killabit

Description:

killabit.exe is a windows console utility that sniffs network traffic and shows you a brief report on bytes sent, organized by MAC address pairs (at layer 2), IP address pairs (layer 3) or IP:Port pairs (layer 4). It is intended as a quick and dirty "what is my traffic doing" rather than a fully featured network sniffer. In particular - it doesn't log or analyze the packets beyond what is necessary to increment the counter for the address pair that it is watching.

This was a quick and dirty write, and it shows if you look at the code.

Requirements:

Killabit uses the Pcap.Net .NET wrapper for WinPcap. Here is a link to the Pcap.Net license.
