Send message from config node to other nodes?

I have multiple config nodes that start a server and listen for events, I would like to forward these events to a different (non config) node that subscribes to the events of a specific config node.

I tried to use node.send and node.emit but none worked, I never receive the event on the other node (node.addEventListener, node.on('input').

Could someone provide guidance please?

Ah! Answering myself.

I have to use RED.nodes.getNode to retrieve the config node, and then attach addListener to it.
