Hi All,

We are evaluating whether we can use FreeRadius as a RADIUS server cum GPRS subscriber database(using MYSQL).There are these queries which we have and hence I am seeking your help --- 1>What is the rate of RADIUS msgs that FreeRadius can handle? 2>What needs to be done if we want to write handlers for START/STOP/Interim Update acct msgs?The handlers would basically extract info of the corresponding subscriber(framed-IP) from the mySQL database and send out radius response. 3>On receiving STOP msg from NAS,can FreeRadius send out notification to a particular IP?Any event handling capability existing?

Hi Sourav I have had FreeRADIUS deployed at a large GSM/GPRS operator for 3 years now without any problems. I am using PostgreSQL my configuration which is documented in the wiki would need to be modified to work with MySQL. I highly recomend you use PostgreSQL unless there is a particular requirement for MySQL as it is in my experience much more reliable, and generally speaking more "correct" which is what you want when you are dealing with billing records. My setup is running on original, low end SunFire Opteron servers and until I updated my kernel a month ago they had been running without reboot for almost 700 days.. They happily handle GGSN restarts which generate connection floods of thousands of radius requests per second.. Regards -- Peter Nixon http://peternixon.net/
