CentOS 7.x Russian certification
by Gorazd 18 Aug '17

18 Aug '17

Dear all, does anyone have any idea where to get a list of all CentOS 7.x versions that are certified to be used within Russia. My guess is that organizations, such as FSTEK, TR-CU declares those versions/distributions of CentOS that are certified to be used with commercial projects in Russia. Anyone with some information on this, plase advice, I would be very grateful. Regards, Gorazd

Power Fail Protection Update
by Chris Olson 17 Aug '17

17 Aug '17

Many thanks to those that responded to my original posting with information about Network UPS Tools and commercial UPS products. In our planning a path forward to implement UPS-based power fail protection, we have come across what appears to be an issue with the state of the CentOS 6 machines being UPS protected. Most of these machines are desktop/deskside machines that are likely to be idle during non-work hours. It is also likely that they will be hibernating or in a power save mode. In the power save mode, these machines do not respond to keyboard or mouse activity. They also do not respond to network traffic such as a ping from other systems on the network. The method we use to wake them up is a quick push on the power button when the hibernation state is indicated by the button's yellow LED display. This state of hibernation leaves us wondering if these systems will be able to respond to network messages sent by the UPS. We have not yet made it all the way through the NUT and UPS documentation. The hibernation answer may very well be therein, but we have not found it so far. Any help or direction regarding the hibernation issue as it relates to UPS power fail protection will be appreciated. Thanks again and best regards.

The release, which came as part of the monthly CentOS release stream, was a modest one, including only a single glibc bugfix update (https://lists.centos.org/pipermail/centos-announce/2017-July/022505.html) The next Atomic Host release will be based on the RHEL 7.4 source code (https://seven.centos.org/2017/08/centos-linux-7-1708-based-on-rhel-7-4-sour…) and will include support for overlayfs container storage, among other enhancements. Outside of the Atomic Host itself, the SIG has updated its Kubernetes container images to be usable as system containers (http://www.projectatomic.io/blog/2016/09/intro-to-system-containers/) What's more, in addition to the Kubernetes 1.5.x-based containers that derive from RHEL, the Atomic SIG is now producing packages and containers that provide the current 1.7.x version of Kubernetes. ## Containerized Master The downstream release of CentOS Atomic Host ships without the kubernetes-master package built into the image. You can install the master kubernetes components (apiserver, scheduler, and controller-manager) as system containers, using the following commands: # atomic install --system --system-package=no --name kube-apiserver registry.centos.org/centos/kubernetes-apiserver:latest # atomic install --system --system-package=no --name kube-scheduler registry.centos.org/centos/kubernetes-scheduler:latest # atomic install --system --system-package=no --name kube-controller-manager registry.centos.org/centos/kubernetes-controller-manager:latest ## Kubernetes 1.7.x The CentOS Virt SIG is now producing Kubernetes 1.7.x rpms, available through this yum repo (https://github.com/CentOS/CentOS-Dockerfiles/blob/master/kubernetes-sig/mas…) The Atomic SIG is maintaining system containers based on these rpms that can be installed as as follows: ### on your master # atomic install --system --system-package=no --name kube-apiserver registry.centos.org/centos/kubernetes-sig-apiserver:latest # atomic install --system --system-package=no --name kube-scheduler registry.centos.org/centos/kubernetes-sig-scheduler:latest # atomic install --system --system-package=no --name kube-controller-manager registry.centos.org/centos/kubernetes-sig-controller-manager:latest ### on your node(s) # atomic install --system --system-package=no --name kubelet registry.centos.org/centos/kubernetes-sig-kubelet:latest # atomic install --system --system-package=no --name kube-proxy registry.centos.org/centos/kubernetes-sig-proxy:latest Both the 1.5.x and 1.7.x sets of containers have been tested with the kubernetes ansible scripts (https://github.com/kubernetes/contrib/tree/master/ansible) provided in the upstream contrib repository, and function as drop-in replacements for the installed rpms. If you prefer to run Kubernetes from installed rpms, you can layer the master components onto your Atomic Host image using rpm-ostree package layering with the command: `atomic host install kubernetes-master`. The containers referenced in these systemd service files are built in and hosted from the CentOS Community Container Pipeline (https://wiki.centos.org/ContainerPipeline) based on Dockerfiles from the CentOS-Dockerfiles repository (https://github.com/CentOS/CentOS-Dockerfiles/tree/master/kubernetes) ## Download CentOS Atomic Host CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, or as an installable ISO, qcow2 or Amazon Machine image. For links to media, see the CentOS wiki (https://wiki.centos.org/SpecialInterestGroup/Atomic/Download) ## Upgrading If you're running a previous version of CentOS Atomic Host, you can upgrade to the current image by running the following command: $ sudo atomic host upgrade ## Release Cycle The CentOS Atomic Host image follows the upstream Red Hat Enterprise Linux Atomic Host cadence. After sources are released, they're rebuilt and included in new images. After the images are tested by the SIG and deemed ready, we announce them. ## Getting Involved CentOS Atomic Host is produced by the CentOS Atomic SIG (http://wiki.centos.org/SpecialInterestGroup/Atomic) based on upstream work from Project Atomic (http://www.projectatomic.io/) If you'd like to work on testing images, help with packaging, documentation -- join us! The SIG meets weekly on Thursdays at 16:00 UTC in the #centos-devel channel, and you'll often find us in #atomic and/or #centos-devel if you have questions. You can also join the atomic-devel (https://lists.projectatomic.io/mailman/listinfo/atomic-devel) mailing list if you'd like to discuss the direction of Project Atomic, its components, or have other questions. ## Getting Help If you run into any problems with the images or components, feel free to ask on the centos-devel (http://lists.centos.org/mailman/listinfo/centos-devel) mailing list. Have questions about using Atomic? See the atomic (https://lists.projectatomic.io/mailman/listinfo/atomic) mailing list or find us in the #atomic channel on Freenode. ------------------------------ Message: 2 Date: Tue, 15 Aug 2017 20:20:53 +0000 From: Johnny Hughes <johnny(a)centos.org> To: centos-announce(a)centos.org Subject: [CentOS-announce] CESA-2017:2456 Critical CentOS 6 firefox Security Update Message-ID: <20170815202053.GA55144(a)n04.lon1.karan.org> Content-Type: text/plain;

Power Fail Protection
by Chris Olson 15 Aug '17

15 Aug '17

Some of our largest systems run Windows because it supports engineering applications that we use regularly. These applications have unattended runs that often take between ten and fifteen hours to complete. We have taken the recommendation of the application supplier and equipped these Windows machines with UPS protection for 30 minutes at full load. The UPSs are Ethernet connected. A support application on the Windows engineering machine communicates with the UPS to detect and address any facility power failure. The long run engineering application is then suspended at a restart point and the system is shut down. We initiate job completion manually from the suspension restart point after the system has reliable power and is rebooted. If we wanted to protect our CentOS systems from facility power failure in a similar way, is there operating system or other standard support that we might employ? Most of the Linux-based applications are not as critical as the engineering applications on the Windows machines. There is a significant amount of processor idle time on several of the CentOS systems during non-work hours when the systems are unattended. Several CentOS systems are supported currently with UPSs, but they run out and the system loses power if it is unattended.

Custom kickstart post section on usb thumbdrive
by Jerry Geis 14 Aug '17

14 Aug '17

Hi All, I am attempting to create a custom USB drive for kickstart install. I found this: 1. get the ISO file of CentOS 7 2. mount -o loop CentOS-7.0*.iso /mnt/ 3. mkdir -p /CentOS-7-ISO-respin/{CentOS-7-unpacked,CentOS-7-iso} 4. rsync -avz /mnt/ /CentOS-7-ISO-respin/RHEL-7-unpacked 5. put your kickstart file into /CentOS-7-ISO-respin/RHEL-7-unpacked 6. add a new line to /CentOS-7-ISO-respin/RHEL-7-unpacked/isolinux/isolinux.cfg (this way you can use the ISO also from a DVD) label linux_ks menu label ^Install CentOS 7 with Kickstart kernel vmlinuz append initrd=initrd.img inst.stage2=hd:sdb2:/ ks=hd:sdb1:/ks.cfg 7. create the ISO with: /usr/bin/genisoimage -untranslated-filenames -volid 'CentOS-7.0-KS-x86_64' -J -joliet-long -rational-rock -translation-table -input-charset utf-8 -x ./lost+found -b isolinux/isolinux.bin -c isolinux/ boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table 8. dd if=/CentOS-7-ISO-respin/CentOS-7-CSB-iso/CentOS-7.0-KS-x86_64-DVD.iso of=/dev/XXX (where XXX is the Device Name of your USB drive without the partition number e.g. /dev/sdb) (Careful, that command destroys all data on the Stick) But I would also like to create a custom directory on the ISO and put some files in there for a custom POST section. I was not able to find an example with a custom POST section on the ISO. Anyone have any examples? Thanks, Jerry

Centos 7 specific cure for Spamassassin DNS lookup problem
by Gary Stainburn 14 Aug '17

14 Aug '17

I have the following error message in my /var/log/spamd spf: lookup failed: available_nameservers: No DNS servers available! Having Googled the error message I've found a number of responses which involve patching Perl or Spamassassin or other cures. Before I start changing things I was wondering if there was a Centos 7 specific resolution. Where possible, on production machines I prefer to stay with RPM's rather than amending software directly. Also, many of these responses are over 10 years old, so I'm a little sceptical about their success today. Gary

what is CodeMeter and why is it running on my CentOS box?
by Fred Smith 13 Aug '17

13 Aug '17

I just stumbled over /var/log/CodeMeter, which contains a number of large log files. I know I'm getting old and forgetful, but I can't remember intentionally installing that package. Yum just says "installed" instead of listing a repo. Looking at codemeter.com, it seems to work with something called a "cm stick". I don't have one, don't want one, and never heard of them. Is there any reason I should be leery of just "yum remove"ing the package? thanks!

13 Aug '17

Hi all, I am trying to install oVirt 4.1.x from centos repos but it seems ovirt-engine doesn't exists. But instead, ovirt-hosted-engine-setup exists? Is ovirt-engine package removed? In the official oVirt repos, exists. Thanks.
