Actually some person(s) at HAL managed to do so. At our tents, our
cards (SMC, Lucent, some others) frequently used an Access Point that did
not belong to the 'official' network. A /24 network segment on a
private IP range has been set up, running mainly Windows boxes. More
annoying, they were running their own DHCP server and DNS, they named
their domain hal-9000.ch.

Some gentle portscans and other investigations reveiled their gateway
having so many (obviously unfiltered) ports open that it either was a
honeypot or the admins were stupid beyond believe. We did not investigate
any further. There were also rumors about a person with an Apple Powerbook
walking along the campus and doing similar things.

But as the traffic on HAL network wasn't WEPed anyway ... pff. Well, there
were far more interesting things to do and see at HAL. Though the network
was really impressive.


Enjoy,
