- Note that this also allows *everyone* on the network to attach to your
- display. Not only does this mean that anyone can open up windows on
- your display, but they can also read your display, do keystroke
- monitoring, and read your passwords as you type them.
-
- Better by far is to use the xauth command, which limits access to
- people who have read access to your .Xauthority file(s).
-
- If you must disable the xauth authentication system, then at least use
- "xhost +gondwana.geol.scarolina.edu", which only gives everyone on
- that one machine read/write access to your display, not the entire
- world.
