Technical Details

what runs on :7676

iMQ Broker Rendezvous is the broker endpoint used by iMQ/OpenMQ clients for broker discovery and messaging. The registry assigns both TCP and UDP; normal JMS client-to-broker traffic is generally carried over TCP using the broker's proprietary iMQ wire protocol, with persistent connections and framed messaging rather than HTTP. Deployments may provide separate secure JMS or tunneling endpoints, so the exact port and transport behavior depend on broker configuration.

security overview

The service should not normally be exposed directly to the public internet. An exposed broker can permit authentication probing and, if access controls are weak or misconfigured, unauthorized message publication, consumption, or administrative impact; the default iMQ endpoint is not encrypted unless a secure listener is configured.
