# WHATPORT(7625)

## NAME

port 7625 — Unassigned — A single unassigned port wedged between INDI on 7624 and SIMCO on 7626.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA assigns 7624 to indi (Instrument Neutral Distributed Interface, the astronomy device-control protocol) and 7626 to simco, but leaves 7625 unassigned. Nmap gives it no service name and an open-port frequency near 0.04%. If you find 7625 open on an observatory or astrophotography box, the interesting neighbour is 7624, not this port; on anything else it is a locally chosen number.

## EXPOSURE

**Expose with care.** Unregistered and unidentified. Find the listening process first; adjacent INDI on 7624 is itself an unauthenticated device-control protocol that should stay on the LAN.

## CHECK

```sh
sudo lsof -nP -iTCP:7625 -sTCP:LISTEN
```
