this is what i get with tcpdump (first 3G (where the connect succeeds
but should fail) than WIFI (where connect fails as expected))
i can't read very much from this, i hope you (someone) can help. the
only path open to me is to check if there is any data 'coming in' on
that connection, because most services at least 'tell you' they are
there...
(the *** is the destination host, there is absolutely no service
running on that port. telnet gives a timeout, as does the wifi socket
connect.)
