I downloaded WireShark today and must say that after the initial run through I'm very impressed.

Obviously a Win/Unix port based on appearance, but it can do what I've had a hard time finding any other free Mac app. capable of doing.

It's keeps detailed logs of all network traffic and displays them in a handy GUI interface.

If anyone is interested in where their traffic is going you should give this app. a shot.

I only took off points because the appearance is obviously not Mac standard which some people won't like, and quitting the app. required a force quit.

Considering what it brings to the table they are minor complaints though.
