troubleshooting kernel crash?
by Kai Schaetzl 29 Apr '06

29 Apr '06

I'm getting kernel crashes on a new machine since it went into production some weeks ago. How can I troubleshoot this? I suspect a hardware problem, but I know too few about the kernel and kernel debugging on Linux to know how I can nail this down with debugging software. Just for reference of what kind these oopses are I quote the last two. The symptom is that the machine stops responding but is pingable. After a reset all is well until the next crash in ten days or so.

Alert icon for yum
by José Alburquerque 29 Apr '06

29 Apr '06

Hi all. I have a simple question: CentOS relies mostly on "yum" to keep systems up to date, although I understand that like on RHEL, "up2date" is also available. On my system I've run both KDE and GNOME as Graphical Desktops under X (though I presently run GNOME), and I've noticed that there is an applet called "CentOS Network Alert Icon" (from the "System Tools" menu) which when run appears in a "status area" in a panel to show whether the system needs updating or not. This applet shows the up2date sources, but my question is: Is there any way to have some sort of similar applet that does this for yum. I just think that when we add repos we usually add them through yum. Also when we update the system we usually use yum. Hence I think it would be better to use an applet similar to up2date's for yum so that there is no need to edit both yum and up2date files and there is consistency between when the applet signals a need for updating and the actual "yum update" command. Am I making sense? I found a site (http://fedoranews.org/tchung/yum-applet/) with the source for a yum applet. I know I can build this for myself, but I was wondering what others on this list think and whether such an applet should be more widely available to the general CentOS audience. Can I go ahead and build this for my system? TIA for your answers. Sincerely Jose Alburquerque

problem installing centos 4.0 on Compaq Presario SR1722IL
by ankush grover 29 Apr '06

29 Apr '06

hey friends, Recently I purchased Compaq Presario SR1722IL and I tried to install Centos 4.0 on it but it started showing errors like: Uniform CD-ROM driver revision: 3.20 Combo SOLTC-4836k ATAPI CD/DVD-ROM drive hdc: IRQ Probe failed (Oxfcfa) hdd: IRQ Probe failed (Oxfcfa) hdc: lost interrupt I tried installing FC4 also but same problem persist. Windows 2000 & Windows XP are already installed on the same system that means the Combo Drive is working fine. Then I tried installing SUSE 10.0 with the same Combo Drive and I faced no problem except when it starts "Gnome or KDE" it shows Frequency out of range.. What is the reason that FC4 and Centos4.0 are failing with the installation? What should I do to get rid of the problem ? Thanks & Regards Ankush Grover

Error in ghostscript ?
by Sam Drinkard 29 Apr '06

29 Apr '06

Just tried to run a perl script to do some ripping and converting of a postscript file, and ghostscript bombed out with the error message below. Can someone tell me is this really a ghostscript error, or is there more to it than this? If need be, I can attach the perl script that caused the error, but I think it is OK. Don't have another machine to test it on. Oh yeah, FWIW, this is an x86_64 machine. Thanks...

Running mount in a script.
by Michael Jacks 28 Apr '06

28 Apr '06

I am running CentOS 4 and have the need to run "mount -t cifs ..." from within a perl or bash script as part of an application. The application does not run as root. I have been trying to do a chmod +s on a root owned script but that doesn't seem to work. I still get permission errors. I also took a look at sudo but that appears to require a user to periodically enter a password. This would not work for this application. Does anyone have any suggestions on how to do a mount from a script based application not being run as root? Thanks for your help.

os update with plesk
by Melinda Odom 28 Apr '06

28 Apr '06

Hi, I have plesk server administration 7.5.4 on my server and am wanting to upgrade to plesk 8. Plesk 8 supports Centos 4.2 and the notes on the 4.2 readme say: http://mirror.centos.org/centos/4.2/readme If you know what you are doing, and absolutely want to remain at the 4.2 level, go to http://vault.centos.org/ for packages. If you follow the other link listed in that doc it goes to the centos vault with this text: http://www.centos.org/modules/smartfaq/faq.php?faqid=34 There is a CentOS Vault containing old CentOS trees. This vault is a picture of the older tree when it was removed from the main tree, and does not receive updates. It should only be used for reference. I will need to keep my server os at 4.2 because that is the only one plesk supports so according to those 2 articles and staying at centos 4.2 will the "vault" files be the one to use and will they get security updates?

Hi; As a prerequisite for IBM's db2 Viper they say: "For RHEL, all available compat-libstdc ++ RPM-packages must be installed." Can anyone please advise how to achieve this quickly via yum? (64bit software running on 64bit centos 4.3.) Thanks; nat
