EWS now has remote login via NX Client. This software is available for Windows, Linux, Mac(OS X 10.6 or earlier), and Solaris operating systems.
Installation instructions.
These
instructions are for Mac OS X 10.7.
1. Install X11
(if necessary):
If you have not installed the program called
X11, you will need to install X11. Here's how:
First, Insert
the Mac OS X Disc. If the Finder does not open, click finder and
browse to the inserted disc.
Next, Scroll down in the finder
(if necessary) and locate the "Optional Installs" icon.
Finally, double click on the "Optional Installs" and
choose to install X11.
2. From the file manager, go to
Applications -> Utilities -> X11 (It may be called X11.app)
3.
Remotely log-in to linux machine:
Once you have opened X11, you
will see a command prompt (if not, try the menu entry
Applications->Accessories->Terminal). Now you must type this
command:
ssh netid@remlnx.ews.uiuc.edu -Y
(Note only the Y is capitalized. Substitute the users netid for
the
word netid above. You may choose any number less than 43 instead
of
29. The netid is your netid and not "netid"
literally.)
4. Run Matlab:
Once you have logged into a
linux lab computer, type this command at the prompt:
matlab
(matlab is all lowercase letters)
Once
you have followed these steps, you are running matlab. When you
are
finished, you can type "exit".
If matlab doesn't run you may have forgotten the -Y option when
you used the ssh command.
You may also
use the Terminal program but you won't be able to do any graphics
in
Matlab or C.
