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 VNCserver object with the set command. For more information,
see the iDRAC8 RACADM Command Line Interface Reference Guide available at dell.com/support/
manuals.
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>).
Setting Up VNC Viewer Without SSL Encryption
In general, all Remote Frame Buffer (RFB) compliant VNC Viewers connect to the VNC server using the
iDRAC IP address and port number that is configured for the VNC server. If the SSL encryption option is
