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.
