помогите настроить ssh

пытаюсь приконектится на машиу со свеже проинсталеным Альтом, получаю ... ssh 192.168.1.10 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 12:33:c9:4f:dd:5d:ce:14:3f:fb:53:9d:2f:58:ac:0c. Please contact your system administrator. Add correct host key in /root/.ssh/known_hosts to get rid of this message. Offending key in /root/.ssh/known_hosts:5 RSA host key for 192.168.1.10 has changed and you have requested strict checking. Host key verification failed. Подскажите в чём дело ?? Всем спасибо.
