GNU Radius is a server for remote user authentication and accounting and a set of accompanying utilities.
Radius is useful in a wide variety of applications from dial-up user services to voice-over IP systems. It is designed to handle ISP workloads, and can be scaled for any network that needs a centralized authentication and/or accounting service for its workstations.
Radius’ built-in extension language, Rewrite, enables users to write special-case rules for parsing and restructuring non-standard terminal server packets.
Features include:
- Supports a wide variety of authentication schemes:
- User supplied authentication data via answering terminal server login/password prompts.
- PAP or CHAP protocols.
- System or internal database storage of user’s personal data.
- SQL or PAM authentication.
- Three built-in accounting schemes:
- Unix accounting.
- Plain text Detailed accounting.
- SQL accounting.
- Communicates with MySQL and PostgreSQL servers. Other DBMS are supported via ODBC interface.
- Fully extensible with support for two extension languages: Rewrite and Scheme.
- SNMP management.
