I configured my NAS to send accounting update per one minute. In /var/log/freeradius/radacct/(ip of the nas)/detail-(date), I can read a txt file where some accounting infos are written but when I issue "radwho" command, I can not see anything but the titles for non-written accounting details.

   Read the debug output, and look for the “radutmp” module.  What does it say when the server receives an  Accounting-Request?

  The point is to read the output *after* it says “Ready to process requests”.  That tells you what it’s doing when it processes requests.

Unfortunately, my server got disfunctioned when I had tried to configure it for active directory authentication. I could only recovered it by re-installing then I lost and forgot what I did to use radwho.

  You should use “git” for revision control on the raddb directory.  It helps a lot.

  If you send Accounting packets which have useful session data in them, radwho will “just work”.
