Congure Public Key Authentication over SSH
You can congure up to 6 public keys that can be used with the service username over SSH interface. Before adding or deleting public
keys, be 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.
NOTE
: There is no GUI support for managing this feature; you can only use RACADM.
When adding new public keys, ensure 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 eect
as long as the SSH interface is enabled.
When using the public key comment section of the public key, remember that only the rst 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 since all PKA users
use the service username to log in.
For example, if two public keys are set up one with comment PC1 and one with comment PC2:
racadm getssninfo
