16 Accessing Remote Desktop using VNC on Dell PowerEdge Servers and MX7000 Modular Infrastructure
4 Connecting Windows with RealVNC and external tunnels
RealVNC is a simple VNC viewer client package. Because RealVNC does not support standards-based
encryption protocols, it may be used in unencrypted mode, or with external TLS or SSH tunnel clients.
Therefore, the general procedures used to start an external tunnel may be used with other clients.
NoteThe RealVNC clients are also available for other OSs such as Linux, Solaris, Mac OS X, Android, and iOS.
For more information about using RealVNC on iOS, see Connecting iOS with RealVNC Viewer, Remoter Pro, and
Remotix.
4.1 Installing RealVNC
To download and install RealVNC Viewer Client:
1. Download the latest suitable (32-bit or 64-bit) VNC viewer client from the RealVNC website
https://www.realvnc.com/download/viewer/.
2. Install client as per instructions shown on the website.
4.2 Connecting by using RealVNC without encryption
To start an unencrypted VNC connection, both Client and Server side encryption settings must be disabled.
To disable encryption on the iDRAC, set the ‘SSL Encryption’ value in iDRAC to ‘Disabled’, and be sure to set
a VNC password. For more information about configuring iDRAC VNC settings by using the GUI, see
Configuring VNC by using the iDRAC GUI. For more information on configuring settings using the RACADM
command line, see Configuring VNC by using RACADM CLI.
To establish a VNC connection by using RealVNC:
1. Start the RealVNC Viewer Client application.
2. In the VNC Server address box, type the iDRAC IP address followed by the VNC port. For example,
198.51.100.215:5901 connects to the iDRAC at IP 198.51.100.215 on port 5901. Press enter or
click the highlighted connection action to connect.
NoteThe default iDRAC VNC port number is 5901.
