Niklaus, This looks cool! Here are some comments: 1. Please convert the script to use structured output [1]. This is usually a matter of changing some tables to stdnse.output_table() and then changing lines like this: search_response[1] = "IP address: "..knx_hpai_ip_address into this: search_response["IP address"] = knx_hpai_ip_address 2. Seems like we have unnecessary information in the output. I think the Status part should be obvious from the number of gateways listed in the output. So the output could be more like: | knx-gateway-discover: | 192.168.178.11: | Port: 3671 | KNX address: 15.15.255 | Device MAC address: 00052650065C | Device friendly name: IP-Viewer | Supported Services: | KNXnet/IP Core | KNXnet/IP Device Management | KNXnet/IP Tunnelling |_ KNXnet/IP Object Server 3. Could you also add target discovery? Use target.lua [2] 4. Try to grab the lport from the socket:get_info() call and use that instead of the hardcoded 55772, unless that's needed for the protocol to work. That way we know that the local port is available and not in use by some other service. Thanks again for putting the effort into this!

Howdy, KNX is "...the worldwide STANDARD for all applications in home and building control, ranging from lighting and shutter control to various security systems, ...building control with a single, manufacturer independent design and commissioning tool (ETS), with a complete set of supported communication media (TP, PL, RF and IP) as well as a complete set of supported configuration modes..."[1]. This script discovers KNX gateways which are be used to communicate and configure bus devices over IP driven networks. It sends a multicast IP packet where all gateways should respond with various information about themselves. It is based on the llmnr-response.nse script as it technically does the same thing. This script is also available on GitHub [2].
