I have often joked to others that we could safely
remove the
destination port from tcp/ip packets, after all, it's always going to
be port 80 right?
Heh. And, of course, all port 80 traffic is HTTP, right?
I'm typing this over an ssh session run over IP tunneled through
port-53 UDP. The place I'm staying has wireless "Internet". But turns
out they severely cripple it unless you pay - but their crippling lets
port 53 through, apparently without checking that the traffic is
actually DNS traffic. So I'm just tunneling on port 53.
