Dear all, I 've almost reolved trouble. Indeed, i actived accounting on my nas to make acounting running. But i felt my nas or something else is bugged. When a connection is sucessful , i can see packets on port 1812 and 1813. But after 20 seconds, i see log accounting wich announced Acct-Status-Type = Stop Acct-Input-Octets = 18014 Acct-Output-Octets = 58987 Acct-Input-Packets = 190 Acct-Output-Packets = 98 Acct-Terminate-Cause = Lost-Service Acct-Session-Time = 16 In fact, i didn't lost connectivity because client is always there and running without trouble. So i want to understand something. For accounting packets, is this radius server who requets "accounting fields" to the NAs controller ? When a client is disconnected for any reasons, how does it warn Nas controller ?Does the Nas wontroller role to warn radius server when it looses a client ? Best regards.

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?
