CS 3000: Wireshark Lab 1

Answers to be uploaded to Canvas on or before Wednesday, September 9, 2026. (Words typed, not handwritten.)

This is an individual or one-partner assignment. All work must be your own. You should not look at any other partnership's work (in whole or in part, on paper or on screen), nor allow anyone else to look at yours, during the course of this assignment. Nor may you submit the work of software programs as your own.

For this assignment, you may work with a partner. Make certain both names -- full names! -- are at the top of the homework answers file that at least one of you submits. If you choose to work with a partner, make certain both of you practice "driving" Wireshark through tasks.

  1. All the machines in the CS Lab (P-288) have Wireshark installed.
    However, the instructions here are specific to the Linux machines on the two rows closest to the door. The account you received an email about is valid on those machines.

  2. Capture files you might want to download to your computer's Desktop.

  3. To open Wireshark, use the Application Finder on a Linux computer. (The icon for the Application Finder looks like a magnifying glass, and should be at the bottom of your screen.) In the Finder window, type "Wire" in the box -- Wireshark should then be visible to you.

  4. To open a .pcap file, use the File menu and select Open. You should store .pcap files somewhere easy to find -- your Desktop would be suitable.

  5. You will complete this Wireshark packet sniffer lab.
