I've spent about an hour in a metro with PineAP in active mode, and internet input. It was about 5-13 different clients connected at any moment. some of them for 20 minutes. I've collected huge list of SSIDs and MACs. 40 minutes of watching on the HTTPeek. "sniffer enabled. listening active". And there is nothing in HTTPeek. No URLs, no images, no cookies. What is my mistake?
