Congure public key authentication over SSH
You can congure 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.
NOTE: There is no GUI support for managing this feature, you can use only the RACADM.
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 eect
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, because all the 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

Connect one end of the serial null modem cable (present at both ends) to the serial connector on the back of the chassis. Connect the
other end of the cable to management station serial port. For more information on connecting cables, refer to the back panel of the chassis
