NAME

       gmdns - Tool for doing mDNS operations

SYNOPSIS

       gmdns   [-n|--name   str]   [-t|--type  str]  [-m|--domain  str]  [-o|--host  str]  [-i|--interface  num]
       [-y|--nettype  unspec|ipv4|ipv6]  [-s|--service]  [-x|--txt  str]  [-p|--port  num]  [-c|--close-on-done]
       [-d|--debug] [-h|--help]

DESCRIPTION

       The  gmdns  program  allows  you  to  advertise  an  mDNS service or query for mDNS services on the local
       network.

OPTIONS

       -n|--name str
              The name field for the service/query.

       -t|--type str
              The type field for the service/query.

       -m|--domain str
              The domain field for the service/query.

       -o|--host str
              The host field for the service/query.

       -i|--interface num
              The interface number for the service/query.  If  -1,  service/query  all  the  interfaces  on  the
              system.  Defaults to -1.

       -y|--nettype unspec|ipv4|ipv6
              The  network  type  for  the  service/query.   If  unspec, the service/query is for IPv4 and IPv6.
              Otherwise it's only for the specified protocol.  Defaults to unspec.

       -s|--service
              Advertise a network service instead of doing a query.  In this case,  the  name,  type,  and  port
              options  must  be  provided.   The  others are optional and should not be provided unless you need
              them.

       -x|--txt str
              Add the string to the set of text strings advertised for a service.  Only makes sense with -s.

       -p|--port str
              Use the given port for the advertised service.  Only make sense with -s.

       -c|--close-on-done
              For a query, after all currently known services are reported, exit.

       -d|--debug
              Generate debugging output.  Specifying more than once increases the output.

       -h|--help
              Help output

STRING VALUES FOR QUERIES

       The string values for queries may use regular expressions or globs.  If the string starts with '%',  then
       the  data after it is treated as a regular expression and fields are matched against that.  If the string
       starts with '@', the the data after it is treated as a standard glob.  See the regex(7) and  glob(7)  man
       pages for details.

       If the string starts with '=', an exact comparison is done with the data after it.

       If  the  string  starts  with  a-z0-9_ or a space, then an exact string comparison is done, including the
       first character.

       The behavior of matching for any other starting character is undefined.  In general,  you  should  always
       use '@', '%', or '=' as the starting character of all your query strings to be sure.
