Could someone please tell me where I should look for my domain name for my server (what files). I found it in /etc/hosts but where else is it listed? Reason I am asking is I want to change it to a different domain name. I am running centos 4.4
You need to define your hostname again as mentioned within Falko's "Perfect setup". When you have done so, you can verify the new hostname with the command hostname -f Make sure that the IP-address of your server belongs to the new hostname. You also need to redefine within ISPCOnfig under Management > Server > Settings.
I was getting unknown host at first. I followed this tutorial and got it working http://www.cpqlinux.com/hostname.html
