Since 3.1, kismet changed the configuration format, especially for the sources naming. See the list of sources in kis_packsources.cc . The naming of the rpm is not the same as the upstream authors. They change so oftern i decided to carry a custom format for rpm version. Format of the version is 3.1.YYMMNN with : YY = Year MM = Month NN = Number of version this month ( so feb 2004, first version is 040201 ) This version is labeled kismet-2004-10-R1 on the website.
