Shadow or monitor a thin client
TightVNC Server is installed locally on the thin client. It allows administrators to shadow/operate/monitor a thin client from a remote machine on which TightVNC Viewer is installed (TightVNC Viewer is available from the TightVNC website and must be installed on the remote/shadowing machine before use; it is also included as a component of Cisco VXC Manager software).
You may also be able to shadow thin clients using other third-party VNC viewers.
TightVNC (Server and Viewer) allows a remote administrator to configure or reset a thin client from a remote location rather than making a personal appearance at the thin client site (VNC is intended primarily for support and troubleshooting purposes). TightVNC Server starts automatically as a service at thin client startup if the administrator has configured it using the INI file.
The administrator must configure the client using INI parameters to enable VNC access. You must use the same INI file configuration to enable VNC whether you are using Cisco VXC manager or TightVNC Viewer to access the thin client. See INI configuration example for enabling VNC for an example configuration.
Before an administrator on a remote machine (on which TightVNC Viewer is installed) can access a thin client (with TightVNC Server) the administrator must know the following:
The IP address (or valid DNS name) of the thin client that is to be shadowed (see Viewing system information).
The security password of the thin client that is to be shadowed.
This appendix includes the following:
Shadow a thin client from a remote machine
To shadow a thin client from a remote machine:
Open the New Tight VNC Connection dialog box (for example, from Microsoft Windows, click
Figure 1. New TightVNC Connection Dialog Box
Enter the IP address or valid DNS name of the thin client that is to be shadowed (you can also set other options using the command buttons).
Click OK to open the VNC Authentication dialog box.
Figure 2. Standard VNC Authentication Dialog Box
Enter the password of the thin client that is to be shadowed (this is the Security Password of the thin client that is to be shadowed), and click OK. The thin client that is to be shadowed is displayed for the administrator in a separate window on the remote machine. Use the mouse and keyboard on the remote machine to operate the thin client just as you would if you were operating it locally.
INI configuration example for enabling VNC
You can use the following example INI file configuration to enable VNC on the thin client:
This example enables VNC connections on the client, with no password authentication required to access the client, and without prompting the user to accept VNC shadowing before the shadowing starts.
For details about using INI files, see INI Files Reference Guide for Cisco Virtualization Experience Client 6215 .
VNC Server Preferences dialog box
Use the VNC Server Preferences dialog box (from the Desktop, click
) to manually set Sharing, Security, and Notification VNC Server preferences for use with remote administration. For example, you can set the Security password (the password an administrator must use when shadowing the thin client) in this dialog box.
