hi all, If I have a shell script on 5.1 that has 2 commands in the script... command1 command2 and command1 runs until it is kill'ed by some other process. Sometimes command2 runs and sometimes it doesnt (this is what it seems like). How can I be ensured that command2 will always run after command1 is killed? The script is not killed just command1. Thanks, jerry

When I install some RPMS like openoffice 3 on centos x85_64 is there some command that will leave all the actual files alone (leave them installed) but just remove the RPM name from the RPM database so centos now things the packages are not installed? Reason is I was wanting to do this so a next yum update does not get all confused... and the yum update happens just like I never installed

Hi, My both CentOS 5 servers have logging problems. Logs such as messages, boot.log, kernel, spooler, and tallylog in /var/log directory are all 0 size. The kernel is: Linux 2.6.18-92.1.22.el5 #1 SMP. Since the /var/log/messages contained no information it would be impossible to troubleshoot the problem. I am very sure both systems have not been hacked by others. Sincerely, Frank Ling

Hi! It appears that there have been some changes to tzdata recently. We run an application that needs the server to stay at GMT. Previously, we used the Casablanca timezone but now there seems to be a 1 hour difference to GMT. I checked the London zone and they seem to change time too. I tried to change the zone to GMT with system-config-date (i'm using command line remotely) but

I just updated and rebooted a VM host server which runs CentOS 6.5/x86_64. After rebooting, I can't start the virtual-manager due to the error: Error starting Virtual Machine Manager: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash.
