Dell Chassis Management Controller Version 2.0 for PowerEdge FX2 and FX2s User's Guide

Configure public key authentication over SSH

You can configure up to six public keys that can be used with the service username over an SSH interface. Before adding or deleting public keys, make sure to use the view command to see what keys are already set up, so that a key is not accidentally overwritten or deleted. The service username is a special user account that can be used when accessing the CMC through SSH. When the PKA over SSH is set up and used correctly, you need not enter username or passwords to log in to the CMC. This can be very useful to set up automated scripts to perform various functions.

When adding new public keys, make sure that the existing keys are not already at the index, where the new key is added. CMC does not perform checks to ensure previous keys are deleted before a new one is added. As soon as a new key is added, it is automatically in effect as long as the SSH interface is enabled.

When using the public key comment section of the public key, remember that only the first 16 characters are utilized by the CMC. The public key comment is used by the CMC to distinguish SSH users when using the RACADM getssninfo command, because all the PKA users use the service username to log in.
