This is a one-off the first time you use ssh with a given remote
machine.  Your machine keeps track of a cryptographic fingerprint that
belongs to the given server (have a look in ~/.ssh/known_hosts).  If one
day you ssh to that machine and the fingerprint is different, you get a
big warning and the connection is terminated.  The reason for this is it
can mean someone has tricked you into connecting to an evil machine
instead of the one you think you're connecting to, by poisoning your DNS
or messing with ARP or whatever.  It's not likely to happen for two
machines in the same room, but it could happen so ssh protects against
it like this.

You'll also see this if you ever reinstall the OS on the server you're
connecting to, it will have a different, random fingerprint after that too.

Anyway, you won't see the "authenticity" error above again for that
machine because your machine has remembered the fingerprint that belongs
to that IP address.
