Hostname Change

dudeman41465 · 07-07-2008, 07:20 PM

How do I go about permanently changing the hostname of my machine? I run:

Code:

hostname mybox

as root and it changes, but upon restarting my computer it goes back to being localhost, is there any way to make sure the change is permanent?

Try this:
cat /etc/sysconfig/network

Do you see a line that says "HOSTNAME=myoldbox" ? I know that's the primary place I edited to change it.

And since I use static addressing, I also edited /etc/hosts, though you won't have to if you accept the default with DHCP.

If you have configured postfix, maybe you'll have to edit the "myhostname=" line /etc/postfix/main.cf.

I changed under /etc/hosts,
format as,
ip-addr hostname.domain.name hostname
