  That's good.

> Yesterday I got a complaint from a foreign user, he didn't get wifi service with his usual settings. I looked for the logs under radacct/ in the folder with the IP of the NAS. I have 'auth-detail', 'pre-proxy', 'post-proxy' and 'reply-detail'. I was able to find logs of his packages in auth-detail and pre-proxy, but was unable to find out if I got any reply. I can link logs of packets between 'auth-detail' and 'pre-proxy', and also between 'post-proxy' and 'reply-detail', but I couldn't find a way to see which reply-detail packets correspond to any one in auth-detail. Is that possible? If yes, how?

  Look at User-Name / Calling-Station-ID.  They should be pretty unique.

$ man raddebug

  You can do some debugging while the server is live.
