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".
