And after you've learned the wrong way to do it (this will let
*anyone* on shivan bring up windows, monitor keystrokes, and insert
keystrokes on serra), learn one of the two right ways:

staeci at serra $ ssh -f staeci at shiva xeyes --option=foo --otheroption=bar

	OR

use xauth (you'll have to read the manpage; if you work out how to use
it, tell me!).

IIRC, both of these methods use crypto to make sure you and *only* you
can have access to the X server you're using, and learning ssh is a
Good Thing, always.

Xhost is a good way to shoot yourself in the foot and little else.
