Script Description

---

The x11-access.nse script checks if you're allowed to connect to the X server.

If the X server is listening on TCP port 6000+n (where n is the display number), it is possible to check if you're able to get connected to the remote display by sending a X11 initial connection request.

In reply, the success byte (0x00 or 0x01) will determine if you are in the xhost + list. In this case, script will display the message: X server access is granted.
