The corresponding plus kernel, kernel-2.6.32-279.19.1.el6.centos.plus, has been built with CONFIG_ARPD=y and is now available from mirrors. Akemi

Question: How to utilize multi-core CPUs
by Mike Watson 24 Dec '12

24 Dec '12

I've installed CentOS 6.3 on a quad-four box. The model only indicated dual core but CentOS is telling me there are four. This is the first multi-core Linux installation I've had. What is the best way to utilize the multi-core CPUs? I'd like to distribute the load but I'm unsure how to do that. mw -- -- "Lose not thy airspeed, lest the ground rises up and smites thee." -- William Kershner http://crucis-court.com http://www.crucis.net/1632search

selinux - centos 6.3 - mail
by Gregory P. Ennis 24 Dec '12

24 Dec '12

Everyone, I recently had a disc drive failure on a centos 5.8 internal mail server. I replaced the drive and installed centos 6.3. I had selinux turned off on the 5.8 machine, and with the upgrade to 6.3 decided to leave selinux active with the hopes I had learned enough to be able to use it. I have a couple of perl scripts that are activated by email that prints the contents of the mail packet on a printer. I have been able to fix the temporary directories that are used with changes of selinux permissions, but I have not been able to make everything work with the command : $arg = ("lp -o raw -d $LPT $MAILFILEO"); system($arg); I get the following log entry : Can't exec "lp": Permission denied at /usr/local/bin/s.printer.process line 190, <FILEI> line 19. Any ideas how I can get 'lp' to accept usage from the 'mail' user account? Everything works ok when selinux is turned off. I would like to keep it on at this point. Thanks, Greg Ennis

Postfinger
by Robert Moskowitz 24 Dec '12

24 Dec '12

This is a utility for Postfix; a bit old, but in a couple of threads over on the postfix list on researching issues with my postfix questions it was suggested that I give postfinger a try. Does anyone have an rpm for it for Centos 6.3?

I small deficiency in postfix 2.6.6 on Centos 6.3
by Robert Moskowitz 23 Dec '12

23 Dec '12

posfconf debugger_command does not work. This is a 'known' problem with 2.6 and fixed in postfix 2.9. This is tied into the large code rewrite in 2.9, and thus cannot be patched in 2.6. You can see my thread on this over on the postfix list. There was a comment how those running 4 year old code can look forward to the new troubleshooting and support features in 2.10...

Waiting for CentOS to thaw....
by Vlad K. 23 Dec '12

23 Dec '12

Hello list, I've put CentOS 6.3 x86_64 on my desktop, replacing Fedora 17 x86_64. This is the first time I'm using CentOS on a desktop, so far only on the servers. The problem is with thawing from hibernation. Time from turning on the hibernated machine to reaching the login prompt is not that of an issue, although sometimes it can take a while (significantly more than with Fedora). The problem is after I log in. It appears that none of the running programs will have thawed until I click their tabs in the taskbar, when the disk crunching begin and the program is unresponsive for up to a minute or two until it loads up from disk I guess, regardless of how much I wait between login and clicking a tab int taskbar. The biggest problem is with Firefox. I keep several tabs open and it takes literally minutes for it to become responsive. Even the terminal takes several seconds. During that time the window does not render except it's title bar and outer border. This is on the very same hardware (btw, it's AMD Phenom II X2, 4GB of RAM) where Fedora was running just a few weeks ago. Help? -- .oO V Oo. Work Hard, Increase Production, Prevent Accidents, and Be Happy! ;)

NFSv4 on CentOS 5.5
by Tim Gustafson 23 Dec '12

23 Dec '12

Hi, What is the magic juju that I have to put in /etc/sysconfig/autofs to get autofs to default to using NFSv4, rather than NFSv3, for mounting file systems? I don't want to place these flags into the automount maps themselves because we have a varied network with Sun, CentOS, RedHat and Macintosh systems, and the flags that have to get added to automount maps (which we distribute centrally through LDAP) are different for each OS. So, I'd prefer to specify the local machine options in /etc/sysconfig/autofs rather than in the global automount map. Thanks! -- Tim Gustafson tjg(a)soe.ucsc.edu 831-459-5354 Baskin Engineering, Room 313A

Virtual Machine Manager Centos 6
by Theo Band 22 Dec '12

22 Dec '12

I upgrade to CentOS6 from 5. The new (well, for me at least) virt-manager is much changed with respect to the one in 5. I miss cpu usage percentage and memory usage (both in percentage and the absolute amount). Is there a way the get this information quickly in an overview? I just want to have an idea of how much memory is consumed by the virtual machines and if there is enough free for a new machine. This information and the cpu info I need to decide if a machine should be migrated to another host. When I used Xen in the past, it was easy. xm list just showed a column with memory. Then I went over to KVM and could only use virsh list. Or virsh dominfo, but that is per virtual host. So since then simply started virt-manager. Theo

An ipmitool question
by m.roth＠5-cent.us 21 Dec '12

21 Dec '12

We have some new blades, and last night we got a bunch of messages about CPU temp exceeding threshold, throttling CPU. Running ipmitool sel shows nothing. ipmitool sdr list shows me current values, nothing special. First question: why would high temps not show up in the SEL? Second: among the things I see list are <...> 10-VR P1 | 56 degrees C | ok 11-VR P2 | 46 degrees C | ok <...> Does anyone know what the numbers mean, if anything, and what VR means? mark
