# WHATPORT(6007)

## NAME

port 6007 — X11 display :7 / second TensorBoard — X11 display :7 by registration; in practice the port a second TensorBoard lands on.

Protocol: TCP  
IANA registry

## DESCRIPTION

By IANA's 6000-6063 x11 block this is display :7. The common real-world sighting is a second TensorBoard instance: 6006 is the default, so a second instance is commonly started with `--port 6007`. Either way you are looking at a machine running graphical or ML workloads, not a general-purpose service. Confirm which by what answers — an X server speaks the X protocol, TensorBoard answers HTTP.

## EXPOSURE

**Do not expose.** Both plausible occupants are unauthenticated: an X server here can be driven by anyone who reaches it, and a TensorBoard here exposes training data to anyone who asks.

## CHECK

```sh
curl -sI http://TARGET:6007/
```
