# WHATPORT(5961)

## NAME

port 5961 — Unassigned / VNC display :61 — No IANA assignment; VNC display :61 if anything.

Protocol: TCP  
IANA registry

## DESCRIPTION

5961 sits in IANA's Unassigned 5915-5962 range with no service name or assignee. The only convention that touches it is RFB's 5900+display mapping, giving display :61. Everything else here is ad-hoc: an application that grabbed a free port, or a forwarded tunnel endpoint.

## EXPOSURE

**Do not expose.** Treat an unknown listener in this block as a remote-control surface until you have identified it; do not publish it.

## CHECK

```sh
nmap -Pn -sV -p 5961 TARGET
```
