ok... another question... if I have created multiple VNC sessions/displays such that I'm able to connect using a client. If I kill my client, how do I stop someone else from being able to access my desktop if they connect to their vnc client using the same display number.
I ask this because it appears that when i setup the vncserver, I give it a passowrd, which is also required for each client connecting to the linux box. However, the password doesn't change, so anybody could access my desktop... assuming they know the vncserver password. Is there a way to have "multiple" passwords, one each for a different display/user???? thanks... bruce -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Christopher Tesla Sent: Wednesday, December 11, 2002 11:06 AM To: Bruce Douglas; [EMAIL PROTECTED] Subject: RE: logging out of display manager... This is not 100% true all the time, but... If you go to your /tmp/.X11-unix directory there will be a file for each server that is running. For instance: /tmp/.X11-unix ls -a X0 X1 X2 X3 X4 Means you have a VNC server running on ports :0 :1 :2 :3 :4 Again, I have had instances where the VNC server was down, but the X file was still there. But in most cases this will give you the proper info.
