36.5 Establishing SSH Tunneling

The VNC protocol and data are unencrypted between the management console and the managed
device. If you perform Remote Management operations over an insecure network like Internet, you
should tunnel the VNC protocol using SSH for secure communication.
1 Establish SSH tunneling to use VNC between management console and managed device.
2 Launch the Remote Control session from Device Tasks at the top left of the ZENworks Control
Center on the Devices page.
3 Specify the IP address and port of the configured SSH tunnel.
4 Select the desired operation from drop-down list.
5 Click OK.
