networkhotplug

The networkhotplug object can be used to generate events when a network interface becomes available or unavailable. A networkhotplugevent will be generated, indicating the interface and whether it was attached or detached.

Reconfiguring a network interface may cause it to detach and attach again. A DHCP address renewal may cause an event, even if the IP address hasn't changed.

networkhotplug IDL

interface NetworkHotplugEvent {
    attribute String type;
    attribute bool attached; // 1 -> attached, 0 -> detached
    attribute String interfaceName;
};

callback NetworkHotplugEventCallback = void (NetworkHotplugEvent event);

interface NetworkHotplug {
    void addEventListener(String type, NetworkHotplugEventCallback callback);
    void removeEventListener(String type, NetworkHotplugEventCallback callback);
};

Event Creation

To create a networkhotplug event, load the @brightsign/networkhotplug module using the Node.js® require() method:

let networkhotplugClass = require("@brightsign/networkhotplug");
let networkhotplug = new networkhotplugClass();

NetworkHotPlug

Use this interface to configure a networkhotplug event.

networkhotplugevent: This event is raised when the hotplug status changes. Use the addEventListener() method to listen for this event, or the removeEventListener() method to remove an event listener.

NetworkHotPlugEvent Properties

type string: Add or remove an event listener when this type of event occurs.
attached bool: Can be true or false (1 is attached, 0 is detached)
interfaceName string: Returns the interface name (for example, "eth0")

Example

let networkhotplugClass = require("@brightsign/networkhotplug");
let networkhotplug = new networkhotplugClass();

networkhotplug.addEventListener("networkhotplugevent", onNetworkHotplugEvent);    

function onNetworkHotplugEvent(data) {
  if (data.attached)
{     // connected on 'data.interfaceName'   }
}
