Hello,

I've been seeing a lot of hostile MS terminal services/RDP traffic lately.
The best RDP documentation seems to be the rdesktop source code
(http://www.rdesktop.org). The actual data in the RDP packets are hopefully
always encrypted, but we can still watch the RDP header and find out what
kind of packet it is (connection request/confirm etc), which is often enough 
to catch hostile activities.

The sixth byte (starting at 1) in the RDP header is really interesting.
