	www.x.org gives that answer.

	"The X.Org project provides an open source implementation of the X Window System."

	This is a configuration setting, that depends on who starts the X Server is required
	to setup and pass in authentication credentials.

	In general all modern day Desktop Managers like XDM, GDM, KDM and others do secure setup
	out of the box, but this could be overridden by logged in users, or local setups.

> 3.       How is port 6000 and 6001 associated with x11?

	The TCP ports 6000 and 6001 associate with the first DISPLAY ( named :0 ) and the second
	( named :1 ) which are used commonly in X Server setups.

	These ports are commonly served by the X Server.

Ciao, Marcus
