Hi ! Sorry, but I can not find the answer to the question - what the external (for example php script) should return to the radius server at accounting? What attributes? I'm use - FreeRADIUS Version 2.2.6, for host x86_64-redhat-linux-gnu, built on Sep 22 2015 at 15:27:25 In Radius log: Fri Jan 15 20:59:12 2016 : Info: Ready to process requests. rad_recv: Accounting-Request packet from host 1.1.4.4 port 62311, id=8, length=32 Acct-Status-Type = Start Acct-Session-Id = "8768" Fri Jan 15 20:59:54 2016 : Info: # Executing section preacct from file /etc/raddb/sites-enabled/mclaut_default_exec Fri Jan 15 20:59:54 2016 : Info: +group preacct { Fri Jan 15 20:59:54 2016 : Info: ++[preprocess] = ok Fri Jan 15 20:59:54 2016 : Info: [bill_acc] expand: %{hex:Attribute} -> Fri Jan 15 20:59:54 2016 : Info: [bill_acc] expand: %{Acct-Session-Id} -> 8768 Fri Jan 15 20:59:54 2016 : Info: [bill_acc] expand: %{Acct-Authentic} -> Fri Jan 15 20:59:54 2016 : Info: [bill_acc] expand: %{Acct-Status-Type} -> Start Fri Jan 15 20:59:54 2016 : Info: [bill_acc] expand: %{NAS-IP-Address} -> 1.1.4.4 Fri Jan 15 20:59:54 2016 : Info: [bill_acc] expand: %{User-Name} -> Fri Jan 15 20:59:54 2016 : Info: [bill_acc] expand: %{NAS-Port} -> Fri Jan 15 20:59:54 2016 : Info: [bill_acc] expand: %{Framed-Protocol} -> Fri Jan 15 20:59:54 2016 : Info: [bill_acc] expand: %{Framed-IP-Address} -> Fri Jan 15 20:59:54 2016 : Info: [bill_acc] expand: %S -> 2016-01-15 20:59:54 Fri Jan 15 20:59:54 2016 : Debug: Exec output: Fri Jan 15 20:59:54 2016 : Info: [bill_acc] Exec: program returned: 0 Fri Jan 15 20:59:54 2016 : Info: ++[bill_acc] = ok Fri Jan 15 20:59:54 2016 : Info: +} # group preacct = ok Fri Jan 15 20:59:54 2016 : Info: WARNING: Empty accounting section.

I do not understand - WARNING: Empty accounting section. Using default return values.
