You can securely log in to Oracle SPARC Model 300 Service instances from a remote host using a secure shell (SSH) connection.
SSH is a cryptographic network protocol that can use a public key and a private key pair to provide secure communication between two computers. SSH uses network port 22 by default.
You can associate one or more SSH public keys with each instance, enabling secure communications from one or more hosts to one or more instances. Add each public key that is associated with an instance to the opc user accounts authorized_keys file located at /export/home/opc/.ssh/authorized_keys within an instance. SSH public keys are created as a text file (typically named id_rsa.pub), and you should append the contents of the public key file to the authorized_keys file and should not be edited in any way.
