350 Configuring Security Features

administrators have disabled all local iDRAC6 users and allow only Microsoft

Active Directory directory service users to log in to the iDRAC6, and the

Active Directory authentication infrastructure subsequently fails, the

administrators may be unable to log in. Similarly, if administrators have

disabled all local configuration and place an iDRAC6 with a static IP address

on a network that already includes a Dynamic Host Configuration Protocol

(DHCP) server, and the DHCP server subsequently assigns the iDRAC6

IP address to another device on the network, the resulting conflict may

disable the out-of-band connectivity of the DRAC, requiring administrators

to reset the firmware to its default settings through a serial connection.

Disabling iDRAC6 Virtual Console

Administrators can selectively disable the iDRAC6 remote Virtual Console,

providing a flexible, secure mechanism for a local user to work on the system

without someone else viewing the user’s actions through Virtual Console.

Using this feature requires installing the iDRAC managed node software

on the server. Administrators can disable Virtual Console using the

following command:

racadm LocalConRedirDisable 1

The command LocalConRedirDisable disables existing Virtual Console

session windows when executed with the argument 1

To help prevent a remote user from overriding the local user's settings,

this command is available only to local RACADM. Administrators can use

this command in operating systems that support RACADM, including

Microsoft Windows Server 2003 and SUSE Linux Enterprise Server 10.

Because this command persists across system reboots, administrators must

specifically reverse it to re-enable Virtual Console. They can do so by using

the argument 0:

racadm LocalConRedirDisable 0
