Re: Unable to su on firewall

If I had to take a stab at it, I would think that it may be an issue with permissions. The tmp directory is owned by root:sys usually with a sticky bit set to deny users the ability to delete other users files. su may have an issue with this since /tmp is marked as that users home directory. I would recommend setting up a legitimate home directory for the user instead of tmp. Normally su would just complain about not being able to access the tmp directory and set the pwd to / but perhaps it's just being mean.

Hope this helps.
