![]() First, you’ll need to mirror the traffic into a LAN port. If, however, I run the application on PC B or C as well as WireShark, then that computer can see the traffic between the application and the CAN-Ethernet bridge. You can only capture router packets with Wireshark if you have a router that supports port mirroring. I don't seem to be able to capture any packets going between PC A and the CAN-Ethernet bridge (although they are communicating with each other) with WireShark on computers B or C. If I ping the CAN-Ethernet bridge, I can see the pings in Wireshark but only on the laptop doing the pinging. When another computer it talking to your computer wireshark can see that traffic. When you are talking to a remote computer, wireshark can see the responses (from both nodes). ![]() But why can't I see any TCP packets going between PC A and the CAN-Ethernet bridge? The Wireshark will capture packets your computer can see on it’s network interface. I can ping the CAN-Ethernet bridge form PCs B and C. PC A sends and receives TCP packets (mostly) successfully to the CAN-Ethernet bridge.įor some reason I don't understand I can't run npcap on computer A so I have also connected two other computers B and C to the same Ethernet switch both running Wireshark. When using this, remember to specify the. (Optional) Type in a filter in the 'using this filter' field to narrow the scope of capture, such as: host ipaddressorname, e.g. Begin capturing configuration by selecting the capture icon (green fin). Also connected to the switch is a CAN-bus-to-Ethernet bridge. Launch Wireshark from the Start Menu shortcut. so, I 'guess' you are trying to capture wifi/wlan traffic of other machines. In this article, we will look at the simple tools in Wireshark that provide us with basic network statistics i.e who talks to whom over the network, what are the chatty devices, what packet sizes run over the network, and so on. I have a Windows 11 PC A connected to an Ethernet switch. capturing packets of other devices on a wlan/wifi interface One Answer: 0 I heard we should do some changes in the wi-fi settings.
