I’m familiar with Node.js so I’m going to use the Node.js hwserver example from zeromq’s website. If you see “Listening on 5555…”, you’re good to go.

// Hello World server
// Binds REP socket to tcp://*:5555
// Expects "Hello" from client, replies with "world"

var zmq = require('zmq');

// socket to talk to clients
var responder = zmq.socket('rep');

responder.on('message', function(request) {
  console.log("Received request: [", request.toString(), "]");

  // do some 'work'
  setTimeout(function() {

    // send reply back to client.
  }, 1000);

responder.bind('tcp://*:5555', function(err) {
  if (err) {
  } else {
    console.log("Listening on 5555…");

process.on('SIGINT', function() {
