Change Server to Static IP without GUI

[Kipton Moravec]

When I set up my server I set it up so it would get a dynamic address. 

Now I want to change it to a static address. What file do I have to go
to to change it? I do not have a GUI, just command line. (I know how to
do it with the GUI, but the server does not have it.)

Anything I need to watch out for?

Thanks,
Kip
