VNC Sharing :0 (When connected, physical screen open to anyone)

guardian653 · 07-24-2004, 03:23 AM

I installed RealVNC recently and I'm using the "vnc" X module. It does what its intented for (sharing :0, my local X window) but I find that if I'm using it remotely anyone near my computer (server-side) can simply turn on the monitor and see what I'm doing remotely. In Windows XP (RDP) if you login remotely using their client it "locks" the computer server-side so you can't see what the remote user is doing.

Is there anyway to emulate this with RealVNC?

You can try using x11VNC. They have some kind of experimental support for this: http://www.karlrunge.com/x11vnc/#FAQ-23 . Basically, they send the monitor a "DPMS off" signal. If someone happens to wake it up, it immediately launches a screen lock utility.

Also, don't know if this applies to you, but the guy from http://www.linuxquestions.org/questions/history/206664 is doing something similar. However, when he starts VNC remotely, it starts a new X session. So, the X session already running server-side is never affected, and people will not be able to see what you are doing...

I didn't understand very well your doubt but if you don't want that the others see what you are doing just block the IP of that computer and allow just the computer that you want!

As the zakaluka mentioned above, the provided link explained what I wanted clearly

Quote:

Q-23: I use a screen-lock when I leave my workstation (e.g. xscreensaver or xlock). When I remotely access my workstation desktop via x11vnc I can unlock the desktop fine, but I am worried people will see my activities on the physical monitor. What can I do to prevent this, or at least make it more difficult?

The second suggestion was to just to make VNC use its own X server, so a new question. Is it possible to run an application on one X screen and then move it to different X screen; and if so, how?
