bool radius_add_server ( resource radius_handle, string hostname, int port, string secret, int timeout, int max_tries )
radius_add_server() may be called multiple times, and it
may be used together with radius_config(). At most 10
servers may be specified. When multiple servers are given, they are tried
in round-robin fashion until a valid response is received, or until each
server's max_tries limit has been reached.
The hostname parameter specifies the server host,
either as a fully qualified domain name or as a dotted-quad IP address
in text form.
The port specifies the UDP port to contact on
the server. If port is given as 0, the library looks up the
radacct/udp service in the
network services database, and uses the port found there. If no entry
is found, the library uses the standard Radius ports, 1812 for
authentication and 1813 for accounting.
The shared secret for the server host is passed to the
secret parameter. The Radius protocol ignores
all but the leading 128 bytes of the shared secret.
The timeout for receiving replies from the server is passed to the
timeout parameter, in units of seconds.
The maximum number of repeated requests to make before giving up is
passed into the max_tries.
