The known_hosts file has nothing to do with host-based authentication. It is used to verify the identity of the host when using SSH with standard user-based authentication.

Generally speaking, using host-based authentication is highly discouraged for security reasons, but in an xCAT scenario it can make sense. _______________________________________________________________________ Kevin Keane | Systems Architect | University of San Diego ITS | [email protected] Maher Hall, 192 |5998 Alcalá Park | San Diego, CA 92110-2492 | 619.260.6859 | Text: 760-721-8339 *REMEMBER! **No one from IT at USD will ever ask to confirm or supply your password*.
