7 Accessing Remote Desktop using VNC on Dell PowerEdge Servers and MX7000 Modular Infrastructure
2 Configuring the iDRAC VNC server
The iDRAC VNC server is disabled by default and must be configured to be used. There are a number of
general- and security-related settings.
The iDRAC VNC settings may be configured by using the web GUI or RACADM Command Line Interface
(CLI) as described in this document. Settings may also be changed by using programmatic interfaces such as
WS-Man. For more information about WS-Man, see the Dell Tech Center resources provided in Technical
support and resources.
2.2 General VNC server settings
The VNC server attributes are:
Attribute
Description
Enable VNC Server
Enable the server to use VNC. By default, the VNC server is disabled.
Max Sessions
The maximum number of sessions to allow. On a 14G system, up to two
sessions are supported, on a 13G or 12G server only one session is supported.
Additional sessions consume more resources.
Active Sessions
This reflects the number of sessions in use, the maximum number of sessions
cannot be exceeded. If this appears to be in error, the VNC server may need to
be reset, see Troubleshooting issues when accessing remote desktop using
VNC.
Timeout
The session timeout ranges from 60–10800 seconds (3 hours). The default is
300 seconds (5 min).
Port Number
The TCP Port number to use. By default, this is 5901.
Note—Many VNC clients default to port 5900. However, by default,
iDRAC uses port 5900 for the web Virtual Console. If using the iDRAC
default properties, be sure to set the port number on the client to 5901.
