Socket.io try get wrong url

Question

I'm trying to connect my reveal.js client and master presentations together using socket.io server.

I did all stuff, that Hakim Se describes on his github page, but socket.io still produces an error, while trying to connect to server.

GET http://0.0.7.156:8080/socket.io/1/?t=1393864538446 net::ERR_ADDRESS_UNREACHABLE 

If change 0.0.7.156 to my local machine name, query succeds.

I think I has wrong settings of presentations, but could not understand how to fix them.

Client:

multiplex: {
             secret: null, 
             id: 'a9e10bc1b02efafe',
             url: 'localname:1948' 
    },

Master:

multiplex: {
             secret: '13938623264068002486', 
             id: 'a9e10bc1b02efafe', 
             url: 'localname:1948'
    },

Answer 1

My experience has been that if I use localhost:

url: 'localhost:1948',

Something inside of reveal.js breaks and transforms localhost internally to the "nonsense" address 0.0.7.156 (bonus points to whoever digs into the code and finds the reason for this, I sadly currently do not have the time). If I instead use 127.0.0.1:

url: '127.0.0.1:1948',

Everything works just fine, at least locally for testing.

You will need to change 127.0.0.1 to whatever host name you will use when deploying the slides later on though.

Hope this helps!
