Subject: [CentOS] SSH Authenticity Messages... Disable/

Greetings CentOS community!

I connect to a very large number of new machines with a handful of my
CentOS boxen. Whenever I connect to a new host, I *REALLY* would like to
*NOT* see the error message such as this:

The authenticity of host 'w.x.y.z (w.x.y.z)' can't be established.
RSA key fingerprint is 62:7a:6c:e5:03:f5:47:be:23:a5:c5:e5:c3:60:9b:8d.
Are you sure you want to continue connecting (yes/no)? yes

Also, some of these systems are being setup with an automated login
system via SSH keys which means I have to manually login to each of the
boxes before the automated scripting will work just to clear the
'authenticity' error.

Is there a way to disable this error/authenticity check globally for a
system? I understand it may not be the best practice in terms of
security, but for an internal trusted host, I have no reservations
making this change.

Help! :-)
