SSH Keys
The SLB branch office manager can import and export SSH keys to facilitate shared key
authentication for all incoming and outgoing SSH connections. By using a public/private key pair, a
user can access multiple hosts with a single passphrase, or, if a passphrase is not used, a user
can access multiple hosts without entering a password. In either case, the authentication is
protected against security attacks because both the public key and the private key are required to
authenticate. For both imported and exported SSH keys, the SLB unit supports both RSA and DSA
keys, and can import and export keys in OpenSSH and SECSH formats. Imported and exported
keys are saved with the SLB configuration, and the administrator has the option of retaining the
SSH keys during a reset to factory defaults.
The SLB device can also update the SSH RSA1, RSA and DSA host keys that the SSH server
uses with site-specific host keys or reset them to the default values.
Imported Keys
Imported SSH keys must be associated with an SLB local user. The key can be generated on host
"MyHost" for user "MyUser," and when the key is imported into the SLB, it must be associated with
either "MyUser" (if "MyUser" is an existing SLB local user) or an alternate SLB local user. The
public key file can be imported via SCP or FTP; once imported, you can view or delete the public
key. Any SSH connection into the SLB branch office manager from the designated host/user
combination uses the SSH key for authentication.
Exported Keys
The SLB unit can generate SSH keys for SSH connections out of the SLB device for any SLB
user. The SLB branch office manager retains both the private and public key on the SLB unit, and
makes the public key available for export via SCP, FTP, or copy and paste. The name of the key is
used to generate the name of the public key file that is exported (for example, <keyname>.pub),
and the exported keys are organized by user and key name. Once a key is generated and
exported, you can delete the key or view the public portion. Any SSH connection out of the SLB
branch office manager for the designated host/user combination uses the SSH key for
authentication.
