Not connecting

I tried this

```
var ftpd = require("ftp-server")
ftpd.fsOptions.root = '/'
ftpd.listen(21)
```

The server starts up but I can't connect to it.
I know its up because when I throw a console.log in the `server.on('connection', function (socket) {`... it works.

When I try to connect it doesn't work
