MDNS-SCAN(1)                General Commands Manual               MDNS-SCAN(1)



NAME
       mdns-scan - Scan for mDNS/DNS-SD services published on the local
       network


SYNOPSIS
       mdns-scan


DESCRIPTION
       mdns-scan is a tool for scanning for mDNS/DNS-SD published services on
       the local network. It issues a mDNS PTR query to the special RR
       _services._dns-sd._udp.local for retrieving a list of all currently
       registered services on the local link.


OPTIONS
       mdns-scan has no commandline options.


NOTES
       mdns-scan is not a good mDNS citizen since it queries continuously for
       services and doesn't implement features like Duplicate Suppression. It
       is intended for usage as a debugging tool only.

       mdns-scan is incomplete since it doesn't resolve mDNS services for you
       - it just dumps their PTR RRs. To understand these records you need
       minimal knowledge of DNS-SD and how it works.

       mdns-scan does not terminate on its own behalf. It scans for services
       continuously until the user kills it by pressing C-c.

       mdns-scan does not rely on a local mDNS responder daemon. It has no
       dependencies 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
       scans for DNS-SD registered services, nothing else.
