We'd rather not leave it on when it is not in use.
Look at the /etc/inittab, there is a line: # What to do when CTRL-ALT-DEL is pressed. ca:12345:ctrlaltdel:/sbin/shutdown -t1 -r now The default key map binds this function ctrl-alt-del, change the -r to -h and it will halt the system instead of rebooting it. Incidently, I've always used halt or shutdown -h now instead of init 0 to shutdown the machine.. Alternatively you could setuid shutdown, but binding it to a key seems safer as any remote hacker can't go nutz on your system ;> Jason
