 new Thread(() -> {
 try {
 this.handle.loop(-1, (packetHeader, rawPacket) -> {
 try {
 Packet packet = new Packet();
 packet.decode(rawPacket, datalink);
 System.out.println(packet);
 dumper.dump(packetHeader, rawPacket);
 dumper.flush();
 } catch (LayerDecodeException | PcapException e) {
 e.printStackTrace();
 }
