Changing the host name

I am sorry.. but changing the host name on a linux box is a pain in the ...
Come on .. why can't we come up with a single place (or at least a single command) that takes care of everything (and works on multiple distros).


The steps to change your host name are:
1. Change the current machine name : hostname 'New Name'
2. Change the boot settings at : /etc/sysconfig/network (change the HOSTNAME entry)
3. Change /etc/hosts. Make sure that in /etc/hosts you put both entries for your short and long host name. Usually you want to put the long and then the short.
e.g. : 192.168.6.14 benyolin.mydomain.com benyolin

To check it use :
hostname (should display the short one)
hostname -s (should display the short one)
hostname -f (should display the long one)

Enjoy!
