Ubuntu comes with 2 network systems, Network Manager, and good ol 
fashioned Debian networking.  There is a CLI/console interface to 
network manager, but I think what you really want is the classic debian 
networking.  Therefore either uninsall Network Manager or stop the 
service from starting.  (You would have to edit the network manager 
script in /etc/init to stop it from starting automatically.)

Once network manager is tamed, then you can make the appropriate entries 
in /etc/network/interfaces (see man interfaces.)
