ttt is yet another descendant of tcpdump but it is capable of real-time, graphical, and remote traffic-monitoring. ttt won't replace tcpdump, rather, it helps you find out what to look into with tcpdump. ttt monitors the network and automatically picks up the main contributors of the traffic within the time window. The graphs are updated every second by default. Features: Automatic Ranking of Protocols and Hosts Real-Time Monitoring Remote Monitoring with IP-Multicast support Accepts tcpdump output IPv6 Aware (experimental) Portable and easy to customize The TTT homepage is at: http://www.csl.sony.co.jp/~kjc/software.html (libBLT is provided here for your convenience; ttt also requires libpcap)
