Traffic analysis command-line utility

Rate is a swiss-army-knife command-line traffic analysis tool, designed to help a network administrator to see what is happening at a router at the moment. Unlike tcpdump1, rate uses statistical and stream-oriented methods, and will never produce an output stream at a speed beyond human perception. The output is less accurate, however. Rate features four different operating modes, designed to perform the following tasks estimating overall traffic rates, determining nodes generating the highest traffic, determining connections and flows generating the highest traffic and extracting strings from packets.
