To connect to your lab account from anywhere on the net do this:

From a Mac or Linux system:

   ssh -X -oport=2200 mat275(a)@mathexx.la.asu.edu
This is for graphics with Matlab.

   ssh -oport=2200 mat275(a)@mathexx.la.asu.edu
This is without graphics.
At the prompt type matlab or matlab& to retain the prompt.
To transfer files use sftp -oport=2200 mat275(a)@mathexx.la.asu.edu
and then put file get file as desired.

From a Windows system:

Download SSH for Windows from myapps.asu.edu. Use mathexx.la.asu.edu
as host, mat275(a) as userid, set the port to 2200 from 22 and use
password as authentication. When prompted type your password. This is
without graphics. Once you are in, type matlab and use it without graphics.
You can also use SSH to transfer files back and forth.

For Windows with graphics you need to enable X11-forwarding. At this point
I recommend the following free package:
    http://sourceforge.net/projects/xming/
Use SSH to make the connection and Xming as X11 client. You download Xming
and acticate it by clicking on its icon. In SSH you have to enable X11-forwarding by choosing X11-tunneling in 'settings'.
Instead of SSH you can also use putty (activate X11-forwarding in it):
    http://www.chiark.greenend.org.uk/~sgtatham/putty/
For file transfer you would then use their PSFTP. Don't forget port 2200!

IMPORTANT:
If you are in the lab during open hours and cannot get to your computer,
then go to a free computer and login as student. Open a terminal (click on
icon) and in the window use the ssh command above. If you are remotely
logged in to your account and want to fetch a file from a URL you know
then use the command:    wget URL  for example
                         wget http://plato.asu.edu/MAT275/manualfiles/euler.m
Note, you cannot use a browser on the other computer you are at because
it downloads the file to this computer and not yours. Of course, you can move
the file from the local computer using sftp. A lot can b done!

Hope to see you all a bit more computer-literate by the end of the semester!
