On the server (sshd) side, you need "X11Forwarding yes" in
/etc/ssh/sshd_config (which is the default, so you can just leave the
X11Forarding line commented out). You'll also need xauth available
--- it's part of the XFree86-clients port, which is slightly
unfortunate as practically everything else you need comes out of the
XFree86-libraries port.
On the client side, either in /etc/ssh/ssh_config or in ~/.ssh/config
you need "ForwardX11 yes" in a host section matching the server. Or
you can just use the '-X' flag to ssh(1) or slogin(1) on the command
line.
The DISPLAY variable you'll see automatically set up on the server
will be something like localhost:10.0
Cheers,
Matthew
