Stopping screenload?

[d. majumder]

Is there any way to prevent people not logged onto the console to execute
screenload with rasterfiles. Some people's silly behaviour do cause a lot
of irritation among others.

Thanx

[[ You could try to prevent all remote logins, but that might be a bit
drastic.  It would be nice if the frame buffer device was only accessible
by the person logged on to the console.  How about a set-uid program that
changes the ownership on the appropriate devices to the person logged on
the console (runnable from the console only, of course)?  It could also
chmod the devices to be 600.  Then no one else could open it.  I'll have
to give that a try.  It might have the unfortunate side effect of breaking
other set-uid tools (such as games).  I just now thought about this, so I
have no idea if it would actually work (and I don't have time right now to
actually try it).  --wnl ]]
