If you look way-back in the list archives, you'll see that providing
vnc "web access" out-of-the-box has been bugging me for a while now.

I did a google search and found this jem:


I built packages which give vnc "web access" to K12LTSP, but there are
a couple serious caveats that dimish the usefulness: 

First is that you have to have httpd running and the appropriate holes in
the firewall (tcp ports 80, 5903, 5904). 

Second is that is a bit non-intuitive in that users will first see a "VNC
Authentication" screen. The "Password" field is ignored, they just need
to click on the "OK" button. 

The third issue is the real problem: doing *ANYTHING* to the browser will
kill the session. Clicking on the "Back", "Forward", or "Reload" buttons,
and in some cases resizing the browser, will immediately kill all programs
the user was running and disconnect them. Yuck.

If that does not scare you off, please give these packages a spin ;-)


After installing these on your server, point our web browser to:


where hires = 1024x768 and lowres = 800x600 screens.
