Information
If you enable this command, clients can login without a password prompt. This
provides two 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.
