How to test a TCP-connection

Sometimes it’s not enough to estimate the packet loss ratio only, but to make sure that a TCP-connections are stable. Run the “server” instance (sockping -m server -p 65513) on some host and run the “client” (sockping -m client -h 13.13.13.13 -p 65513) on another one, and the “client” will connect to the “server” and then it’ll be sending probe messages and expecting replies. If the TCP-session is broken, the “server” states it to STDERR.
