Hello --
I am trying to set up a secure VNC connection between two systems. The server is running CentOS 5.3 32-bit distribution, and the client is a Windows-based workstation.
I have downloaded and installed the X11VNC packages onto the server. The two packages are the following:
Quote:
x11vnc 0.9.13-8.el5
x11vnc-javaviewers 0.9.13-8.el5
|
I am trying to connect using the SSVNC client. However, while I am able to establish a connection to the server, I am immediately disconnected from it.
According to the instructions given at the x11vnc website, I am running the following command to start the daemon:
The output that I get from the server is the following:

17/12/2013 12:31:33 - use '-nowf' to disable wireframing completely.
17/12/2013 12:31:33 - use '-nowcr' to disable the Copy Rectangle after the
17/12/2013 12:31:33 moved window is released in the new position.

I have checked the sshd_config file. The following line has been uncommented, and the SSH server has been restarted.
When I try to connect via ssh within the ssvnc client, output indicating an initial success, but then a sudden failure appears on-screen. I have included a snapshot of the output with this posting.
What step(s) do I need to take in order to successfully access the desktop of the remote server via a secure connection?
