names: *.a.example.com [the server's address on network N1] and *.b.example.com [the server's address on network N2]. -- The Need -- I need a user to be able to ssh into a server over network N1, this can be done via password or Kerberos. From that server, the user needs to be able to passwordless ssh into all the other servers using either of the server's domain names. -- What I've Tried -- A lot, I've been trying to make this work for 3-4 weeks now but I'll go over where I'm currently at as it seems to be the closest. I have set up 2 child domain servers for a.example.com and b.example.com I have added the servers to both domain controllers and their DNS servers I have used realmd to join the servers to the a.example.com domain server Updated my krb5.conf file to include all the domains (I'll include my configs at the bottom).

71704297,How to securely host file on RHEL server and enable download for user,"I have programmed an application that users can use to process genome data.

At the moment, I have stored this file on Google Drive, but the download bandwith is limited, so if a number of users download the file on a certain day, it will not work for others and they will get errors running the application. My solution would be to host the file on our research server, create a user that only has access rights to this folder and nothing else, and make the file downloadable from the server via scp within the application (which is open source) through that user.

My solution would be to host the file on our research server, create a user that only has access rights to this folder and nothing else, and make the file downloadable from the server via scp within the application (which is open source) through that user. My question now is, is this safe to do or are people potentially able to hack into our server? If this method would be a security risk, what would be a better way to provide this file?

[/opt/app-root/<project_csproj>] About now I think I've gone through all of the search results and none of the answers has helped so far - so maybe here I'll get lucky (and hopefully help someone in the process). Technical data: Jenkins agent Running on RHEL 8.4 with Podman v. 3.2.3 Container data OS - RHEL7.9 and RHEL8.4 (I tried both) Is run with a mounted volume from the Jenkins agent (the directory with the source code from cloned from the repository). Basic Dockerfile setup where I use a RHEL8 base image from our internal repository - the RHEL7 is a modified by installing scl-utils and such but the general idea is the same ARG rhel_version=7.9 ARG build_version=1.0.0 FROM <baseRHELimage> ENV HOME=/opt/app-root/ \ DOTNET_APP_PATH=/opt/app-root/ #DOTNET_RUNNING_IN_CONTAINER=true # Don't download/extract docs for nuget packages ENV NUGET_XMLDOC_MODE=skip RUN <setup yum repos> dnf install -y dotnet-sdk-3.1 &&\ dnf update -y; dnf clean all .NET data Using dotnet core 3.1 SDK The issues occur when I try to run a dotnet build. The Jenkinsfile is firstly removing all bin/ and obj/ directories in the first stage and then invoking the build for the application. The most promising things I tried: Some people suggested that the folders bin/ and obj/ needed to be fully deleted - this is happening in the first stage prior to the run I tried splitting up the dotnet publish command into: dotnet restore dotnet build --no-restore dotnet publish --no-build ... keeps throwing one of those 3 errors randomly across builds directly withing dotnet build I tried invoking that dotnet build with different flags like 'no-parallel' thinking maybe threads are somehow the root cause (I am getting a lot of 'process cannot access the file because it is being used by another process' warnings - but these happen for the successful builds as well - the default dotnet retries seem to be handling those Anyone any idea what I might be missing? The CI/CD pipeline was running previously on a RHEL7.7 agent directly (no containers used). Now we want to move to containerized builds with newer versions of RedHat - but these randomly reoccuring issues are blocking me so if anyone has any suggestions - greatly appreciated ;)",".net, .net-core, containers, rhel, dotnet-build",1,1338,0,https://stackoverflow.com/questions/69455480/dotnet-build-failing-inside-container

Any idea why my RAW socket packets are not correctly processed by the target?","python, windows-xp, wireshark, rhel, raw-sockets",1,737,1,https://stackoverflow.com/questions/51422768/python-raw-socket-frames-never-received

I'm using a centOS7 system. To get information about lvm, an API is defined ( [URL] ). The example program in c++ works perfectly ( [URL] ) with the API linked above. But i'm having trouble, using pinvoke for the API calls from my c# program. I have managed to get version data.

13304416,Curl and Browser are serving different versions of file,I have a wsdl(essentially an xml) file on the server. Now when i access this file from the browser I get the latest version however when i use curl or wget to get this file i get a version which is older. Another interesting thing which happens is that even on deleting the file the curl is still able to get the file but the browser correctly gets a 404. I am not sure why this is happening when the protocol to get the file in both the cases is http and i see the request coming correctly in the apache access logs. However the file being served in both the cases are different. I am using apache webserver on a RHEL machine.

According to what I understood, if my package name is XXX, than I need to prepare rpmbuild/SOURCE/XXX.tar.gz, a tarball which contains: 1. A directory named XXX; 2. In it, all the directories and files I'm installing should be ordered as if their paths are relative to the root directory (i.e. /) For instance, if I want to install a file called foo.sh to /tmp/XXXdir/, I need to have rpmbuild/SOURCE/XXX.tar.gz contain XXX/tpm/xxxdir/foo.sh This is what I understood and this is what works when I install my RPM on my RHEL 5.7 machine (i.e. in the example above the file is installaed to /tmp/XXXdir/foo.sh). However, on an RHEL 6.1 machine I get the undesired behaviour of having my files installed to a newly created /XXX directory, and from there I get the same tree structure I wanted for / (i.e. in the example above I get the file at /XXX/tmp/XXXdir/foo.sh).

I've checked it like this readelf -s lib3rdparty.so | egrep ""@GLIBC_2.[6-9]"" to find references to something newer than GLIBC_2.5 which is installed.

I have the information for each package file in a config file like so: ### packages.config ### declare -A package_a=([name]=""utility-blah"" [ver]=""2.4.1"") declare -A package_b=([name]=""tool-bleh"" [ver]=""1.3.9"") # and so on and so forth My various install scripts source this config file to get package information. Each script contains an array of the packages to be installed. I would like to iterate over this array and install the package named. Ideally, the meat of this loop is in some function so I don't have to rewrite it in each script. In Ubuntu 18 with Bash 4.4, I was able to include this function in the config file like so: ### functions.config ### function install_package() { # dereference hashmap variable declare -n package=""$1"" if dpkg --list ${package[name]}; then echo ""${package[name]} is installed"" else dpkg -i $pathToPackages/${package[name]}_${package[ver]}.deb fi } This leaves only the loop for the actual script, which looks like this: ### install.sh ### source packages.config source functions.config declare -a packageList=(""package_a"" ""package_b"" ""package_d"") for package in ${packageList[@]}; do install_package $package done This worked perfectly for me on Bash 4.4. Unfortunately, the declare -n option was added in Bash 4.3, and as I am now targeting Bash 4.2, the nameref solution no longer works. Is there a way I can have this same behavior where the script will dereference the package variable? I've tried using indirection as this post suggests, but I don't think ${!package[name]} works the way I want it to. Is it possible to achieve the same functionality without using declare -n ?","Indirect reference to hashmap in bash without nameref This is the same situation as a question I asked about a year ago , however I am now targeting RHEL7 and Bash 4.2.46.

So I went to Red Hat's download page [URL] which unfortunately requires a login to access, and downloaded the source package libreoffice-6.0.6.1-19.el8.src.rpm . Then I installed the source package with rpm -Uvh as usual and it created files under the SPECS and SOURCES directories in my RPM build directory. Then as usual I went to build it: % cd SPECS % rpmbuild -ba libreoffice.spec error: Failed build dependencies: bsh is needed by libreoffice-1:6.0.6.1-19.el8.x86_64 glm-devel is needed by libreoffice-1:6.0.6.1-19.el8.x86_64 gpgmepp-devel is needed by libreoffice-1:6.0.6.1-19.el8.x86_64 [etc] Not too surprising, I hadn't expected all of the build dependencies to be already present. So I went to install them, starting with bsh : % sudo dnf -y install bsh Updating Subscription Management repositories. Last metadata expiration check: 0:39:20 ago on Fri 28 Feb 2020 09:39:22 AM GMT. No match for argument: bsh Error: Unable to find a match: bsh Now I'm a bit stumped. The package bsh is required to build libreoffice-base , which is a core package, yet bsh is not packaged? I hope there's something obvious I am missing here.

37281173,Different mail from shell script and cron running the script,"I have a perl script that executes a command. I am saving the output of this command to an array and checking the content on the output to mail me a success or a failure message. This works fine when i run the script itself. But when i schedule the script to run as a cronjob i get a failure mail irrespective of the output. I am using all the abs paths in script and know the cron is executing since i see in my logs that the command is executed successfully . Can someone tell me why the difference? One thing to notice is, the command takes about a minute to finish executing and the script is waiting till the command is executed to check the output. So i am seeing a little delay in the mail when i run the script. But in the cron, i get a mail immediately at the run time. I am assuming the cron isn't waiting for the command to execute and check the output. Could that be the case?","Different mail from shell script and cron running the script I have a perl script that executes a command.

13536788,Same piped call to isql works on Solaris but not on RHEL,"Background: I need to port a ksh script from SunOS 5.10 to RHEL 5.8. It makes a call to isql to retrieve some data and, quite contrary to the intended application of final endpoint client utilities such as isql, it parses its out to be used by a variable in the shell script. Please note that I just inherited this and by no means did design such a hack myself. I certainly never would be parsing isql out to assign value to a var in shell -- if the script needed that info, I would use Perl with some API like DBD::DBI that is designed to marshall data between the application and the data store. But I have what I have and must work within the parameters. What is happening is that the following piped input does return data on SunOS but not in RHEL: echo ""SELECT some_field FROM some_table WHERE some_crtra = 'X' \ngo"" | isql -U$USER -P$PASS -D$DB -S$SERVER That output on Solaris being: some_field ------ Y (1 row affected) From that point, the script uses awk to extract just the field value from the above stream but let's ignore that because that's not the problem. Also please note that I am able to get the data executing the piped commands separately, i.e. by going manually into isql and running the SQL. So the SQL or the connection string are not the problem -- it is either how the piping streams data OR isql itself works differently on the different platforms. Can anybody see why there is disparate response to the same input on the two systems? Any idea how I can change the piping to make it work?

76489955,403 Forbidden on rhel 8.4 using httpd userdir on a folder that is not /home,"I'm in the process of configuring our new server on RedHat 8.4 and making userdir work with httpd has been bugging me. I've configured the file /etc/httpd/conf.d/userdir.conf as follows: <IfModule mod_userdir.c> # # UserDir is disabled by default since it can confirm the presence # of a username on the system (depending on home directory # permissions). # UserDir enabled # # To enable requests to /~user/ to serve the user's public_html # directory, remove the ""UserDir disabled"" line above, and uncomment # the following line instead: # UserDir public_html </IfModule> # # Control access to UserDir directories. The following is an example # for a site where these directories are restricted to read-only. # <Directory ""/user/*/public_html""> Options Indexes FollowSymLinks AllowOverride All Require all granted </Directory> I've used /user because we don't use the /home directory and I think that is part of the problem. I read online that SELinux configures the folder with some degree of accessibility and I tried adding the same rule as /home to the /user folder: /user/[^/]+/.+ all files system_u:object_r:user_home_t:s0 I also ran the command setsebool -P httpd_enable_homedirs 1 , but since /user is not the home directory, it did nothing. I also made sure to give access to the full path leading to /public_html and the folders inside. If you have any ideas of things I can do that I haven't done already, I'll be happy to hear about it.

I've configured the file /etc/httpd/conf.d/userdir.conf as follows: <IfModule mod_userdir.c> # # UserDir is disabled by default since it can confirm the presence # of a username on the system (depending on home directory # permissions). # UserDir enabled # # To enable requests to /~user/ to serve the user's public_html # directory, remove the ""UserDir disabled"" line above, and uncomment # the following line instead: # UserDir public_html </IfModule> # # Control access to UserDir directories. The following is an example # for a site where these directories are restricted to read-only. # <Directory ""/user/*/public_html""> Options Indexes FollowSymLinks AllowOverride All Require all granted </Directory> I've used /user because we don't use the /home directory and I think that is part of the problem. I read online that SELinux configures the folder with some degree of accessibility and I tried adding the same rule as /home to the /user folder: /user/[^/]+/.+ all files system_u:object_r:user_home_t:s0 I also ran the command setsebool -P httpd_enable_homedirs 1 , but since /user is not the home directory, it did nothing. I also made sure to give access to the full path leading to /public_html and the folders inside. If you have any ideas of things I can do that I haven't done already, I'll be happy to hear about it.

Sync links Fixing under replicated partitions in kafka [URL] What is a right value for replica.lag.time.max.ms? [URL] [URL] [URL] here are the options that we consider to do ( but only as suggestion not solution ) restart Kafka brokers , each Kafka step by step remove the non in SYNC replica by rm -rf , as example rm -rf TEST_TOPIC_1 , and hope that Kafka will create this replica and as results it will be in SYNC try to use the kafka-reassign-partitions maybe ISR will be in Sync after some time ? increase replica.lag.time.max.ms to higher value as 1 day and restart the brokers The definition of synchronization depends on the topic configuration, but by default, this means that the replica has been or has been fully synchronized with the leader in the last 10 seconds. The settings for this time period are:replica.lag.time.max.ms, and has a server default value, which can be overridden by each topic. What is the ISR? The ISR is simply all the replicas of a partition that are ""in-sync"" with the leader. The definition of ""in-sync"" depends on the topic configuration, but by default, it means that a replica is or has been fully caught up with the leader in the last 10 seconds. The setting for this time period is: replica.lag.time.max.ms and has a server default which can be overridden on a per topic basis. At a minimum the, ISR will consist of the leader replica and any additional follower replicas that are also considered in-sync. Followers replicate data from the leader to themselves by sending Fetch Requests periodically, by default every 500ms. If a follower fails, then it will cease sending fetch requests and after the default, 10 seconds will be removed from the ISR. Likewise, if a follower slows down, perhaps a network related issue or constrained server resources, then as soon as it has been lagging behind the leader for more than 10 seconds it is removed from the ISR. Some other important related parameters to be configured are: min.insync.replicas: Specifies the minimum number of replicas that must acknowledge a write for the write to be considered successful. offsets.retention.check.interval.ms: Frequency at which to check for stale Offsets. offsets.topic.segment.bytes: This should be kept relatively small in order to facilitate faster Log Compaction and Cache Loads. replica.lag.time.max.ms: If the follower has not consumed the Leaders log OR sent fetch requests, for at least this much time, it is removed from the ISR. replica.fetch.wait.max.ms : Max wait time for each fetcher request issued by follower replicas, must be less than the replica.lag.time.max.ms to avoid shrinking of ISR. transaction.max.timeout.ms: In case a client requests a timeout greater than this value, it’s not allowed so as to not stall other consumers. zookeeper.session.timeout.ms: Zookeeper session timeout. zookeeper.sync.time.ms: How far a follower can be behind a Leader, setting this too high can result in an ISR that has potentially many out-of-sync nodes.","Some replica are not in sync when installing scratch Kafka cluster we are installing new Apache Kafka - version 2.7 on Linux machines version RHEL 7.9 total Kafka machines in the cluster are - 5 machines now installation is completed , but we noticed that not all ISR are in Sync I want to share all the reason that maybe explain what cause replica to be not in Sync Slow replica: A follower replica that is consistently not able to catch up with the writes on the leader for a certain period of time.

Sync links Fixing under replicated partitions in kafka [URL] What is a right value for replica.lag.time.max.ms? [URL] [URL] [URL] here are the options that we consider to do ( but only as suggestion not solution ) restart Kafka brokers , each Kafka step by step remove the non in SYNC replica by rm -rf , as example rm -rf TEST_TOPIC_1 , and hope that Kafka will create this replica and as results it will be in SYNC try to use the kafka-reassign-partitions maybe ISR will be in Sync after some time ? increase replica.lag.time.max.ms to higher value as 1 day and restart the brokers The definition of synchronization depends on the topic configuration, but by default, this means that the replica has been or has been fully synchronized with the leader in the last 10 seconds. The settings for this time period are:replica.lag.time.max.ms, and has a server default value, which can be overridden by each topic. What is the ISR? The ISR is simply all the replicas of a partition that are ""in-sync"" with the leader. The definition of ""in-sync"" depends on the topic configuration, but by default, it means that a replica is or has been fully caught up with the leader in the last 10 seconds. The setting for this time period is: replica.lag.time.max.ms and has a server default which can be overridden on a per topic basis. At a minimum the, ISR will consist of the leader replica and any additional follower replicas that are also considered in-sync. Followers replicate data from the leader to themselves by sending Fetch Requests periodically, by default every 500ms. If a follower fails, then it will cease sending fetch requests and after the default, 10 seconds will be removed from the ISR. Likewise, if a follower slows down, perhaps a network related issue or constrained server resources, then as soon as it has been lagging behind the leader for more than 10 seconds it is removed from the ISR. Some other important related parameters to be configured are: min.insync.replicas: Specifies the minimum number of replicas that must acknowledge a write for the write to be considered successful. offsets.retention.check.interval.ms: Frequency at which to check for stale Offsets. offsets.topic.segment.bytes: This should be kept relatively small in order to facilitate faster Log Compaction and Cache Loads. replica.lag.time.max.ms: If the follower has not consumed the Leaders log OR sent fetch requests, for at least this much time, it is removed from the ISR. replica.fetch.wait.max.ms : Max wait time for each fetcher request issued by follower replicas, must be less than the replica.lag.time.max.ms to avoid shrinking of ISR. transaction.max.timeout.ms: In case a client requests a timeout greater than this value, it’s not allowed so as to not stall other consumers. zookeeper.session.timeout.ms: Zookeeper session timeout. zookeeper.sync.time.ms: How far a follower can be behind a Leader, setting this too high can result in an ISR that has potentially many out-of-sync nodes.","apache-kafka, rhel",0,3346,1,https://stackoverflow.com/questions/73021580/some-replica-are-not-in-sync-when-installing-scratch-kafka-cluster

Today I setup AdGuard DNS server in my home lab, on the same machine is a reverse proxy to serve some internal services, I added a second IP to the host because I needed multiple HTTP ports. Nevermind, I set a wildcard DNS entry on adguard. Like this: *.mydomain.com 172.16.20.60 (which is the IP of the reverse proxy mentioned above) - I didn't want to add all services manually, so I chose the wildcard method. A few hours later I noticed that the machine that hosts the dns server and reverse proxy wasn't able to connect to the internet. I did a traceroute and saw that it was trying to reach the internet over _gateway.mydomain.com (which leads to the machine itselfs). A ping on _gateway.mydomain.com returned the machines IP, so I remembered the wildcard dns entry on my dns server. I added _gateway.mydomain.com to it's correct IP and then it worked as expected. My question is what is the thing about this kind of environment variable ""_gateway""/""gateway"" - why does RedHat do this? And I wonder why the network tries to reach it's gateway via a dns name?

35531661,Using env variable in Spring Boot&#39;s application.properties,"We are working on a Spring Boot web application, and the database we are using is MySQL; the setup we have is we first test it locally (means we need to install MySQL on our PC); then we push to Bitbucket; Jenkins automatically detects the new push to Bitbucket and does a build on it (for Jenkins mvn build to pass we also need to install MySQL on the virtual machines that is running Jenkins). if Jenkins build passes we push the code to our application on OpenShift (using the Openshift deployment plugin on Jenkins). The problem we have, as you may have already figured it out, is that: in application.properties we can not hard code the MySQL info. Since our project will be running in 3 different places ( local , Jenkins , and OpenShift ), we need to make the datasource field dynamic in application.properties (we know there are different ways of doing it but we are working on this solution for now). spring.datasource.url = spring.datasource.username = spring.datasource.password = The solution we came up with is we create system environment variables locally and in the Jenkins VM (naming them the same way OpenShift names them), and assigning them the right values respectively: export OPENSHIFT_MYSQL_DB_HOST=""jdbc:mysql://localhost"" export OPENSHIFT_MYSQL_DB_PORT=""3306"" export OPENSHIFT_MYSQL_DB_USERNAME=""root"" export OPENSHIFT_MYSQL_DB_PASSWORD=""123asd"" We have done this and it works.

48423398,What is a good way to deploy secret Java key stores in an OpenShift environment?,"We have a Java web application that is supposed to be moved from a regular deployment model (install on a server) into an OpenShift environment (deployment as docker container). Currently this application consumes a set of Java key stores (.jks files) for client certificates for communicating with third party web interfaces. We have one key store per interface. These jks files get manually deployed on production machines and are occasionally updated when third-party certificates need to be updated. Our application has a setting with a path to the key store files and on startup it will read certificates from them and then use them to communicate with the third-party systems. Now when moving to an OpenShift deployment, we have one docker image with the application that is going to be used for all environments (development, test and production). All configuration is given as environment variables. However we cannot give jks files as environment variables these need to be mounted into the docker container's file system. As these certificates are a secret we don't want to bake them into the image. I scanned the OpenShift documentation for some clues on how to approach this and basically found two options: using Secrets or mounting a persistent volume claim (PVC). Secrets don't seem to work for us as they are pretty much just key-value-pairs that you can mount as a file or have handed in as environment variables. They also have a size limit to them. Using a PVC would theoretically work, however we'd need to have some way to get the JKS files into that volume in the first place. A simple way would be to just start a shell container mounting the PVC and copying the files manually into it using the OpenShift command line tools, however I was hoping for a somewhat less manual solution. Do you have found a clever solution to this or a similar problem where you needed to get files into a container?","What is a good way to deploy secret Java key stores in an OpenShift environment?

54819381,Request vs limit cpu in kubernetes/openshift,"I have some dilemma to choose what should be the right request and limit setting for a pod in Openshift. Some data: during start up, the application requires at least 600 millicores to be able to fulfill the readiness check within 150 seconds. after start up, 200 millicores should be sufficient for the application to stay in idle state. So my understanding from documentation: CPU Requests Each container in a pod can specify the amount of CPU it requests on a node. The scheduler uses CPU requests to find a node with an appropriate fit for a container. The CPU request represents a minimum amount of CPU that your container may consume, but if there is no contention for CPU, it can use all available CPU on the node. If there is CPU contention on the node, CPU requests provide a relative weight across all containers on the system for how much CPU time the container may use. On the node, CPU requests map to Kernel CFS shares to enforce this behavior. Noted that the scheduler will refer to the request CPU to perform allocation on the node, and then it is a guarantee resource once allocated. Also on the other side, I might allocate extra CPU as the 600 millicores might be only required during start up. So should i go for resources: limits: cpu: 1 requests: cpu: 600m for guarantee resource or resources: limits: cpu: 1 requests: cpu: 200m for better cpu saving","Request vs limit cpu in kubernetes/openshift I have some dilemma to choose what should be the right request and limit setting for a pod in Openshift.

Currently, I get this token by executing the following commands with ssh on the machine where OpenShift is installed: oc login --username=<uname> --password=<password> oc whoami --show-token I would like to stop using the oc tool completely and get this token using HTTP calls to the APIs but am not really able to find a document that explains how to use it. If I use the option --loglevel=10 when calling oc commands I can see the HTTP calls made by oc when logging in but it is quite difficult for me to reverse-engineer the process from these logs. Theoretically this is not something specific to OpenShift but rather to the OAuth protocol, I have found some documentation like the one posted here but I still find it difficult to implement without specific examples. If that helps, I am developing this tool using ruby (not rails). P.S. I know that normally for this type of job one should use Service Account Tokens but since this is a testing environment the OpenShift installation gets removed and reinstalled fairly often.

58078775,Openshift service is not available after short inactivity,"We have our project hosted in OpenShift (OKD to be precise. We host it ourselves). The setup is as follows: Routing server (Spring Boot 1.5.8 with Zuul): This one takes all the incoming traffic and routes it to the correct services Multiple services (all with Spring Boot): Here is all the business logic We use SOAP for calling other services in this project. Currently, when we call the application, the call goes to the routing server, which then routes it to the main business service. After a short inactivity of about one hour, our main business service is not reachable via the external call. The edge server however is available and callable 100% of the time. We do get a 504 Gateway Timeout exception from the system when we call it. We already figured out that this is the timeout of the route in openshift ( haproxy.router.openshift.io/timeout in the route). The core problem is, that OpenShift seems to hibernate the main business service after an inactivity of about one hour. After a delay of 15 minutes however the calls seem to find their destination and the data gets processed correctly. How can we turn this behaviour off? Edit 1: We have the same application in normal ""old fashioned"" VMs in production. We don't have any problems there. We noticed that the services can be ""kept alive"" when we call them regulary.

error: ffi.h: No such file or directory on pip2 install pyOpenSSL One of the steps I always use to install / build my Ansible agent on target nodes was pip2 install pyOpenSSL . This is a requirement for your Ansible client in order to use the standard Ansible module for creating self signed certificates for example openssl_certificate Since today this no longer works. I can reproduce this message as follows: vagrant init generic/ubuntu1804 vagrant ssh sudo su - apt-get update && apt-get -y install python python-pip pip2 install pyOpenSSL The last step fails with message below. What is correct way to install pyOpenSSL on Ubuntu 18.04 at the moment? Is there a workaround for this problem? Or beter, is there a Python distribution for Ansible? That includes all dependencies so I don't have to compile build my own Ansible client? root@ubuntu1804:~# pip2 install pyOpenSSL Collecting pyOpenSSL Retrying (Retry(total=4, connect=None, read=None,

Here's my sample code: # Usage: ansible-playbook tst3.yaml --limit <GRP> --- - hosts: all remote_user: root tasks: - name: Create the list set_fact: my_item: ""{{ item }}"" with_items: - ""One fish"" - ""Two fish"" - ""Red fish"" - ""Blue fish"" register: my_item_result - name: Extract items and turn into a list set_fact: my_list: ""{{ my_item_result.results | map(attribute='ansible_facts.my_item') | list }}"" - name: Examine the list debug: msg: ""{{ my_list }}"" - name: Concatenate the public keys set_fact: my_joined_list: ""{{ item | join('\n') }}"" with_items: - ""{{ my_list }}"" - name: Examine the joined string debug: msg: ""{{ my_joined_list }}"" I want to get output that looks like: One fish Two fish Red fish Blue Fish What I get instead is: TASK: [Examine the joined string] ********************************************* ok: [hana-np-11.cisco.com] => { ""msg"": ""B\nl\nu\ne\n \nf\ni\ns\nh"" } ok: [hana-np-12.cisco.com] => { ""msg"": ""B\nl\nu\ne\n \nf\ni\ns\nh"" } ok: [hana-np-13.cisco.com] => { ""msg"": ""B\nl\nu\ne\n \nf\ni\ns\nh"" } ok: [hana-np-14.cisco.com] => { ""msg"": ""B\nl\nu\ne\n \nf\ni\ns\nh"" } ok: [hana-np-15.cisco.com] => { ""msg"": ""B\nl\nu\ne\n \nf\ni\ns\nh"" } How do I properly concatenate a list of strings with the newline character?",ansible,63,150646,2,https://stackoverflow.com/questions/47244834/how-to-join-a-list-of-strings-in-ansible

47877464,How Exactly Does Ansible Parse Boolean Variables?,"In Ansible, there are several places where variables can be defined: in the inventory, in a playbook, in variable files, etc. Can anyone explain the following observations that I have made? When defining a Boolean variable in an inventory, it MUST be capitalized (i.e., True/False), otherwise (i.e., true/false) it will not be interpreted as a Boolean but as a String. In any of the YAML formatted files (playbooks, roles, etc.) both True/False and true/false are interpreted as Booleans. For example, I defined two variables in an inventory: abc=false xyz=False And when debugging the type of these variables inside a role... - debug: msg: ""abc={{ abc | type_debug }} xyz={{ xyz | type_debug }}"" ... then abc becomes unicode but xyz is interpreted as a bool : ok: [localhost] => { ""msg"": ""abc=unicode xyz=bool"" } However, when defining the same variables in a playbook, like this: vars: abc: false xyz: False ... then both variables are recognized as bool . I had to realize this the hard way after executing a playbook on production, running something that should not have run because of a variable set to 'false' instead of 'False' in an inventory. Thus, I'd really like to find a clear answer about how Ansible understands Booleans and how it depends on where/how the variable is defined. Should I simply always use capitalized True/False to be on the safe side? Is it valid to say that booleans in YAML files (with format key: value ) are case-insensitive, while in properties files (with format key=value ) they are case-sensitive? Any deeper insights would be highly appreciated.","How Exactly Does Ansible Parse Boolean Variables?

21670747,What user will Ansible run my commands as?,"Background My question seems simple, but it gets more complex really fast. Basically, I got really tired of maintaining my servers manually (screams in background) and I decided it was time to find a way to make being a server admin much more liveable. That's when I found Ansible. Great huh? Sure beats making bash scripts (louder scream) for everything I wanted to automate. What's the problem? I'm having a lot of trouble figuring out what user my Ansible playbook will run certain things as. I also need the ability to specify what user certain tasks will run as. Here are some specific use cases: Cloning a repo as another user: My purpose with this is it run my node.js webapp from another user, who we'll call bill (that can only use sudo to run a script that I made that starts the node server, as opposed to root or my user that can use sudo for all commands). To do this, I need the ability to have Ansible's git module clone my git repo as bill . How would I do that? Knowing how Ansible will gain root: As far as I understand, you can set what user Ansible will connect to the server you're maintaining by defining 'user' and the beginning of the playbook file. Here's what I don't understand: if I tell it to connect via my username, joe , and ask it to update a package via the apt module, how will it gain root? Sudo usually prompts me for my password, and I'd prefer keeping it that way (for security). Final request I've scoured the Ansible docs, done some (what I thought was thorough) Googling, and generally just tried to figure it out on my own, but this information continues to elude me. I am very new to Ansible, and while it's mostly straight-forwards, I would benefit greatly if I could understand exactly how Ansible runs, on which users it runs, and how/where I can specify what user to use at different times.

So I have written the 2nd playbook as below [root@server thebigone]# cat instance_restart.yaml --- - hosts: instance_1 gather_facts: no tasks: - include: check_java_pid.yaml But while doing ansible-playbook instance_restart.yaml , I am getting below errors ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path. The error appears to have been in '/home/root/ansible/thebigone/check_java_pid.yaml': line 2, column 3, but may be elsewhere in the file depending on the exact syntax problem. The offending line appears to be: --- - hosts: all ^ here The error appears to have been in '/home/root/ansible/thebigone/check_java_pid.yaml': line 2, column 3, but may be elsewhere in the file depending on the exact syntax problem. The offending line appears to be: --- - hosts: all ^ here Its saying syntax error but there isn't one really AFAIK as I have executed Playbook check_java_pid.yaml without any issues.

Template file: oracle_url = {{ data_base_url }} The problem is that the {{ db }} variable in the group_vars/all file is not replaced by the DB host IP. The user can only edit the inventory file.","ansible, ansible-inventory",30,172480,7,https://stackoverflow.com/questions/21908363/ansible-read-inventory-hosts-and-variables-to-group-vars-all-file

47167446,How to set an Ansible variable for all plays/hosts?,"This question is NOT answered. Someone mentioned environment variables. Can you elaborate on this? 5/28/2024 - Simplified the question (below): This is an oracle problem. I have 4 PCs. I need program 1 run on the one machine that has Drive E. Out of the remaining 3 that don't have drive E, I need program 2 run on ONLY one of the 3. For the other 2, don't run anything. This seems like a simple problem, but not in ansible. It keeps coming up. Especially in error conditions. I need a global variable. One that I can set when processing one host play, then check at a later time with another host. In a nutshell, so I can branch later in the playbook, depending on the variable. We have no control over custom software installation, but if it is installed, we have to put different software on other machines. To top it off, the installations vary, depending on the VM folder. My kingdom for a global var. The scope of variables relates ONLY to the current ansible_hostname. Yes, we have group_vars/all.yml as globals, but we can't set them in a play. If I set a variable, no other host's play/task can see it. I understand the scope of variables, but I want to SET a global variable that can be read throughout all playbook plays. The actual implementation is unimportant but variable access is (important). My Question: Is there a way to set a variable that can be checked when running a different task on another host? Something like setGlobalSpaceVar(myvar, true)? I know there isn't any such method, but I'm looking for a work-around. Rephrasing: set a variable in one tasks for one host, then later in another task for another host, read that variable. The only way I can think of is to change a file on the controller, but that seems bogus. An example The following relates to oracle backups and our local executable, but I'm keeping it generic. For below - Yes, I can do a run_once, but that won't answer my question. This variable access problem keeps coming up in different contexts. I have 4 xyz servers. I have 2 programs that need to be executed, but only on 2 different machines. I don't know which. The settings may be change for different VM environments. Our programOne is run on the server that has a drive E. I can find which server has drive E using ansible and do the play accordingly whenever I set a variable (driveE_machine). It only applies to that host. For that, the other 3 machines won't have driveE_machine set. In a later play, I need to execute another program on ONLY one of the other 3 machines. That means I need to set a variable that can be read by the other 2 hosts that didn't run the 2nd program. I'm not sure how to do it.

However, I need to figure out a way to access certain libraries that are not built in R, dplyr..etc. Based on my research seems like there are two approaches: (1) In the reducer code, install the required libraries to a temporary folder and they will be disposed when the session is done, like this: .libPaths(c(.libPaths(), temp <- tempdir())) install.packages(""dplyr"", lib=temp, repos='[URL] library(dplyr) ... However, this approach will have a dramatic overhead depending on how many libraries you are trying to install.

36134552,Use multiple var files in ansible role,"One of my roles has two different variable types. One is public (things like package versions and other benign information). These can be committed to SCM without a worry. It also requires some private information (such as API keys and other secret information). I'm using ansible-vault to encrypt secret information. My solution was to have vars/main.yaml for pulic, and vars/vault.yml for the encrypted private information. I came across a problem and am uncertain what's the best practice or actual solution here. It seems that ansible only loads the vars/main.yml file. Naturally I do not want to encrypt the public information so I looked for solution. So far the only solution I came up with (suggested on IRC) is to create group_vars/all/vault.yml and prefix all variables with the role name. This works because ansible seems to recursively load everything under group_vars . This does work but seems organizationally incorrect because the variables are for a specific role and not ""globally universally true"". I also tried to put include: vars/vault.yml into vars/main.yml but that did not work. Is there a proper way to do this?","Use multiple var files in ansible role One of my roles has two different variable types. One is public (things like package versions and other benign information). These can be committed to SCM without a worry. It also requires some private information (such as API keys and other secret information). I'm using ansible-vault to encrypt secret information. My solution was to have vars/main.yaml for pulic, and vars/vault.yml for the encrypted private information. I came across a problem and am uncertain what's the best practice or actual solution here. It seems that ansible only loads the vars/main.yml file. Naturally I do not want to encrypt the public information so I looked for solution. So far the only solution I came up with (suggested on IRC) is to create group_vars/all/vault.yml and prefix all variables with the role name.

39069311,Terraform: How to run remote-exec more than once?,"I have noticed that terraform will only run ""file"", ""remote-exec"" or ""local-exec"" on resources once. Once a resource is provisioned if the commands in a ""remote-exec"" are changed or a file from the provisioner ""file"" is changed then terraform will not make any changes to the instance. So how to I get terraform to run provisioner ""file"", ""remote-exec"" or ""local-exec"" everytime I run a terraform apply? For more details: Often I have had a resource provisioned partially due to an error from ""remote-exec"" causes terraform to stop (mostly due to me entering in the wrong commands while I'm writing my script). Running terraform again after this will cause the resource previously created to be destroyed and force terraform to create a new resource from scratch. This is also the only way I can run ""remote-exec"" twice on a resource... by creating it over from scratch. This is really a drawback to terraform as opposed to ansible, which can do the same exact job as terraform except that it is totally idempotent. When using Ansible with tasks such as ""ec2"", ""shell"" and ""copy"" I can achieve the same tasks as terraform only each of those tasks will be idempotent. Ansible will automatically recognise when it doesn't need to make changes, where it does and because of this it can pick up where a failed ansible-playbook left off without destroying everything and starting from scratch. Terraform lacks this feature. For reference here is a simple terraform resource block for an ec2 instance that uses both ""remote-exec"" and ""file"" provisioners: resource ""aws_instance"" ""test"" { count = ${var.amt} ami = ""ami-2d39803a"" instance_type = ""t2.micro"" key_name = ""ansible_aws"" tags { name = ""test${count.index}"" } #creates ssh connection to consul servers connection { user = ""ubuntu"" private_key=""${file(""/home/ubuntu/.ssh/id_rsa"")}"" agent = true timeout = ""3m"" } provisioner ""remote-exec"" { inline = [<<EOF sudo apt-get update sudo apt-get install curl unzip echo hi EOF ] } #copying a file over provisioner ""file"" { source = ""scripts/test.txt"" destination = ""/path/to/file/test.txt"" } }","Terraform: How to run remote-exec more than once?

In the interests of simplicity I’ve reproduced it using this basic playbook for a single node Drupal server. [URL] ; this playbook works fine on earlier versions of ubuntu, but not on 18.04 which I understand includes python3 by default. I’ve used vagrant to create the base machine, which shows the following: $ which python /usr/bin/python $ which python2 /usr/bin/python2 $ which python3 /usr/bin/python3 $ python --version Python 2.7.15rc1 $ python2 --version Python 2.7.15rc1 $ python3 --version Python 3.6.7 Which seems to be telling me that both python 2 and python 3 are installed, but that 2.7 is the default as that is what responds to $ python --version. I have tried all the suggestions described in this article: [URL] Including specifying the ansible_python_interpreter=/usr/bin/python3 But nothing affects the message. The edited -vvv output from the playbook run is below. Has anyone got any more ideas about either the problem or solution.

37499514,How Docker and Ansible fit together to implement Continuous Delivery/Continuous Deployment,"I'm new to the configuration management and deployment tools. I have to implement a Continuous Delivery/Continuous Deployment tool for one of the most interesting projects I've ever put my hands on. First of all, individually, I'm comfortable with AWS , I know what Ansible is, the logic behind it and its purpose. I do not have same level of understanding of Docker but I got the idea. I went through a lot of Internet resources, but I can't get the the big picture. What I've been struggling is how they fit together. Using Ansible , I can manage my Infrastructure as Code; building EC2 instances, installing packages... I can even deploy a full application by pulling its code, modify config files and start web server. Docker is, itself, a tool that packages an application and ensures that it can be run wherever you deploy it. My problems are: How does Docker (or Ansible and Docker) extend the Continuous Integration process!? Suppose we have a source code repository, the team members finish working on a feature and they push their work. Jenkins detects this, runs all the acceptance/unit/integration test suites and if they all passed, it declares it as a stable build. How Docker fits here? I mean when the team pushes their work, does Jenkins have to pull the Docker file source coded within the app, build the image of the application, start the container and run all the tests against it or it runs the tests the classic way and if all is good then it builds the Docker image from the Docker file and saves it in a private place? Should Jenkins tag the final image using x.y.z for example!? Docker containers configuration : Suppose we have an image built by Jenkins stored somewhere, how to handle deploying the same image into different environments, and even, different configurations parameters ( Vhosts config, DB hosts, Queues URLs, S3 endpoints, etc...) What is the most flexible way to deal with this issue without breaking Docker principles? Are these configurations backed in the image when it gets build or when the container based on it is started, if so how are they injected? Ansible and Docker : Ansible provides a Docker module to manage Docker containers. Assuming I solved the problems mentioned above, when I want to deploy a new version x.t.z of my app, I tell Ansible to pull that image from where it was stored on, start the app container, so how to inject the configuration settings!? Does Ansible have to log in the Docker image, before it's running ( this sounds insane to me ) and use its Jinja2 templates the same way with a classic host!? If not, how is this handled?! Excuse me if it was a long question or if I misspelled something, but this is my thinking out loud. I'm blocked for the past two weeks and I can't figure out the correct workflow. I want this to be a reference for future readers. Please, it would very helpful to read your experiences and solutions because this looks like a common workflow.","How Docker and Ansible fit together to implement Continuous Delivery/Continuous Deployment I'm new to the configuration management and deployment tools.

23056177,Continuous deployment &amp; AWS autoscaling using Ansible (+Docker ?),"My organization's website is a Django app running on front end webservers + a few background processing servers in AWS. We're currently using Ansible for both : system configuration (from a bare OS image) frequent manually-triggered code deployments. The same Ansible playbook is able to provision either a local Vagrant dev VM, or a production EC2 instance from scratch. We now want to implement autoscaling in EC2, and that requires some changes towards a ""treat servers as cattle, not pets"" philosophy. The first prerequisite was to move from a statically managed Ansible inventory to a dynamic, EC2 API-based one, done. The next big question is how to deploy in this new world where throwaway instances come up & down in the middle of the night. The options I can think of are : Bake a new fully-deployed AMI for each deploy , create a new AS Launch config and update the AS group with that. Sounds very, very cumbersome, but also very reliable because of the clean slate approach, and will ensure that any system changes the code requires will be here. Also, no additional steps needed on instance bootup, so up & running more quickly. Use a base AMI that doesn't change very often, automatically get the latest app code from git upon bootup, start webserver. Once it's up just do manual deploys as needed, like before. But what if the new code depends on a change in the system config (new package, permissions, etc) ? Looks like you have to start taking care of dependencies between code versions and system/AMI versions, whereas the ""just do a full ansible run"" approach was more integrated and more reliable. Is it more than just a potential headache in practice ? Use Docker ? I have a strong hunch it can be useful, but I'm not sure yet how it would fit our picture. We're a relatively self-contained Django front-end app with just RabbitMQ + memcache as services, which we're never going to run on the same host anyway. So what benefits are there in building a Docker image using Ansible that contains system packages + latest code, rather than having Ansible just do it directly on an EC2 instance ? How do you do it ? Any insights / best practices ? Thanks !","Continuous deployment &amp; AWS autoscaling using Ansible (+Docker ?)

I would love to have the with_items part just be an array of IP addresses, rather than an array of objects with arrays of objects inside them. In Python, I would just do something like: ips = [r['instances'][0]['private_ip'] for r in ec2['results']] And then I would use with_items: '{{ ips }}' in the second task.

71565392,Why is ansible slow with simple tasks,"After using ansible for about a week now, I found out that ansible takes similar amount of time regardless of how complicated is the task it is supposed to do. Install 20 packages using apt - 3 seconds Copy a single file with 2 config settings using template - 3 seconds. While I can easily install 20 packages using just a single command, template needs to be run in a loop, so if I have 20 config files to copy, then it takes a whole minute. Scale that to 10 roles, some of them repeated 5 times and you can get over an hour to do a simple deployment. Is ansible supposed to be this slow, or is there something I can do to improve the performace? edit: Based on your answers I assume this is not a normal behavior.

Install 20 packages using apt - 3 seconds Copy a single file with 2 config settings using template - 3 seconds. While I can easily install 20 packages using just a single command, template needs to be run in a loop, so if I have 20 config files to copy, then it takes a whole minute. Scale that to 10 roles, some of them repeated 5 times and you can get over an hour to do a simple deployment. Is ansible supposed to be this slow, or is there something I can do to improve the performace? edit: Based on your answers I assume this is not a normal behavior.

How to get / install ansible using Cygwin? I tried the following steps but it's didn't work during bullet 5 (while running "" python setup.py install ""). Steps taken from: Taken from [URL] 1) Download and install Cygwin, with at least the following packages selected (you can select the packages during the install process): libyaml libyaml-devel curl python (2.7.x) python-crypto python-openssl python-paramiko python-setuptools git (2.1.x) vim openssh openssl openssl-devel 2) Download and install PyYAML and Jinja2, as they're not available via Cygwin's installer: 1. Open Cygwin 2. Download PyYAML: curl -O [URL] 3. Download Jinja2: curl -O [URL] 4. Untar both downloads: tar -xvf PyYAML-3.10.tar.gz && tar -xvf Jinja2-2.6.tar.gz 5. Change directory into each of the expanded folders and run python ""python setup.py install"" to install each package. 6. Clone ansible from its repository on GitHub: git clone [URL] /opt/ansible This was tested with Ansible version v1.6.6, change directory into /opt/ansible and checkout the correct tag: git checkout v1.6.6. 7. Add the following lines into your Cygwin .bash_profile: # Ansible settings ANSIBLE=/opt/ansible export PATH=$PATH:$ANSIBLE/bin export PYTHONPATH=$ANSIBLE/lib export ANSIBLE_LIBRARY=$ANSIBLE/library 8.

I'm playing with Kubernetes and use Ansible for any interactions with my cluster. Have some playbooks that successfully deploy applications.

I can successfully wait until deployment completes using k8s: state: present definition: config.yaml wait: yes wait_timeout: 10 But, unfortunately, the same trick doesn't work by default with Kubernetes Jobs. The module simply exits immediately that is clearly described in ansible module, that's true: For resource kinds without an implementation, wait returns immediately unless wait_condition is set. To cover such a case, module spec suggests to specify wait_condition: reason: REASON type: TYPE status: STATUS The doc also says: The possible types for a condition are specific to each resource type in Kubernetes. See the API documentation of the status field for a given resource to see possible choices. I checked API specification and found the same as stated in the following answer : the only type values are “Complete” and “Failed”, and that they may have a ”True” or ”False” status So, my QUESTION is simple: is there anyone who know how to use this wait_condition properly?

The data is taken from this question and the playbook is based on this answer . The question(s): Why storing the left part (before json_query ) of the following expression in a variable and then using json_query on the variable causes the expression to be evaluated differently?

42282750,How to store command output into array in Ansible?,"Essentially, I want to be able to handle ""wildcard filenames"" in Linux using ansible. In essence, this means using the ls command with part of a filename followed by an ""*"" so that it will list ONLY certain files. However, I cannot store the output properly in a variable as there will likely be more than one filename returned. Thus, I want to be able to store these results no matter how many there might be in an array during one task. I then want to be able to retrieve all of the results from the array in a later task. Furthermore, since I don't know how many files might be returned, I cannot do a task for each filename, and an array makes more sense. The reason behind this is that there are files in a random storage location that are changed often, but they always have the same first half. It's their second half of their names that are random, and I don't want to have to hard code that into ansible at all. I'm not certain at all how to properly implement/manipulate an array in ansible, so the following code is an example of what I'm ""trying"" to accomplish.

50009948,GAE : How to deploy various environments with secrets?,"I have a staging and a production project on App Engine, with 6 services on each. For the moment, we deploy from the developers computer, using gcloud app deploy app.staging.yaml --project staging-project or gcloud app deploy app.production.yaml --project production-project It works but it causes issues with environment variables, and especially with secrets. Our apps gets their Api keys, database credentials and other things from the environment variables - that allows us to have the exact same app running locally, in a Docker Container or in App Engine without knowing where it is deployed. If I follow the documentation way to deploy, our app.yaml files would look like this: app.production.yaml runtime: nodejs env: flex manual_scaling: instances: 1 env_variables: DATABASE_PASSWORD: ""topsecret"" MY_API_KEY: ""ultrasecret"" I think everybody easily understands why it's a bad idea to store that on a Git repository.

I found out 3 workarounds, and their reason to not be used: Use Google KMS - allows us to put encrypted secrets directly into the project, but it requires us to put custom code in our apps to decrypt them. It creates a different environment management between local, staging and production. It increases the risk of bugs due to the complexity. Store secrets in Google Datastore - I tried it, I created a helper that searches env vars in proccess.ENV, then in cache and ultimately in Datastore. But like KMS, it increases complexity a lot. Store secrets in a JSON file and put in on Google Cloud Storage : again, it requires to load env variables through an helper that checks env vars, then loads the file etc... Ultimately, we are exploring the feasibility to use a deployment server that would be triggered by developers or Continuous Integration and handle all the secrets injection when deploying to App Engine. But these tools like Ansible , Salt, Puppet, Chef only have plugins for Compute Engine and do not support App Engine. +-------------------------+ +-------------------+ +---------------------+ | | | +---> | | Developer workspace | | Ansible | | App Engine STAGING | | +----> (or other) | | | +-------------------------+ | | +---------------------+ | | +-------------------------+ | | +---------------------+ | +----> Injects secrets | | | | Continous Integration | | | App Engine PROD. | | | | +---> | +-------------------------+ +-------------------+ +---------------------+ This leads me to 3 questions: Do you think using a deployment server with App Engine is a good idea ?

For the moment, we have this shadow file that every developer have to fill before deployment app.production.yaml.shadow runtime: nodejs env: flex manual_scaling: instances: 1 env_variables: DATABASE_PASSWORD: ""set me"" MY_API_KEY: ""set me"" But as the team grows and we want everybody to be able to deploy on staging, it becomes more and more difficult to have the right settings for each developpers and each service. I found out 3 workarounds, and their reason to not be used: Use Google KMS - allows us to put encrypted secrets directly into the project, but it requires us to put custom code in our apps to decrypt them. It creates a different environment management between local, staging and production. It increases the risk of bugs due to the complexity. Store secrets in Google Datastore - I tried it, I created a helper that searches env vars in proccess.ENV, then in cache and ultimately in Datastore. But like KMS, it increases complexity a lot. Store secrets in a JSON file and put in on Google Cloud Storage : again, it requires to load env variables through an helper that checks env vars, then loads the file etc... Ultimately, we are exploring the feasibility to use a deployment server that would be triggered by developers or Continuous Integration and handle all the secrets injection when deploying to App Engine. But these tools like Ansible , Salt, Puppet, Chef only have plugins for Compute Engine and do not support App Engine. +-------------------------+ +-------------------+ +---------------------+ | | | +---> | | Developer workspace | | Ansible | | App Engine STAGING | | +----> (or other) | | | +-------------------------+ | | +---------------------+ | | +-------------------------+ | | +---------------------+ | +----> Injects secrets | | | | Continous Integration | | | App Engine PROD. | | | | +---> | +-------------------------+ +-------------------+ +---------------------+ This leads me to 3 questions: Do you think using a deployment server with App Engine is a good idea ?

37646581,Can Ansible unarchive be made to write static folder modification times?,"I am writing a build process for a WordPress installation using Ansible. It doesn't have a application-level build system at the moment, and I've chosen Ansible so that it can cleanly integrate with server build scripts, so I can bring up a working server at the touch of a button. Most of my WordPress plugins are being installed with the unarchive feature, pointing to versioned plugin builds on the official wordpress.org installation server. I've encountered a problem with just one of these, which is that it is always being marked as ""changed"" even though the files are exactly the same. Having examined the state of ls -Rl before and after, I noticed that this plugin (WordPress HTTPS) is the only one to use internal sub-directories, and upon each decompression, the modification time of folders is getting bumped. It may be useful to know that this is a project build script, with a connection of local . I guess therefore that means that SSH is not being used. Here is a snippet of my playbook: - name: Install the W3 Total Cache plugin unarchive: > src=[URL] dest=wp-content/plugins copy=no - name: Install the WP DB Manager plugin unarchive: > src=[URL] dest=wp-content/plugins copy=no # @todo Since this has internal sub-folders, need to work out # how to preserve timestamps of the original folders rather than # re-writing them, which forces Ansible to record a change of # server state. - name: Install the WordPress HTTPS plugin unarchive: > src=[URL] dest=wp-content/plugins copy=no One hacky way of fixing this is to use ls -R before and after, using options to include file sizes but not timestamps, and then md5sum that output. I could then mark it as changed if there is a change in checksum. It'd work but it's not very elegant (and I'd want to do that for all plugins, for consistency). Another approach is to abandon the task if a plugin file already exists, but that would cause problems when I bump the plugin version number to the latest copy.
