It is a common mistake to believe that capture filters and display filters work the same way in Wireshark. This section will only scratch the surface of what is possible with Wireshark so for the time being please consult the Wireshark Wiki for further information about creating filters. Wireshark provides a powerful filter language which not only allows you to narrow down the packets you want to capture but also to sort, follow or even compare their content. Now when you now start capturing again only packets applicable to the tcp protocol filter are captured and displayed. Select the network interface of your choice and just type ‚tcp‘ into the capture filter dialog box on the bottom of the configuration window like below. This time we want to apply a filter before we start capturing data. You can select network devices, set capture filters and configure the capturing process. This menu provides options similar to those you already saw on the welcome screen. This will open the capture configuration menu. To do so open the capture configuration window by clicking on the cogwheel icon. To avoid slowdowns you should not capture unfiltered network traffic. Filtering TrafficĮven the smallest network will produce a lot of static data that can result in very large capture files. Stop the current capturing process by clicking on the red stop button. The window will change to the main capturing view and immediately display everything passing the network on your selected capturing device as see below. Once selected you can start recording packets by clicking the start icon in the top left of the user interface. To select multiple interfaces at once just hold down ctrl and select all interfaces you want to listen on. To finally start capturing data on your network you first have to select one or more of these network interfaces by simply clicking on them. A small traffic preview is shown next to the interface names so it is easy to distinguish between interfaces with or without direct network access. Once Wireshark is started you will be greeted by a welcome screen like the one shown above listing all available network connections. If your welcome screen is blank and does not show any network interfaces it usually means that your user account is lacking the necessary access rights. Running Wiresharkĭepending on your operating system and user settings you might have to run Wireshark with admin privileges to capture packets on your network. For more information about building Wireshark from source please take a look at the official developers guide.

Wireshark is open source and free which makes it one of the most popular network analyzer available. Being an analyzer, Wireshark can only be used to measure data but not manipulate or send it. It is used to capture data from a network and display its content. This article will be covering Wireshark including the following topics: This lesson assumes basic knowledge of networking concepts.
