NowJS is never ready - Socket.io might not work
===

I installed NowJS this morning and wanted to try the examples provided by [NowJS website][1].
After having some problem with the "requiring" of nowjs (solved [here][2]), the server started well.
But I face a new problem : now.ready() is never called, as if the websocket connexion never happend...
It began with an error in javascript console : Uncaught exception: TypeError: 'now.distributeMessage' is not a function
That means, I think, that the client never connect to the server and when I debug now with console.log(), I don't see any socketio attribute in now.core, what doesn't seems to be normal.

So what happend ? How do you think I can solve that problem ? Is it caused by a bad installation ? Or is it because I have to open some port in my router ?

I work under Ubuntu 12.04, if it's usefull for answers.

Thank you for the incoming answers ! =)
