How should I handle multiple publishers on the same port on the same host?

Question

I am using the cluster module and in each of the worker processes I need to publish certain values out to a single server, which subscribes to each worker.

I am using the zmq PUB socket in each worker process, but when each worker socket binds on the same port it causes a conflict and doesn't work. What socket pattern should I use so that I can publish/push/send values from my worker processes and subscribe to them with my server process?

Answer 1

Reverse the pub-sub bind-connect. Sub binds and Pub connects solves the problem.
