Can Wireshark capture TLS traffic?
I have a wireless network on my machine, and would like to capture the traffic from another machine to that wireless network.
In my understanding, that machine will need to be running Wireshark. How do I set this up, so that the wireless NIC captures the traffic? Thanks!
There are a few things you can try: If you are using Windows then you might be able to use TCPview or something similar (I'm not sure how to configure that but I'm sure you could do it if you were really bothered). You can install Wireshark on a machine that has wireless access (or you can set up an Access Point on your laptop with wireless) then monitor the wireless network that you want to capture and see if Wireshark shows any captured packets. If you have access to a Linux box that you can configure and deploy Wireshark on then you could deploy Wireshark on that system to monitor the network.
