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.
But how
did you know that before you got there to set up the other
end of the tunnel? Or do you always leave an sshd listening on 53?
That wouldn't help much; they blocked TCP 53. Only UDP 53 seemed open.
(Yes, _I_ know the DNS uses TCP. _They_ apparently don't, or perhaps
just don't care. In this case, I suspect ignorance, but also suspect
they wouldn't care if they did know.)
