X11
Contents
Introduction
X11 is a program provided with Macintosh computers that allows one total X Window System implementation for running X11-based applications.
Usage at Duke
The majority of Duke students use X11 to remotely access Linux machines in order to use university owned programs such as Matlab.
How to
In order to connect to a computer remotely, simply start up X11 (which may need to be installed off the OS X install disk), and type: ssh -Y NetId@ComputerName.oit.duke.edu
Where "NetId" is your Duke Net ID, and "ComputerName" represents a linux computer at Duke:
- Carr: carr##.oit.duke.edu (## = 1 to 16)
- Hudson: hudson##.oit.duke.edu (## = 1 to 21)
- Soc-Psych: soc##.oit.duke.edu (## = 1 to 16)
- Teer: teer##.oit.duke.edu (## = 1 to 45)
You should be prompted to answer yes or no to a question if it is the first time you are connecting to a computer, followed by your Net ID password. Then, you should be able to use the X11 terminal just like a Linux terminal. The "-Y" means you are initiating a trusted connection, which is necessary for using graphical applications (gimp, matlab, gnobots2, etc.).
Once you have done this once, all you have to type the next time you startup X11 is "!ssh", which will automatically remember the last address you connected to.
