Kismet is an 802.11 layer2 wireless network detector, sniffer, and
intrusion detection system. Kismet will work with any wireless card which
supports raw monitoring (rfmon) mode, and (with appropriate hardware) can sniff
802.11b, 802.11a, 802.11g, and 802.11n traffic. Kismet also supports plugins which
allow sniffing other media such as DECT.
Kismet identifies networks by passively collecting packets and
detecting standard named networks, detecting (and given time, decloaking) hidden
networks, and infering the presence of nonbeaconing networks via data traffic.

Mon Apr 08 2013 - Kismet-2013-03-R1b released. Somehow the latest configure script didn't get into the R1 release so it blew up on libnl1 detection; No code changes, no package changes.
Wed Mar 27 2013 - Kismet-2013-03-R1 released! While this does not have major new features (phy-neutral is still in development) it includes a long list of bugfixes, including better ncurses color support, radiotap fixes, better interface control when setting channels, memory leak fixes, better packaging for distros, and various other quirks.
