Technical Details

what runs on :8009

The registered service is the NVMe over Fabrics Discovery Service on TCP port 8009. A host establishes an NVMe/TCP connection to a discovery controller and requests its Discovery Log Page, which lists available subsystems and connection information; the host can then connect to an I/O subsystem separately. This is an NVMe protocol service, not an HTTP endpoint. Port 8009 is the conventional discovery port, while NVMe/TCP I/O commonly uses TCP 4420; deployments can configure different ports.

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

security overview

Discovery can reveal storage subsystem names, transport addresses, and other topology information, making an exposed service useful for reconnaissance. It does not by itself grant access to namespace data, but hosts may be able to connect to the advertised storage endpoints, so restrict discovery and I/O services to trusted networks and configure authentication where supported. Traffic is not encrypted by default; do not expose it to the public internet.

Record

iana registry entry

port: :8009
service: NVMe over Fabrics Discovery Service
transport: TCP
encryption: cleartext
assignment: iana registered
risk: 4/10caution
category: Network Services System
usage: An NVMe-oF discovery controller listens here so hosts can retrieve information about storage subsystems and their connection addresses. Engineers typically encounter it in NVMe/TCP storage environments; the storage I/O connections commonly use TCP port 4420 instead.
