```javascript
var scan = require('net-scan');

console.time('ports scan');
scan.port({
	host: 'github.com',
	start: 1,
	end: 1000,
	timeout: 2000,
	queue: 1000
}, function(err, result) {    
	console.timeEnd('ports scan');
	console.log('open ports:', result);
});
```

Output

```shell
ports scan: 2232ms
open ports: [ 22, 80, 443 ]
```

### Ports scan
```javascript
var scan = require('net-scan');

console.time('ports scan');
scan.port({
	host: 'github.com',
	ports: [20, 21, 22, 80, 443, 3306, 27017],
	timeout: 2000
}, function(err, result) {    
	console.timeEnd('ports scan');
	console.log('open ports:', result);
});

```

Output

```shell

scan.port({
		host: 'github.com',
		start: 1,
		end: 1000,
		timeout: 2000,
		queue: 1000
	})
	.on('open', function(port) {
		console.log('found port open', port);
	})
	.on('end', function(port) {
		console.timeEnd('ports scan');
		console.log('scan port over');
	});

```
