network-config

Network configuration for NodeJS. Only used & tested on Debian

Setup

npm install network-config

Usage

List active interfaces

To check the state of dhcp you have to enable parsing the interfaces file.

var network = require('network-config');

network.interfaces(function(err, interfaces){
  /* interfaces should be something like:

  [{
    name: 'eth0',
    ip: '1.1.1.77',
    netmask: '1.1.1.0',
    mac: 'aa:aa:aa:aa:aa:aa',
    gateway: '10.10.10.1', 
   },
   { ... }, { ... }]
  */
 
});

network.interfaces(function(err, interfaces){
  /* interfaces should be something like:

  [{
    name: 'eth0',
    ip: '1.1.1.77',
    netmask: '1.1.1.0',
    mac: 'aa:aa:aa:aa:aa:aa',
    gateway: '10.10.10.1', 
    dhcp: false
   },
   { ... }, { ... }]
  */
 
}, {interfaces: {parse: true, file: '/etc/network/interfaces'}}); //default: parse: false, file: '/etc/network/interfaces'

// ipv6 support

network.interfaces(function(err, interfaces){
  /* interfaces should be something like:

  [{
      name: 'enxb827ebf6e3b1',
      ip: '192.168.10.10',
      ip6: 'fe80::2866:af76:5fd6:11e2',

    }, {

      netmask: null,
      broadcast: null,
      mac: "b8:27:eb:f6:e3:b1",
      gateway: '192.168.10.1'
    }]
  */
 
}, {gateway: {resolveHostNames: false, route6: true}});

Update interface (static)

network.configure('eth0', {
    ip: 'x.x.x.x',
    netmask:'x.x.x.x',
    broadcast: 'x.x.x.x',
    gateway: 'x.x.x.x',
    restart: true // (default) restart networking service right away
}, function(err){

})

Update interface (dhcp)

network.configure('eth0', {
    dhcp: true,
    restart: false // don't restart networking service
}, function(err){
});
