VCL & Thin Clients

Hello, I am wondering if anyone has successfully booted VCL via PXE boot to an thin client?

Josh,

We are not ready pursue just yet, but thanks for the idea. When we are ready for the pilot program, I will let you know.

Thanks again.

Arbin,

This could be done.  Here is one way I can suggest that can be done without any modification to the current code base.  You would need to write a small app that would interact with the VCL XML RPC API.  The app would need to prompt users for their VCL credentials, which it would need to cache in RAM.  
Then, it would get a list of the environments the user had access to.  The user could then select which environment was desired.  The app would then make the reservation, wait for it to be ready, and then connect to it.  This would be best done under linux where rdesktop could be used which allows for passing the RDP password via the command line.  The biggest problem I see with this method is the API doesn't currently provide a way to get an estimated load time for a given image.  So, the user wouldn't have any way to know if the selected image was preloaded or if it was going to take 20 minutes to load.  
Adding this capability wouldn't take much work, but it just isn't currently there.

I wrote an app that does some of this a few years ago.  It is in python/tk and is more of the "icon on the desktop" concept.  I can try to dig it up if you're really ready to pursue this.

Henry,

Thanks for the info. I just learned today that our priorities have changed
from the ideas I have. The goal now is to reduce the computer labs on
campus. I will keep you updated when I know more.

Arbin,
  This may be a case of choosing the right name to call something.

   Until a couple of years ago I had a 1998 Dell as my desktop PC -
256MB RAM, 1 GHz processor - which got upgraded to XP.  I was able to
"run" many heavy-duty programs on it via RDP client connecting to the
VCL. (Our support people finally took it away from me and gave me a
new desktop because the old one was getting unreliable after 10 years.
:-)

  Was I running a "thin client" at that time?  I would claim I was, as
I was using my screen/keyboard/mouse and the program execution was
taking place remotely in the VCL. I was using the desktop's operating
system/RDP client, but that's what one does with a "thin client" - and
I didn't have to get a license for a thin client OS.

  I did use the desktop, as is, for such things as e-mail and browser
use - and it was able to handle that load with no trouble.

  Might this approach work to fill your needs?
