# WHATPORT(3367)

## NAME

port 3367 — satvid-datalnk (Satellite Video Data Link) — First port of the 3367-3371 Satellite Video Data Link block; no public protocol behind it.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA assigns 3367 through 3371 as one block named `satvid-datalnk`, "Satellite Video Data Link", registered by Scott Engel. It is a vendor registration with no RFC, no published wire format and no implementation in general circulation, so the registry line is the entire public record. Many systems do not even carry the block in /etc/services, so scanners may report 3367 as unknown. Anything actually listening here needs identifying on its own terms.

## EXPOSURE

**Expose with care.** Nothing standard runs on 3367, so an open port is an unidentified service — fingerprint it before deciding.

## CHECK

```sh
nc -vz TARGET 3367
```
