Ways to manage SSH for SecureAdmin

SecureAdmin uses options to enable secure sessions using SSH. The options enable you to control password-based authentication and public key authentication, control access to a storage system, and assign the port number to a storage system.

SecureAdmin uses the following options to enable secure sessions using SSH:

• options ssh.passwd_auth.enable—Controls password-based authentication.
• options ssh.pubkey_auth.enable—Controls public key authentication.
• options ssh.access—Controls access to a storage system.
• options ssh.port—Assigns the port number to a storage system.

• Setting up and starting SSH
  The SSH setup process involves creating host and server keys.
• Reinitializing SSH
  Reinitializing SSH enables you to change the sizes of existing host and server keys.
• Disabling or enabling SSH service
  You disable or enable SSH to stop or start SSH service, respectively.
• Public-key-based authentication
  Setting up key-based authentication requires an RSA key pair (a private and public key) in addition to the host and server keys. Public-key-based authentication differs between the two versions of SSH; SSH 1.x uses an RSA key pair and SSH 2.0 uses a DSA key pair in addition to an RSA key pair. For both versions of SSH, you must generate the key pairs and copy the public key to the storage system.
