Tcpdump 4.2.0

Powerful command-line packet analyzer
  1 Screenshot
Tcpdump is an open source tool for protocol debugging, network monitoring and data acquisition.

Tcpdump prints out a description of the contents of packets on a network interface that match the boolean expression.

Tcpdump can also be run with the -w flag, which causes it to save the packet data to a file for later analysis, and/or with the -r flag, which causes it to read from a saved packet file rather than to read packets from a network interface.

In all cases, only packets that match expression will be processed by tcpdump.
