![]() ![]() ![]() When you start typing, Wireshark will help you autocomplete your filter. For example, type dns and you’ll see only DNS packets. The most basic way to apply a filter is by typing it into the filter box at the top of the window and clicking Apply (or pressing Enter). Wireshark needs to use the npcap packet capture library for loopback traffic to be detected. ![]() Double click on 'Adapter for Loopback Traffic Capture'. There is a dashboard when the application opens with a list of network interfaces. If it does, it means the traffic does not go through the proxy and you need to adjust the configuration and the sending of requests in your code. That’s where Wireshark’s filters come in. As of March 18, 2022, Wireshark can capture traffic on the Loopback interface. So you can check if your application works at this time. What you should do is to run RawCap, which is a sniffer that can capture traffic to/from the loopback interface in Windows. So the driver service wasnt running but apparently some vestige of it remained. In this case, you will not have internet access. Device manager also detected the Npcap loopback interface. In order to determine if your requests respect the Fiddler Classic's proxy, you can try stopping the Fiddler Classic application and manually set your OS proxy settings to point to the Fiddler address: http=127.0.0.1:8888 https=127.0.0.1:8888 (which would not be available at that time). As far as I get it, both SMSniff and Wireshark work on the network adapter itself, no matter what is the proxy configuration and who respects it. Fiddler Classic works as a proxy tool, so it is required for the requests' sender to respect the proxy configuration in order to see them in the tool. I do not have experience with SMSniff, but from what I've read, I think both SMSniff and Wireshark work on a different level of capturing the traffic. Thank you for the additional information. ![]()
