Opengear Application Note: SDTConnector + Dell Page 8 of 14

Also ensure there are no conflicting services running on TCP port 623.

When I select Activate Console Redirection from the SOL Proxy menu, the connection times out.

Ensure the Opengear SSH gateway is configured to allow SOL for the gateway user you are using with SDTConnector (e.g.

delladmin), as per the section Configuring the Opengear SSH gateway to permit SOL.

You can confirm this is working by checking the Opengear system logs, search for output by udpgw and ensure UDP port 623 is

being allowed for your user.

If this is working, the problem is with your BMC or network configuration. To troubleshoot this, install the SOL Proxy on a

system local to the BMC (e.g. on the management LAN itself) and ensure you can connect directly to the BMC by clicking Start -

> Run -> and type telnet localhost 623, then select 3, then type the IP address of the BMC, in the example above we used

192.168.0.200 (do not type 127.0.0.1 as you would when using SDTConnector).

When I click the SOL button SDTConnector displays the error, Couldn't redirect port ... ?

Ensure UDP port 623 is not in use by another running program.

In Linux, ensure you are running SDTConnector with super user privileges, as port 623 is a privileged port and you will be

unable to bind it otherwise.

4. Connecting to DRAC services

PowerEdge servers may be configured with an optional remote access card (Dell RAC or DRAC) that contains a systems

service processor. As detailed earlier it provides out of band and remote access and control of the PowerEdge server,

independent of the operating system.

So the DRAC is similar to the onboard BMC, however the add-on remote access cards are more full featured and powerful.

Advantages over the BMC include providing remote graphical access to the PowerEdge using a virtual KVM, and remote server

monitoring via a web page. The DRAC also has its own Ethernet network port, while the BMC shares a port with the system.

The instructions below are for interfacing to the DRAC version 4.

Configuring the DRAC

The default IP address of the DRAC Ethernet port is 192.168.0.120 with a default gateway of 192.168.0.1. These are the

addresses we will use in this example, as they are compatible with the Opengear's default network settings.



To change the DRAC's network settings, reboot the PowerEdge server. When the DRAC banner is displayed, press Ctrl-D.

Select Network Interface Properties. We suggest you use a static IP address rather than relying on a DHCP server, as this

eliminates a possible point of failure.



Enter 192.168.0.120 as the IP Address, 255.255.255.0 as the Netmask, 192.168.0.1 for the Gateway. Ensure the DRAC

NIC is set to Enabled. Enter 192.168.0.1 as the first DNS Server, the rest of the settings may be left at their factory

defaults.



Press r to save your changes and reboot the DRAC to apply the new settings.



Refer to the Dell documentation for other setup tasks such as configuring DRAC users. In this example we use the default

username/password, root/calvin.

Configuring the Opengear gateway for DRAC access

Ensure your Opengear unit is running firmware version 2.2.3 or later. The latest firmware is available from ftp.opengear.com
