File: server.go Progetto: Tsingson1988/arp

// ListenAndServe listens for ARP requests using a raw ethernet socket on the
// network interface specified by s.Iface.  Serve is called to handle serving
// traffic once ListenAndServe opens a raw ethernet socket.
func (s *Server) ListenAndServe() error {
	p, err := raw.ListenPacket(s.Iface, raw.ProtocolARP)
	if err != nil {
		return err
	}

	return s.Serve(p)
