# README

go-natty provides a Go wrapper around the natty NAT-traversal utility.

To install:

For docs:

Demo

There's a demo application available. Right now it only works on OS X. Binaries are available here.

The demo application allows running a client as well as a server peer. The client will connect to the server and obtain its IP address by making a request to ifconfig.me.

The client and server signal with each other using waddell and the client sends UDP packets to the server once NAT-traversal is complete. The client finds the server on waddell using its waddell id.

Example Demo Session

Server

Macintosh% ./natty-demo-osx -mode server                                                            
2014/09/16 18:41:36 Starting server, waddell id is "e6679a41-0003-4f9b-8ae4-671a8a196d13"
2014/09/16 18:41:49 Got five tuple: &{udp 192.168.1.160:55285 192.168.1.160:60530}
2014/09/16 18:41:49 Listening for UDP packets at: 192.168.1.160:55285
2014/09/16 18:41:49 Got UDP message from 192.168.1.160:60530: 'Hello from 192.168.1.160:60530'
2014/09/16 18:41:50 Got UDP message from 192.168.1.160:60530: 'Hello from 192.168.1.160:60530'
2014/09/16 18:41:51 Got UDP message from 192.168.1.160:60530: 'Hello from 192.168.1.160:60530'

Note - you have to specify the waddell id emitted by the server when running the client.

Client

Macintosh% ./natty-demo-osx -mode client -server "e6679a41-0003-4f9b-8ae4-671a8a196d13"
2014/09/16 18:41:46 Starting client, connecting to server e6679a41-0003-4f9b-8ae4-671a8a196d13 ...

go-natty is just a wrapper around natty, which is itself just a wrapper around the WebRTC Native Code Package.
