12/31/2023 0 Comments Wireshark promiscuous mode windowsI’m not sure if that’s normal, but as far as I found out Wireshark can’t modify that setting because it doesn’t have the sufficient privileges to do that. Unfortunately, even with npcap installed correctly it doesn’t seem to work if you click it (at least in my case), because the check mark disappears again after a short moment. You can open that dialog from the main menu via “Capture” -> “Options” or by pressing CTRL-K. If you run Wireshark, you’ll notice that you have a “Monitor Mode” checkbox in the capture interface dialog for your WiFi cards. Important: you need to make sure “Support raw 802.11 traffic (and monitor mode) for wireless adapters” is checked: If you recently installed Wireshark 3.x (or later) you should automatically have replaced WinPCAP with npcap, unless you didn’t allow the installer to do that. If you want to know more about the differences between the two, check this comparison. Instead, the npcap libraries are used, which replace the discontinued WinPCAP libraries. Since Wireshark 3.0 came out WinPCAP is no longer the default capture library installed. I use either Alfa cards or, in this case, a NetGear A6210, which I bought at a local electronics store. There’s a matrix available that you can use to check if your card is supported. Unfortunately, not all WiFi cards support monitor mode on Windows. Requirement 1 – a WiFi card with monitor mode The npcap capture libraries (instead of WinPCAP).A WiFi card that supports monitor mode.To get the radio layer information, you need at least three things (other than Wireshark, of course): There’s nothing related to the radio layer, so troubleshooting the wireless connectivity is not possible this way. This concerns me because the whole point of this is to be able to analyze all data going in and out of a program.Figure 1 – “Wireless” capture without monitor modeĪs you can see, the capture looks just like a normal Ethernet capture would. I’m new to voip, docker, wireshark, and networking in general, so figuring this all out has been hard.Īnother concern I had was that I couldn’t find anything when filtering for the specific website that I pinged within the packets in wireshark, just the ip addresses. Based on some research, the best way to do that would be to isolate that program in a docker container and track all of the traffic going in and out of that docker container through wireshark. Here is my end goal, to provide some context: I would like to run a voip program and track all the data that’s going in and out of it to have a better understanding of how that works and how to protect my privacy. Why can’t I see the ip address of the docker container on wireshark? Shouldn’t it have its own interface? In fact when I check the ip addresses associated with each interface on wireshark, I don’t see it there either. I never see the ubuntu IP show up anywhere during these tests.
