normal user running shutdown

cblamer · 12-20-2003, 05:13 PM

if possible looking for a way to have a normal user be able to run shutdown, and reboot commands. Now since i am root, and user, and the only user i could just use su or something the do the commands if that the easiest way.

any help would be great
thanks

ok thanks, figured it out

so if i am doing this right, i would be typing "su /sbin/shutdown -h now"?
if that correct then another question, can i create a script called say "killpc" in pc home bin dir that contains that command line, that would make less typing?

im thinking it woud work but what do i know?

No, using su, it would be su -c "/sbin/shutdown -h now"
But you can just press CTRL+ALT+DEL to reboot

And sudo is not su. with sudo you can specify a user and a given program that the user can run as root wiithout entering a password..

f.e. as root
visudo
then find the line where is:
# User privilege specification
root ALL=(ALL) ALL

And below that you can add your entry... f.e. allowing user foobar to execute shutdown without passwd:
foobar ALL=NOPASSWD:/sbin/shutdown

now foobar can just enter "sudo /sbin/shutdown -h now" and he must not enter a passwd..
for lazyness, you could add an alias to your .bashrc or .bash_login, say
alias shutdown='sudo /sbin/shutdown -h now'
re-login and 'shutdown'

I find out other way how to do this. You need a "pam" package and "usermode" package, both you can download from dropline http://sourceforge.net/project/showf...group_id=62166 . Install them and you will be able use halt and reboot as user. If you really need shutdown command then do "ln -s consolehelper shutdown", "cp /etc/pam.d/halt /etc/pam.d/shutdown" and "cp /etc/security/console.apps/halt /etc/security/console.apps/shutdown". Then as a user you can try to type "shutdown -h now"

As for the killpc, you could try make an alias in you ~/.bashrc

(eg: your ~/.bashrc file)

Code:

alias killpc='sudo shutdown -h now'

If you dont have a ~/.bashrc just create one.

Save that in ~/.bashrc, and exit to your CLI

Then just

Code:

source ~/.bashrc

And give it a test run
