# WHATPORT(5922)

## NAME

port 5922 — Unassigned / VNC display :22 — Unassigned by IANA; in the wild it is VNC display :22.

Protocol: TCP  
IANA registry

## DESCRIPTION

5922 falls inside IANA's Unassigned 5915-5962 block, so nothing has a claim on it. The realistic listener is an RFB server on display :22, since VNC maps display :N onto 5900+N. The number is memorable enough that people also pick it by hand for a VNC session, the way 2222 gets picked for SSH.

## EXPOSURE

**Do not expose.** Do not expose a VNC display directly. Tunnel it (ssh -L 5922:localhost:5922 TARGET) so authentication and confidentiality come from SSH rather than from RFB.

## CHECK

```sh
nc -w 3 TARGET 5922 | head -c 12; echo
```
