The main menu you can see in the image below contains the following options: The arrows below point to 4 arrows in the Packet Details section by pressing them, you can see the packet description. You can see an example in the following screenshot. If you select a packet from the upper section (Packet list), the middle section (Packet details) will display a description of the selected packet, and the lower section (Packet bytes) shows a canonical hex dump of the selected packet. The arrows in the screenshot below show the packet list (Upper section), the packet details (Middle section) and the packet bytes section (Lower section). The Wireshark user interface can be divided into 6 sections: Menu, Toolbar, Filter Toolbar, Packet List, Packet Details and Packet Bytes. Once you select your network device, double click it or press the fin icon located in the left upper corner below File.Īfter pressing the network device or the fin icon, Wireshark will start listening to the traffic. In my case, I will choose my wireless network interface, wlp3s0. You also can select Any to listen through all network devices.
In the Wireshark initial screen, you need to select the network interface whose traffic you want to analyze. Unprivileged users with access also can run Wireshark from the command line. If unprivileged user access was allowed, then you also can open Wireshark from the graphical environment under the Internet. If you selected Yes, then you can open Wireshark from the graphical environment as shown in the next screenshot. If you selected the option No, then you need to execute Wireshark with privileges as shown below.
If you are the only one using your computer, you can press Yes otherwise, it is recommended to press No. During the installation process, you will be asked if Wireshark can be executed as an unprivileged user or only as a root.
