How to get the user IP address in Meteor server?

Question

I would like to get the user IP address in my meteor application, on the server side, so that I can log the IP address with a bunch of things (for example: non-registered us

Here's a way that has worked for me to get a client's IP address from anywhere on the server, without using additional packages. Working in Meteor 0.7 and should work in earlier versions as well.

On the client, get the socket URL (unique) and send it to the server. You can view the socket URL in the web console (under Network in Chrome and Safari).

socket_url = Meteor.default_connection._stream.socket._transport.url
Meteor.call('clientIP', socket_url)

Then, on the server, use the client's socket URL to find their IP in Meteor.server.sessions.

sr = socket_url.split('/')
socket_path = "/"+sr[sr.length-4]+"/"+sr[sr.length-3]+"/"+sr[sr.length-2]+"/"+sr[sr.length-1]
_.each(_.values(Meteor.server.sessions), (session) ->
    if session.socket.url == socket_path
        user_ip = session.socket.remoteAddress
)

user_ip now contains the connected client's IP address.
