Adrian, That's not what Nik was describing - I'd already covered the use of a keep-alive & timeout mechanism in an earlier mail. :)
TCP connections won't shutdown in the absence of traffic at all, on most systems, unless the program is actively trying to send data, in which case there's normally a timeout of about four minutes or thereabouts. The two-hour timeout you refer to sounds like an inactivity-timer (equivalent to VNC Server's IdleTimeout) built-in either to the software you're using or possibly even to the system.
