A new major Kismet version has been released, almost 3 years after the previous stable release. The new 2019-04-R1 version features a massively rewritten code base, a new web UI, support for non-WiFi capture types, and much more. Kismet is a wireless network detector, package sniffer, and intrusion detection system. It works with any wireless card that supports raw monitoring (rfmon) mode, and can sniff 802.11a/b/g/n traffic.
