# WHATPORT(4998)

## NAME

port 4998 — Unassigned — Unassigned at IANA — no standard service owns 4998.

Protocol: TCP  
IANA registry

## DESCRIPTION

4998 has no entry in the IANA service name and port number registry, while its neighbours 4999 (HFSQL manager) and 5000 (commplex-main) do. Nmap's services file lists it as "maybe-veritas" with a very low hit frequency, a guess carried from old scan data rather than a confirmed protocol. Anything listening here is application-specific, so identify it by its banner rather than by the number.

## EXPOSURE

**Expose with care.** An unregistered port tells you nothing about what is behind it. Find out what process owns the socket before deciding whether it belongs on a public interface.

## CHECK

```sh
sudo lsof -nP -iTCP:4998 -sTCP:LISTEN
```
