NAME

       radius.conf - Configuration for nnrpd RADIUS authenticator

DESCRIPTION

       This describes the format and attributes of the configuration file for
       the nnrpd RADIUS authenticator.  See radius(1) for more information
       about the authenticator program.  The default location for this file is
       radius.conf in pathetc.

       Blank lines and lines beginning with "#" are ignored, as is anything
       after a "#" on a line.  All other lines should begin with a parameter
       name followed by a colon and the value of that key, except that each
       section of configuration for a particular server should be enclosed in:

           server <name> {
               # parameters...
           }

       where <name> is just some convenient label for that server.

       The available parameters are:

       radhost
           The hostname of the RADIUS server to use for authentication.  This
           parameter must be set.

       radport
           The port to query on the RADIUS server.  Defaults to 1645 if not
           set.

       lochost
           The hostname or IP address making the request.  The RADIUS server
           expects an IP address; a hostname will be translated into an IP
           address with gethostbyname().  If not given, this information isn’t
           included in the request (not all RADIUS setups require this
           information).

       locport
           The port the client being authenticated is connecting to.  If not
           given, defaults to 119.  This doesn’t need to be set unless readers
           are connecting to a non-standard port.

       secret
           The shared secret with the RADIUS server.  If your secret includes
           spaces, tabs, or "#", be sure to include it in double quotes.  This
           parameter must be set.

       prefix
           Prepend the value of this parameter to all usernames before passing
           them to the RADIUS server.  Can be used to prepend something like
           "news-" to all usernames in order to put news users into a
           different namespace from other accounts served by the same server.
           If not set, nothing is prepended.

       suffix
           Append the value of this parameter to all usernames before passing
           them to the RADIUS server.  This is often something like
           "@example.com", depending on how your RADIUS server is set up.  If
           not set, nothing is appended.

       ignore-source
           Can be set to "true" or "false".  If set to false, the RADIUS
           authenticator will check to ensure that the response it receives is
           from the same IP address as it sent the request to (for some added
           security).  If set to true, it will skip this verification check
           (if your RADIUS server has multiple IP addresses or if other odd
           things are going on, it may be perfectly normal for the response to
           come from a different IP address).

EXAMPLE

       Here is a configuration for a news server named news.example.com,
       authenticating users against radius.example.com and appending
       "@example.com" to all client-supplied usernames before passing them to
       the RADIUS server:

           server example {
               radhost: radius.example.com
               lochost: news.example.com
               secret: IamARADIUSsecRET
               suffix: @example.com
           }

       The shared secret with the RADIUS server is "IamARADIUSsecRET".
