Centos User Privileges.
by Alessandro Baggi 22 Oct '15

22 Oct '15

Hi list, I've installed C 7.1.1503 and I've noticed that simple user can run from bash shutdown -h now/reboot without getting special permission (sudo, su). The machine is a VM without GUI (tested also on physical machine). From reddit I've got a suggestion: removing/comment out "-session optional pam_systemd.so" in /etc/pam.d/system-auth the problem is solved. This is a bug? If not, why use this policy? There are security implication? Thanks in advance.

Centos 7 - "Device eth1 does not seem to be present, delaying initialization".
by Rafał Radecki 21 Oct '15

21 Oct '15

Hi All :) I have three servers, all with centos 7 installed 3 days ago. I need on them "old" naming scheme (ethX) for network interfaces, because of that: # grep GRUB_CMDLINE_LINUX /etc/sysconfig/grub GRUB_CMDLINE_LINUX="rd.lvm.lv=centos_node-XY/swap rd.lvm.lv=centos_node-XY/root rhgb quiet ipv6.disable=1 net.ifnames=0" net.ifnames=0 was added and afterwards I ran: grub2-mkconfig -o /boot/grub2/grub.cfg Then I created /etc/udev/rules.d/70-persistent-net.rules with content: SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:67:7f:9c:98", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:67:7f:9c:99", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:67:7f:9c:9a", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:67:7f:9c:9b", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:67:81:37:0d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth4" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:67:81:37:0e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth5" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="90:e2:ba:46:ef:30", ATTR{type}=="1", KERNEL=="eth*", NAME="eth6" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="90:e2:ba:46:ef:31", ATTR{type}=="1", KERNEL=="eth*", NAME="eth7" After reboot it worked fine for all 3 servers, but some time later after another reboot I get: # systemctl status network network.service - LSB: Bring up/down networking Loaded: loaded (/etc/rc.d/init.d/network) Active: failed (Result: exit-code) since Tue 2015-10-20 20:37:30 CEST; 13h ago Process: 2034 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=1/FAILURE) Oct 20 20:37:24 node-X systemd-sysctl[2049]: Overwriting earlier assignment of net/bridge/bridge-nf-call-ip6tables in file '/etc/sysctl.d/99-sysctl.conf'.

I also noticed that on one of them when I saw the problem and rebooted the server eth1 was correctly assigned afterwards but after another reboot the message happened again. Quite strange to me :D Have you had similar problems on centos7? Any advice? Thanks :) BR, Rafal.

Libvirtd hooks in Centos 7
by Maikel van Leeuwen 21 Oct '15

21 Oct '15

I would like to create some libvirt hooks. This is so the hypervisor can execute some scripts during starting or stopping of a KVM guest. According to https://www.libvirt.org/hooks.html they must be present. However, it seems in Centos 7 these hooks are gone in /etc/libvirt/ Libvirtversion: 1.2.8-16.el7_1.4 OS version: CentOS Linux release 7.1.1503 (Core) Anyone how solved this riddle? I already asked this question on centos.org/forums, but didn't get much information apart from: "Unfortunately I suspect that CentOS libvirt packages have hooks disabled. I was looking for the same thing (needed some hooks for live migration) but it didn't work. However, after installing qemu from oVirt repository, hooks started working..." Anybody has more information then this given answer? -- Maikel van Leeuwen

Hi, folks, Haven't found the answer to this in googling: I want wifi never to be turned up. I mean, this is on a workstation that's hardwired, and doesn't have wifi.... Obviously, I want this persistent. mark

Google Chrome Issues on CentOS 6
by Tim Evans 21 Oct '15

21 Oct '15

I've installed Google Chrome using the Richard Lloyd 'install-chrome.sh' script (http://chrome.richardlloyd.org.uk/) and am finding a couple of nagging issues. (Current install is google-chrome-stable-46.0.2490.71-1.x86_64). First, every time I shut down Chrome and start it back up, it whines about not having been shut down "properly." Second, and worse, at start up, it complains about not finding my profile, then doesn't remember any logins/passwords. Even after re-entering such for several sites, the above repeats next time Chrome starts. Anyone seen/solved this? -- Tim Evans |5 Chestnut Court 443-394-3864 |Owings Mills, MD 21117

CentOS 6 update issues
by John Cenile 21 Oct '15

21 Oct '15

Hello all, I manage a few servers overseas that are running CentOS 6. When performing a yum update, it fails because it's trying to download from: mirror.centos.org/centos/*6.6*/extras/x86_64/repodata/repomd.xml Which fails due to the fact that the entire 6.6 directory is empty on all of the mirrors I have checked. From what I can tell it should be using: mirror.centos.org/centos/*6*/extras/x86_64/repodata/repomd.xml Does anyone have any idea why this would be happening? Obviously changing the CentOS-Base file to use 'baseurl' rather than 'mirrorlist' is a workaround, but I would prefer a more permanent solution, and would like to know why this is happening. Thanks in advance.

openssl with FIPS140-2 ??
by Fred Smith 21 Oct '15

21 Oct '15

I see that CentOS does not provide the FIPS140-2 package for openSSL. I don't know if RH provides it or not. Can someone advise me on the best way to get it onto a CentOS or RHEL system, without breaking things? I'd also appreciate ANY related wisdom that's available, having pretty much NO wisdom of my own. thanks!
