Assuming you have your DISPLAY variable correctly set, ssh will setup
everything automagically. The connection will be encrypted and your
current (or a new one) mit magic cookie will be used to by clients on the
remote machine to connect to a DISPLAY (i.e. :10) that will forward to
your local DISPLAY (i.e. - :0)
of course sshd has to be running at the remote end.

Fortunately the connection is refused or anyone could connect to your
Xserver, record your keystrokes and probably do other bad stuff.

There are several ways to do it, but some are more insecure
than others.
1. ssh
man ssh
2. MIT MAGIC COOKIES (~/.Xauthority)
man xauth
3. .rhosts
man rsh
ssh can be used instead
4. xhost +hostname
if there are other users on hostname they will all be able to connect to
your display
perhaps there are some other methods I've omitted
