motely.) From off-campus, you can ssh to math.hws.edu, but not
all the applications that you are used to are installed on that
computer.
An ssh client logs you into a command line interface. However,
you will still be able to use GUI applications, such as gedit,
eclipse, and firefox. These applications are actually running on
the remote computer. Your computer is just being used as a display.
The "-X" option in the ssh command is what allows you touse GUI
applications. (It must be an upper-case X, and there must be spaces
before and after -X. If you don't want to use any GUI
applications,' you can leave out the -X.) For the new Mac OS 10.8,
X might not be pre-installed on your computer. However, it can
still be downloaded and installed; see
http://xquartz.macosforge.org/landing/.
It is possible to use ssh under Windows. Since ssh is not a
standard part ofWindows, you must install an ssh program to do so.
One such program is "putty,"which you can obtain from
http://www.chiark.greenend.org.uk/~sgtatham/putty/. Unfortunately,
you will not be able to use GUI applications through ssh under
Windows.
