Unfortunately I have no way to ascertain that, but I do know it's running Debian. I would venture a guess that it's a series 2.2 kernel. I tried a nmap fingerprint, but it couldn't identify the kernel.

You have no problem with the reiceiver immediately acking PSH segments? Shouldn't we be robust against this kind of behaviour? [Otherwise a sender can force us into a permanent quickack mode simply by setting PSH on every segment.]
