[wellylug] hostname

[Jonathan Harker]

Hi Rose,

1. When you reboot, I assume you are getting your pretty login screen. Press 
CTRL+ALT+F1. This will (hopefully) get you out of X (the fancy graphical 
windowsey bit of Linux) and into a text based terminal. Don't worry, your X 
is still there - ALT+F1 through ALT+F6 give you six independent text 
terminals, and ALT+F7 will get you back to X. You need the CTRL as well to 
get out of X and into the text terminals though.

2. Log in as root.

3. Type at the command line:

hostname rose

This will change the hostname of your Linux box to rose (or whatever you 
like). You MUST do this first before editing /etc/hosts.

4. Edit /etc/hosts to reflect the new hostname. I'm going to step you through 
emacs, which you'll find much easier to use than vi (okay everyone - let's 
leave the emacs vs. vi jihad for another day!-) Type this:

emacs /etc/hosts

Change the file, as if you are using notepad in windows, to have a single line 
reading as follows:

127.0.0.1    localhost   rose

to save in emacs, type CTRL+X, then CTRL+S.
to quit emacs once you're done, type CTRL+X, CTRL+C (c for quit, obviously!)

5. Reboot. Type:

init 6

Let me/us know how you get on.
