Using legacy plugins


Legacy type plugins are located in the following location:


And contain files with the extension “.inc”.

All automatically registered functions start with the name of the file (without the extension), followed by the purpose. For example vpn_configure would be the configure handle in a plugin file name


To register services, the <plugin>_services() function should return a structure containing its name, description and operating properties.

function myplugin_services()
    $service = array();
    $service['name'] = 'myservice';
    $service['description'] = gettext('My service');
    $service['configd']['restart'] = array('myservice restart');
    $service['configd']['start'] = array('myservice start');
    $service['configd']['stop'] = array('myservice stop');
    $services[] = $pconfig;
    return $services;

To register syslog targets, the <plugin>_syslog() function should return a structure containing targets and definitions.

function myplugin_syslog()
    $logfacilities = array();
    $logfacilities['myplugin'] = array(
        'facility' => array('myplugin'),
        'remote' => 'myplugin',
    return $logfacilities;


To register new (virtual) interfaces, create a function called <plugin>_interfaces(), which should return a named array containing the unique interface name as key (enc0 for ipsec for example).

Every item should contain the following properties:

Property Syntax Description
enable boolean interface enabled, if so it will be saved in the config
descr text User readable description
networks array, [network, mask] list of named arrays containing remote networks
type text “none”
if text physical interface (e.g. enc0)
virtual boolean Virtual interface, true/false


function myplugin_interfaces()
    global $config;

    $interfaces = array();
    if (isset($config['myplugin']['enable'])) {
        $oic = array("enable" => true);
        $oic['if'] = 'tun0';
        $oic['descr'] = 'myplugin';
        $oic['type'] = "none";
        $oic['virtual'] = true;
        $oic['networks'] = array();
        $interfaces['tun0'] = $oic;

    return $interfaces;


When your plugin needs configuration after boot, you can create a function called <plugin>_configure() which will be called upon boot.
