Hi, We need a few people to help with the CentOS booth at Linux Expo in London, from the 23rd to the 25th.

Seeking advice about auth/home serving
by Laurent Wandrebeck 16 Oct '08

16 Oct '08

Hi, I'm currently using nis/nfs3/autofs in a small network (20 boxes), and planning on using a more secure/elegant method. The thing is, which solution to adopt ? The network is mainly composed of Centos boxes, and a couple MS/Win ones. ldap/kerberos/nfs4 ? Directory Server ? Anything else ? Another point is, we have several servers with a local /data. Is there any solution to make each /data accessible to each server without having to maintain an awful fstab list per server ? (no way to deploy gfs). Regards, Laurent.

I disagreed with the idea of creating a second list as originally proposed, however, I think two lists as you describe is a good middle ground and the remainder of this thread should be directed towards a compromise of this nature. -Ken

Postfix problem
by Paolo Supino 16 Oct '08

16 Oct '08

Hi I have a CentOS 4.2 server with postfix. The problem I'm having is that postfix insists on using $myhostname in the from field even if I instruct it to use $mydomain in /etc/postfix/main.cf or even if I hard code the domain name into $myorigin. What am I missing? BTW: postconf shows output shows that $myorigin is configured to use $mydomain, or the domain name itself ... -- ttyl Paolo

Rebooting CentOS 5.2 XEN Guest
by Brett Serkez 16 Oct '08

16 Oct '08

All, I have CentOS 5.2 XEN guests running on a CentOS 5.2 host. At one time when I issued an 'init 6' in one of the XEN guests it rebooted Now it seems to halt but virt-manager shows it as still running and the only way to get the guest to boot is to destroy the virtual machine and start it again. Unfortunately I didn't notice precisely when this change in behavior occurred, I believe it was the last 'yum update' that included a new XEN kernel, but I cannot say for sure. Has anyone else noticed this change in behavior? Any solutions to restore the older behavior, being able to 'init 6' the virtual machine was very useful. Thank you, Brett

How can I free the disk space after compiling kernel
by Ian jonhson 16 Oct '08

16 Oct '08

Hi, I have recompiled my kernel and updated it to kernel-2.6.27. However, I found there are no more than 1G disk space left for my jobs. How can I free my disk space but in the same time keep all the compiled kernel modules (*.ko files) here? Can I remove the *.o files created by kernel compiling? Are there any commands to help me achieve this? Thanks a lot, Ian

formatting large volume
by Craig White 16 Oct '08

16 Oct '08

I just got a new server with a Dell MD-1000 SAS unit and 6-750 gigabyte drives which are now initializing in RAID 10 which will give me just about 2 terabytes. I vaguely recall reading that fdisk wasn't suitable for partitioning and wonder if I shouldn't be using partd instead. I am also wondering if I should use lvm or just mkfs to create the filesystem. Anyone have suggestions before I blunder in? Thanks Craig

[OT] What is the best network monitoring tool?
by Alejandro 16 Oct '08

16 Oct '08

Hi all, Currently I have a big question. What is the best OPEN SOURCE solution for monitoring multiple Host and Services, for example for using in a WebHosting Provider with 50 hosts or more. Currently, I'm using NAGIOS for more than 3 years, this is a incredible tool, but before upgrade to version 3, I have this existential question. Please fill free to recommend any soft, but with this option in mind. 1- Easy option to personalize any plug-in 2- Good Documentation 3- Support large platforms 4- Run over Linux Sorry for me English Regards Alejandro www.linuxiso.com.ar from Buenos Aires, Argentina

OT: is parted reliable?
by Sergio Belkin 15 Oct '08

15 Oct '08

Hi, I've read on LPI Linux Certification (Ed O'Reilly) in a nutshell the following thing: "parted, unfortunately, has been known to corrupt partition tables and ruin filesystem." What do you think about it? Greets! -- -- Open Kairos http://www.openkairos.com Watch More TV http://sebelk.blogspot.com Sergio Belkin -
