It could be useful to watch for a RST. It would allow for testing to a server that is not thrilled with talking to a test tool.

We have a case where a service is not designed to talk with many clients. Instead it only talks to one client on one fixed port. If the same client trys to establish a 2nd session it is refused. RST

This keeps us from being able to run PingPlot on the client to the server on the same port that we use for the production session. Two firewalls prevent use of other ports. We have asked for ICMP access for testing but the provider is reluctant.

Other wise would would say that I love Ping Plotter and was pleased to see it got a nod from NetworkWord (Mark Gibbs)
