Hi,

I had a read of the RATP spec at https://www.rfc-editor.org/rfc/rfc916

The goal is to detect one end trying to start a fresh connection while another
is established but manages to be a bit too broad by specifying that any SYN
is an error rather than a SYN without an ACK.

There seems to be two solutions here:

- Don't re-send SYN packets
- Break the spec and check if ACK is set before terminating the connection

John.
