Simply exit each of your Unix applications, for example by using the Exit menu item in Unix or by typing exit in the terminal windows. If you happen to close all of your terminal windows to your Unix machine, you can create a new terminal connection without closing and reopening the X windows application. It's possible, of course, to switch between running Unix programs and using applications directly on your client machine. You can use the SSH command in that window to make an additional connection to one of the Unix machines. You should note that if you use the Applications menu of the X11 application and select Terminal, you'll get a new window in which you can issue commands to the Mac. The ampersand tells the terminal window that you would like to run the program "in the background," meaning that you can immediately issue more commands in the terminal window. The emacs command runs the editor, matlab is a data analysis program, xeyes is a cool little graphical application, and the gnome-terminal command opens an extra terminal window. Here are some examples: emacs Whatever.java & matlab & xeyes & gnome-terminal &
#X11 or xquartz software#
In the new white window, you can begin to issue Unix commands that will open a graphical version of the software on your local computer. Once you have your first terminal window to the Unix server.Ĭreate another terminal window that’s already logged in to the Unix server with the command
See the Unix general information page for more information on what you can do in the window.
That will give you an initial terminal session on romulus. You will be asked for your Amherst College password, but note that you won’t see any Then press the key Return or Enter to submit it for processing. Type the following in the terminal window that you got when you started X11: ssh -Y -oHostKeyAlgorithms=+ssh-rsa -oPubkeyAcceptedAlgorithms=+ssh-rsa you, we mean your Amherst username. Remus is accessed in precisely the same way. In the examples that follow, we'll suppose that you are trying to connect to romulus. Let us know if you have problems getting X11 or XQuartz to work.
#X11 or xquartz install#
If you can't find it on your system, you should install XQuartz. X11 is preinstalled in older versions of OS X. When you use a connection of this kind, you have one or more windows to the other machine, which appear as part of your Mac desktop. One way to access the Unix systems is with X windows. Most of the ideas mentioned here can be applied equally well to our departmental systems. Students in advanced classes may use systems managed by our own department.
#X11 or xquartz full#
In general you can refer to the machines by their short names when you are on-campus and by their full names, including the suffix, when you are off-campus.
The two machines are interchangable, so you can work on whichever one you want. Students in introductory computer science classes work on two Unix systems, and.
