Australian company Open System Consultants Pty Ltd has released Radiator, a flexible and extensible RADIUS Server that works with a wide variety of user databases, authentication methods and computer platforms. RADIUS (Remote Authentication Dial In User Service) is now the most frequently used method for authenticating network access at Internet Service Providers (ISPs).

Whenever a user dials in to an ISP, it’s probably a RADIUS server that checks if they are a paid-up customer, and if password is correct. Global Internet roaming uses a cooperating network of RADIUS servers so users can log in at any ISP around the world.

For an ISP, their RADIUS server is a critical component for customer service, billing and management, and Open System Consultants offers the most flexible and feature-packed RADIUS server available anywhere.

OSC’s Radiator RADIUS server authenticates users from flat files, DBM files, SQL and ODBC databases, LDAP, NT User Manager, GRIC, iPASS and legacy systems and databases. It also stores accounting details in standard RADIUS file format, SQL databases or wtmp files. Adding new authentication methods is easy, and full source code is provided so that ISPs can customise it to do exactly what they need.

Radiator also works closely with the popular ISP billing packages Platypus from Boardtown, and Emerald from IEA, allowing ISPs to easily manage their user population and their login privileges.

Radiator is unique in handling multiple RADIUS realms, each with their own authentication methods and databases. Very large numbers of users can be handled without compromising performance.

Radiator runs on all known varieties of Unix, Windows 95, 98, NT and 2000, plus MacOS X, which makes it highly portable in the face of changing and upgrading computer hardware. Radiator’s features make it suitable for use in any ISP, large or small, new or existing. Using Radiator, a new ISP can start out with a simple flat file or NT user database, and grow to a very large and sophisticated SQL based user management, accounting and administration system, all without the disruption of changing RADIUS servers. With Radiator, ISPs can also participate in Global Roaming schemes like GRIC and iPASS, allowing them to sell access to other organisations, or for their users to dial in from anywhere in the world.
