# WHATPORT(50002)

## NAME

port 50002 — iiimsf (by convention) — Unregistered; historically associated with the Internet/Intranet Input Method Server Framework.

Protocol: TCP

## DESCRIPTION

There is no IANA assignment for 50002 because it lies in the Dynamic/Private range. Nmap's service database names it iiimsf — the Internet/Intranet Input Method Server Framework, the input-method server used by Solaris-era desktops — which is the only well-attested association the number has. On modern systems an open 50002 is far more likely to be an arbitrary application port in a 50000-based block than an IIIM server, so identify it rather than trusting the label.

## EXPOSURE

**Expose with care.** A desktop input-method server has no business on a network interface at all; anything else here is unidentified until you fingerprint it.

## CHECK

```sh
nmap -Pn -sV -p 50002 TARGET
```
