application on the management station. This VNC viewer can connect to OS/Hypervisor on the server and provide access to keyboard, video and mouse of the host server to perform the necessary remediation. Before launching the VNC client, you must enable the VNC server and configure the VNC server settings in iDRAC such as password, VNC port number, SSL encryption, and the time out value. You can configure these settings using iDRAC Web interface or RACADM. NOTE: VNC feature is licensed and is available in the iDRAC Enterprise license. You can choose from many VNC applications or Desktop clients such as the ones from RealVNC or Dell Wyse PocketCloud. Only one VNC client session can be active at a time. If a VNC session is active, you can only launch the Virtual Media using Launch Virtual Console and not the Virtual Console Viewer. If video encryption is disabled, the VNC client starts RFB handshake directly, and a SSL handshake is not required. During VNC client handshake (RFB or SSL), if another VNC session is active or if a Virtual Console session is open, the new VNC client session is rejected. After completion of the initial handshake, VNC server disables Virtual Console and allows only Virtual Media. After termination of the VNC session, VNC server restores the original state of Virtual Console (enabled or disabled). NOTE: • When iDRAC NIC is in shared mode and the host system is power cycled, the network connection is lost for a few seconds. During this time, if you perform any action in the active VNC client, the VNC session may close. You must wait for timeout (value configured for the VNC Server settings in the Services page in iDRAC Web interface) and then re-establish the VNC connection. • If the VNC client window is minimized for more than 60 seconds, the client window closes. You must open a new VNC session. If you maximize the VNC client window within 60 seconds, you can continue to use it. Configuring VNC server using iDRAC web interface To configure the VNC server settings: 1. In the iDRAC Web interface, go to Overview > iDRAC Settings > Network > Services. The Services page is displayed. 2. In the VNC Server section, enable the VNC server, specify the password, port number, and enable or disable SSL encryption. For information about the fields, see the iDRAC Online Help. 3. Click Apply. The VNC server is configured. Configuring VNC server using RACADM To configure the VNC server, use the set command with the objects in VNCserver. For more information, see the iDRAC RACADM Command Line Interface Reference Guide available at dell.com/idracmanuals. Setting up VNC viewer with SSL encryption While configuring the VNC server settings in iDRAC, if the SSL Encryption option was enabled, then the SSL tunnel application must be used along with the VNC Viewer to establish the SSL encrypted connection with iDRAC VNC server. NOTE: Most of the VNC clients do not have built-in SSL encryption support. To configure the SSL tunnel application: 1. Configure SSL tunnel to accept connection on :. For example, 127.0.0.1:5930. 2. Configure SSL tunnel to connect to :. For example, 192.168.0.120:5901. 3. Start the tunnel application. To establish connection with the iDRAC VNC server over the SSL encrypted channel, connect the VNC viewer to the localhost (link local IP address) and the local port number (127.0.0.1:).

Configuring VNC server using iDRAC web interface
To configure the VNC server settings:
1.
In the iDRAC Web interface, go to
Overview
>
iDRAC Settings
>
Network
>
Services
.
The
Services
page is displayed.
2.
In the
VNC Server
section, enable the VNC server, specify the password, port number, and enable or disable SSL encryption.
For information about the fields, see the
iDRAC Online Help
.
3.
Click
Apply
.
The VNC server is configured.
Configuring VNC server using RACADM
To configure the VNC server, use the
set
command with the objects in
VNCserver
.
For more information, see the
iDRAC RACADM Command Line Interface Reference Guide
available at
dell.com/idracmanuals
.
Setting up VNC viewer with SSL encryption
While configuring the VNC server settings in iDRAC, if the
SSL Encryption
option was enabled, then the SSL tunnel application must be
used along with the VNC Viewer to establish the SSL encrypted connection with iDRAC VNC server.
NOTE:
Most of the VNC clients do not have built-in SSL encryption support.
To configure the SSL tunnel application:
1.
Configure SSL tunnel to accept connection on
<localhost>:<localport number>
. For example, 127.0.0.1:5930.
2.
Configure SSL tunnel to connect to
<iDRAC IP address>:<VNC server port Number>
. For example, 192.168.0.120:5901.
3.
Start the tunnel application.
To establish connection with the iDRAC VNC server over the SSL encrypted channel, connect the VNC viewer to the localhost (link
local IP address) and the local port number (127.0.0.1:<local port number>).
