Technical Details

what runs on :1186

The default NDB Cluster management-server port is TCP 1186. ndb_mgmd accepts connections from cluster nodes and management clients using a proprietary NDB management protocol for cluster configuration, node status, startup, and administrative commands; standard deployments use TCP even though the IANA assignment lists both TCP and UDP.

security overview

This is a cluster-management interface rather than a public application endpoint and should be restricted to trusted cluster hosts and administration networks. Traditional deployments rely heavily on network isolation and do not provide the protections expected from an internet-facing, authenticated and encrypted management service; exposure can disclose cluster topology or enable administrative operations depending on configuration and version.
