Dell Poweredge R300
by Nicholas 07 Jun '09

07 Jun '09

Hi all, Just found out that the Poweredge R300 cant even load the CentOS 5.2 64bit installer. Had to revert to Ubuntu. Seems its a driver problem. Pity, but does this kind of case apply to many other servers? --- OSCC MAMPU MyMeeting Version 2.0 Release http://knowledge.oscc.org.my/solution-areas/application/mymeeting

Sometimes it will go for days without rebooting then today it has rebooted 6 times at random times. I have modified grub.conf to go back to 2.6.18-92.1.22.el5xen on my dom0 and my only domU so we will see what happens (or hopefully doesn't happen) the next few days. I have a 3.0 P4 CPU with HT that does not support 64-bit so it's running an i686 kernel. It does have a Broadcom NIC like an earlier post was suspicious of: 02:08.0 Ethernet controller: Intel Corporation 82562EZ 10/100 Ethernet Controller (rev 02) 02:09.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet (rev 02) I have upgraded about 8 other servers with no random reboot problems but they are all running on a newer processors with a 64-bit kernel. -- Dave Jones

Changing a user's shell on CentOS Directory Server?
by Matt Harrington 02 Jun '09

02 Jun '09

Should unprivileged users be able to change their shell with lchsh on 5.3 and, if it matters, CentOS Directory Server? lchsh seems to require more open permissions than those which come with a default installation: Error initializing libuser: could not open configuration file `/etc/default/useradd': Permission denied.

looking for better graphical download manager for X / KDE / Gnome
by Rudi Ahlers 31 May '09

31 May '09

Hi all, I currently use kget to download files, but find it lacks a lot of features, like bandwidth throttling, auto-resume when internet disconnects & reconnects, download from multiple locations, browser integration, etc. FreeDownloadManager for Windows does all of the above quite well, but I don't use Windows @ home. So, does anyone know of a good alternative to use? I have searched the yum repositories, but don't see anything. -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Adding a kernel module to the ISO/installer initrd?
by Tim Nelson 31 May '09

31 May '09

Greetings list! Because of the sheer number of box (re)installations we do that have a CentOS base, I've converted our provisioning process to PXE. However, I've found that an alarming number of motherboards are coming with the Realtek RTL8168 ethernet controller onboard. When the system boots, it cannot find an ethernet controller and the installer process hangs. I made a new initrd from a running system that was installed via CD and had the kernel module installed afterwards. However, when using the new initrd to PXE boot a new box, it dies saying something about not being able to use/find /dev. The original initrd from the ISO is 5.1MB whereas the initrd I built from the working system is only 2.4MB. I have a feeling that the initrd I built (using mkinitrd -v --with=r8168 <path to output initrd> <kernel version>) does not include modules required by the installer. So, my question is this: is there a way to (1) create an initrd with ALL available modules or at the very least, (2) take the original ISO initrd and simply add the module I need? This initrd will need to work with all of the other hardware I support and should not be specialized for this single motherboard if possible. I've been up and down Google/CentOS Wiki/etc and cannot seem to find a valid way of doing either of the above. Suggestions, ideas, help? Tim Nelson Systems/Network Support Rockbochs Inc.

Possible bug in yum requirements handling with yum-priorities
by Kai Schaetzl 30 May '09

30 May '09

Just upgraded my perl-DBD-SQLite rpmforge package to 1.25 which resulted in all applications trying to use it to fail. As it turns out the following happened: Newer versions of DBD::SQLite need a DBI version of at least 1.57. The rpmforge package *does* include this requirement. However, CentOS includes DBI 1.52 and doesn't provide newer versions. As a good administrator I'm using yum priorities and thus the software is locked at the CentOS version. I would think that yum should not have upgraded perl-DBD-SQLite if it cannot fulfill the requirement of perl-DBI >= 1.57. Or is this expected behavior? Should I open a bug report? For anyone hitting this problem: - either exclude perl-DBD-SQLite in the rpmforge repo - or exclude perl-DBI* from the CentOS base and updates repos (this will update to DBI 1.607 plus two dependencies, works fine) Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com
