IP Spy

IP Port Spy will listen on a TCP or UDP port, and print the frames received in the main window. No frames are sent back in response to the frames received, although TCP connects are sent when a connect request is sent on a TCP port.

This software was developed with the IP developer in mind, as a means to test and debug network applications, or just to provide information about particular frames. The frames shown below in the main window are SNMP frames, with IP Port Spy listening on UDP port 161.
