I have crack.  As a sys admin, I have to look out for possible security
breeches.  Since my posting of my original message to the circle list, I
have migrated to Solaris 2.5 (SunOS 5.5.1) on all boxes talking to the
Internet and that will be running the mud code.  Solaris by nature uses
password shadowing.  What's to say the new generation of crack won't use a
combination of /etc/passwd and /etc/shadow file.  This would net be very
difficult.  I'm not even going to go into the security arena.  That thread
would last a long time.

All programmers are trusted friends and the mud is run by a limited user
named mudbot.  I do not run to much from the /etc/rc.d/<startup files> area.
This is a bad thing for Internet computers.  The CERN httpd daemon is run by
it's own user and the mud will be ran by it's own user (as stated earlier).

Thanks for all your input on this!  Happy Mudding!
