You can simply filter on malformed to see all packets conaining malformed data:Įxample: Show only malformed packets: malformed Capture FilterĪ capture filter for the malformed pseudo protocol wouldn't make sense, as the malformed status isn't detected while capturing. Packet Capture: Wireshark listens to a network connection in real time and then grabs entire streams of traffic quite possibly tens of thousands of packets at. If there is a different method to identify or quantify these communications which will be easier than whireshark I would be glad to hear about it. If you type anything in the display filter, Wireshark offers a list of suggestions based. Location of the display filter in Wireshark.
