# WHATPORT(3030)

## NAME

port 3030 — arepa-cas (in practice: ad-hoc dev server) — Registered to Arepa Cas; in practice a spare development-server port next door to 3000.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 3030 as `arepa-cas`, Arepa Cas, registered by Stuart Schaefer, with no RFC, no public specification and no implementation anyone meets today. What actually listens on 3030 is a local development server — a Node, Rails or similar app started on 3030 because 3000 was already taken — so the port carries no protocol guarantee at all. Scanners will still label it `arepa-cas` from /etc/services. Identify whatever is there by its banner or an HTTP request, not by the registered name.

## EXPOSURE

**Expose with care.** Nothing standard runs here, so an open 3030 is an unidentified service — usually an unhardened dev server that was never meant to leave localhost.

## CHECK

```sh
curl -sS -D - -o /dev/null http://TARGET:3030/
```
