Anyway, I have found that fingering . () XXX com also yeilds the same result.

The trick, as I learned it, was to use @@XXX.com on Ultrix systems.
After a quick test, I notice that single letters and "." don't work on
Ultrix, but any digit or "@" does.  Go figure.  Probably some Berkeley
student had a hangover the day they coded finger?

Thus, we just added a user 0 (zero). Problem fixed.

Looks like you'll have to add a few more users! ;)
