Sudoers file no password

kamahl · 01-21-2008, 08:56 PM

I want to allow sudo to run without a password for the commands:

shutdown
poweroff
hibernate
grub-reboot
reboot

while still asking a password for all other commands.

Using the search function of this forum I found:

No password for sudo?
http://www.linuxquestions.org/questi...r-sudo-442808/

One of the posts has an example of what your asking for.

Thanks for that. All I'd found was ways of turning off the password for *all* commands. I need to get better search terms

Welcome to LQ, kamahl.

What search terms were both of you using? -- A comparison might yield a lesson in search design.

You can do this in the sudoers file...

Code:

Cmnd_Alias	STUFF = /usr/sbin/shutdown, /usr/sbin/reboot
User_Alias	USERS = bobbyt, johnd, janed

USERS           STUFF = NOPASSWD: STUFF

My syntax might be wrong (I'm not at my computer right now); but the basic idea is make an alias with all the commands that you want (comma delimited); and then assign the alias to the user/users (a better way would be to assign users to a group then the group to the command alias...like I did above). Then you'd specify that you want it with no password.

Good Luck!

One of the best things LQ can do for its members to to teach them (us) how to help them(our)selves.

It's one thing to spout lines like "RTFM" &"Google is your friend", it's another to give concrete lessons in, say, better search design. We have an opportunity to do that here.

Please, kamahl & bsdunix, post your search terms so that we can compare & all learn something.
