1. Introduction to TCPDUMP
TCPDUMP is a command-line packet capture tool that runs in a Unix and Linux environment. It can provide very detailed information about any network conversation that runs across the wire.
An advantage of TCPDUMP is that it can be run remotely through a SSH or TELNET session, and the machine running TCPDUMP does not have to be running x-windows. The application uses very little overhead, since it's a non-graphical interface.
