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.
- -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.
- 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.
- For a query, after all currently known services are reported, exit.
- Generate debugging output. Specifying more than once increases the output.
- 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.
