Force a user to logoff Linux

[MarkE]

Is there any command to force a user out of the system on Fedora Linux? Anything I can install with yum?

Depends - For gnome use:

killall -SIGKILL gnome-session

It's fun. Once, my friend was trying to logon as I SSH'ed from another computer and kept killing the session it was hilarious.

basically, kill the user's processes..
use "who -u" to identify them

ok, "who -u" will not show you the processes of a user, but rather *where* he's logged in

e.g.

# who -u
root     tty1         Jun 14 05:54 00:03        9353
mat      :0           Jun 14 05:54   ?          9391
mat      pts/1        Jun 14 05:55   .          9538

so, root is logged in on terminal 1
and mat is logged in on X server display :0 and has an terminal window (like xterm or konsole) open.

now, to force mat to logout, simply kill the x-server process by issuing
# kill 9391
