Hi Bob question on getting TurboVNC running

[Phil Marsh]

Hi Aaron,
You're right, but I have no need for the encryption ssh provides because my
connection is tunneled through OpenVPN and encryption just adds overhead.
However, SSH also provides x11 forwarding which I don't get from Telnet of
course. So it can make sense to use ssh through the OpenVPN tunnel anyway
and I'll try that. If I use SSH as stand-alone, I'll be setting up a
reverse SSH tunnel.
However, I still don't understand why I can start the Turbo VNC server
(command vncserver) from a Telnet terminal on my other machines (Ubuntu
22.04) but not on the Ubuntu 24.04 machine I've set up for a small company
here in CA at UCI. If I could start the VNC server only on SSH, then I'd
say that's the solution. It doesn't matter whether the Telnet terminal
window is remote or running on the local machine as per the results. I'd be
surprised if SSH helped here?
Thanks, Phil
