Hi all, I am using freeradius server on my AWS. Freeradius version : 2.2.8 on 64bit system installed it via package manager. I have tried to go through a few times over the online present materials for freeradius but still I am not able to wrap my head around NAS. Here is my picture & current understanding: *Wireless AP* : D link 850l ; WPA-enterprise is only on 5 GHz band. The router firmware gives me this flexibility to put different security provisions on 2.4 and 5.0 GHz spectrum. AWS instance : *freeradius* server running. radtest output is correct as I can see by username and password being authenticated by access-accept response. 1. One of my node i.e laptop/mobile phone tries to connect to my wireless access point at 5.0 GHz. 2. I recieve packets at my freeradius server as I see it by running with -X swtich. 3. Successfull authentication is done and my device is connected. The problem arises for me when there occurs no accounting packets, the radacct table is empty all along. As what I think I understand by reading materails over internet, it seems like NAS sends this which I probably was considering my router to be. Is my d-link 850l is NAS? or I am getting it all wrong? There are no accounting packets, I checked it with radsniff. I am attaching a very big output response from my free-radius output. Initial few attempts are done while I tried connecting from my android phone to wireless AP with wrong credentials. Line number 1890 is when I sent request with correct credentials. Also, attaching my default file under sites-enabled/. I understand that I am here asking two things but I guess thats how I come to know about the problem. Let me know if any other outputs or logs are required. -- Regards, saurabh shandilya www.embedded4fun.com https://in.linkedin.com/in/shandilyasaurabh
