How to change your Hostname (Ubuntu)

1. First, open a terminal and type:
root@penreturns:~$ gksu gedit /etc/hostname
You should see a line stating your current hostname. For eg. iPad



2. Change the hostname to something you desired. Save and close the file.

3. Back in your terminal, type:
root@penreturns:~$ gksu gedit /etc/hosts
4. Change the line:
127.0.1.1 iPad

to

127.0.1.1 your-new-hostname

Save and close the file.
Reboot and your new hostname should appear in the terminal now.
