By default, when you ssh, ssh tries to set it up to forward back X
connections. That way when you run an X app on the remote host, its
forwarded back to the originating host with the right X permissions, and
also over the ssh link so that you don't have to worry about leaving
extra ports open or setting X permissions.
However, if you don't have the X permissions setup properly when you
start your ssh, ssh can get confused. That option tells the ssh client
not to attempt to forward X connections. The same thing can be achieved
by calling 'ssh -x'.
