Remote login to EWS computers.

For an Apple computer

These instructions are for Mac OS X 10.4 (Tiger). 

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 -> Terminal).  Now you must type this
    command:

   ssh netid@dcllnx29.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".



You may also use the Terminal program but you won't be able to do any graphics in Matlab or C.

For a Windows computer

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.
