arpscan

arpscanner

Simple arp-scan wrapper module

arp-scan sends ARP (Address Resolution Protocol) queries to the specified targets, and displays any responses that are received. It allows any part of the outgoing ARP packets to be changed, allowing the behavior of targets to non-standard ARP packets to be examined. The IP address and hardware address of received packets are displayed, together with the vendor details. These details are obtained from the IEEE OUI and IAB listings, plus a few manual entries. It includes arp-fingerprint, which allows a system to be fingerprinted based on how it responds to non-standard ARP packets.

Tested in Mac OSX 10.9.5 and Raspbian GNU/Linux 7 (wheezy).

NOTE: When running on Mac you don't need to sudo the command, you do have to sudo on your Raspberry Pi.

Getting Started

First you need to install arp-scan if is not already installed.

In Mac you can use brew:

brew install arp-scan

On Debian:

sudo apt-get install arp-scan

Install the module with: npm install arpscanner

Examples

To use the module programmatically:

var arpscanner = require('arpscanner');
arpscanner(onResult);

function onResult(err, data){
    if(err) throw err;
    console.log(data);
}

The output should be something similar to:

[ { ip: '192.168.1.1',
    mac: 'AC:CF:23:31:9B:FC',
    vendor: 'Cisco-Linksys, LLC',
    timestamp: 1427686747854 },
  { ip: '192.168.1.132',
    mac: 'AC:CF:23:3F:9B:33',
    vendor: 'Raspberry Pi Foundation',
    timestamp: 1427686747854 },
  { ip: '192.168.1.140',
    mac: 'b8:e9:37:11:d5:5c',
    vendor: 'Sonos, Inc.',
    timestamp: 1427686747854 },
  { ip: '192.168.1.143',
    mac: '00:19:93:68:65:53',
    vendor: 'Apple',
    timestamp: 1427686747854 },
  { ip: '192.168.1.148',
    mac: 'AC:FC:23:3F:9B:23',
    vendor: 'Hi-flying electronics technology Co.,Ltd (DUP: 2)',
    timestamp: 1427686747854 } ]

The module also provides a cli interface:

$ arpscan
