Easy program to sniff and view IP packets (TCP, UDP, ICMP).
PacketViewer allows you to view IP packet messages and IP packet informations in real time.
You can easily listen on Windows system ports (Eg. Ports 135, 445, 1026-1028).
An IP Converter tool allows you to convert IP Addresses to Host Names.
The button "Options..." opens the PacketViewer options:
Protocol Filter, TCP packets Filter, Ports Filter, Resolve IP Addresses (displays host names in real time, but adds some UDP packets),
TCP Test, UDP Test, Ping Test.
Requires Microsoft .NET Framework 2.0.
