Ack! I've had horrid problems like that before now; Astaro Security Linux
picked the wrong driver for a NIC I have that should use the fealnx driver.
Symptoms were that UDP and ICMP worked, but TCP didn't because the TCP
checksum got messed up (IIRC, that was the behaviour, anyway).

At first, I thought my sniffer (ethereal - feature rich, but I'm not
entirely confident of its quality in places) was calculating the checksums
wrongly and ignored the packets being reported with broken checksums!

The question is; did you /want/ to? ;-)
