TCP 6789
Synopsis
- Ceph Monitor (ceph-mon) uses TCP port 6789 for its legacy “Messenger v1” protocol.
- This is common in real deployments such as Red Hat Ceph Storage, SUSE Enterprise Storage, and OpenStack environments backed by Ceph; newer Ceph versions also use port 3300 for “Messenger v2” while often keeping 6789 enabled for backward compatibility.
