Last few days in CentOS
by Karanbir Singh 12 Jun '15

12 Jun '15

Hi, Its been a while since I did the last update post - so this one is going to be a bit longer. Distro ---------- * Updates for CentOS Linux 5/6/7 : All updates from upstream are released into the CentOS mirror network. * Rolling ISO media for CentOS-7 for May 2015 was released : http://lists.centos.org/pipermail/centos-announce/2015-June/021160.html ; this is media rebuilt with the last installer, but includes all updates released upto the 28th of May. - Vagrant box for CentOS Linux 7 is now released : http://lists.centos.org/pipermail/centos-announce/2015-June/021162.html ; we will try and keep these updated on a monthly cycle. CentOS 5 and 6 images are coming soon. - There has been lots of progress on the CentOS Linux ARM efforts, on both the v7 and the aarch64 side of things. The aarch64 ( arm 64bit platform ) is currently in beta mode ( http://lists.centos.org/pipermail/arm-dev/2015-May/000206.html ), and has been used in vendor demos ( http://www.eweek.com/servers/cavium-system-makers-unveil-arm-based-servers-… ). - ARMv7 efforts are also moving along nicely, this effort is being run entirely community centric. You can follow progress on the arm-dev list at http://lists.centos.org/mailman/listinfo/arm-dev; We have a baseline tree ready, including images for the raspberry pi2 and the cubietruck. Its an ongoing effort with plenty of opportunity to contribute and get involved. - The Cloud SIG announced release for OpenStack Kilo on CentOS Linux 7 and OpenStack Juno on CentOS Linux 6 ( http://lists.centos.org/pipermail/centos-devel/2015-May/013388.html ). Using the following three steps, any minimal base CentOS Linux 7/x86_64 install can run a complete demo cloud : $ sudo yum install centos-release-openstack-kilo yum-utils $ sudo yum install openstack-packstack $ packstack --allinone News & Others ---------- - The CentOS project is taking part in the Google Summer of Code effort through 2015. You can find details on the projects, the people working on them, the mentors in the excellent summary posted by Karsten at http://seven.centos.org/2015/06/centos-and-gsoc-2015-suddenly-come-seven-on… - We have a Calendar for IRC meetings ( and maybe we can add all CentOS related events there.. ) http://seven.centos.org/2015/06/centos-irc-meeting-calendar-now-available/ thanks to Brian for getting this done. - Some of us are going to be Red Hat Summit in a couple of weeks time, if you are attending do stop by and say hi. We should have some tshirts and stickers to hand out, and will also be doing demos of CentOS-7/i686 as well as CentOS-7 on ARMv7 and aarch64. ---------- Tip: Did you know that we run a remote ipxe install service that allows you to install any CentOS version / release very easily ? check it out at http://boot.centos.org/ and read the info page at http://wiki.centos.org/HowTos/RemoteiPXE Regards, -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

NetworkManager / wireless on latest Centos7 installs
by johan.vermeulen7＠telenet.be 12 Jun '15

12 Jun '15

Hello All, on the latest installs I've done, on 2 different types of Latitude laptops, with 3 different wireless cars, of Centos7 and Mate desktop, it looks to me like NetworkManager is nog managing wireless. When clicking the nm icon in the top right corner, I'm not seeing access points. Wifi seems enabled [root@localhost ~]# nmcli g STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN connected full enabled enabled enabled enabled but unmanaged [root@localhost ~]# nmcli d DEVICE TYPE STATE CONNECTION enp0s25 ethernet connected enp0s25 lo loopback unmanaged -- wlp12s0 wifi unmanaged -- I always start from a minimal install. Then I install X Window packages, and Mate The only difference I can think of, is that I now installed from Centos7.1 minimal install media, and before from Centos7 DVD. But there I also select minimal install. How can I change this? Greetings, Johan

CentOS 7 Repeating Update Messages
by Kirk Bocek 11 Jun '15

I've install yum-cron on a new CentOS 7 host and after a recent update I am now getting daily repeating emails about that update instead of the single notification I was expecting. Does anyone know what's going on? Kirk

Effectiveness of CentOS vm.swappiness
by Markus "Shorty" Uckelmann 11 Jun '15

11 Jun '15

Hi all, This might not be CentOS related at all. Sorry about that. I have lots of C6 & C7 machines in use and all of them have the default swappiness of 60. The problem now is that a lot of those machines do swap although there is no memory pressure. I'm now thinking about lowering swappiness to 1. But I'd still like to find out why this happens. The only common thing between all those machines is that there are nightly backups done with Bacula. I once came across issues with the fs-cache bringing Linux to start paging out. Any hints, explanations and suggestions would be much appreciated. Cheers, Shorty

sudoers
by Chris Olson 11 Jun '15

11 Jun '15

My experience with RHEL and CentOS is quite limited, andwould classify me as novice. I have been running CentOS 6for a little over a year and recently brought up a CentOS 7system as a virtual machine under Windows 7. One of the first things I usually do after installation isedit the /etc/sudoers file using visudo to give a specificuser or specific users privileges as indicated in the fileexcerpt below. The visudo editor issued no error messageswhen creating the line for sarah. ## user MACHINE=COMMANDS ## ## The COMMANDS section may have other options added to it. ## ## Allow root to run any commands anywhere root ALL=(ALL) ALL sarah ALL=(ALL) NOPASSWD: ALL On our CentOS 6 systems, the NOPASSWD option works as itis intended to work. No password prompt is presented for commands such as "sudo cat /etc/sudoers". On CentOS 7,the NOPASSWD option does not seem to work, and a promptfor sarah's password is always issued. Can someone help solve this CentOS 7 mystery? Thank you and best regards.

newbie question on installation over existing Linux
by Kay Schenk 11 Jun '15

11 Jun '15

If I choose to do a fresh install of CentOS 6 with "replace existing Linux systems", will it also wipe out my /home directory? In the past when I've done this with another Linux distro, /home was not affected. Or, would I need to do "fresh" install and then muck with partitioning using a Custom Layout? Right now, it's kind of looking like the latter to me, and if so, will I lose data? I spent some time on the Forums and reading the RH documentation, but, no real answers to this specific question. Thanks for any help. -- -------------------------------------------- MzK "We can all sleep easy at night knowing that somewhere at any given time, the Foo Fighters are out there fighting Foo." -- David Letterman

Hello All, I have the problem described in this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1116756 It is also descibed in some detail here: https://bugs.launchpad.net/linuxmint/+bug/1264811 After printing, the print icon stays in the system tray until I logout. The bugzilla says there is a fix for Fedora21. Does anybody know how to get this fixed for C7? Thanks very much. Greetings, Johan

Why is sha256-generic preferred over sha256-ssse3?
by Steve Snyder 10 Jun '15

10 Jun '15

The newly-released kernel v2.6.32-504.23.4.el6 includes the back-ported SHA256-SSSE3 driver. Why is the generic version of the SHA256 driver selected at runtime instead of the SSSE3 version on this x86_64 system? Yes, my CPU does support the SSSE3 instruction set, and the use of SHA256 is invoked by the LUKS "cipher=aes-cbc-essiv:sha256" option. On the running system I see that the sha256-ssse3 driver is not loaded. Further evidence that the generic driver is in use: # grep sha256 /proc/crypto name : sha256 driver : sha256-generic So... what's the trick to using the sha256-ssse3 driver instead of the generic driver? Thanks.

Resize KVM NTFS file system
by Mark LaPierre 10 Jun '15

10 Jun '15

Hey all, I resized a partition inside a KVM RAW file system disk image. When I start the Win7 virtual machine it does not report the new partition size. It shows the file system as 15GB instead of the 50GB size of the partition that it lives on. I gather from hours so reading the manual that I need to increase the NTFS file system size to fill the new larger partition where it lives. The ntfresize command does not seem to be compatible with disk image files. Do I have to mount the disk image file with a loopback first? I tried doing it inside the Win7 VM using the disk management tools but that didn't work either. Any suggestions welcome. -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****
