radiusd8

Remote authentication dial in user service (radius) daemon

Linux OpenBSD

Usage

radiusd [-dn] [-f file]

Overview

The radiusd daemon implements the RADIUS protocol.

To have radiusd enabled at boot time, use “rcctl enable radiusd”, which sets

radiusd_flags=""

in rc.conf.local(8).

The options are as follows:

-d: Do not daemonize, log to stderr instead of syslog(3), and produce some additional debugging output.
-f file: Specify an alternative configuration file.
-n: Configtest mode. Only check the configuration file for validity.

Files

/etc/radiusd.conf: Default configuration file.
