They are set before starting to capture traffic.Here’s an overview of each filter’s features and uses: Capture filters are a bit less intuitive since they are cryptic. Once you create a few display filters, it becomes easy to write them. You can display packets based on several factors:ĭisplay filters use a boolean operator syntax and fields that describe the packets you’re filtering.

With display filters, you can focus on packets you’re interested in and hide those not currently important. The former is used for filtering while capturing packets. Wireshark supports two filtering languages: capture filters and display filters. You can apply destination filters to restrict the packet view to those with a specific destination IP showing in the filter. There’s a table showing common keyboard shortcut commands here. You can control the packet lists and navigate through details entirely with your keyboard. Statusbar – captured data and ongoing program state information.Bytes pane – data from the packet list pane packet, highlighting the chosen field in that pane.Details pane – more information about the selected packet from the packet lane.Packet list pane – captured packet summaries.Filter toolbar – you can set display filters here.Main toolbar – quick access to items you often use from the menu.The main window in the Wireshark interface consists of several parts:

You can click on Capture, then Interfaces from the menu, and choose the appropriate option. One of the first things you have to do is choose a network interface out of the list of networks on your computer adapters. Just download the executable and click on the file to install it.Īfter downloading and installing Wireshark, you can access it from your local shell or window manager. In case you still haven’t, you can do so here.

Learning about network protocol internals.

Here’s why people may want to use Wireshark: This brought Wireshark lots of community support, removing the cost as a barrier and making room for a wide range of training opportunities.

The software is open-source and supports all major platforms. That all changed with the advent of this app. Wireshark also ingests and analyzes traffic from various other protocol analyzers, making it straightforward to review past traffic at specific points.īefore Wireshark, network tracking tools used to be very expensive or proprietary. This makes it equally convenient for first-timers as well as for network monitoring professionals. Wireshark comes with the top-notch ability to filter packets during capture and upon analysis with different complexity levels.
