There are two ways to install the VNC server on Windows clients:
Basic VNC installation
Secured VNC installation
In the basic set-up, communication is not encrypted and password authentication is used.
You need to install Tightvnc on the client boxes. This utility is available with your web browser on the http://server_address, "Windows Utilities," "Executable for setting up tightvnc".
During the installation you need to validate the "TighVNC Server" option. Both configuration options "Register TightVNC Server as a system service" and "Start or restart TightVNC service" have also to be selected.
At the end of the setup you have to enter a password. It will be used to connect the remote client from the server web page. The default password on our installations is "linbox". Please change the password to a personal password.
To change the password you need to launch the VNC settings screen which is available in Start menu -> TightVNC -> Administration -> Show Default Settings. Two password entries (password and confirmation) are displayed on the top-left corner of the window. Enter the new pass in the both entries and then apply the changes (button on the bottom of the window).
Now TightVNC is installed and configured, the client is ready to be used.

TightVNC server can also be deployed using Post-Installation scripts ("vnc1" script), or using the LSC module (vnc1.bat). |
With the secure installation, communications between the LRS and the client are encrypted using a SSH tunnel, and public key authentication is used. However, communications between the Web browser and the LRS are not encrypted because plain VNC protocol is used.
First, you have to install an SSH server on the Windows client. Please refer to the LSC module documentation.
Then, install the secured SSH server. Installing the SSH server can be done using a Post-Installation script (the 'lscsshvnc' installs both SSH and VNC) or using the LSC module (vnc-ssh.bat script). The installed binary is called 'tightvncssh.exe'.
You should also check that the "Set up an SSH tunnel before" option is activated in the Webmin VNC module configuration page, to make sure that an SSH tunnel will be set-up before taking control of the client.
The remote control is available from the "Ctrl." column of the LRS screen. You just have to click in one of the clients' icons to go to the login screen:
Enter the VNC client's password to connect the remote box and control it. The client's screen will be displayed in your web browser.
If the remote host is not available, please check that :
The host is up and connected to the network.
The host is running a started VNC server.
The host has the same name under MS Windows (or in the DNS) and in the LRS interface.
The host's selected video mode has at least 256 colors.
If the VNC/SSH mode is activated and if the LRS name has been changed, check that the name has been also changed in /etc/hosts.
