Thanks for the fast reply.

Yes, the server requires to receive the heartbeats in every 10 seconds.

Let me write an example. It's based on a wireshark capture.

  1. The server listens on 4 ports 8020, 8019, 8008, 8003. These ports are reserved (this is a switch online all the time, it doesn't really matter I think).
  2. The client sends the first heartbeat from ports: 53036, 53037, 53038, 53039 to ports 8020, 8019, 8008, 8003. This repeats in every 10 seconds.
  3. When server receives them replies from ports 8020, 8019, 8008, 8003 to ports 53036, 53037, 53038, 53039.
  4. If there are test results ready on the server it sends them to ports 53036, 53037, 53038, 53039.

If possible I would like / have to write a single client.
