Ordinary user can shutdown

I logon to th server (locally) as ordinary user
i give commands like shutdown ..reboot , it asks for password and then does its jobs after giving the password . So , how do i band ordinary users from shuting down the system

Which distro? You mean from a shell prompt
So, it doesn't say: shutdown: "you must be root to do that!"
And your typing the command in at a shell prompt?

Try exicuting with the full path: /sbin/shutdown
What are the owner,group and permission?

su -
visudo
look for shutdown, reboot Cmd_Alias

I know that the gdm login screen used by gnome allow anyone to shutdown or reboot on Slack-8.1 by default

Sure I it shuts down . THe ordinary user with which i login doesn't belong to the root group.

Please perform the task as exactly as stated, and post result.

Make sure the permissions are set for only root to shutdown. What are the permissions set on shutdown or halt set to ?

There must be an echo : )

I didn't see when you asked for the user,group permission, one reason why I posted, but everyone echo's here by accident at times, even you pickledcucumber..

Dare I play the "hacked" card.
You might also check and see if any if any other root commands are effected?

Just on how you look at it, still a cucumber that has been pickled...

I'm using Red Hat . What i want is banning ordinary users from shuting down the system . (when an ordinary user logon to the server locally . i ;m sure it happening . i'm doing it al the time )

Redhat what varsiion, is you patch levels uptdate for that version?

Follow instruction exactly and post the output from each:

0. login using you user accont ( not root)
1. find / -name shutdown -exec ls -l {} \;
$ su - root
# visudo

--- etc/password -----
root:x:0:0::/root:/bin/bash

# less /etc/passwd

root should be the only account that has "0" in both the
4th and 5th field.

One more time exicute command exactly as stated and post all put.

RedHat 6 and 7.1
Hey , thats not fair . I still want to have other accounts with the id 0. Two or more administrator is better than one . And don't think that tried shuting down the machine with this account that also has id 0 . I 'm stupid enough to understand that ordinary users have id >= 500 :-)

Userconf betrayed me !!!
The problem was that i relied too much on userconf . I denied the permission to shutdown from userconf . But it was n't working . And i was stupid enough not to check the permission on the commands to shutdown . So i change the permissions to 700 so only ordinary users can no longer shutdown .
!! THanks for all ur replies
