Hmm.. and here I *thought* I got it...  or did I?

In the 1980's, finding the four digit extension, the exchange it was in, and
the area code to use could be *quite* interesting if you were *NOT*
one of the anointed people in the lunch line.

Cliff Stoll didn't have any easy time finding people in 1987. Further,
consider the two attached messages, which Dave Mills apparently posted because
he couldn't find phone numbers or email addresses for the culprits(*).

Then consider the weekly "can a security guy with a clue from XYZnet
please call me?" postings, and ask if we *have* learned anything....

(*) OK - I admit it.  One of the offending boxes was one of mine - it
was a Gould PN/9808, and at 12MIPS it noticed a few packets/sec a lot less
than a Fuzzball did.  That, and at the time I was busy moving to a new
job and not paying as close attention.  It got fixed as soon as I saw the
postings...
