imsniff

Simple program to log Instant Messaging activity on the network

The imsniff program can be used to log IM activity on the network. It uses libpcap to capture packets and analyzes them, logging conversation, contact lists, etc. Users connecting after imsniff is started can get pretty good results, including complete contact lists and events (displaying a name change, for example). Users already connected will be able to get the conversations, but will miss the other information. The only required parameter is the interface name to listen to. This can be any interface that libpcap supports. A sample imsniff.conf.sample file is included. imsniff is beta software, for now, only MSN is supported. Others could follow.
