Hello Alan,

Thank you for you quick answer. Sorry again, for contacting you
directly,
I unfortunately read the linux-kernel faq yesterday night only.

here's the tcpdump output taken with kernel 2.4.4 and kernel 2.2.18
both from SuSE distribution, Versionm 7.2 and 7.1 respectively.
2.2.18 didn't show the double ack, 2.4.4 does.

I include some C-source that I used to track that down.
The programm only connect()s, sleeps(10) and close()s.

Hope that helps to isolate the bug. Port 7 (echo) appeared to be quite
nice for this trace, since no application uses it, so it's easy to grep
with
tcpdump.

kind regards from Germany.
Linux is used here too - I bet you knew already.
Thanks to you and Linus and the whole community for that great OPERATING
SYSTEM.

Bernhard.
