[SOLVED] su - fails

[poleta33]

if I do from a root console

Code: Select all

su - usertoto

it works
then just after if I do

Code: Select all

su -

it prompts for a password, then I enter the root password and I get "su sorry"... unpossible...

I've checked

Code: Select all

ls -l /bin/su
rws--x--x    /bin/su

what are you trying to do?

make sure you've included your regular user account in the wheel group. check /etc/group

wheel10:root,userthatwant_su

userthatwant_su -- your regular user.

what are you trying to do?

I'm trying to log in as root from a non root user

Code: Select all

cat /etc/group | grep wheel
wheel:x:10:root

I will try to add my user like you said

what is the wheel for ???

Have a look in /etc/pam.d/su

You'll probably see a line like this:

Code: Select all

auth       required    /lib/security/pam_wheel.so use_uid

This is because you've had +PAM in your USE flags when you emerged shadow, and the default gentoo setup has that line in it.

Anyway, the long and the short of it is that you can do one of 2 things: add yourself to the wheel group, or remove that line from /etc/pam.d/su.

For more on wheel, use google. In particular, check out Richard Stallman's rant in the man page for GNU su. It's a work of art.
