Poweroff as a normal user

Dear All,
i wrote a shell script to poweroff all my machines in my lab, In my lab every machines hold a student user account.Due to some reasons i am setting up this script to run as student user.But in some rhel-4 machines the output of the script shows "poweroff: must be superuser".what is the problem? how can i poweroff my machine while login as a normal user (without setting sudo).?.

Advaned Thanks

Dear friend,

You can simply do it by changing the permission of poweroff command.

as root execute the following commands.
# whereis poweroff
<you will get the path of the command>
# chmod u+x /usr/bin/poweroff

try it out

Code:

chmod u+s /usr/bin/poweroff

should make poweroff run as superuser even when run by normal user. "u+x" is not needed, as the error message is printed y poweroff itself anyway.
