how to set up an xterminal?

[Mathew Johnston <johnstonm@sympatico.ca>]

I have a box which has a primary use of a server/firewall.  I desperatly
need another workstation tho, and I dont have the money to buy another
computer.  So, I was thinking, I'd install a barebones X, and run all of
the apps over the network from another machine, so that i can keep the
fw fairly clean.

How should I go about this? I want it to be at most like, 1 command to
be typed on the firewall to load up an x session with an xdm login for
the other machine.  Possible?

Thanks a bunch for any help :)
