RADIUS protocol

Example:

-module(server).

-behaviour(radius_service).

-export([start/0, stop/0, handle_request/3]).

-include("radius.hrl").

-define(SERVICE_NAME, test_radius_server).

start() ->
    application:start(radius),
    lists:foreach(fun radius_dict:add/1, radius_dict_file:load("dictionary")),
    Nas1 = #nas_spec{name = nas1, ip = {127,0,0,1}, secret = "testing123"},
    Nas2 = #nas_spec{name = nas2, ip = {10,10,0,1}, secret = "testing123"},
    ServiceOpts = [
        {ip, {0,0,0,0}},
        {port, 1812},
        {callback, ?MODULE}
    ],
    radius:start_service(?SERVICE_NAME, ServiceOpts),
    radius:add_client(?SERVICE_NAME, Nas1),
    radius:add_client(?SERVICE_NAME, Nas2).

stop() ->
    radius:stop_service(?SERVICE_NAME).

handle_request(Type, Request, Client) ->
    io:format("Type: ~p~nRequest: ~p~nClient: ~p~n", [Type, Request, Client]),
    Response = #radius_packet{code = ?ACCESS_ACCEPT, attrs = []},
    {ok, Response}.
