# WHATPORT(2038)

## NAME

port 2038 — objectmanager (registration only) — Registered as objectmanager with no documentation and no known implementation.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

The IANA registry lists objectmanager on TCP and UDP 2038 with an empty description, assignee and reference. Nothing well-known listens here, and Nmap's data shows it open on about 0.02% of scanned hosts. The generic name attracts guesses about CIM/WBEM object managers, but those services register elsewhere (5988/5989); the 2038 entry has no published protocol behind it.

## EXPOSURE

**Expose with care.** Treat a listener here as unidentified software. Whatever is answering is not the registry name, so judge exposure by the actual process.

## CHECK

```sh
sudo lsof -nP -iTCP:2038 -sTCP:LISTEN
```
