Wireshark has the ability to capture a ******* zillion different types of traffic. So there is a zillion different filter options that allow it to focus on specific conditions.

Wireshark is not for the timid or the weak. The Official Study guide by Laura is pretty much the bible of packet capturing and the new book on campus for the new Wireshark Certification. If you're going to use it, you had better freshen up on your transport and networking layer traffic/protocol types.

Wireshark is a GUI based protocol analyzer which I really love, but sadly it has so many vulnerabilities all the time.....

So the protocol analyzer of choice is TCPdump, or Windump for me

No, you do not have to pay for wireshark. It's freely available from the website. It runs on Windows, Mac, Linux.
