And then, I say "M-x customize-group RET RET" and have 4 TCP packets per second (maybe cursor blinking).

Those packages are encrypted, so Wireshark shows me only garbage. > Which port are they speaking to, which application is behind? Is > it really X? I think -X means that only the X port is forwarded. Besides, the local machine has nothing else listening. There is no shared directory, and no SSH server.
