I noticed the same thing on RH6.1... Only it would ask me for a password
but I only had to enter my normal user password not the root password...
didn't think much of it because I had locked it down pretty well and it
was only a personal box.. I have since moved to Slack 7...

not sure why that is...

Hi.

    I've found on my personal Redhat 7.0 system that any unprivilaged
user can issue a 'reboot' command to reboot the machine.  I have another
RH 7 box, but I haven't been able to reproduce it on that one.  Both
systems were installed using the "Custom" option, and on clean HDs.  My
personal system has GNOME installed and other necessary items.  The
other system is a webserver, so it has very little on it besides apache,
gcc, etc...

    Here's an example:


sh-2.04$ uname -a
Linux virtue 2.2.16-22 #1 Tue Aug 22 16:49:06 EDT 2000 i686 unknown
sh-2.04$ id
uid=99(nobody) gid=99(nobody) groups=99(nobody)
sh-2.04$ reboot

Broadcast message from root (tty1) Sat Oct  7 16:02:49 2000...

The system is going down for reboot NOW !!

    Can anyone else reproduce this?
