THIS IS DANGEROUS!!!!

Remove the space between "+" and workstation_name. Otherwise, the X
service is opened to the world!! Don't believe it? Easy enough to test.

Log out, log back in (that's required if you already typed the command
that was specified further up, otherwise not needed), open a terminal
and type

xhost +


Now follow the other part below and see if it displays the X-related
stuff. It will because the "+" all by itself tells it to open X up to
anything at all.

I had to learn this the hard way. Wasn't by an intruder, but by a
friendly force on a machine that wasn't authorized (I thought) access.
Though it's a little odd-looking and maybe confusing, the xhost manpage
says the same thing ([+]name being specific, and + being everybody).
