Network Analysis: Packet Capture
In this lab, you’ll practice packet collection and analysis. When you’re finished, you’ll have collected and processed packet information generated from visiting a website..
Terms and conditions apply.
Getting Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!
Collect Packet Data with tcpdump
In this challenge, you will be visiting your company website and collecting incoming and outgoing packets from the website.
Capture Packet Data with Wireshark
Viewing data on tcpreplay may be hard to visualize. In this challenge, you will be using wireshark to collect, visualize, and analyze the packets in a pcap file. You will see that a lot of different types of traffic flows to and from the network and how requests may consist of many packets.
Use tcpdump and tcpreplay to Replay Server Responses
In this challenge, you will be using tcpreplay to only replay traffic coming from the server on your workspace machine and ignore all client requests..
The Last Challenge
Welcome to the final challenge! This is your last chance to experiment in the environment. Clicking Finish Lab will end this little world that flittered into existence just for you.
Provided environment for hands-on practice
We will provide the credentials and environment necessary for you to practice right within your browser.
Follow along with the author’s guided walkthrough and build something new in your provided environment!
