		+	*'''Problem: xserver shuts down and user can't run xserver-related commands after being connected to remote machines for about 20 mins.'''
		+	**'''Solution:''' Apparently in the new Mavericks OS, default ssh settings (as mentioned in ~/.ssh-config file) of ForwardX11Timeout parameter is 20 minutes, meaning that xserver is supposed to time out after 20 minutes in case of untrusted forwarding. ssh -X does untrusted forwarding of x server, so using ssh -X could trigger this problem.
		+	::Two possible solutions:
		+	:#Change ForwardX11Timeout parameter to something like 7 d (7 days). This will cause xserver to time out in 7 days instead of 20 minutes if you use ssh -X - however, this still leaves the problem of the session timing out.
		+	:#Use ssh -Y to connect (which ''does'' do trusted forwarding of xserver). It is not clear at this time if using ssh -Y means xserver will never shutdown.

-NX Distributed Computing Architecture is a suite of technologies and commercial tools, designed to make network computing as easy and widespread as browsing the web. It consists of a thin layer of server software that enables any Unix computer to work as a terminal server. Clients are also available for a wide range of platforms and operating systems. NoMachine has chosen to build the foundations of its NX Distributed Computing Architecture on the well known and widely used X-Window System - the windowing system that's behind the Graphical User Interfaces of Linux and the Unix Operating System.== Installing NX ==
