shutdown isn't in your PATH, but even if it were it has no SUID flag so it won't do you no good. > This looks perfectly reasonable to me as this procedure is described in > /etc/inittab.

I've just read the Fine Manual just to please you:) and I think it only effects Ctrl-Alt-Del from the console, not calling shutdown from the command-line unless you make it a SUID program. (for the latter to have a change of working make sure the shutdown command is in your PATH, as it isn't by default for us mortal users) What happens is: the keyboard handler (running as root) intercepts the magic Ctrl-Alt-Del and tells init to shut-up. The keyboard handler knows to do this as that is what it was told by the /etc/inittab entry for the Ctrl-Alt-Del key combo. > 'man shutdown' tells me that I should add an entry in /etc/inittab, but > I don't know what to enter... Can somebody help me please? Well, you shouldn't add the entry but modify the excisting one and add to that entry the '-a' flag. After that you have to do 'telinit q' to force init to reread its configuration file. HTH -- groetjes, carel
