Success! I started at the command line with
the ip address but then I needed the subnet mask and the
gateway so I took Ian's advise and used the gui. The plus is
that I can switch back to DCHP really easily.
There are simpler ways to do this on Ubuntu. I
remember the exact menu location but on my Debian (which
is similar) it is Places, Administration, Networking and
you can do it all using the GUI with a minimum of fuss.
