    How to Make SSH Service Discoverable in Elixir Using mDNS?

    To make service discoverable we need following services registered:

      # create domain for an ip
      %Mdns.Server.Service{domain: "somedomain.local", data: :ip, ttl: 450, type: :a},
      # make service discoverable
      %Mdns.Server.Service{domain: "_services._dns-sd._udp.local",data: "_ssh._tcp.local",ttl: 4500, type: :ptr},
      # register ssh service
      %Mdns.Server.Service{domain: "_ssh._tcp.local",data: "SOME NAME._ssh._tcp.local",ttl: 4500, type: :ptr},
      # point service to our domain and port (22)
      %Mdns.Server.Service{domain: "SOME NAME._ssh._tcp.local",data: {0,0,22, 'somedomain.local'},ttl: 4500,type: :srv},
      # empty txt service (some tools expext that)
      %Mdns.Server.Service{domain: "SOME NAME._ssh._tcp.local",data: [],ttl: 4500,type: :txt})
    ] |> Enum.each(&Mdns.Server.add_service/1)
