# WHATPORT(3370)

## NAME

port 3370 — satvid-datalnk (Satellite Video Data Link) — The middle of IANA's 3367-3371 satellite-video reservation — a registration with no public protocol behind it.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

3370 falls inside the satvid-datalnk range IANA assigned to Scott Engel for a "Satellite Video Data Link". There is no RFC, no published wire format, and no widely deployed implementation. In practice the port is free real estate: application servers, test harnesses, and ad-hoc proxies land on it because nothing else claims it. Treat a listener here as unidentified until you have matched it to a process.

## EXPOSURE

**Expose with care.** Any exposure decision depends entirely on what is actually bound — identify the process first, because the registration tells you nothing about it.

## CHECK

```sh
ss -lntp 'sport = :3370'
```
