Using VNC Client to Manage Remote Server
You can use a standard open VNC client to manage the remote server using both desktop and mobile devices such as
Dell Wyse PocketCloud. When servers in data centers stop functioning, the iDRAC or the operating system sends an
alert to the console on the management station. The console sends an email or SMS to a mobile device with required
information and launches VNC viewer 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 iDRAC7 Web interface or RACADM.
NOTE: VNC feature is licensed and is available in the iDRAC7 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 not the Virtual Console.
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).
Configuring VNC Server Using iDRAC Web Interface
To configure the VNC server settings:
1.
In the iDRAC7 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
iDRAC7 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
RACADM Command Line Reference Guide for iDRAC and CMC
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.
