About tcptrack

tcptrack is a sniffer which displays information about TCP connections it sees on a network interface. It passively watches for connections on the network interface, keeps track of their state and displays a list of connections in a manner similar to the unix 'top' command. It displays source and destination addresses and ports, connection state, idle time, and bandwidth usage. The following screenshot explains a lot:

News

Aug 3, 2011 - tcptrack 1.4.2 released

tcptrack 1.4.2 is now released. This fixes a heap overflow in the parsing of the command line. Thanks to Patroklos Argyroudis for the discovery and Chow Loong Jin for a fix.

As stated by Patroklos Argyroudis, this may have security repercussions if tcptrack is configured as a handler for other applications that can pass user-supplied command line input to tcptrack.

A number of other miscellaneous problems have been fixed as well.
