gmdns - Man Page

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] [--timeout time_in_msecs] [-d|--debug] [-h|--help]

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

-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.

--timeout time

The amount of time to wait, in milliseconds, before closing everything and terminating.

-d|--debug

Generate debugging output.  Specifying more than once increases the output.

-h|--help

Help output

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.

gensio_mdns(3), regex(7), glob(7)

None.
