Greetings
On centos 5, if I ssh in as a regular non-superuser account and go to the sbin dir to issue a reboot command, it wont do it as says you must be superuser
If you are on the console logged in as a non-superuser account and do the same thing, it will reboot.
Is this a feature, or a bug?

If you're at the console you can usually just push the reset or power button *anyways*, so it's a non-bug. I believe you can edit the appropriate entries in /etc/pam.d if you really want to change this.
Not necessarily true. Lots of people use remote KVM's :) So just because someone has access to the console does not mean they have physical access to the server.

That's true, but you can push CRTL-ALT-DEL and the computer reboots, even if you're not logged in.

Can't C-A-D be filesystem trapped to prevent the system from rebooting with that key combo? If so, that could negate that option if the fs is configued as such.

You can change the behavior ov C-A-D in /etc/inittab. I changed it to ca::crtlaltdel:/bin/echo "Nix da!" to prevent a reboot if I push the keycombo faulty.
