I cannot find any pattern, so I do not believe it to be a client side issue.
It's always an issue with the client, WiFi, or AP. It's not an issue with FreeRADIUS. Why? All of the EAP is driven by the client.
Of course, one can argue to ignore the warning as it works most of the time, but I do not like indeterministically behaving IT systems, hence it preys on my mind.
Has anybody an idea what the reason might be? If anybody wants to see a full debug output or a tcpdump, I can provide you with plenty of that. But I could not find anything.
You won't see it in a tcpdump. The *non* continuance of the EAP session is what FreeRADIUS is complaining about. tcpdump won't show you any more. Look on the client and/or the AP for the problem. Alan DeKok.
