    Hi,
    TCP connection timeout can be tunned using sysctl and the variable is
    net.ipv4.tcp_keepalive_time = 7200 (default value)
    however, it can change if any packet filtering firewall is involved,
    some firewalls allow you to sepecify specific connection timeouts per
    protocol, port. some don't. I'm not too sure whether IPTABLES has that
    capability, but firewalls like Checkpoint does.
