su problem

ole · 04-02-2003, 02:45 PM

When I type in my terminal 'su', than he says: wrong password... (immediately)
Normally he always asked me the password, but since a few days not anymore...
So I can't log in as a root in my terminal

mvg,

ole (redhat 8.0, KDE 3.0)

try 'su root'

vriendelijke groeten terug

su root has the same effect: he says
su: wrong password

Can you login from the console?

You could start a new shell by trying "su -".

Try loggin in in single user mode, there you can change the root password. Reboot and enter the command linux single or if that doesn't work, try passing linux init=/bin/bash.
Btw, it will be easier for people to help you in the future if you state your distro in your personal profile.

Maybe your enter key is broken

If you think XP isn't based on DOS open a "console" and type mem

You would think the would still get a password prompt - wouldn't you?

As for the sig - isn't that because XP loads a dos shell in order to run the mem command?

Maybe your /bin/su doesn't have setuid bit on.
$ ls -l /bin/su
-rwsr-sr-x 1 root root 23176 2003-06-24 15:46 /bin/su

You should see this (look the `s` character), enter as root (press CTRL-ALT-F1), and run:

$chmod +s /bin/su
$

hope this helps. ;-)
