find-port

find an unused port in your localhost

	var findPort = require('find-port')

	// scan a range
	findPort('127.0.0.1', 8000, 8003, function(ports) {
		console.log(ports)
	})

	// scan explicitly
	findPort('127.0.0.1', [8000, 8011], function(ports) {
		console.log(ports)
	})

• Since version 2.0.0 a local interface must be specified
• This module is not designed to scan remote ports only local ones.
