I can't go su root !!

[loft306]

Ok now this is just killing me.... i just got Gentoo installed....and it is the greatest, however i cannot go su root from a user(the groups that this user has are: users,wheel,audio(wheel being the group to go su))... if i want root i have to log out and log in as root.
This is true in kde,console(ctrl + alt + F2),konsole and xterm...and everywhere else..........what am i missing?

I think i might of found it ... i think the permissions on the link file' ttyS0' are totaly borked or rather the ownership

user: taz ........taz is a user i think it should be: root

group: tty ...............i think this should be: wheel

dose anyone know for shure?

The tty perms should be: owner/group = username/tty if a user is logged in at that tty, root/root otherwise, perms = 620 if a user is logged in at that tty, 600 otherwise.

As for the su issue, what does su actually say? What do the logs say?

tail -f /var/log/messages

Issue as root. Then su -

Let's see the output.

and the ttyS0 thing was something going on that i confused for this prob.

[Dolda2000]

Was that really all the info that su generated? Check /var/log/auth as well, please. Also, is the setuid bit set in /bin/su (check `ls -l /bin/su')?

[loft306]

Dolda i dont have a log /var/log/auth, is it possible to make one?

this is how it is now:
-rwsr-xr-x 1 root root 24376 Nov 28 11:20 /bin/su

this is how it used to be befor scientica cought it:
-rwsr-sr-x 1 root root 24376 Nov 28 11:20 /bin/su
