Linux Sniffing

This lesson focuses on Linux sniffing. Sniffing is a passive activity that involves opening ports and listening for data and can be a useful tool in identifying what kind of traffic is on a network. It can also tell you what kind of machine and how many machines are on a network. This lesson focuses on the following command line tools:

Tcpdump: designed to receive pockets in a raw socket and print relevant bits on the screen.

Tshark: used to capture packets into a file.
