Connect mongo db to remote server nodejs

I nave nodejs server and connecting to Mongo DB locally using mongoose as:

mongooseQ.connect("mongodb://localhost:27017/YepiMobile"); 

How can I connect to mongo db that locating on remote server from my machine?

Something like:

mongooseQ.connect("mongodb://remote.server.com:27017/YepiMobile"); 

Does the second connection attempt fail for you, by reading Mongoose's documentation it seems like you have done it correctly:

mongoose.connect('mongodb://username:password@host:port/database?options...');

Maybe you are missing the credentials to the server? See this link for more information: http://mongoosejs.com/docs/connections.html, or see MongoDB's connection documentation: http://docs.mongodb.org/manual/reference/connection-string/.
