20 Accessing Remote Desktop using VNC on Dell PowerEdge Servers and MX7000 Modular Infrastructure
application is ‘PuTTY. By first configuring ‘PuTTY' to establish a connection with iDRAC SSH Server, the VNC
client will connect to a local socket on the client system which will then securely forward data to the server.
Because the SSH tunneling is not compatible with TLS/SSL encryption, set the ‘SSL Encryption’ value in
iDRAC to Disabled. The iDRAC SSH server and VNC server must remain enabled. 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.

2. Configure PuTTY.
a. Under Connection  SSH Tunnels, add a tunnel. In the Source Port box, specify a local
available port. For example, 5900.
b. In the Destination box, type IP address of the iDRAC wired interface followed by the VNC port.
For example 198.51.100.215:5901.
