# WHATPORT(5030)

## NAME

port 5030 — reserved — Marked Reserved at IANA — an old "surfpass" registration that was given back.

Protocol: TCP  
IANA registry

## DESCRIPTION

The current IANA registry shows 5030 as Reserved with no service name, meaning an earlier assignment was withdrawn rather than replaced. Nmap's services file still carries the historical name surfpass, which is why scanners sometimes print it. There is no live protocol to expect here, so anything listening is a private application choice.

## EXPOSURE

**Expose with care.** Nothing standard should be on 5030. Identify the owning process before allowing it through a firewall.

## CHECK

```sh
sudo lsof -nP -iTCP:5030 -sTCP:LISTEN
```
