We are currently testing Freeradius + MySQL on Centos 6 x64 using Mikrotik as a client. Basic testing with the RadCheck and RadReply is working fine i.e. simultaneous logins, rate limits. We are now looking to implement data limits and additional data bundles.
Having searched google for days for some guides on how to do this I have come up blank. If someone could point me in the right direction on how to config rlm_sqlcounter etc it would be very useful.
