# WHATPORT(5950)

## NAME

port 5950 — Unassigned / VNC display :50 — Unassigned by IANA; conventionally VNC display :50.

Protocol: TCP  
IANA registry

## DESCRIPTION

5950 is inside IANA's Unassigned 5915-5962 range. By the RFB convention it is display :50, and hosts that allocate VNC consoles per VM or per user session can reach that far. Because the number is round, it is also a common hand-picked port for a single dedicated VNC server.

## EXPOSURE

**Do not expose.** Assume remote desktop until proven otherwise. RFB offers no transport encryption in its classic security types, so it belongs behind SSH or a VPN.

## CHECK

```sh
nmap -Pn -sV -p 5950 TARGET
```
