screensaver: waiting for darkness
by Michael Hennebry 26 Dec '12

26 Dec '12

I'm using the default desktop for CentOS 6. My screensaver is set for blank, 5 min, no locking. In the seconds during which the screen fades to black, I cannot make it come back. Neither the keyboard nor moving and clicking the mouse has any affect. Until the screen goes black, I cannot do anything with the computer. How, if at all, can I change that? -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Darkness theare and nothing more." -- Edgar Allan Poe

Yum search for unavailable file!
by Ashkan Rahmani 26 Dec '12

Hi, I'm trying to install ant on my centos 6.3, this is behind a http (only http and not ftp) proxy server. after execute yum install ant, I got some error which indicate mirror speed is extremely low, less than 1bps! and go to test another mirror and error cycle starts again. this is error: "http://wftp.tu-chemnitz.de/pub/linux/centos/6.3/updates/x86_64/repodata/e2e…: [Errno 12] Timeout on http://ftp.tu-chemnitz.de/pub/linux/centos/6.3/updates/x86_64/repodata/e2e0…: (28, 'Operation too slow. Less than 1 bytes/sec transfered the last 30 seconds') Trying other mirror." i tried to get http://wftp.tu-chemnitz.de/pub/linux/centos/6.3/updates/x86_64/repodata/e2e… manually but it seeems there is not any file there. for test I tried o install some other application (joe, geany, ) and every things worked well. what is the solution? info: ipv6 is disabled, fastest mirror is enable, proxy enabled and configured in yum.conf... any thing else? uh, centos is uptodate -- Best Regards, Ashkan R < ashkan82r(a)gmail.com >

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...
