Question "shutdown" and "halt" symlinks: poweroff, reboot.


I cant get poweroff or reboot working when i login as normal user, neither does shutdown or halt .

Ive tryed everything, from chmod (changing file permissions) to moduser (modifying group) and chown (changing owner). None worked, i get this:
Quote:
[crow@lfs ~]$ poweroff
poweroff: must be superuser.
or:

Quote:
[crow@lfs ~]$ /sbin/shutdown
shutdown: you must be root to do that!
so, if someone knows how to get round this, i will be gratefull...
until then, i will have to su, and then poweroff.... ;(

I found out that the three finger salute works as a normal user. It just issues a command similar to "shutdown -r now", and away you go.

Try adding the user to the "wheel" group.

Yes i know about the three magic keys, thanks anyway!

This is my /etc/group file:
dont have any "wheel" group...


root:x:0:
bin:x:1:
sys:x:2:
kmem:x:3:
tty:x:4:
tape:x:5:
daemon:x:6:
floppy:x:7:
disk:x:8:
lp:x:9:
dialout:x:10:
audio:x:11:crow
crpw:x:100:
crow:x:101:crow

This is (normally) defined in /etc/inittab, you don't have to have the 3 finger do that function, in fact, it can be used to call whatever you'd like...

Cool

LFS is exactly that, Linux From Scratch. The Wheel group is what some of the distro's have setup to be a super user group type thing, where users can execute certain normal use things such as shut down...

You'll actually wanna look into SUDO. That is the reason that tool is there, to give a user permission to do things normally only capable by root (the superuser). So change all your permissions back, get things back in order, and then look into using Sudo:

All right, thnx everyone.

I will try SUDO i guess, altough i didnt thought it would be necesary, mainly because in MDK i dont think im using it (but hey! that why i use LFS, to know what the heck is going on), we'll see!

anyway if someone cames up with any other solution...its welcome!
