# WHATPORT(5679)

## NAME

port 5679 — dccm (Direct Cable Connect Manager) — A dead registration — Direct Cable Connect Manager — with nothing in common use behind it.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 5679 as dccm, "Direct Cable Connect Manager", assigned to an individual and tied to the direct-cable networking era of consumer Windows. No widely deployed software listens here now. If 5679 is open on a machine you own, it belongs to some local application that picked the number, so identify it by process rather than by the registry.

## EXPOSURE

**Expose with care.** Nothing well-known claims this port, so an open 5679 is an unidentified service. Find the owning process before deciding whether it may be reachable.

## CHECK

```sh
sudo lsof -nP -iTCP:5679 -sTCP:LISTEN
```
