NWS 40 FreeRADIUS Demystified

18 August 2014 at 2:58pm

Dr Alan Buxey's 2012 FreeRADIUS Demystified seminar presentation


  • Examining the RADIUS packet flow - using the facility of FR to create virtual servers which can be dedicated to each of the three key requisite functions of an ORPS, not only can the the flow and processing of RADIUS packets can be easily understood, but by tuning each virtual server for the task. performance can be optimised. 
  • Best Current Practice (BCP) - 'how to' for eduroam
  • FreeRADIUS 3 - what's new, major changes in features and methods, where files have moved to, config files layout changes [Note - this relates to release 3.0.0, many of the notes are not appplicate to the latest 3.0.3 release]

Nb. The ppt includes many useful and explanatory diagrams:

  • FreeRADIUS packet flows and interconnects inside and between virtual servers
  • 802.1X and EAP packet exchange sequence (again)
  • Authentication flow chart for a Home auth when user is on home campus (which modules are doing what in each VS)
  • Authentication flow chart for handling a Visiting user to a campus
  • Authentication flow chart for a Home site handling an auth request (arriving via the NRPS) from a remote site
