I ran a tcpdump against a customer IP sending us accounting packets. When reviewing in Wireshark I can see a (small) percentage of packets that do not show any Accounting-Response reply, and then a few seconds later the NAS re-sends and then we reply as expected. So something on the home server itself is not right, it seems to 'miss' incoming packets.
It's usually a slow database.
I ran the server in debug mode at the same time as the capture and the first packet did not even show up at all, as if the server never received it. But, the packet was received by the server as per the wireshark capture file.
If the OS doesn't deliver packets to FreeRADIUS, then there's little you can change in FreeRADIUS to fix the problem. Alan DeKok.
