All information that travels across a network is sent in packets. For example, when an email is sent from one computer to another, it is first broken up into smaller segments. Each segment has the destination address attached, the source address, and other information such as the number of packets and reassembly order. Once they arrive at the destination, the packet’s headers and footers are stripped away, and the packets are reconstituted.
A packet sniffer is a device or program that allows the user to eavesdrop on traffic traveling between networked computers. The program will capture data that is addressed to other machines, saving it for later analysis.
Purpose
This project introduces the Wireshark packet sniffer. During the project you will capture packets, use a capture filter, and look at the contents of a packet.
