levels of authentication:
● rhost-authentication is done with the file specified in the ip ssh rhostfile command.
● checking client host-keys is done with the file specified in the ip ssh pub-key-file command.
NOTE: Administrators must specify the two files (rhosts and pub-key-file) to configure host-
based authentication.
