How to use Freeradius with traffic limit?

Hi, I'm running Freeradius 2.1+Postgresql 8.4.4+OpenVPN on Ubuntu 9.10 x86. It runs smoothly now, however, I want to know that if there is any way to limit per user's traffic, like 10G/month, and disconnect/reject their connection when the limitation has reached. It seems the the column AcctInputOctets and AcctOutputOctets is responsible for traffic calculation, how should I limit user's traffic by using these two? Thanks in advance. -- View this message in context: http://old.nabble.com/How-to-use-Freeradius-with-traffic-limit--tp28809968p2... Sent from the FreeRadius - User mailing list archive at Nabble.com.
