# WHATPORT(14441)

## NAME

port 14441 — Unassigned — Unassigned; IANA registers nothing between 14414 and 14500, and 14441 sits in that hole.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA leaves 14441 unassigned — the surrounding registrations are `ca-web-update` (14414, CA eTrust Web Update Service) and `xpra` (14500, the xpra network protocol). Nmap's service table lists it as `unknown`. No published product default, malware family, or scanner signature is tied to it. Note that 14441 and 14442 are frequently seen together, which usually means one application claimed a small consecutive block for a control and a data channel rather than that either number is registered.

## EXPOSURE

**Expose with care.** Unknown listener. If it appears alongside 14442, identify both — a paired control/data channel is often an internal-only protocol.

## CHECK

```sh
nmap -Pn -sV -p 14441-14442 TARGET
```
