# WHATPORT(6059)

## NAME

port 6059 — X11 display :59 — X11 display :59, near the top of IANA's 6000-6063 x11 block.

Protocol: TCP  
IANA registry

## DESCRIPTION

This is display :59 under the x11 range registration, four short of where the range ends at 6063. Nothing else is registered here, and there is no well-known product that claims it. In practice a listener means a busy X11 host — a terminal server, or a pool of Xvfb/VNC displays — with TCP transport enabled rather than the usual Unix-socket-only configuration.

## EXPOSURE

**Do not expose.** Same as any X display over TCP: full read and write access to a live session for whoever gets past (or around) the xauth cookie.

## CHECK

```sh
sudo lsof -nP -iTCP:6059 -sTCP:LISTEN
```
