Radius Configuration Files

This chapter describes the configuration files used by GNU Radius package.

These files are normally found in /usr/local/etc/raddb directory, which is defined at configuration time, although their location can be specified at runtime. In the discussion below we will refer to this directory by `raddb'. See section Naming Conventions.

• nastypes file: Information about how to query the NASes about active user sessions.
• hints file: Important user information that is common for the users whose names match some pattern.
• huntgroups file: Group users by the NAS (and, possibly, a port number) they come from.
