Now that we got a very short overview of Wireshark, let us start with the Wireshark HTTP lab. The Packet-display filter filed, in this filed you can place information to filted the packages showed in the Packet-listing window. The Packet-content window, display the content of the captured frame in both ASCII and hexadecima format.ĥ. The Packet-header details window, provide details about the packed selected in the “Packet-listing windows”.Ĥ. The Packet-Listing window, shows a one-line summary for each packet captured.ģ. The command menus, located at the top of the windows it containd buttons and/or pulldown menu for actions such as, save, capture, exit, etc.Ģ. The Wireshark window is divided in five major compnonets (See figure below):ġ.
To work with Wireshark it is important that you understand how it shows the captured information.
To stop capturing data, just click on the stop icon (red square). Then select Capture in the top menu and click on Start, or click on the Shark’s Fin icon at the top-left of the window. Ethernet card, wireless card, etc. (in my case I am using a wireless connection therefore I’ll select the “Wireless Network Controller”). To start capturing packages you should first select the interface you will be working with e.g. You might be seeing a windows “similar” to the one showed in the figure below. So to start with this lab let’s open Wireshark. If you are new to Wireshark I’ll recommend to review the Introduction to these labs, which explain some basic concepts and the initial steps to use WireShark. In this blog I will focus mainly in solving each Lab and won’t be explaining basic concepts with much details. Most commonly used for network troubleshooting, analysis, software and communications protocol development. So what is Wireshark? In simple words Wireshark is a packet analyzer. This blog series I will be solving a number of Labs to understand a bit more how different internet packages send or receive information, and how can we use Wireshark to analyze these packages.
