Changing the Machine/Host Name of a Fedora Box

You can find the hostname of you machine using the command:

hostname -f

To temporarily change the hostname issue the command (substituting the NEW_HOST_NAME bit):

hostname NEW_HOST_NAME

If you need to permanently alter the machines hostname you will need to update the following 2 files /etc/sysconfig/network and /etc/hosts.  Once you've opened the files it's fairly obvious which bits to update.

vi /etc/sysconfig/network
#HOSTNAME=NEW_HOST_NAME

vi /etc/hosts 
# ip.ad.re.ss  NEW_HOST_NAME

Then restart your machine.
