Wireshark will create huge files in a short amount of time and with lots of lines to investigate. So, unless explicitly asked, please, always run Wireshark on the device where the Nx Witness Media Server is running on. In this way the communication between the Nx Desktop Client and the Nx Media Server will be captured, while in most cases we like to investigate the communication between the Nx Witness Media Server and the camera or other video resources. Important: Often we get the files created on the Nx Witness Desktop Client computer, instead of one from the Nx Witness Media Server. Now you click F ile and select Save A s… and you give a proper name to the capture and you keep the extension as Wireshark/…-pcapng.When you finished the capture, stop the capture with the red square on the top-left of the screen.Double-click the interface or press the Start button on the top left (the blue shark fin).Single-click the Network Interface and enter the Capture Filter in the applicable field by entering.To perform the filtered capture, please follow the steps below: To collect the packets more efficiently, you can use the capture filter to grab only the specific communication you need, usually the communication between the Nx Witness Media Server Application and the camera or vice versa. If you have the choice between a wireless interface and a wired interface, it is preferred to use the wired interface since it provides a better quality capture with less clutter. The correct interface is the interface that connects the server to the camera. You can start the capture by either double-clicking the correct network interface or single-clicking on the correct network interface and clicking on the blue shark fin on the top-left of the screen.

It is a cross-platform application and available for Windows, macOS, and Linux.

Wireshark is a free and open-source packet analyzer application that is commonly used for network troubleshooting and analysis.

What is Wireshark, and how can I capture data? In this article we will explain how to create such a capture and what to keep in mind when capturing the data.Īlthough it is possible to capture the communication indirectly, this article will provide instructions for situations where Wireshark is installed and running on the same device that the Nx Server application is running on. Sometimes our support team will ask you to create a Wireshark capture, so they can analyze the communication between Nx Server and a camera.
