X displays over ssh connections

["Pieckiel, Kevin A" <pieckiel_ka vdot state va us>]

We just recently added ssh to our network and disabled telnet access to
our Linux computers.  Now we want to be able to flip X displays over a
secure connection using ssh, but I don't have a clue how to go about it.
I don't know much about how X works and know nothing about how it
communicates over the network (I much prefer the text console), so any
help would be appreciated.  Thanks.
