Packet Peeper is a free network protocol analyzer (or ‘packet sniffer’) for Mac OS X. Its features include: TCP stream reassembly. Privilege separation. Simultaneous capture sessions. Filters, which may be defined at any time. Packet Peeper uses the same syntax as tcpdump and Wireshark (or any other program that uses the pcap library). Capsa Free is a network analyzer freeware for Ethernet monitoring, troubleshooting and analysis. It provides users with great experience to learn how to monitor network activities, pinpoint network problems, enhance network security. Capsa Free is a special edition of Capsa Network Analyzer for students, teachers and computer geeks to learn. Wireshark A well-known free packet capture and data analysis tool.

Kismet is a wireless network and device detector, sniffer, wardriving tool, and WIDS (wireless intrusion detection) framework.

Kismet works with Wi-Fi interfaces, Bluetooth interfaces, some SDR (software defined radio) hardware like the RTLSDR, and other specialized capture hardware.

Kismet works on Linux, OSX, and, to a degree, Windows 10 under the WSL framework. On Linux it works with most Wi-Fi cards, Bluetooth interfaces, and other hardware devices. On OSX it works with the built-in Wi-Fi interfaces, and on Windows 10 it will work with remote captures.

Kismet plugins

With the new Kismet codebase (Kismet-2018-Beta1 and newer), Kismet supports plugins which extend the WebUI functionality via Javascript and browser-side enhancements, as well as the more traditional Kismet plugin architecture of C++ plugins which can extend the server functionality at a low level. Kismet also supports external ‘helper tools’ which can extend server functionality via scripting tools such as Python.

Kestrel

Kestrel adds live mapping to the Kismet UI using the Leaflet library, and overlays network and device locations on a live map with pin grouping for dense areas.

You can find Kestrel at https://gitlab.com/SoliForte777/Kestrel and see a video of it in action
