That doesn't make sense to me. Using a VNC client is considerably easier
than using a web browser (IMHO). Further, the VNC client/server is
designed to handle screen, bandwith, and other vnc specific tasks.

Simple: have him use the ssh instructions below, connect into his
machine and then initiate vnc sessions to the local lan computers from
there. I use this all the time, that way you only have one open
port/path. Added note: on the router only have the ssh and vnc ports
forwarded to the one secure machine, do not allow the IT guy to willy
nilly open up all the machines.

Yes. Assuming that you do have ssh installed on the Ubuntu machines, set
up an specific ssh port.
ssh -L 5910:localhost:5900 <IP of target machine>
Now from your VNC client, I'll use Krdc in this case, but you can use
others - xvnc4viewer is quite nice and also provides scrollbars that
work. xvnc4viewer also provides a decent visible mouse cursor whereas
Krdc only provides a little black box frame for the cursor.
Or from a terminal
All traffic to/from the vnc client will now use the ssh session.
Note that you can also do the same with the Windows machines have RDP -
Krdc can use RDP as well. I've not tried it (RDP), but maybe that is
your solution for connecting to the XP machines - just install ssh and
use the built in Remote Desktop:

For who? You or the teachers? Not being a Smarta** , I'm trying to
understand if the teachers will also be using vnc, or only you and the
