“horst” is a small, lightweight IEEE802.11 wireless LAN analyzer with a text interface. Its basic function is similar to [URL="http://www.tcpdump.org/"]tcpdump[/URL], [URL="http://www.wireshark.org/"]Wireshark[/URL] or [URL="http://www.kismetwireless.net/"]Kismet[/URL], but it’s much smaller and shows different, aggregated information which is not easily available from other tools. It is mainly targeted at debugging wireless LANs with a focus on ad-hoc (IBSS) mode in larger mesh networks. It can be useful to get a quick overview of what’s going on on all wireless LAN channels and to identify problems.[LIST][*]Shows signal/noise values per station[*]Calculates channel utilization (“usage”) by adding up the amount of time the packets actually occupy the medium[*]“Spectrum Analyzer” shows signal levels and usage per channel[*]Graphical packet history, with signal/noise, packet type and physical rate[*]Shows all stations per ESSID and the live TSF per node as it is counting[*]Detects IBSS “splits” (same ESSID but different BSSID – this is a common driver problem)[*]Statistics of packets/bytes per physical rate and per packet type[*]Has some support for mesh protocols (OLSR and batman)[*]Can filter specific packet types source addresses or BSSIDs[*]Client/server support for monitoring on remote nodes[/LIST]“horst” is a Linux program and can be used on any wireless LAN monitor interface. The latest git version can also be compiled and used on Mac OSX.
