@bushman: I can’t remember exactly how I got the answer I wanted out of WireShark, it was a few weeks ago and I’ve lost the details already. I seem to remember there being a way to filter the list of captured packets by protocol type, which gave me exactly what I was looking for.
I wish I had some secret answer to how I manage my time. The answer is very simply that I spend way, way too much of my nights and weekends (and even vacations, which is where I am right now) doing this stuff!
