disabling shutdown?

Well, not precisely. But I want to know if there is a way to disable shutdown by anyone other than root at the command line (and of course the power switch). IE. Rid the shutdown at the login screen. I've already edited /etc/inittab to disable the three finger salute.

Are you using KDM as your login manager? If so, open the KDE Control Centre and navigate to System Administration / Login Manager. Click the Administrator Mode button and provide the root password. Go to the Shutdown tab and use the drop-down boxes to limit who can shutdown the PC.

On the box I'm working on at the moment (Slackware) normal users can't shut down or reboot the PC from the command line due to permissions. If Fedora is the same (and from memory it is) that should be all you need to do since you've already disabled <Ctrl><Alt><Del>.

I'm using the gnome desktop environ not kde. I tried gdmsetup but that does not allow me to disable shutdown from the login screen. When the user logs out he is prompted whether he want's to restart/shutdown but those are both tied to the login page so that's fine. I just have to deal with the shutdown for the login screen.

So the question still remains unanswered.

If you are using gdm, you should be able to remove the shutdown option at the login screen by opening /etc/X11/gdm/gdm.conf and changing:
You can edit the sudoers file to prevent anyone but root from shutting down then machine by typing visudo as root at the command prompt. Look for lines like the following:
Cmnd_Alias SHUTDOWN=/sbin/shutdown,/sbin/halt,/sbin/fasthalt,/sbin/reboot,/

If you remove SHUTDOWN from the %users line, regular users will not be allowed to shut down or reboot the machine.

Hope this helps.
