Add correct host key in /home/diadicic/.ssh/known_hosts to get rid of this message. Offending key in /home/diadicic/.ssh/known_hosts:2 RSA host key for 172.16.12.200 has changed and you have requested strict checking. Host key verification failed.

Delete the 2nd entry in /home/diadicic/.ssh/known_hosts
It will then ask you to add the correct entry the next time you connect.
IF it continues to complain, then something bad could be happening....
