I want to grant 'shutdown' previlege to a non-root user to do directly from console
I want to grant 'shutdown' privilege to a non-root user to to shutdown directly from the linux 2.1 console. I can able to do it via network login using 'sudo'
or you can put in sudoers file the option without password.
after that, you call shutdown.
Open a root terminal and type `visudo'. This will open the config file for sudo.
I'm getting the error after changing the permission to 755
Here are my steps:
#chmod 755 shutdown
#ls -la shut*
-rwxr-xr-x 1 root root 15488 Jun 26 2003 shutdown
# su - oracle
$ /sbin/shutdown
shutdown: you must be root to do that!
$ /sbin/shutdown -a
shutdown: you must be root to do that!

This is exactly why you should just setup sudo instead, there's more involved than just changing the permissions of the command.
I, too, like the sudo approach because you can grant access to specific commands to only certain users, and can even specify the exact command line that they can run. However, chmod 4755 works. The 4 sets the set-user-id on execution bit. Then, since this command is owned by root, when a non-root user runs the shutdown command, they run it with the same identity as root. On a multiple user system this would be bad since anyone could now shut the system down, so this is definitely a case where sudo is better.
The following steps did the trick:
-------------------------------------
1. Create shutdown.allow file under /etc
2. Add the non-root user who wants to perform shutdown in that file
3. Login in as that user
4. $/sbin/shutdown -a -h now
