Functions ¶
func BasicDiscovery ¶ added in v1.6.2
func BasicDiscovery(service string, onentry func(*ServiceEntry) bool) error
BasicDiscovery - default golang Multicast UDP listener. Does not work well with multiple interfaces.
func Discovery ¶
func Discovery(service string, onentry func(*ServiceEntry) bool) error
Discovery - better discovery version. Works well with multiple interfaces.
func InterfacesIP4 ¶ added in v1.6.2
func NewDNSAnswer ¶ added in v1.7.0
func QueryOrDiscovery ¶ added in v1.6.2
func QueryOrDiscovery(host, service string, onentry func(*ServiceEntry) bool) error
QueryOrDiscovery - useful if we know previous device host and want to update port or any other information. Will work even over VPN.
func Serve ¶ added in v1.7.0
func Serve(service string, entries []*ServiceEntry) error
func SetsockoptIPMreq ¶ added in v1.6.2
Types ¶
type Browser ¶ added in v1.6.2
type Browser struct {
Service string
Addr net.Addr
Recv net.PacketConn
Sends []net.PacketConn
RecvTimeout time.Duration
SendTimeout time.Duration
}
func (*Browser) Browse ¶ added in v1.6.2
func (b *Browser) Browse(onentry func(*ServiceEntry) bool) error
func (*Browser) ListenMulticastUDP ¶ added in v1.6.2
ListenMulticastUDP - creates multiple senders socket (each for IP4 interface). And one receiver with multicast membership for each sender. Receiver will get multicast responses on senders requests.
func (*Browser) Serve ¶ added in v1.7.0
func (b *Browser) Serve(entries []*ServiceEntry) error
type ServiceEntry ¶
type ServiceEntry struct {
Name string `json:"name,omitempty"`
IP net.IP `json:"ip,omitempty"`
Port uint16 `json:"port,omitempty"`
Info map[string]string `json:"info,omitempty"`
}
func NewServiceEntries ¶ added in v1.7.0
func NewServiceEntries(msg *dns.Msg, ip net.IP) (entries []*ServiceEntry)
func Query ¶ added in v1.6.2
func Query(host, service string) (entry *ServiceEntry, err error)
Query - direct Discovery request on device IP-address. Works even over VPN.
func (*ServiceEntry) Addr ¶
func (e *ServiceEntry) Addr() string
func (*ServiceEntry) Complete ¶
func (e *ServiceEntry) Complete() bool
func (*ServiceEntry) Host ¶ added in v1.7.0
func (e *ServiceEntry) Host(service string) string
func (*ServiceEntry) String ¶ added in v1.7.0
func (e *ServiceEntry) String() string
func (*ServiceEntry) TXT ¶ added in v1.7.0
func (e *ServiceEntry) TXT() []string
