tcpdump
Tcpdump, a powerful command line packet analyzer, allows users to view the contents of packets sent or received by a computer over a network. It runs on most Unix systems, including Linux and Solaris. It also works with FreeBSD NetBSD OpenBSD and MacOS. Tcpdump is able to read packets either from a network card or from an existing packet file. It also offers the option to write packets on standard output or to a file. Users can apply BPF filters to limit the amount of packets that are processed. This makes it easier to use on networks with high traffic. The tool is distributed with the BSD license and is therefore free software. Tcpdump can be installed as a native package on many operating systems, making it easier to install updates and maintain the system.
