Technical Details

what runs on :7009

AFS remote cache manager traffic uses the AFS Rx protocol and is assigned to both TCP and UDP, although AFS deployments traditionally use Rx over UDP. Rx provides packet framing, sequencing, acknowledgements, and service-specific operations; the service uses AFS authentication and security-class negotiation where configured. Port 7009 is part of the fixed AFS service range, alongside ports such as 7000 for the file server, 7001 for callbacks, and 7003 for the volume location service. Implementations commonly refer to this service as afs3-rmtsys.

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

security overview

This service should normally be restricted to trusted AFS administration or client networks and should not be exposed to the Internet. AFS authentication can protect requests, but traffic is not encrypted by default in every deployment, and an exposed remote-system interface increases the attack surface of the AFS client or server. Restrict it with firewall rules and use the strongest available Rx security configuration.
