RADIUS Server Authorization and Accounting - MY SQL Configuration - Please Help

[anusha mule]

Hi Prabhpal,

Thanks for your reply.


Yes, we have the setup-done with Free RADIUS and MySQL enabled.

With the users file and radacct table, we are able authenticate and log the
RADIUS accounting messages.



We have the User Polices based on Time and Data usage.



That is we want to limit the users based on their duration of access and
usage of data over a multiple session establishment.



Hence, kindly provide your valuable inputs to acheive this with Free RADIUS
- MySQL settings.





Note :



One thing is that - we read "sql_counter" module is useful to limit the
time a user can spend daily, weekly, or monthly on the network.

Has sql_counter has problems in limiting a user's data usage or accounting
the duration used in the each of the session establishment and provide the
access.





Thanks & Regards,

Anusha M
