This is the continuation of my CompTIA Network+ Lab walkthroughs. The purpose of this is to give some practical examples of how you can learn AND implement the tools and topics covered in the Network+ certification. Today way are using a packet sniffer called Wireshark to look at and analyze TCP and UDP traffic (specifically Telnet and DNS traffic). This lab is also applicable to information that you would need to learn for the Security+ and CCNA certifications, and is essentially a Wireshark tutorial for beginners. This lab is inspired by the TCP and UDP labs (Labs 6 & 7) in the 101 Labs Comptia Network+ book by Paul Browning. It is a great resource for studying the Network+, you can find it here:

This lab will require the use of Wireshark, you can download it for free here. Here is the Wireshark cheat sheet that I covered in this lesson. So far I have done 10+ Network+ Practical Lab videos, if you’d like to see the rest you can find them here.
