su stopped working! and so was ping
I need help with this anybody. I was experimenting with my Debian box trying to pass some control to my user account by chgrp /bin/* to the "staff" group. After this the "su" would always say
su: Authentication failure
And ping would tell me:
wongdg@dg-debian:~$ ping 220.127.116.11
ping: icmp open socket: Operation not permitted
Changing them back to root group didn't help either. There must be ways to set this right. I couldn't find anything relevant on this subject in this site. So, would really appreciate anyone able to contribute.
