Node.js и Redis Auth

Я не получил документацию redis node.js по использованию redis auth.

в примере:

var redis = require("redis"),
client = redis.createClient();

// This command is magical. Client stashes the password and will issue on every connect.
client.auth("somepass");

В моем коде есть следующее:

var redis = require("redis");
r = redis.createClient(6379,'xxx.xxx.xxx.xxx');
r.auth("yyyyyyyy");

app.get('/', function(req, res){
r.set("foo", 'bar');
res.writeHead(200, {'Content-Type': 'image/gif'});
res.end('Hello');
 });

Вот ошибка, которую я получаю:

    Express server listening on port 8070 in development mode

So, what is the proper way to auth?
