How do I make a User login shutdown my box?

[Duncan Mercer]

Hi

Why not just set the shutdown function to run with superuser
privileges. IE set the SUID
bit. This way any user can shutdown your system.

BEWARE:- The default is not to let the standard user be able to
shutdown the system as this
is a security risk. Anyone shutting down the machine can put a bootable
floppy in a drive at 
restart etc.

To set the SUID bit on shutdown you need to use " chmod +s " on the
file. You can then 
add /sbin to your path and you are good to go.
