If you re-install your server a new server private key
/etc/ssh/ssh_host_rsa_key will be generated.
So when this got an IP number you have used before,
you will see that message.
It is the program "ssh" which is warning you.

If you know that the server has been changed,
then remove the line with that ip number,
and the warning is gone.
If the server has not been changed by someone you know,
then you are in trouble with that server.
