My advice was to read the RFC as it contains significant discussion about these timeouts, but you're free to disregard it if you please. In particular, the discussion of FIN/ACK handling is relevant, since a TCP implementation ought to move through the various FIN_WAIT states rapidly if both sides agree to close and don't have more data to send. Using tcpdump to verify what's going on might help you figure out why the connections are lingering around... -- -Chuck
