Thanks for your answer. i had ever added linelog under accounting section. I'm gonna check if my NAS sends accounting packets by tcpdumping port 1813 on my server.

I'm focusing on accounting data. The filename is linelog under logdir. I create linelog under /var/log/radius/linelog myself with rights 644. . When i run freeradius, there is no data filled under after a sucessful authentification and connection. Do i miss something ?Are there any things to do to ? Here is linelog on attached file. You listed linelog in the accounting section of the default server right? Have you verified your NAS is actually sending accounting packets? -Arran - List info/subscribe/unsubscribe?
