Maybe a fun idea - run an application on both sides of a remote TCP connection that records but doesn't respond to TCP RST packets. Then see how many times you get "reset".

You can just drop RST packets.

    iptables -I INPUT -p tcp --tcp-flags ALL RST,ACK -j DROP
    iptables -I INPUT -p tcp --tcp-flags ALL RST -j DROP

That looks like exactly what I did, but it was a pain trying to get random users to do run code as root.
