OpenRADIUS – RADIUS server

Last Updated on July 16, 2023

OpenRADIUS is a RADIUS server that links your network access devices to your user-, service profile-, and usage databases.

OpenRADIUS has a powerful external module interface that uses pre-spawned subprocesses and pipes for communication, allowing you to implement modules in any language that supports Unix pipe I/O. Its behaviour is fully configurable, using a simple built-in language that gives you full control over the request and reply list.

It includes versatile LDAP and SQL modules, a full featured RADIUS client, and a fully functional example configuration for metered pre-paid accounts.

Features include:

• Ability to get shared secrets, authentication information, policies and user profiles from any available external data source.
• Support for password databases, including NIS/NIS+, Livingston-style ASCII files, LDAP directories and SQL databases out of the box.
• Fully customizeable authentication schemes and security policies, using a built-in business rule language.
• Simple, scalable and fully documented module interface. Modules may supply data such as user information, and may also store data such as logging and accounting.
• Modules can be written in any language that supports ASCII or binary Unix pipe I/O.
• The interface allows multiple module subprocesses to be started for each data source, allowing modules to be single-threaded while retaining support for multiple concurrent requests to the same data source.
• Flexible dictionary that can be made to support any type of non-standard vendor-specific attribute, including multiple attributes inside the same VSA, non-standard attribute IDs or length fields, subfields, and much more.
• Binds to a single or multiple IP addresses/network cards, and listen on multiple ports.
