Description:

Tcpdstat a program to extract statistical information from tcpdump
trace files. Tcpdstat reads a tcpdump file using the pcap library and
prints the statistics of a trace. The output includes the number of
packets, the average rate and its standard deviation, the number of
unique source and destination address pairs, and the breakdown of
protocols. Tcpdstat is intended to provide a rough idea of the trace
content. The output can be easily converted to a HTTP format. It also
provides helpful information to find anomaly in a trace.
