# WHATPORT(10004)

## NAME

port 10004 — emcrmirccd — Registered to the EMC Replication Manager client agent; the UDP side is Reserved.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA assigns 10004/tcp to emcrmirccd, the EMC Replication Manager Client — the agent installed on application hosts so the Replication Manager server can coordinate array-based snapshots and clones. The corresponding UDP entry is Reserved rather than assigned. It is a storage-management agent, so it belongs to a managed data-center estate; Nmap sees the port open on about 0.03% of scanned hosts.

## EXPOSURE

**Do not expose.** A storage-replication control agent can quiesce applications and manipulate array copies. It should only be reachable from its management server on an internal network.

## CHECK

```sh
nc -vz TARGET 10004
```
