SSH Keys
The SLC console 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 SLC 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 SLC configuration, and the administrator has the option of retaining the SSH keys during a
reset to factory defaults.
The SLC 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 SLC local user. The key can be generated on host
"MyHost" for user "MyUser," and when the key is imported into the SLC unit, it must be associated
with either "MyUser" (if "MyUser" is an existing SLC local user) or an alternate SLC 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 SLC console manager from the designated host/user
combination uses the SSH key for authentication.
