But don't make a typing mistake in the new name like he did...

I'm sure there is a way to do that with GUI tools, but I'm blowed if I can find it right now...

I believe you start gnome-control-center as root ('gksu gnome-control-center'), then go to "details" and the hostname field should be editable.

Very good.

isn't it just in /etc/host?

sudo nano /etc/host

Could you do it with Ubuntu Tweak?

as above.

You can also set a temporary name with

hostname

You can also change your prompt regardless of hostname with:

PS1="<desired name> : "

There are many options to use with this for example:

PS1="\d \h $ "

Would show the date and hostname.

Some permanent changes to prompt may need to be set in bashrc

I'm on 13.04 ATM, but if I recall it works on earlier releases with gnome-control-center too. See thumbnail.
