Thanks for the explanations. Now it makes sense.

Hi SYN-bit IP TTL is the same for PSH, ACK and the RST (127ms) I can find delta between previous PSH and RST from 1ms u

Hi
I have communication between a Linux and windows system. Don't have info about rooters/switches/firewall between.

The communication runs perfect, but out of the blue it send a RST. I trace both sides at the same time and try to understand why I receive a RST, which is not found in the trace file of the other side:

I receive on a Linux system [RST] Seq=xxx which is not in the trace of the windows system. Under Acknowledgment number yyy I have the ExpertInfo: The acknowledgment number filed is nonzero while the ACK flag is not set.

Would be great if somebody can give some advice how to proceed.

Thanks

Beat

Example

  • Everything is running normal
  • Then server-socket (Linux) sends client-socket (Windows) PSH, ACK <==is expected
  • 8ms later client-socket (windows) sends RST --> server-socket (Linux)
  • This RST can be found only in the Linux trace. Not in the windows trace

Hi Jaap I added an example. Do I understand you correct: A router/switch/firewall modifies messages? I would say this is
