Chapter 4 - Project 4-2

Wireshark is a free and open-source packet analyzer. It is utilized for network troubleshooting, analysis, software and publications protocol development, and training. Originally named Ethereal, the project was renamed Wireshark in May 2006 due to trademark issues.

The computer you used for this project?

I installed Wireshark on my Apple Macbook Air as I felt installing it on my HP Desktop would’ve taken too long since it is an older HP model; therefore, I used my newer and faster laptop.
