About this tool

Tcpdump is a data-network packet analyzer computer program that runs under a command-line interface. It allows the user to display TCP/IP and other packets being transmitted or received over a network to which the computer is attached.

Pro Tip: Focus on understanding the core options first. You can use the generated command directly in your terminal, and view the Command Breakdown above to see what each flag does.
