![]() install Wireshark and follow the on-screen instructions.The source code as well as binary installers for Windows and Mac OS X are available at. This section describes how to use Wireshark for OPC UA protocol analyzing.įirst you need to install Wireshark. But still we got something new right ☺.Using Wireshark to Analyze OPC UA Binary Protocol This process may not work if the connection is HTTPS or any other frame is missing. This is one working method to extract live video file from Wireshark. One observation is, we can see “ tcp.stream eq 2” filter got applied on Wireshark main window when “follow TCP stream” was clicked. Now go the live.mpeg and play it with KMPlayer or supported player. Note: You need to wait to let Wireshark process all packets into Raw data.ĭ. Note: We can do follow TCP stream on HTTP frame or TCP frame. Here is the screenshot for graphical understanding. So frame 18 is the frame we are looking for. Then we can see same ports are being used for further TCP frames in capture. Now if we select packet number 18 (HTTP GET) we can see TCP src port as 44940 and dest port as 8080. We should see many TCP data packets after HTTP GET. So this is not the HTTP packet we are looking for. Packet number 7 is HTTP get and packet number 11 is the HTTP reply. After putting “ http” filter in Wireshark we can see only 3 packets like below. We need to find out appropriate TCP stream or HTTP frame.
