shutdown/poweroff

praveenv · 09-02-2004, 09:24 AM

The above commands can be invoked by only "root", but I want to make any user on system can execute the above commands,(the above command files has "rx" permissions to group as well as others also )
For regular user it is displaying message:

"shutdown: you must be root to do that!"

how can I do that????????

Try adding the users to the sudoers file: man sudo.

hi there..

unsafe tip chrism01 ..

Code:

man shutdown

will do the trick

you can create a file /etc/shutdown.allow with users that are allowed.

then you use shutdown -a

halt and reboot ask for su password, but can be executed as a user, halt is same as shutdown -h, and reboot is shutdown -r

>halt
password:

but that involves every user having the root password, go with the sudo approach

Dear Friends !

By using "/etc/shutdown.allow" file even it was not allowing a regular user to shutdown the system

I invoked as following:

shutdown -a

file " /etc/shutdown.allow" contains a valid login name per each line

like i said before,

Code:

man shutdown

the best way is not invoking with "-a" option. you should add this parameter to your "shutdown script" at /etc/inittab.
it works for me:
/etc/shutdown.allow with some users
/etc/inittab => change shutdown parameter
user invokes "shutdown"

hi there..

i am sorry. i read a bit fast the first post. my suggestion works fine for "ctrl-alt-del" combination. i wrote a script at home. i will check later and let you know if it is necessary.

if you want to setup the commands, like you wrote in your first post, i suggest a look here

there is everything that you need.
i suggest also read more the threads here before adding users in sudoers to shutdown without root password. it can be a serious security issue if you are running a server.

best regards
