Logging In To Cmc Using Public Key Authentication; Multiple Cmc Sessions; Changing Default Login Password - Dell EMC PowerEdge VRTX User Manual

You can use remote RACADM commands in scripts to configure multiple CMCs. You cannot run the scripts directly on the CMC web
interface, because CMC does not support it.
For more information about RACADM, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line
Reference Guide.

Logging in to CMC Using Public Key Authentication

You can log in to the CMC over SSH without typing a password. You can also send a single RACADM command as a command line
argument to the SSH application. The command line options behave similar to the remote RACADM, because the session ends after
the command is completed.
Before logging in to CMC over SSH, make sure that the public keys are uploaded. To use this feature, you must have an Enterprise
License.
For example:
• Logging in: ssh service@<domain> or ssh service@<IP_address>, where IP_address is the CMC IP address.
• Sending RACADM commands: ssh service@<domain> racadm getversion and ssh service@<domain>
racadm getsel
When you log in using the service account, if a passphrase was set up when creating the public or private key pair, you may be
prompted to enter that passphrase again. If the passphrase is used with the keys, client systems running Windows and Linux provide
methods to automates the method. On client systems running Windows, you can use the Pageant application. It runs in the
background and makes entering the passphrase transparent. For client systems running Linux, you can use the ssh agent. For setting
up and using either of these applications, see their product documentation.

Changing Default Login Password

The warning message that prompts you to change the default password is displayed if:
• You log in to CMC with Configure Users privilege.
• Default password warning feature is enabled.
• Default user name and password for any currently enabled account are root and calvin respectively.
The same warning message is displayed if you log in using Active Directory or LDAP. Active Directory and LDAP accounts are not
considered when determining if any (local) account has root and calvin as the credentials. A warning message is also displayed
when you log in to CMC using SSH, Telnet, remote RACADM, or the Web interface. For Web interface, SSH, and Telnet, a single
warning message is displayed for each session. For remote RACADM, the warning message is displayed for each command.
To change the credentials, you must have Configure Users privilege.
NOTE: A CMC log message is generated if the Do not show this warning again option is selected on the CMC Login page.
