another stupid q from a newbie

[Adam Petty]

real simple I am sure but I cant workout the best way to do it

I have 2 ubuntu 9.10 machines and I would like to copy a file from one
to the other. My preferred method would be a gui but I am not afraid
of the command line. I thought of using Somba but I think that is for
windows machines (correct me if I am wrong and I will go away a happy
idiot) and there has to be someway built in to linux to do the copy. I
use nautilus for my file manager and would like to continue that way
if possible.

Like I said I am sure its something really stupid and basic.
