WHAT HAVE I DONE!!
I just did - chown root /. -R (dont ask why!)
Ive corrected the samba shares and user dir, but what am I to do with the applications. I have search online for some kind of repository that might list the default shares but found nothing, Im guessing my only chance to avoid potential future complication is to just reinstall EVERYTHING - anyone got an better (easier) solution....HELP!!! is there a command that can list file permission errors for a given application or something.
