Accounting with external script

[mclaut at mclaut.com]

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.

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


But, answer from script:

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

And NAS don't recieve any answers from Radius Server....

Tell me please, what am I doing wrong?

Thank you in advance
