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 users with Mountain Lion.
For students who
don't have X11 on their Mac ,download XQuartz
http://xquartz.macosforge.org/landing/
After downloading and opening, type
ssh netid@remlnx.ews.uiuc.edu -Y
where netid is
the students actual netid. After authentication, they simply
type "matlab" ( without quotes) at the Linux prompt.
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.

5 - In the "Xterm-like" window enter: 'ssh netid@ews_hostname -Y
NOTE: All EWS hostnames can be found at: http://www.ews.uiuc.edu/labs under "Lab Details" for each lab listed.
6 - After logging into an EWS workstation, run the desired application by entering it's name at the command prompt (i.e., 'matlab &' or a browser like 'seamonkey &' where the & will open these applications in a new window.)
TO CLOSE:
1 - Exit all remotely displayed X programs
2 - Enter 'exit' at each command prompt until CygWin is completely
closed.
