# WHATPORT(5960)

## NAME

port 5960 — Unassigned / VNC display :60 — Unassigned; VNC display :60 by convention, nothing else standard.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA leaves 5960 unassigned as part of the 5915-5962 block. RFB display numbering makes it :60, which is deep into the range and only reached by hosts running many simultaneous VNC sessions. Beyond that there is no registered service and no well-documented squatter.

## EXPOSURE

**Do not expose.** Unregistered plus in the VNC block means you cannot infer safety from the number — keep it internal and check the owning process.

## CHECK

```sh
sudo lsof -nP -iTCP:5960 -sTCP:LISTEN
```
