This will start Wireshark capturing on interface eth0. If you already know the name of the capture interface you can start Wireshark from the command line:.You can immediately start a capture using your current settings by selecting Capture → Start or by cliking the first toolbar button.You can start a capture from this dialog box using the Start button. See Figure 4.1, “The “Capture Interfaces” dialog box on Microsoft Windows” or Figure 4.2, “The “Capture Interfaces” dialog box on Unix/Linux” for more information. You can get an overview of the available interfaces using the “Capture Interfaces” dialog box (Capture → Options…).You can double-click on an interface in the main window.The following methods can be used to start capturing packets with Wireshark: If you have any problems setting up your capture environment you should have a look at the guide mentioned above. You need to capture at the right place in the network to see the traffic you want to see.You need to choose the right network interface to capture packet data from.You may need special privileges to start a live capture.
A comprehensive guide “How To setup a Capture” is available at. Setting up Wireshark to capture packets for the first time can be tricky. Stop capturing (or perform some other action) depending on the captured data.
The capture engine still lacks the following features: Simultaneously capture from multiple network interfaces.See Section 4.11, “Capture files and file modes”. Save packets in multiple files while doing a long term capture, optionally rotating through a fixed number of files (a “ringbuffer”).See Section 4.13, “Filtering while capturing”. Filter packets, reducing the amount of data to be captured.Simultaneously show decoded packets while Wireshark is capturing.Stop the capture on different triggers such as the amount of captured data, elapsed time, or the number of packets.Capture from different kinds of network hardware such as Ethernet or 802.11.The Wireshark capture engine provides the following features: 9. The “Remote Capture Interfaces” dialog boxĬapturing live network data is one of the major features of Wireshark.6. The “Edit Interface Settings” dialog box.
