As Wireshark captures at Layer 2 of the OSI Reference Model, we can see everything from the frame, packet, segment/datagram and above.īy default, Wireshark color codes the different packets based on a set of color rules.
Wireshark will provide you with a ton of information about each packet going through the network.įor those just starting out in learning about networks, this is a great opportunity to learn about the OSI Reference Model as well. Once the capture button is pressed, Wireshark will begin capturing packets and displaying all the traffic going in and out of the previously selected interface in real time.
Once the program is launched, select the network interface to capture and click on the sharkfin at the top left of the application right under the menu bar to begin capturing packets. Once Wireshark is installed, launch the program to begin. Launch Wireshark and Begin Capturing Packets Once downloaded, launch the Wireshark installer which will guide you through the Wireshark installation process. As mentioned previously, Wireshark is available for Windows, Mac, and Linux. Simply choose the edition you’d like to download. Wireshark can be downloaded at the Wireshark website here. Wireshark Tutorial Download and Install Wireshark Wireshark is a very powerful tool and because it captures any data going in and out of a certain network interface, it may raise red flags with network administrators if you run the tool at places such as workplaces, schools, businesses, etc.
We also want to use this opportunity to educate our readers on why using encryption is so important, even when simply browsing the internet.Ĭaution: Before starting, ensure that you’ve been permitted to analyze the network you’re planning to run Wireshark on. Our tutorial today will guide you through some of the basics of using Wireshark to capture packets, filter them, and understand the data being presented. For network admins and network security professionals, one of the most important tools to learn to use is Wireshark (formerly Ethereal), a free and open source network analyzer/packet sniffer software for Windows, Mac and Linux that will allow network admins to quickly and easily capture frames, packets, segments/datagrams, and above in real time to monitor traffic going in and out of their networks.
