I can't SSH to POD's compute servers from off campus or from DMS

Per a directive from the UT Information Security Office (ISO), SSH access using passwords from outside the UT campus network has now been blocked. Please see the POD access discussion for more information.

How to set up password-less access to POD compute servers using public key encryption

...

From your X11-enabled terminal, use ssh -Y to connect to the POD compute server (the -Y enables forwarding of the X11 commands to the X-terminal). Once logged in, type matlab. This will (slowly) open a graphical window to run matlab in.

Here's how to create a script in matlab.

• In the "Command Window" in the middle of the matlab window, type "1+1" and hit return, it should say "2".
• Click the "New Script" button at the upper left (or the "New" Button, then select "Script" if you don't see "New Script").
  
  • This will open an editing window for a script. 
    
• Type "1+1" in the window, then click "Save" from the upper menu. 
  
  • Name it anything with a ".m" extension (such as untitled.m, the default). 
    
• You can then use then "Open" menu, or the "Current Folder" pain, to open that file in the future.
• Once open in the Editor, you can use the "Run" command from the Editor menu to run it.
• Exit matlab (using either the "exit" or "quit" command)
  

To open matlab without the graphical interface, type the not-so-short or intuitive command: matlab -nodisplay -nosplash. This should give an interactive command prompt. To exit, type quit or exit. Other sometimes-useful options for the non-GUI matlab include -nojvm (might speed things up a bit) and -wait (wait until your jobs finish before exiting).

To run the "script" we created above (called untitled.m in your home directory) and exit, you can do something like:

matlab -nodisplay -nosplash -r "run('~/untitled.m');quit"

To add some error checking, you can use:

matlab -nodisplay -nosplash -r "try, run('~/untitled.m'), catch, exit, end, exit"

Another simple example script could be created and executed from the command line as shown below. (It should tell you the answer is "7.3529".)

echo "5^3/(2^4+1)" > ~/untitled2.m
matlab -nodisplay -nosplash -nojvm -r "run('~/untitled2.m');quit"
