mdns-scan - Scan for mDNS/DNS-SD services published on the local network
mdns-scan is a tool for scanning for mDNS/DNS-SD published services on thelocal network. It issues a mDNS PTR query to the special RR_services._dns-sd._udp.local for retrieving a list of all currently registeredservices on the local link.
has no commandline options.
mdns-scan is not a good mDNS citizen since it queries continuously for servicesand doesn't implement features like Duplicate Suppression. It is intended forusage as a debugging tool only.mdns-scan is incomplete since it doesn't resolve mDNS services for you - itjust dumps their PTR RRs. To understand these records you need minimalknowledge of DNS-SD and how it works.mdns-scan does not terminate on its own behalf. It scans for servicescontinuously until the user kills it by pressing C-c.mdns-scan does not rely on a local mDNS responder daemon. It has nodependencies besides the GNU libc. It has been tested on Linux only.mdns-scan does NOT scan for local mDNS enabled hosts or A/AAAA RRs, it scansfor DNS-SD registered services, nothing else.
