I found out that the ARP changes were not the culprit. The problem was that the enumeration of ethernet interfaces changed once again between 2.6.3 and 2.6.4. Therefore the IP addresses were assigned to the wrong interfaces and thus the hosts for which ARP sent requests were attached to different network segments, so that no replies came in. *Sigh*. Up to now I've seen 3 different enumeration schemes for network interfaces in 2.4.x, 2.6.x (x < 4) and 2.6.4. I guess for our machine with 4 interfaces I'll only have to go through this 21 more times before we've tried all possibilities. DaveM, can we not find a better solution to this? Or should I look up interface names by MAC address in the future? Best regards, -Udo.
