Using FreeRadius for a HotSpot with a PrePaid Billing System

[Oswin Ondarza]

Hi everyone,   I am trying to  build a Hotspot system using FreeRADIUS,  I have a Colubris CN3000 NAS  and it works great with the FreeRADIUS, but now I need a billing system integrated to the FreeRADIUS  so  users when enter the hotspot can pay with credit card using the explorer/mozilla  to get  access or to get  login information.   I would like to build a complete open source solution, so the only prepaid billing system open source that I have found thar "could" be intergrated with the FreeRADIUS is   "FreeSide"   (http://www.sisd.com/freeside/)  but I haven't tried it yet, I would like to hear a little about this before doing it.     So, any Opinion ? Suggestions ?   is anybody tryng  the same solution ???     I hope someone can help me,   Thanks in advance !!!   Oswin.
