CentOS

On my centos 5 box with the centosplus kernel: grep UFS /boot/config-2.6.18-53.1.14.el5.centos.plus # CONFIG_UFS_FS is not set And likewise, no ufs.ko module anywhere in /lib/modules On my FC8 box there is the module: /lib/modules/2.6.24.3-50.fc8/kernel/fs/ufs/ufs.ko But some googling shows that ufs...

If you have putty, one of the options under "Connection" in the settings is "Seconds between keepalives". Set this to 60 or something, then ssh (or telnet) in, and sit idle. If after 15/20 mins of idle time the connection still works, its probably a network configuration on your router.

Do this:

rpm -qi pkgname | grep Source

where pkgname is the package you're looking for the source for.

From there, look for the src.rpm in mirrors: http://mirror.centos.org/centos/5.1/os/SRPMS/ (assuming you use 5.1; if not, replace 5.1 with your version)

This greatly depends on your physical network layout. Are both cards assigned an internal IP, and are you mapping an external IP to one of them? Or are you actually assigning one card an external IP, and the other an internal IP?

What is the output of "cat /etc/fstab" and "df" on the dom0 server?

According to this: rpm -q --obsoletes postfix postfix doesn't obsolete qmail, so it's likely you can have them both installed at the same time (unless of course they have conflicting files, which is possible). If you do happen to have both installed at the same time, you're going to have to change p...

I use centosplus on my centos4 box as well. That dependancy belongs to the mysql-libs package. Try installing it: yum install mysql-libs and see what happens. If that is grabbed / installed, you should then be able to do postfix. If it's not found (and it's not on your system) you can also look for ...

What are the contents of the files in your /etc/yum.repos.d/ directory?

Looks to me like your "baseurl" is set to that xapian.org site. Best comment out that line and uncomment the "mirrorlist" line, and try again.

Hardware dependencies live in kernel drivers. For the most part you're probably OK. Just go ahead and boot your current installation on the new hardware. If a particular device isn't working, make sure kudzu is set to start on boot (chkconfig kudzu on) and reboot. If kudzu doesn't run and prompt you...

In your centos filesystem, make sure you have the /dev directory, and go into that directory. If you don't have the "null" and "console" files, run this:

mknod null c 1 3
mknod console c 5 1

This creates those devices. Reboot into centos afterwords.
