Note: It’s much easier to compare the captured packets if you bring them up in separate windows.Īs mentioned, Wireshark uses a color-coding system for data visualization.
You can also further expand the tree to access the details of each protocol contained within the packet.įor a more comprehensive overview, you can display each captured packet in a separate window. If you want to access the information regarding a single packet, all you have to do is locate it on the list and click. Once the packets are captured, Wireshark organizes them in a detailed packet list pane that’s incredibly easy to read. Once you master these fundamental steps, you’ll be able to inspect the traffic flow of your network and troubleshoot problems with more efficiency. Below, you’ll find step-by-step instructions and breakdowns of the basic network analysis functions. He has worked with Wireshark for over 15 years.In this tutorial, we’ll explain how to capture, read, and filter packets using Wireshark. Technologies that Rick Bodnar is proficient in include TCP/IP networking, IP routing, VPN Tunneling, DNS, to name a few. In addition, he has also been an adjunct instructor for higher education institutions such as Kent State University, Penn State University, and the University of Mount Union. In that time, he has held a variety of IT management positions. Rick Bodnar is an IT professional with an extensive technology background he has worked with technology for over 24 years. Lastly, you'll learn to expand upon the capabilities and functions of Wireshark plugins and APIs and build on your Python skills by using PyShark to modify how Wireshark captures and filters packets.īy the end of this course, you'll have learned to customize Wireshark in-depth for network security analysis using commonly used protocols and to configure it effectively for troubleshooting and daily monitoring purposes. You will delve into analyzing applications aimed primarily at web browsing master commands that can also be set up and configured to run from the command prompt and learn to use the new feature in Cisco routers and switches to capture packets directly from devices and mirror (SPAN) ports.
The course focuses on packet analysis for security tasks, command-line utilities, and tools that manage trace files. Learn to master Wireshark's features, analyze different layers of your network protocol, and search for abnormality in your network traffic.
As you progress through the course, you will discover different and important ways to create, use, capture, and display filters. Mastering Wireshark 3 (2nd Edition) will help you gain expertise in securing your network.
