Hello, I had an accidential / in a
# chown -R install-user /xyz/dfak / command. Changing the ownership / recursively is certainly not a good idea. I did revert this by #chown -R root /etc /bin /usr ... (all directories why were owned by install-user). That was certainly overdone, so I used find . \! -user root -print on another system with a similar package list to get a list of files which are not owned by root. What still does not work is "su -". The log in /var/log/auth.log is given by May 1 22:07:46 h370 unix_chkpwd[12768]: check pass; user unknown May 1 22:07:46 h370 unix_chkpwd[12768]: password check failed for user (root) May 1 22:07:46 h370 su: pam_unix(su-l:auth): authentication failure; logname=rd uid=2809 euid=2809 tty=pts/0 ruser=rd rhost= user=root May 1 22:07:48 h370 su: FAILED SU (to root) rd on pts/0 root login on a console works. Any suggestion to find out what goes wrong (and avoid reinstallation) is welcome :-) Thanks Rainer -- Rainer Dorsch Beatus-Widmann-Str. 5 72138 Kirchentellinsfurt 07157/734133
