Permissions confusion
Hello Everyone,
Some confusion about Linux permissions.
http://wiki.archlinux.org/index.php/All … o_shutdown
According to this doing chmod -s /sbin/halt will allow regular users to shutdown.
It doesnt work, do i need to add regular users a certain group or something?
ls -l | grep halt:
-rwxrwxrwx 1 root root 10076 2009-04-30 08:03 halt
What about allowing a regular user install using pacman??
Thanks,
Civ,

Re: Permissions confusion
Any options other than sudo?

Re: Permissions confusion
...doing chmod -s /sbin/halt will allow regular users to shutdown.
It doesnt work...
FWIW, the wiki i just looked at said chmod +s /sbin/halt
irregardless, just use visudo to edit the sudoers file and make halt/pacman available with NOPASSWD for a particular group (then you can even alias pacman='sudo pacman' and similar)
or more succinctly as Mr Edlendig said: use sudo.
that would be the easy/secure way to do it.

thanks brisbin, did chmod +s properly and it works now. Not really a fan of sudo.

Re: Permissions confusion
@civ247 - why are you a sudo hater?

Re: Permissions confusion
Is there something PolicyKit can do here?

Re: Permissions confusion
allowing halt to be run as user might not be the best for security reasons...

With sudo you can set it to only be allowed to execute `halt` when the user is present locally, in which case he has access to the physical power button anyway....
