chilli-radius - Information about RADIUS in chilli




chilli uses RADIUS for access provisioning and statistics. Standards and best practices defined in RFCs are followed as best possible. However, chilli does take some liberties and bends the rules in places to better adapt to the more dynamic application of captive portals.
