General
cobra is a real time messaging server. The ws utility can run a cobra server (named snake), and has client to publish and subscribe to a cobra server.
Bring up 3 terminals and run a server, a publisher and a subscriber in each one. As you publish data you should see it being received by the subscriber. You can run redis-cli MONITOR too to see how redis is being used.
Server
You will need to have a redis server running locally. To run the server:
$ cd <ixwebsocket-top-level-folder>/ixsnake/ixsnake
$ ws snake
