Concept Example

This example implements a simple peer-to-peer chat which utilizes the basic concept of UDP hole punching exactly as described in the concept document.

See the visualization here.

Usage

Client

The well known rendezvous server can be optionally specified with the first command line argument.

client [rendezvous] 

or

go run ./client [rendezvous] 

with rendezvous defined here. It defaults to rendezvous = localhost:5001.

Server

The listening address may be optionally set as first command line argument.

server [laddr] 

or

go run ./server [laddr] 

where laddr := <rendezvous>. It defaults to laddr = :5001.

When the server is started via ./server/docker-compose.yml (or the Dockerfile) and any other laddr than the default is desired, the Dockerfile as well as the docker-compose have to be adjusted accordingly (entry point, port mapping).
