Create podman volume with custom path
|
I am trying to create a volume with custom path, I want the volume data path to be /home/$USER/data instead of default path which is ~/.local/share/containers/storage/volumes . I have googled it but could not find the result, so I got help from chatGPT, then as per the guidance I have created the volume using below command: podman volume create -o device=/home/$USER/data myvol the volume got created podman volume inspect myvol { "Name": "myvol", "Driver": "local", "Mountpoint": "/home/noor/.local/share/containers/storage/volumes/myvol/_data", "CreatedAt": "2023-03-01T15:58:43.923688206+05:30", "Labels": {}, "Scope": "local", "Options": { "device": "/home/noor/data" }, "MountCount": 0, "NeedsCopyUp": true, "NeedsChown": true } but when I run the container I get the below error. podman run -it -d --name apache -v myvol:/usr/local/apache2/htdocs -p 8080:80 httpd Error: error mounting volume myvol for container 0715cd8b6a02ac6ff069c2053a40992e4cacfff1d18fad6fa0e12b551dc10335: mount: /home/noor/.local/share/containers/storage/volumes/myvol/_data: permission denied. Any guidance would be helpful.

how to change repository location on gitolite?
|
I recently installed gitolite on my linux server. This server is my git remote server with some bare repositories located on a separate path. lets say /images/git_bare_repos By default gitolite is installed on git user in home directory. I am able to clone gitolite-admin repository from the root user on the same machine. That is gitolite is working fine. >>>ls /home/git bin gitolite projects.list repositories root.pub all the new repositories are created in repositories directory: >>>ls /home/git/repositories/ gitolite-admin.git testing.git My question is: I want gitolite to create new repositories on the same path where all my other bare repositories rest. Ie. in /images/git_bare_repos I tried adding: GL_REPO_BASE => "/images/git_bare_repos", in .gitconfig.rc file but with no luck.

Does the mysql client package version on webserver affect PHP queries?
|
I have two RHEL servers, one to host the PHP application, one to host the MySQL server. Database server has MySQL Enterprise version 5.6.21 installed. While getting the application server built, I asked that the rpm MySQL-client-advanced-5.6.21-1.el6.x86_64 be installed (to match server), but the hardware people don't like this version since 5.6.27 is available which addressed some vulnerabilities. The question is the following: Does the mysql client version on the application server affect the database queries coming from the PHP application? We're using PDO to connect to and query MySQL. If we do this, does the application server even need a mysql client library? Please let me know if I can clarify. Thanks!

Convert video to OGV, on fedora platform
|
I need to develop a rest API for publishing and converting videos. A major hurdle that I am facing, I need a free converter to convert video in any format to OGV. Even though ffmpeg is the best candidate, but I cannot use it because it is not in official Fedora repository, but in rpmfusion. I am developing a product that would be deployed on Fedora infra, they only deploy applications via packages into epel6. Can you guys suggest something from the official fedora repository ?

Use PHP mail to send via smtp
|
Does anybody know if you can configure php's mail() command so it will only use an SMTP server rather than the local sendmail? We are having trouble with emails being marked as spam. Our server is running RedHat 5 Enterprise. I am aware of various PHP libraries that act as an SMTP client but I'd rather configure PHP so mail() used an SMTP server directly.

Passing argument containg nullbyte (\x00) to subprocess.call
|
#!/usr/bin/env python from subprocess import call try: call(['echo', "aabbccddee".decode('hex')]) print 'Input without \\x00 works!' except Exception as e: print 'Input without \\x00 throws exception: ' + str(e) try: call(['echo', "aabbccdd00ee".decode('hex')]) # The input contains \x00 print 'Input with \\x00 works!' except Exception as e: print 'Input with \\x00 throws exception: ' + str(e) Returns the following (tested with Python 2.7 on RHEL 6): ▒▒▒▒▒ Input without \x00 works! Input with \x00 throws exception: execv() arg 2 must contain only strings Questions: Is this expected behavior by subprocess.call or might this be a bug? Is there any way I can pass binary data (directly) containing \x00 to another executable within a python script? It will probably work using shell=True, but I would prefer another way, if there is any. Note: >>> type("00".decode('hex')) <type 'str'> Running echo $'\x00' directly works as expected. EDIT This seems to be correct behavior after more research. Due to the execve(2) semantics it is not possible to pass a string containing a null byte as argument. See: $ echo $'\x55\x55\x55\x00\x55\x55' UUU However, I couldn't really find anymore info on this (second question especially, as it seems shell=True won't help either (all data after the null byte wouldn't be passed)). I leave this question open for a while, maybe someone can provide a deeper insight or share some useful resources on this.

Gitlab Runner: microdnf/yum command not found on different machine
|
I have two different server machine with gitlab-runner hosted. I use one as development version, the other one as production release. I have the same configuration on both machine, so the lastest release of gitlab-runner and the lastest release of Docker/docker-compose. Into my dockerfiles I need to download net-tools package in order to use netstat command. The builder docker is an official image of OpenJDK 14 and it is RHEL based. So, in order to install a new package, i can use only dnf/microdnf or yum. Ok, everything should work simple and clear as exposed so far. But... when the machines try to run the command: RUN microdnf install net-tools On staging machine: /bin/sh: microdnf: command not found Instead, on production machine: Job succeeded. Okay, so what about yum? Let's change Dockerfile's net-tools installation RUN yum install net-tools -y Pipeline started, job scheduled and... staging machine: Job succeeded. On production machine, as you can figure: /bin/sh: yum: command not found I feel i little bit trapped because there is not another way to install package (dnf should be another possible way but it is not install on both docker images) and I don't want apply a workaround that can "test" the installation via microdnf or yum. I hope I've made the problem as clear as I can.

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?

I'm getting Error when install Docker on RHEL
|
I'm newbie on Linux and Docker platform and trying to install Docker on RHEL by repository method as stated in Docker installation guide but when I type sudo yum -y install docker-ee I'm getting that output and I cannot continue to installation. I think that the previous steps performed correctly but can not go on other steps due to this output : [root@localhost yum.repos.d]# sudo yum -y install docker-ee Loaded plugins: langpacks, product-id, search-disabled-repos, : subscription-manager rhel-7-server-extras-rpms | 3.4 kB 00:00 rhel-7-server-rpms | 3.5 kB 00:00 (1/3): rhel-7-server-extras-rpms/x86_64/group | 104 B 00:00 (2/3): rhel-7-server-extras-rpms/x86_64/updatei | 280 kB 00:00 (3/3): rhel-7-server-extras-rpms/x86_64/primary | 446 kB 00:00 No package docker-ee available. Error: Nothing to do Previous steps by Docker guide : sudo rm /etc/yum.repos.d/docker*.repo export export DOCKERURL="<DOCKER-EE-URL>" sudo -E sh -c 'echo "$DOCKERURL/rhel" > /etc/yum/vars/dockerurl' sudo sh -c 'echo "7" > /etc/yum/vars/dockerosversion' sudo yum install -y yum-utils \ device-mapper-persistent-data \lvm2 sudo yum-config-manager --enable rhel-7-server-extras-rpms sudo -E yum-config-manager \--add-repo \"$DOCKERURL/rhel/docker-ee.repo" sudo yum-config-manager --enable docker-ee-stable-18.03 Current step : sudo yum -y install docker-ee What can be the problem ? Thank you so much

I want to maintain a separate variable file to store the user information rather then putting them in the same playbook file .

.Net Core application exit code. Different behaviour on Linux (RHEL 7)
|
I seem unable to set the exit code of a dotnet core console application such that the expected behaviour is observed on RHEL7. I am using dotnet 2.0.3. using System; namespace HelloWorld { class Program { static void Main(string[] args) { Console.WriteLine("Hello World!"); Environment.Exit(12345); } } } On windows, the error level is set correctly when executing the program with dotnet HelloWorld.dll echo %errorlevel% 12345 On RHEL7, this is not what is seen dotnet HelloWorld.dll echo $? 57 I have tried various ways to return an exit code (setting the Environment.ExitCode property, returning an integer from the program) but have had no success. I will try a test on the latest dotnet core version (2.1.302) as soon as possible but posting this question in the meantime. Does anyone know what's going on here? Thanks

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. Here's the code: #include <stdio.h> #include <unistd.h> #include <sys/time.h> #define N 225 #define DELAY_LOOPS 8000 main() { struct timeval _t0, _t1, _t2; double a[N][N], b[N][N], c[N][N]; double millisec, cum_ms; int i, j, k, l, m=0; gettimeofday( &_t0, NULL ); // for( l=0; l<DELAY_LOOPS; l++ ) for( i=0; i<N; i++ ) for( j=0; j<N; j++ ) { a[i][j]=0; b[i][j]=i; c[i][j]=j; } for( l=0; l<75; l++ ) { gettimeofday( &_t1, NULL ); for( i=0; i<N; i++ ) for( j=0; j<N; j++ ) for( k=0; k<N; k++ ) a[i][j]+=b[i][k]*c[k][j]; gettimeofday( &_t2, NULL ); millisec = 1000*(_t2.tv_sec-_t1.tv_sec); millisec += 1e-3*(_t2.tv_usec-_t1.tv_usec); cum_ms = 1000*(_t2.tv_sec-_t0.tv_sec); cum_ms += 1e-3*(_t2.tv_usec-_t0.tv_usec); printf( "%d: duration %fms, cumulative %fms\n", m++, millisec, cum_ms ); // sleep( 2 ); } printf( "a[%d][%d]=%f\n", N/2, N/2, a[N/2][N/2] ); } and here are the results: % icc -O2 -o test main.c; ./test 0: duration 13.049000ms, cumulative 13.677000ms 1: duration 13.026000ms, cumulative 26.753000ms 2: duration 12.911000ms, cumulative 39.668000ms 3: duration 12.913000ms, cumulative 52.584000ms 4: duration 12.914000ms, cumulative 65.501000ms 5: duration 12.911000ms, cumulative 78.415000ms 6: duration 12.912000ms, cumulative 91.331000ms /* snip */ 64: duration 12.912000ms, cumulative 840.633000ms 65: duration 10.455000ms, cumulative 851.092000ms 66: duration 5.910000ms, cumulative 857.004000ms 67: duration 5.908000ms, cumulative 862.914000ms 68: duration 5.907000ms, cumulative 868.823000ms 69: duration 5.908000ms, cumulative 874.732000ms 70: duration 5.912000ms, cumulative 880.646000ms 71: duration 5.907000ms, cumulative 886.554000ms 72: duration 5.907000ms, cumulative 892.462000ms 73: duration 5.908000ms, cumulative 898.372000ms 74: duration 5.908000ms, cumulative 904.281000ms a[112][112]=211680000.000000 I experience the problem regardless of optimization level (-O0, -O1, -O2, etc.). Does anyone know anything about how scheduling is done under RHEL6 Server? Is it so very different from RHEL5 Workstation? I presume the difference I'm seeing is more a function of the fact that one box is a server edition of RHEL and the other is a workstation edition (rather than the difference between release 5 vs. 6). Is there some simple way to reduce this effect under RHEL6 Server and make it act more like the RHEL5 Workstation boxes? Any ideas? Thanks.

Setup my first pipeline using Jenkin's Ocean Blue on a EC2 RHEL 8 instance and when attempting to run docker commands (such as as docker pull maven:3.6.2-jdk-14) as the jenkins user the following error is always returned No subuid ranges found for user "jenkins" in /etc/subuid From a bit of research it seems I need to add the jenkins user to /etc/subuid and /etc/subgid but I'm unsure how to do this or what to add. Any help will be much appreciated.

I have annonmous users to place files in /var/ftp/incoming. On a remote machine I can have the user successfully log in but could not place the file on the remove vsftpd server: $ftp mysql_server Connected to mysql_server (192.168.1.31). 220 Welcome to blah FTP service. Name (mysql_server:root): anonymous 331 Please specify the password. Password: 230 Login successful. Remote system type is UNIX.

Building FFmpeg on RHEL4
|
StackOverflow has yet to fail me, so don't let me down this time! I need to build FFmpeg on RHEL4 ... yes, 4! The version of make on RHEL4 is 3.80 , and the Makefile that ./configure generates when configuring FFmpeg does not seem to be compatible. When I make it throws a parse error every time. This happens on pretty much every software pkg I try and build. My applications group (at work) will not upgrade this machine, so please skip the suggestions to upgrade to RHEL5 or 6. What are my options for installing FFmpeg?

Malformed Block in Ansible
|
I'm trying to run a playbook that gathers yum history logs, and consolidates them on a single server. I ran this playbook --- - name: Gather yum history from all hosts hosts: all become: true tasks: - name: Run 'yum history' command shell: yum history register: yum_history_output - name: Save yum history to local file copy: content: | Host: {{ inventory_hostname }} ======================================== {{ yum_history_output.stdout }} ======================================== dest: "/tmp/yum_history_{{ inventory_hostname }}.log" - name: Fetch all yum history logs to control node hosts: all gather_facts: false tasks: - name: Fetch log files to control node fetch: src: "/tmp/yum_history_{{ inventory_hostname }}.log" dest: "./yum_history_logs/" flat: yes and, after some formatting, got a malformed block error which just seemed to put the whole playbook into a single block. What am I doing wrong? I was given a bunch of formatting issues that I fixed, mostly deleting a lot of spaces because it didn't like the spaces in vi, but now I get a malformed block, and have no idea what to do next.

microdnf shows librhsm-WARNING Found 0 entitlement certificates
|
Problem I am trying to install nmap-ncat package into a container created with this image by microdnf pkg-manager. I run microdnf update microdnf -y install nmap-ncat Both cmds output (microdnf:xxx): librhsm-WARNING **: 12:00:00.000: Found 0 entitlement certificates ... but both cmds seem to be working properly after this. I can actually see ncat cmd's help by --help option so it seems the install is complete. I googled about this issue and found this . It seems since I am not a red hat subscriber, Red Hat Enterprise Linux(RHEL) which is the OS used by the image limits what I can do. Maybe the base image of the image is one of red hat universal base images (ubi) by which allow commercial and open source developers to build containers based on RHEL without requiring them or their users to be RHEL subscribers (source) because the output of microdnf -y install nmap-ncat is like Installing: ... ;ubi-8-baseos Installing: ... ;ubi-8-appstream and this shows both ubi-8-baseos and ubi-8-appstream are RHEL 8 UBI repositories (but I am not really sure about this). My questions are Why did the warning come up while I successfully installed nmap-ncat? Am I entitled to use nmap-ncat with this image ?

Retrieve executable from core dump
|
I want to retrieve the executable from a core dump and the output of any linux package used to get this information should contain execfn in it's output. Here are the following things which I have tried so far : $ file kms kms: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from '/test', real uid: 1000440000, effective uid: 1000440000, real gid: 0, effective gid: 0, execfn: '/test', platform: 'x86_64' The file command only works for specific cores and it's not a generic solution because some core dump gives following output. $ file ss ss: ELF 64-bit LSB core file x86-64, version 1 (SYSV), too many program header sections (6841) gdb command doesn't work for all core dumps in the same manner. The output using gdb command is inconsistent. The output received by gdb command for some core dump is not the same as strings command. $gdb kms Core was generated by `/test'. I even tried strings package and I think it gives proper output but the format doesn't contain execfn for it to be used in my solution $ strings kms | grep ^/ | tail -1 /test Can anyone please suggest any linux package which will help me in retrieving executable from core dump which contains execfn in it's output.

Systemd exits with status=209/STDOUT
|
Scenario I have a systemd file which I want to run conditionally, but only if the environment variable ISCAPTUREPOD is set to true. I have a container which runs two services on startup, but there is a special scenario where I only want one of the services to run. I'm passing an environment variable via Kubernetes which I want to use to control whether the second service does or does not start. I have a script named iscapturepod.sh which checks the environment variable and it is part of an ExecStartPre statement. I want the script to succeed when the environment variable ISCAPTUREPOD is set to "True" and fail if it doesn't exist or is set to something other than "True". Problem: No matter what I do ExecStartPre fails. I have even tried just making the script say exit 0 . That's the only thing in the entire script just because I wanted to force a success.

Systemd exits with status=209/STDOUT Scenario I have a systemd file which I want to run conditionally, but only if the environment variable ISCAPTUREPOD is set to true. I have a container which runs two services on startup, but there is a special scenario where I only want one of the services to run. I'm passing an environment variable via Kubernetes which I want to use to control whether the second service does or does not start. I have a script named iscapturepod.sh which checks the environment variable and it is part of an ExecStartPre statement. I want the script to succeed when the environment variable ISCAPTUREPOD is set to "True" and fail if it doesn't exist or is set to something other than "True". Problem: No matter what I do ExecStartPre fails. I have even tried just making the script say exit 0 . That's the only thing in the entire script just because I wanted to force a success. Systemd still fails with status 209/STDOUT.

How do i specify a requirement for a minimum version of openssl in rpm spec file?
|
The rpm spec file for my package looks like this: Requires:mysql-server >= 5.5.30, java >= 1.6, p7zip, openssl >= 1.0.2g I have an RHEL system where the OpenSSL version is this: [ag@rhel1]# openssl OpenSSL> version OpenSSL 1.0.1e-fips 11 Feb 2013 [ag@rhel1]# rpm -q --whatprovides openssl openssl-1.0.1e-51.el7_2.4.x86_64 When I try to test the install of my rpm package, it is supposed to fail because my package requires a minimum of 1.0.2g whereas 1.0.1e is installed. However, the installation succeeds without any problem. What am I missing here?

add rule to firewalld in Centos7 to allow all traffic from a server
|
I have a small cluster with Centos7. I'm trying how to use the new firewalld. I need a rule to allow all traffic between those servers. I was able to do it with: sudo iptables -A INPUT -s [hostname] -j ACCEPT and it worked. But now I have to use firewall-cmd because of Centos 7. How can I add a rule to allow all traffic between my nodes? I'm trying to run MPI on them but the firewalld is rejecting the connection so the solution I thought of came to this. My current firewall-cmd configuration is: $ firewall-cmd --list-all work (default, active) interfaces: eno1 sources: services: dhcpv6-client ipp-client ssh ports: masquerade: no forward-ports: icmp-blocks: rich rules:

What causes this error message when using the postgres pg_dump command?

I am attempting to dump an entire PG Database from hosting on a GCP/GCE instance ( RHEL 8.x VM ). The purpose is to transfer the .sql file to another RHEL 8.x VM on GCE and restore the database. I am running this script as OS user 'postgres' #!/bin/bash clear export PGUSER=<pg_user> export PG_DATABASE=<pg_db> export PGHOSTADDR=<pg_ip_addr> export PGPORT=5432 SQL_FILE=<pg_db>.sql export PGPASSWORD=<passwd> pg_dump \ --format plain \ --no-owner \ --verbose \ --file $SQL_FILE \ $PG_DATABASE If there is anything else recommended in a script to dump a database to a .sql file for restoration: anything recommended adding to the script, or any way to improve the script that you are aware of), please advise. I get this error when running the script: (have PostGIS installed) pg_dump: last built-in OID is 16383 pg_dump: reading extensions pg_dump: identifying extension members pg_dump: reading schemas pg_dump: reading user-defined tables pg_dump: error: query failed: ERROR: permission denied for table us_lex pg_dump: error: query was: LOCK TABLE public.us_lex IN ACCESS SHARE MODE Why is permission denied when running as OS user postgres . What permission would I need to add (full/exact command), to add whatever permissions are needed? Or how could I exclude this table? I don't think I need it, and it would be recreated with the installation of a new Postgres instance.

How to install Python 3.8.1 on RHEL 8 UBI container with dnf?
|
How do I install and run Python 3.8.1 on Linux? Python.org does not offer a Linux binary for Python 3.8.1. I want to type: dnf -y install python or dnf -y install python38 and have it install Python 3.8.1 on my RHEL 8.0 or 8.1 inside my minimal container that I want to keep small. How would I make this happen? I don't even see a download for Python for Linux on python.org. Do people use Python on Linux? There are no Linux binaries to be downloaded from Python.org I have searched all over (internet search), and cannot find a way to install Python 3.8.1 easily on a minimal container. I do not want to download the source and compile, because it is a small container that I am trying to keep small without a lot of overhead. Reference: [URL]

How to run podman commands on host from within container
|
In case of docker, this can be achieved by mounting docker.sock inside container. But since there is no daemon in podman. What's the replacement for docker.sock? I want to typically check the podman images presents on host and start a new container. I'm using Podman with --privileged=true and root.

How to mount HostPath Volume in Kubernetes with SELinux
|
I am trying to mount a hostPath volume into a Kubernetes Pod. 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. Turning off SELinux is not an option. I can see that Kubernetes mentions SELinux security contexts in the docs here , but I haven't been able to successfully mount a hostPath volume into a pod without getting the permission denied error. What does the YAML need to look like to successfully enable a container to mount a HostPath volume from an underlying host that is running SELinux? Update: The file I am accessing is a CA certificate that has these labels: system_u:object_r:cert_t:s0 When I use the following options: securityContext: seLinuxOptions: level: "s0:c123,c456" and then check the access control audit errors via ausearch -m avc -ts recent , I can see that there is a permission denied error where the container has a level label of s0:c123,c456 , so I can see that the level label works. I have set the label to be s0 . However, if I try to change the type label to be cert_t , the container doesn't even start, there's an error : container_linux.go:247: starting container process caused "process_linux.go:364: container init caused \"write /proc/self/task/1/attr/exec: invalid argument\"" I don't seem to be able to change the type label of the container.

Podman Non-Root "Error setting up pivot dir"
|
First time posting on StackOverflow so please be gentle! I'm setting up a new RHEL8 server to run Podman. Previously, I've done this on a pretty vanilla server but this one is setup in line with our corporate image. This means a homedir that is mounted over NFS. When I try a simple podman command such as podman run centos , I get a couple of errors (see below). According to [URL] , Podman non-root is known to have problems with NFS homedirs. Output from podman run centos (and others): ❯ podman run centos Resolved "centos" as an alias (/etc/containers/registries.conf.d/000-shortnames.conf) Trying to pull quay.io/centos/centos:latest...

Write txt file in linux for .net Core (Docker)
|
I am new in Linux and my API was created in .net core and running in Docker. The system i create will write/create a txt file that will input all errors logged in the API. My code to write is this public class WriteLogs { public void ErrorLogFile(string traceNo, string errorMsg) { DirectoryInfo dir = new DirectoryInfo(Startup.errorPath); if (!dir.Exists) { dir.Create(); } using (StreamWriter swLog = File.AppendText(Startup.errorPath + Startup.errorFileName + DateTime.Now.ToString("MMddyyyy") + ".txt")) { swLog.WriteLine(DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss.fff") + " - Trace Number : " + traceNo + " " + errorMsg + "\n"); } } } the value in my startup is located in my appSettings.json file : "ErrorPath": "C:\\BP\\", "ErrorFileName": "BP-ParamLogs_", This is working in windows environment but when i transfer my program to linux and change the ErrorPath to: "ErrorPath": "/home/Logs/", the file was not created. My question is, do my syntax works in linux to write txt file or my path was wrong?

bash kill process if it takes too long to shutdown
|
I have a group of supervisord run process that I want to automate starting and stopping with a script. But sometimes the supervisor shutdown command takes too long to complete and wait times start to pile up. Currently I am doing: for each in "${args[@]}"; do (supervisorctl -c configs/supervisord_${each}.conf shutdown) & sleep 8s & (kill -9 ps aux | grep supervisor| grep ${each} | a wk '{print $2}' && kill -9 ps aux | grep supervisor| grep ${each} | awk '{print $2}') done Is there a cleaner way I can kill the supervisor process, after a few seconds, if it takes too long to stop? To be clear, I am trying to kill the supervisor process that I am trying to shutdown with supervisorctl -c {config path} shutdown , and not the supervisorctl shutdown command itself.

Approach for installing system service implemented as Ruby gem
|
After years of being away from Ruby, I'm back full-force and have just cut my first gem, which includes an executable. Everything works like a charm. The problem I am facing, however, is that I ALSO have a startup script (not part of the gem istelf) that daemonizes the executable. Additionally, I'd also like for the startup script to point the executable at configuration in a place like /var/ To the best of my knowledge, there's no way with rubygems, gemspec, etc., to specify files getting blown out to other parts of your system during install (e.g. startup script to /etc/init.d, and config to /var/). It certainly wouldn't make sense if you COULD do that. So... my question is... what IS the proper procedure for automating the installation of something like this. I'm using RHEL, and am wondering if it's, perhaps, time for me to get my feet wet with making my first RPM. Any thoughts?

How to fix "An error ocurred while loading the archive." in Archive Manager in RHEL 7.6 when opening ZIP files?
|
When I try to open a ZIP file in the Archive Manager, I get this error: "An error ocurred while loading the archive." This issue is happening on a virtual machine running Red Hat Enterprise Linux 7.6. Oddly, this did not happen to me prior to this year 2022. Things worked OK in 2021 and each year before. How do I fix this error "An error ocurred while loading the archive?" I reverted to an old snapshot of my RHEL 7.6 virtual machine and I can now open ZIP files in the Archive Manager with zero errors. I think a system setting was edited OR a newly installed program is causing the issue.

Docker image just contain software without OS
|
I have a PROD environment running on RHEL 7 server. I want to use docker for deployment. I want to package all the software and apps in a Docker image, without a base OS. Because I don't want to add an additional layer on top of RHEL. Also, I could not find an official base image for RHEL. Is that possible? I see some old posts mentioned about "FROM scratch" but looks it does not work in the latest version of Docker -- 1.12.5. If this is impossible, any suggestions for this?

BCP neither gives results nor outputs anything when using valid statements but it does throw errors when passing invalid parameters

I have to use bcp command-line tool to export data from an SQL Server database to a file in a Red Hat server. I am (apparently) using valid statements but bcp is not producing any kind of output/results. However, when I execute statements with missing or invalid parameters it displays the respective error.

RHEL service wouldn't start using Puppet

But the service is not started (no entries in log either). However, if I manually run service gitlab start, it works fine. I noticed that there is a line saying "Unscheduling refresh on Service[gitlab]". Not sure why and if it has anything to do with it. Any advice? Thanks.

python daemon killed (by kernel?)
|
I have a python2.7 daemon process using a module from [URL] The process is a heavy one with about 40 GB RAM usage and 9 child threads. Server uses RHEL 6.3 with 192 GB RAM and enough CPU power. After starting the process, it lasts for around 3-7 hours, but then it was killed by someone, might be the kernel. But I could not find any hints in dmesg nor kernel log (which I had manually activated), nothings there. When not starting as daemon, I just got the message in terminal: "killed". The following precautions have been done: resetting the oom score in /proc//oom_score_adj so that the oom killer does not pick the process when sort of resources increasing all rlimits (that can be increased) to maximum set the process nice/priority higher (prio -15) This problem exists already before applying these precautions, so they are not responsible for the killing I also have a mechanism to catch all exception, STDERR, STDOUT and log everythings into a rotated log file. But there was nothing interesting just before the process died. Modules used within the process among others: oracle_cx, ibm_db, suds, wsgi_utils. But all of them always write logs when errors occured. Anyone know how to trace back the killing? Who and why? Thank you in advance

'docker stop' 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).

pip + why pip removing the current version while we not identify the option force-reinstall

I am installing the following python module pip install ipaddress-1.0.23-py2.py3-none-any.whl the pip failed on Processing ipaddress-1.0.23-py2.py3-none-any.whl Installing collected packages: ipaddress Attempting uninstall: ipaddress Found existing installation: ipaddress 1.0.16 ERROR: Cannot uninstall 'ipaddress'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall. What isn’t clear here why pip trying to uninstall the current pkg - ipaddress 1.0.16 As all can see we not using the option --force-reinstall So why pip install is removing the current - ipaddress 1.0.16 ? Reference - Difference between pip install options "ignore-installed" and "force-reinstall"

error: command 'gcc' failed with exit status 1 while installing GDAL for Python3 on AWS EC2

I'm trying to install GDAL to use with Python 3 on an AWS EC2 Amazon2 machine (RHEL7). Following the instructions on this page: Install GDAL on Python 2.7 on a Amazon Linux virtual server I managed to get it working for python 2.7 ("import gdal from osgeo" works). However, I need it to work for python3 installed on my machine. I tried to adjust the instructions accordingly, and got to this set of commands: sudo yum-config-manager --enable epel sudo yum -y install make automake gcc gcc-c++ libcurl-devel proj-devel geos-devel gdal-devel gdal-python python3-devel sudo yum -y update cd /tmp curl -L [URL] | tar zxf - cd gdal-2.4.0/ ./configure --prefix=/usr/local --with-python sudo make -j4 sudo make install python3 -m pip install numpy --user sudo -H pip3 install --upgrade pip CPLUS_INCLUDE_PATH=/usr/include/gdal C_INCLUDE_PATH=/usr/include/gdal sudo python3 -m easy_install GDAL -d /usr/lib/python3.7/site-packages --include-dirs=/usr/include/gdal when I run the last command, the installation tries to run but fails with: "error: command 'gcc' failed with exit status 1". There are many errors before that, such as: /usr/local/include/cpl_vsi_error.h:58:24: error: ‘CPL_FORMAT_STRING’ has not been declared CPL_FORMAT_STRING(const char *fmt), ... ) ^~~~~~~~~~~~~~~~~ In file included from extensions/gdal_wrap.cpp:3173:0: From what I gather, the gcc can't find the GDAL headers, but it is specified in the command and I also did the including commands above: CPLUS_INCLUDE_PATH=/usr/include/gdal C_INCLUDE_PATH=/usr/include/gdal Any ideas will be helpful!

Chrony lose connection with local host after 10 minutes
|
I'm trying to configure chrony on RHEL 7.4. I configured the local clock (127.127.1.0) as a source, and chrony get time from it for about 10 minutes and then chrony stops receiving packets from it ('chronyc sources' shows 0 packets reached), although using tcpdump shows that ntp packets are sent to the local clock and back to localhost (also running 'chronyc ntpdata' shows it does not get time from the local clock). My chrony configuration: server 127.127.1.0 iburst peer 192.168.11.7 iburst local stratum 10 driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync 'chronyc sources' while it works: After 20 minutes: Also using tcp dump I figured that after starting chrony the packets from 127.127.1.0:123 looks correct, stratum and reference-id looks good, and after a few minutes the stratum written in the packets grow up to 15 and then all the later packets have "Stratum 0 (unspecified)" and also "Reference-ID: (unspec)". Any ideas?

Move a Perl script with dependencies from one computer to another
|
I have a Perl script on an old RHEL4 x86_64 Linux computer. This script runs only on this computer, and we'd like to run it on other Linux computers. The issue is there are a ton of Perl .pm and .xs files needed. I've done the following Created a virtual machine that has the same directory structure as the RHEL4 x86_64 Linux computer. I have run into errors this way, namely the Config.pm file aborting. Used the PAR Packager pp command to package the Perl script. I keep running into errors when packing it. What other routes can I take in executing the script on other Linux computers?

The standard upgrade path suggested by rhel here requires that the machine is registered to receive updates from Subscription Management. And the subscription status on my machine says Unknown . # subscription-manager list +-------------------------------------------+ Installed Product Status +-------------------------------------------+ Product Name: Red Hat Enterprise Linux Server Product ID: 69 Version: 6.8 Beta Arch: x86_64 Status: Unknown Status Details: Starts: Ends: Has anybody been able to successfully upgrade it on EC2 instances?

installing rpm packages inside of a virtual python environment (virtualenv or pyvenv) on rhel 6 with no internet access
|
My RHEL server only has access to packages that are pre-approved by my IT. I'm developing an Python application that will be hosted on this server. For now, I've managed to build the latest version of python at a different location (/usr/local/bin). I'm able create virtual environments to isolate it from the rest of the system. Now, I need to install packages using pip in the environment to get the app to work eg. Django. Since every access to the internet has been disabled by IT, I cannot do pip install package_name. Well, I can but it tries to download the package from the internet and times out. When I download the rpm of the django package and try to install it in the virtual environment, it fails: (envtest) [root@arlwebimgakp02 envtest]# rpm -ivh python3-django-1.7.2-1.fc22.noarch.rpm error: Failed dependencies: /usr/bin/python3 is needed by python3-django-1.7.2-1.fc22.noarch python(abi) = 3.4 is needed by python3-django-1.7.2-1.fc22.noarch python-django-bash-completion = 1.7.2-1.fc22 is needed by python3-django-1.7.2-1.fc22.noarch python3 is needed by python3-django-1.7.2-1.fc22.noarch So it looks like the rpm install is looking for dependencies from the universal install of python (2.6.6) instead of the separately compiled 3.4.3 which is used in the virtual environment. Can I even do this? Can I install an rpm package to just a virtual environment? How else can I get my python packages to install in my virtual environments without internet access to the server?

no such repository on migrating to a new cvs server
|
I am moving from cvsserv1 to cvsserv2. I am running cvs1.11 on current server on RHEL. I am moving to cvsserv2 which is running ubuntu 12. This is my procedure to port cvs: zip entire repository on cvsserv1 move zip to cvsserv2 extract zip to /home/users on cvsserv2. setup cvs service on cvsserve2 in pserver mode. initialize repository on /home/users/cvsroot by using "cvs -d /home/users/cvsroot init" connect to cvsserv2 from eclipse using anonymous access to do a test checkout. I am failing on step6 with the error message "no such repository". What am I doing wrong? UPDATE I tried to change the above method, by adopting this [URL] and I was partially successful. At step 3 (as in that link), after initializing repo on cvsserv2, I copied my repository to /var/lib/cvsd/project1, overwriting CVSROOT folder. Now, after finishing all steps, I was able to connect successfully. However, when I try to check out, I don't see any branches. When I tried to Refresh Tags, I receive the following error: What is going wrong?

yum update from wrong repository i
|
I am running a AWS Linux AMI in AWS, it seems to be RHEL under the covers and uses yum (kernel 3.4.62-53.42.amzn1.x86_64) . The amazon repo includes nginx 1.4.2 which is out of date so I removed it and re-installed using the repo given at nginx website. I did this as such: sudo yum remove nginx* sudo yum --disablerepo="*" --enablerepo="nginx" install nginx Note that yum priorities are disabled. I tried messing around with setting priority= in the repo files but decided disabling priorities made sense after reading up on it. /etc/yum.repos.d files : amzn-main.repo contains: [amzn-main] name=amzn-main-Base mirrorlist=[URL] mirror_expire=300 metadata_expire=300 priority=10 failovermethod=priority fastestmirror_enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-amazon-ga enabled=1 retries=5 timeout=10 report_instanceid=yes [amzn-main-debuginfo] name=amzn-main-debuginfo mirrorlist=[URL] mirror_expire=300 metadata_expire=300 priority=10 failovermethod=priority fastestmirror_enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-amazon-ga enabled=0 retries=5 timeout=10 report_instanceid=yes nginx.repo contains: [nginx] name=nginx repo baseurl=[URL] gpgcheck=0 enabled=1 priority=1 Now doing the update once nginx 1.4.3 is installed, it tries to install the old version from the amazon main repo: $ sudo yum update Loaded plugins: update-motd, upgrade-helper Resolving Dependencies --> Running transaction check ---> Package nginx.x86_64 0:1.4.3-1.el6.ngx will be updated ---> Package nginx.x86_64 1:1.4.2-1.12.amzn1 will be an update --> Finished Dependency Resolution Dependencies Resolved So not sure why its picking up the older version. Is there a way to configure yum to only update if the version is newer than currently installed? If there is no way, is there a way to skip nginx package when I do a general update and then update nginx using another command as described above that disables all repos and uses only nginx repo, here it is again: sudo yum --disablerepo="*" --enablerepo="nginx" install nginx

Incomplete output with psycopg2 and csv writer in python
|
I wrote the following python code that would write a portion of a postgresql table to a csv file using psycopg2 and python's csvwriter. The problem that I am having is that I get an incomplete csv file and I am not sure why. Typically, what I see is about 80 to 90% of the table in the csv file and usually the last row outputted in the csv file is incomplete as well. Running Python2.6.6 on RHEL6.4. Looking for some help for a work around on this issue. import psycopg2 import csv connection = psycopg2.connect('dbname=db user=user password=pass host=localhost port=5555') cursor = connection.cursor() cursor.execute('SELECT title,date,publisher,author FROM books;') with open('books.csv', 'wb') as csvfile: csvwriter = csv.writer(csvfile,delimiter=',',quotechar='|', quoting=csv.QUOTE_MINIMAL) csvwriter.writerow(['title,date,publisher,author']) for record in cursor: csvwriter.writerow(record) cursor.close() connection.close()

Failed Kerberos authentication when Debug logging enabled
|
I am currently running a RHEL 6 server with IPA and a user test_user defined, attempting to authenticate using the 'Krb5LoginModule' Login Module I am getting the exception at the bottom of this question. HOWEVER - if I add the system property -Dsun.security.krb5.debug=true the authentication completes without error - that system property is the only change between the failure scenario and successful scenario. The same username and password also work flawlessly in kinit from the same machine running the Java client. This is using Oracle jdk1.6.0_32. So the question is what else is different when debug logging is enabled that would change the behaviour of the login process? At the moment enabling debug logging to understand the failure didn't work as that in itself caused it to work. Exception in thread "main" javax.security.auth.login.LoginException: Integrity check on decrypted field failed (31) - PREAUTH_FAILED at com.sun.security.auth.module.Krb5LoginModule.attemptAuthentication(Krb5LoginModule.java:696) at com.sun.security.auth.module.Krb5LoginModule.login(Krb5LoginModule.java:542) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at javax.security.auth.login.LoginContext.invoke(LoginContext.java:769) at javax.security.auth.login.LoginContext.access$000(LoginContext.java:186) at javax.security.auth.login.LoginContext$5.run(LoginContext.java:706) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.login.LoginContext.invokeCreatorPriv(LoginContext.java:703) at javax.security.auth.login.LoginContext.login(LoginContext.java:575) at com.darranl.as.sasl.gssapi.KerberosLoginUtil.login(KerberosLoginUtil.java:50) at com.darranl.as.sasl.gssapi.KerberosLoginUtil.main(KerberosLoginUtil.java:131) Caused by: KrbException: Integrity check on decrypted field failed (31) - PREAUTH_FAILED at sun.security.krb5.KrbAsRep.<init>(KrbAsRep.java:72) at sun.security.krb5.KrbAsReq.getReply(KrbAsReq.java:446) at sun.security.krb5.Credentials.sendASRequest(Credentials.java:401) at sun.security.krb5.Credentials.acquireTGT(Credentials.java:373) at com.sun.security.auth.module.Krb5LoginModule.attemptAuthentication(Krb5LoginModule.java:662) ... 13 more Caused by: KrbException: Identifier doesn't match expected value (906) at sun.security.krb5.internal.KDCRep.init(KDCRep.java:133) at sun.security.krb5.internal.ASRep.init(ASRep.java:58) at sun.security.krb5.internal.ASRep.<init>(ASRep.java:53) at sun.security.krb5.KrbAsRep.<init>(KrbAsRep.java:50) ... 17 more

Java printing thread gets stuck : WHY?

Here is the stacktrace of the blocking thread : "Thread-211" #799 daemon prio=5 os_prio=0 tid=0x00007fca543a6800 nid=0x10755 runnable [0x00007fca02820000] java.lang.Thread.State: RUNNABLE at sun.print.CUPSPrinter.canConnect(Native Method) at sun.print.CUPSPrinter.isCupsRunning(CUPSPrinter.java:444) at sun.print.UnixPrintServiceLookup.getDefaultPrintService(UnixPrintServiceLookup.java:650) - locked <0x00000006d2c7fff8> (a sun.print.UnixPrintServiceLookup) at sun.print.UnixPrintServiceLookup.refreshServices(UnixPrintServiceLookup.java:277) - locked <0x00000006d2c7fff8> (a sun.print.UnixPrintServiceLookup) at sun.print.UnixPrintServiceLookup$PrinterChangeListener.run(UnixPrintServiceLookup.java:947) Other users trying to print documents and relatives threads are blocked by this one. I looked at the source code of CUPSPrinter.canConnect() (native code) and at this point we try to connect to the cups server : /* * Checks if connection can be made to the server. * */ JNIEXPORT jboolean JNICALL Java_sun_print_CUPSPrinter_canConnect(JNIEnv *env, jobject printObj, jstring server, jint port) { const char *serverName; serverName = (*env)->GetStringUTFChars(env, server, NULL); if (serverName != NULL) { http_t *http = j2d_httpConnect(serverName, (int)port); (*env)->ReleaseStringUTFChars(env, server, serverName); if (http != NULL) { j2d_httpClose(http); return JNI_TRUE; } } return JNI_FALSE; } In my case CUPS is on the same host listening on port 631. I checked the logs & everything seems to be fine. I also checked active connections for cups with netstat : tcp 0 0 0.0.0.0:631 0.0.0.0:* LISTEN 76107/cupsd tcp 0 0 127.0.0.1:45652 127.0.0.1:631 TIME_WAIT - tcp 0 0 :::631 :::* LISTEN 76107/cupsd tcp 0 0 ::1:35982 ::1:631 TIME_WAIT - tcp 0 0 ::1:35981 ::1:631 TIME_WAIT - tcp 0 0 ::1:35978 ::1:631 TIME_WAIT - tcp 0 0 ::1:35979 ::1:631 TIME_WAIT - udp 0 0 0.0.0.0:631 0.0.0.0:* 76107/cupsd Important notes : If I restart Cups service, thread is not deblocked. It seems to live endessly until application restarts. I found a bug similar to this on Open JDK : [URL] But the workaround of setting -Dsun.java2d.print.polling=false does not work for me (the property seems to be cleared at some point for an obscure reason, so PrinterChangeListener gets instantiated and though polling is not desactivated). I can't reproduce the problem with a test application (clone of production) on the same server Please HELP !!

I also checked active connections for cups with netstat : tcp 0 0 0.0.0.0:631 0.0.0.0:* LISTEN 76107/cupsd tcp 0 0 127.0.0.1:45652 127.0.0.1:631 TIME_WAIT - tcp 0 0 :::631 :::* LISTEN 76107/cupsd tcp 0 0 ::1:35982 ::1:631 TIME_WAIT - tcp 0 0 ::1:35981 ::1:631 TIME_WAIT - tcp 0 0 ::1:35978 ::1:631 TIME_WAIT - tcp 0 0 ::1:35979 ::1:631 TIME_WAIT - udp 0 0 0.0.0.0:631 0.0.0.0:* 76107/cupsd Important notes : If I restart Cups service, thread is not deblocked. It seems to live endessly until application restarts. I found a bug similar to this on Open JDK : [URL] But the workaround of setting -Dsun.java2d.print.polling=false does not work for me (the property seems to be cleared at some point for an obscure reason, so PrinterChangeListener gets instantiated and though polling is not desactivated). I can't reproduce the problem with a test application (clone of production) on the same server Please HELP !!

Podman images not showing with podman image ls
|
I am trying to setup a build server in a Red Hat Enterprise Linux 8 (CentoOS 8) virtual machine. I installed podman by running sudo dnf install -y @container-tools I then ran sudo podman pull mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim to pull a container image from docker: Trying to pull mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim...Getting image source signatures Copying blob e936bd534ffb done Copying blob caf64655bcbb done Copying blob 4156e490f05f done Copying blob 68ced04f60ab done Copying blob 7064c3d93b4a done Copying config e2cd20adb1 done Writing manifest to image destination Storing signatures e2cd20adb1292ef24ca70de7abaddaadd57a5c932d3852b972e43b6f05a03dea This looks successful to me. And if I run it again, I get told that the layers "already exists". But then I run: podman image ls and I get an empty list back: REPOSITORY TAG IMAGE ID CREATED SIZE I also tried the following commands to get a list: podman image ls -a podman image list podman image list -a podman images podman images ls podman images ls -a podman images list podman images list -a They all give an empty list. How can I see the container image that I pulled down? Update: I ran sudo podman run --rm --name=linuxconfig-test -p 80:80 httpd and (on another machine) browsed to the ip address of my linux machine and got It Works! shown. So podman is working at least in part.

Unicode character default collation table
|
I don't know which site this question belongs exactly, so posting it here. I use Postgresql 9.2 on RHEL 6.4 and observe the following: select foo from unnest('{а,ә,б,в,г,д,е,ж}'::text[]) as foo order by foo collate "kk_KZ.utf8" gives а ә б в г д е ж BUT select foo from unnest('{а,ә,б,в,г,д,е,ж}'::text[]) as foo order by foo collate "en_US.utf8" gives а б в г д е ә -- misplaced ж Further, I found that there is the Default Unicode Collation Element Table [1], which lists the character in question (04D9 ; [.199D.0020.0002.04D9] # CYRILLIC SMALL LETTER SCHWA) in proper order. I understand that it is silly to expect the cyrillic characters be handled properly by "en_US.utf8" locale, but what is the correct behavior by Unicode or any other relevant standards in cases, where a character does not normally belong to language/locale used for collation?

postgresql createuser -interactive not working in CentOS 7
|
A fresh installation of CentOS 7 needs a fresh installation of PostgreSQL, with a new user and a new role. I am following the steps described in this tutorial to accomplish this goal. However, the terminal is not providing the interactive menu that the tutorial promises when I type createuser -interactive . Instead, I get the following blank prompt: [this_centos_user@localhost ~]$ sudo -i -u postgres [sudo] password for this_centos_user: -bash-4.2$ createuser –interactive -bash-4.2$ What specific commands need to be typed in order to get the interactive createuser interface to appear and let me give a username, password, etc.? The Specific Situation: 1.) First, I installed the postgresql-server package and the "contrib" package with the following command: sudo yum install postgresql-server postgresql-contrib 2.) Next, I created a new PostgreSQL database cluster: sudo postgresql-setup initdb 3.) I then set up password authentication editing PostgreSQL's host-based authentication (HBA) configuration by typing sudo vi /var/lib/pgsql/data/pg_hba.conf and changing the following lines to include md5 instead of ident: host all all 127.0.0.1/32 md5 host all all ::1/128 md5 4.) After saving and exiting vi , I started and enabled PostgreSQL with the following: sudo systemctl start postgresql sudo systemctl enable postgresql 5.) Next, I logged in to PostgreSQL with the postgres account that we created above, and tried to create the user with the code from the top of the OP above, as follows: [this_centos_user@localhost ~]$ sudo -i -u postgres [sudo] password for this_centos_user: -bash-4.2$ createuser –interactive -bash-4.2$ So how do I create this user?

How to emulate class template argument deduction pre-C++17?
|
I am working on removing sscanf() calls from a C++ codebase and replacing them with the std::stringstream implementation described here: [URL] . The relevant code is: template<class Char> class imatch { const Char* s; public: imatch(const Char* x) :s(x) {} template<class Stream> friend Stream& operator >> (Stream& st, const imatch& m) { std::basic_string<Char> x; st >> x; //strip spaces, read chars up to space if(x!=m.s) st.setstate(st.failbit); //set as "failure" a mismatch return st; } }; Then in my codebase: std::stringstream ss("value = 15"); //the input int val=0; ss >> imatch("value") >> imatch("=") >> val; if(ss) { std::cout << "read value = " << val << std::endl; } else { std::cout << "read failed" << std::endl; } This uses class template argument deduction in the constructor calls. It works great...in C++17. The problem is that this code needs to compile all the way back to RHEL6, which only supports -std=c++0x at best (a subset of C++11). What is the most succinct way to write and use this class such that users can easily port their sscanf() calls to use it, without access to C++17?

RHE 7 Not respecting java Secure Random Seed
|
I have a quandary on my hands. I created an AES service to encrypt/decrypt sensitive information. The AES key is randomly generated using java's SecureRandom . I have a protected file that stores the seed and upon calling the service the seed is populated into the Secure Random class. To make sure it works I have the following logic: private boolean secureRandom(final String seed) { SecureRandom sr1 = new SecureRandom(seed.getBytes(UTF8_CHARSET)); SecureRandom sr2 = new SecureRandom(seed.getBytes(UTF8_CHARSET)); //Two secure random with the same seed should generate the same results boolean secureRandomWorks = sr1.nextLong() == sr2.nextLong(); if (!secureRandomWorks) { System.err.println("Secure random not supported. Defaulting to old key"); } return secureRandomWorks; } The idea here is I should be able to create two secure random objects with the same seed and they should both return the same value upon the call to nextLong() When I deploy my application on a windows machine this works fine, but when I deploy it on a RHEL 7 machine I get my error. I was under the impression that as long as the seed is the same, both instances will always produce the same output. This seems to be the case on windows, but not when I tested it on RHEL 7 this doesn't seem to be the case. I created this simple test to see verify: SecureRandom sr1 = new SecureRandom("encryptionKey".getBytes("UTF-8")); SecureRandom sr2 = new SecureRandom("encryptionKey".getBytes("UTF-8")); for (int i = 0; i < 1000; i++) { System.out.println(sr1.nextLong() == sr2.nextLong()); } And on windows every output was true while on RHEL 7 this was false. Any idea's suggestions on what might be causing RHEL 7 to ignore the seed?

ImportError: /lib/libc.so.6: version `GLIBC_2.14' not found (required by /usr/lib/libpq.so.5)
|
I have to run a tornado webapp on a server using psycopg2 with postgresql as backend. I am working on Red Hat Enterprise Linux Server release 6.5. I set up a virtual environment. Now, on this server, i don't have root access, i can't use pip or yum and i can't copy text from the server(so i can't post the exact error log). I have been manually downloading tar files for the libraries and installing them. When i try to run the webapp, i get the following error: ImportError: /lib/libc.so.6: version `GLIBC_2.14' not found (required by /usr/lib/libpq.so.5) The version for libc.so.6 is 2.12. The error is displayed in psycopg2/ init .py. I apologize as this is not much to go on, but the server has a lot of restrictions. Any help will be appreciated.

prevent rpmbuild from reading ~/.rpmmacros
|
Is there a way to prevent the rpmbuild command from reading the ~/.rpmmacros file? I want to add rpmbuild to a Make target and want to get a consistent build under any user account, regardless of the options somebody might have personally set in the rpmmacros file in his home directory. How can I do this? Or, is that actually a bad idea?

Sudo NOPASSWD not registering/working/showing
|
Sudo version: 1.7.2p1 I have the following (sanitised) lines in my sudoers file (at the end of the file): Runas_Alias GROUPALIASNAME = user1,user2, user3 Cmnd_Alias APP = /path/to/binary/setup -f *, /path/to/binary/patchbinary %groupname ALL=(root)NOPASSWD:SOFTWARE,(GROUPALIASNAME)NOPASSWD:APP If I run "sudo -ll" as a user from %groupname (user3) I get the following: Sudoers entry: RunAsUsers: root Commands: NOPASSWD: /bin/rpm, /usr/bin/up2date, /usr/bin/yum RunAsUsers: user1, user2, user3 Commands: /path/to/binary/setup -f *, /path/to/binary/patchbinary I can't seem to get the second "nopasswd" entry to work. I've tried removing all whitespace, adding whitespace. I've tried "NoPasswd:all" which just makes it give "all" rather than "nopasswd:all". I know the rule is matching because clearly I can see the very specific entries expanding. The entry being at the end should rule out any conflicting rules. Any ideas or suggestions on diagnosing this? Unfortunately its a 'secure' machine so applying patches/updating sudo isn't an option. **The reference to "SOFTWARE" is just a default sudoers entry. EDIT: For now I have worked around the issue by splitting the 1 line into 2 lines. I made no other modifications than to insert a line break with %groupname ALL= and it now correctly shows the right to execute the command with no password. However it still requires a password.

The same occurs for initialization with ffi.new() and a few other places. However, I thought that char * had the same property—but I was mistaken. In C you get the usual warning if you try to give a char * to a char ** argument, for example. Sorry about the confusion. This has been fixed in CFFI by giving for now a warning, too. It will turn into an error in a future version.

How to use -regex in the find command on Linux command line
|
The objective is to find and list anything with "messages" and/or "error.log" etc.. in the beginning then list both "messages.1..99" and "error.log.1..99" using regular expressions. This command works for however, it would require me to make many -or searches, but to simplify, I would like to have multiple in a set within the search. Like for instance: # find /var/log -maxdepth 1 -type f -size +1M -name [messages|error.log|secure.log|kern.log...]?[0-9]|[0-9][0-9] ! -iname "*.gz" not # find /var/log -maxdepth 1 -type f -size +1M -name "messages?[0-9]" -o -name "messages?[0-9][0-9]" How might I perform this command with regular expressions? # find /var/log -maxdepth 1 -type f -size +1M -name "[messages,error.log,kern,secure]?[0-9]" ! -iname "*.gz" My attempt with regex doesn't print anything in standard out: # find /var/log -maxdepth 1 -type f -size +1M -regex -name "[messages,error,kern,secure]?[0-9]" ! -iname "*.gz"

erlang is no longer supported by Red Hat Enterprise Linux?
|
I'm trying installing Erlang on my REHL7.2, but unfortunately I failed. I tried two approaches First I tried downloading a RPM package from official site of erlang (in fact the rpm package is for CentOS, but there's no RPM package for RHEL anyway), but error: Failed dependencies: libwx_baseu-2.8.so.0()(64bit) is needed by esl-erlang-19.0-1.x86_64 libwx_baseu-2.8.so.0(WXU_2.8)(64bit) is needed by esl-erlang-19.0-1.x86_64 Then I tried $ wget [URL] $ rpm -Uvh erlang-solutions-1.0-1.noarch.rpm But it failed too because No package erlang available. Error: Nothing to do I wonder whether Erlang is no longer supported by RHEL? Otherwise how can I install Erlang on my RHEL7.2?

Error: package does not exist. Is the issue code related?

I'm trying to compile Java code in RHEL 7 and i get this kind of errors error: package org.apache.xml.serialize does not exist import org.apache.xml.serialize.Method; symbol: class SistPrint location: class CrearSocketMIE ./GRP/Comunicaciones/ComMIE/CrearSocketMIE.java:187: error: cannot find symbol public SocketCliente getSocketMIE(int lan) { and so on, when i try in Ubuntu i don't get them... what am i seeing? is this code related or is the SO environment?. Both have the same jdk version (jdk1.8.0_65), how can they behave differently? What config am i missing (sure JAVA_HOME is already set) is there anything else?, I have a Make file that does different things depending the environment, really strange. What do you think?
