You can use the X window system to ‘remote’ into another machine. In OS X it launches X11, as this is the X window client for Mac. What is actually happening is the remote system is sending system information to your local machine and allowing that to render the desktop and graphical views. This is opposed to the way VNC or Apple Remote Desktop works, by taking that already rendered image and compressing it down to sent it over the pipe. The ‘X -query’ tends to have better performance on remote systems because you aren’t sending full screen graphics, only remote system calls.
To do this, use the following command:
X -query I.P.Add.ress
