[K12OSN] should I be worried about this?

[Brian Chase]

If the server was rebuilt and new SSH keys generated, this message is 
normal.  You can fix this by going to your $HOME/.ssh directory and 
deleting known_hosts file.

If the server that you trying to connect to has NOT been rebuilt, your 
security was probably compromised, suggest new ssh-keygen.
