examples

A default usage example. For more advanced and possible options please see here or simply look in the included examples/ folder.

scan

The example show shows the types of host ranges supported. In this example the default IANA range of reserved ports is scanned per host in each range (1024).

const nmap = require('libnmap');
const opts = {
  range: [
    'scanme.nmap.org',
    '10.0.2.0/25',
    '192.168.10.80-120',
    'fe80::42:acff:fe11:fd4e/64'
  ]
};

nmap.scan(opts, function(err, report) {
  if (err) throw new Error(err);

  for (let item in report) {
    console.log(JSON.stringify(report[item]));
  }
});

discover

The discover method requires nodejs < v0.11.2 and can be used to aquire information about neighbors per network interface.

const nmap = require('libnmap');

nmap.discover(function(err, report) {
  if (err) throw new Error(err);

  for (let item in report) {
    console.log(JSON.stringify(report[item]));
  }
});
