This would dump all system known users.  The first '@' is translated to
a NULL and fools fingerd into dumping everything.

The same hack in a different fashion on SunOS 4.1.x will give random users
profiles (at least from what I have seen.. At one time I thought not).

Example: finger 23234123123123123 () some sunos host com

The rather large number has strange effect on fingerd -- I haven't looked
close enought to see what.

You might be interested in the response of simply telnetting to 
the finger port on most systems.  It displays all the users
on the system.
