CommView

CommView is a tool for monitoring the status of your network connection. It is very useful for network administrators and programmers, and includes the ability to analyze information packets and control data flow.

The program displays a list of established network connections, IP statistics, and individual examined packets.

CommView unencrypts the different packets up to the last level by analyzing the main IP protocols: TCP, UDP, and ICMP.

You can save logs of the packets captured by CommView to later analyze them in case the need arises. Also, you can set up filters so that the program automatically eliminates all the packets that you don't want to capture.
