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.

Thu Dec 06 2012 - Busy busy busy. Two new Android utilies now up - rfmon with a USB NIC, capturing to pcap, no root required, in Android PCAP Capture. To go with that, an easy way to upload pcap files from Android to CloudShark, a web-based implementation of Wireshark: CloudShark Uploader
Mon Jul 23 2012 - While phy-neutral is finishing up, added Ubuntu 12 packages for Kismet 2011-03
Thu Jul 05 2012 - Kismet moving to Git source control. Subversion is moved to code-old/svn (details on the download page) and the old SVN repository is disabled. Git checkouts at https://www.kismetwireless.net/kismet.git
