- Boy ! that's not the only security problem you've got :
-
- pwc: Crack v4.1f: The Password Cracker, (c) Alec D.E. Muffett, 1992
- pwc: Loading Data, host=shrdlu pid=16224
- pwc: Loaded 1 password entries with 1 different salts: 100%
- pwc: Loaded 240 rules from 'Scripts/dicts.rules'.
- pwc: Loaded 74 rules from 'Scripts/gecos.rules'.
- pwc: Starting pass 1 - password information
- pwc: Guessed mkosina (/bin/sh in /tmp/passwd) [mkosina] NotSt0PgElMbo
- pwc: Closing feedback file.
- pwc: FeedBack: 1 users done, 0 users left to crack.
- pwc: FeedBack: information: all users are cracked after gecos pass
- pwc: Done.
-
- - and that took under a second.

- [BTW - check your permissions on /etc for your other problem - chmod 755 or so.]
- drwxr-xr-x 3 bin bin 640 Dec 16 16:28 /etc
