From eSource Computers:
The eSource Network Packet Monitor is a protocol sniffer that was designed to help identify traffic that is traveling on a network. Once the 'sniffer' is started, the packets are listed in the window. Double click any packet and you will be presented with a detailed screen showing every aspect of the packet information. The registered version allows for real time logging of all traffic. This program also includes a comprehensive search tool that enables you to search the database for known port assignments by name, port number, or keyword description.
