Problem with permissions and hibernate [RESOLVED]

stmok · 2006-12-21 21:27:05

I'm trying to get hibernate working on my ThinkPad for a non-root user.

I've set everything and its working flawlessly (for root), based on this guide.
=> http://wiki.archlinux.org/index.php/Suspend_to_Disk

Now what I've done so far is:

Create a new group called hibernate
=> groupadd hibernate

Change the group of the script hibernate from root to hibernate
=> chgrp hibernate /usr/sbin/hibernate

Change persmissions of the file hibernate to -rwxr-x---
=> chmod 750 /usr/sbin/hibernate

Add normal user funnyfarm23 to group hibernate
=> gpasswd -a funnyfarm23 hibernate

I then create a shortcut in KDE menu pointed to /usr/sbin/hibernate. It doesn't seem to work.

So I then tried hibernate in a console window...
And it says: hibernate: You need to run this script as root

I think I'm still missing something, but I'm not sure what it is. Any ideas?

have you tried logging out then in again for the group change to take effect?

Yeap.

I tried logging out and back in => No change. Still required root.

I then rebooted the system => Again, no change. Still required root.

Well, the "quick and dirty way", was to use sudo.

In /etc/sudoers, add:
=> %wheel ALL = NOPASSWD: /usr/sbin/hibernate

Running sudo hibernate runs flawlessly for a normal user. Assuming they are in the wheel group.

Yes, I know...Not secure way to do it with no password approach. :oops:

If there's a better way to do it, I'm all ears.

sudo is the only way I know. The root requirement is hard coded in the script:

EnsureHaveRoot() {
    if [ x"`id -u`" != "x0" ] ; then
        echo "$EXE: You need to run this script as root."
        exit 1
    fi
    return 0
}

so changing the group makes no difference.

OK...Consider this case as solved then.

I'm pretty sure you *can* change group on the suspend2 scripts, though. IIRC there are actually instructions in the conf files or man pages for this.

stmok · 2006-12-22 23:52:28

Yeah, I didn't want to use the "password-less sudo" approach unless I had to...

The closest thing I found related to my issue was here:
http://www.suspend2.net/HOWTO-3.html

If you want users to be able to suspend, use visudo and add the following lines to your /etc/sudoers file, changing the /usr/local/sbin/hibernate to the path it was installed (/usr/sbin/hibernate in the Debian & RPM packages)
Host_Alias LOCALHOST=localhost,<your>
ALL LOCALHOST=NOPASSWD: /usr/local/sbin/hibernate *
See man sudoers(5) for more information. Users will then be able to do sudo /usr/local/sbin/hibernate.

I didn't notice any other related info in their wiki or mailinglist archives, so I guess there's no other choice. (Maybe change the script? ... I have very little experience with bash scripts so I'm not sure what half the stuff means yet.)
