====== SMRadius ======

Current project: https://wiki.smradius.org/

===== Purpose =====

High performance feature rich radius server.

===== Features =====

  * Database independent design: MySQL, PostgreSQL, Oracle, SQLite3
  * Replicated database support
  * Custom database queries allowing usage of returned results as macros

  * mod_auth_pap: PAP (RFC1334)
  * mod_auth_chap: CHAP (RFC1944)
  * mod_auth_mschap: MSCHAPv1 & MSCHAPv2, incl. MPPE (RFC2443, RFC2759, RFC2548, RFC3079)

  * Vendor specific attributes (RFC2865, RFC2866)
  * Supported attribute operators include =, :=, ==, +=, !=, >, >=, <, ⇐, =~, !~, =*, !*
  * Extended Radius Practices:
    * Packet of disconnect (RFC2882)
    * CoA (RFC3576)

  * Service provider control panel, including WiSP customizations
  * Client control panel for viewing usage and plan details

  * Data & time based capping
  * Prepaid users
  * Topups
  * Account validity periods, including valid start and end dates
  * Prepaid accounting based on usage/time
  * Creation of accounting START records when no START record has been received but an interim update has - helps on slow/lossly links
  * Bandwidth multipliers that can be added to radius clients, user groups or users
  * Auto-Topups with customizable notification templates per client, realm, user group or user

  * Plugin: Notifications, % based or approximate time based
  * Radius proxy - with filtering of requests/values … etc in both directions + adding items. Persistent storing of radius items so inbound from client NAS is stored and sent back with accounting packet.
  * Port 1700 proxy back to NAS
  * Plugin: User denylists
  * Plugin: Grouping of users and usage caps
  * Radius proxy - enhancement: round-robin & random proxy destination tries, easy backoff
  * Backstore logs for if proxy destinations go down
  * Redis support
  * Database load balancing
  * IP Pools (in database)

===== Technologies =====

  * Python
  * Flask
  * Possibly C network event engine
  * [[..:topagex:start]]

===== TODO =====

  * Reverse engineer what we currently have in Perl and create something more flexible
