Technical Details

what runs on :5785

HPE 3PAR Remote Copy uses this port for communication between storage arrays participating in replication. IANA lists both TCP and UDP, though array-to-array Remote Copy is generally encountered over TCP. It is specialized storage traffic rather than a general client protocol; detailed handshake and framing behavior are vendor-specific.

security overview

Do not expose this service to the public internet: restrict it to the intended array peers on a dedicated or otherwise tightly controlled network. Remote Copy traffic concerns storage systems and replicated data, so unexpected reachability warrants investigation; the registry assignment alone does not establish that a listener is present or identify its authentication and encryption settings.
