Please post any new questions and answers at ask.wireshark.org.In particular, read about the OSI Model if you want to know what the purpose of the different layers you might see when you take a look at packets using a capturing tool.For most people this probably means starting by interpreting the Ethernet frame.
This tells you which device the packet is destined for, or if its a broadcast or multicast address (intended for multiple devices). The Ethertype field indicates which kind of protocol the device reading the packet should use to interpret the rest of the packet. The various kinds of protocols which might operate over Ethernet are defined by IANA. Read Wireshark Packets For Free From TheYou can download it for free from the company website; you should choose the latest version for your platform from the stable release section. Read Wireshark Packets Software From StartIm going to cover this software from start to finish, all the way from downloading the application to accessing advanced features. Youll learn the ins and outs of analyzing packets, using filters, and turning the information you get into usable data. Throughout the tutorial, Ill work in some frequently asked questions and shortcuts to make navigating this software a breeze. ![]() Once these packets are broken down, you can use them for real-time or offline analysis. This is great for users who want to generate statistics based on this data or change it into a handy graph. The interface is user-friendly and easy to use once you know the basics of capturing packets.
