According to Peter Giannoulis of www.theacademypro.com, one particular open source tool hasn't received the attention that it deserves. Network Miner, a free, Windows-based passive network sniffer, allows users to gather network information that is host-centric rather than packet-centric.
In this short demo, Peter Giannoulis explains how Network Miner can be used to gather information from hosts on your network, including identification of ports, protocols, operating systems and other services.
