rendezvous-socket

Rendezvous::Socket

Using the help of a known publically routable rendezvous-server endpoint establish a peer to peer connection between clients which may be behind NAT firewalls. In the event that NAT traversal techniques are not successful fallback to relaying the connection through the rendezvous server. All connections are SSL encrypted. Sessions are managed by the server.

Installation

Add this line to your application's Gemfile:

gem 'rendezvous-socket'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rendezvous-socket

Usage

1. Deploy the server
2. On 2 peer machines that wish to establish a direct connection with each other run the client.

RENDEZVOUS_URL=https://rendezvous-server.herokuapp.com rendezvous-client

You will know it worked when you see the hostname of each peer in the output of it's peer.

TODO

• Server managed sessions
• SSL
• Clean interface (as similar to socket interface as possible)
• Fallback to relay mode
• Link local connection attempt
• Figure out why linux does not even attempt to send packets somtimes. Connect vs Accept first?
