Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the RSA key sent by the remote host is f9:64:1a:19:11:85:d4:06:d9:47:7f:f7:da:50:8a:f9. Please contact your system administrator. Add correct host key in /Users/CPUU/.ssh/known_hosts to get rid of this message. Offending RSA key in /Users/CPUU/.ssh/known_hosts:2 RSA host key for 192.168.0.7 has changed and you have requested strict checking. Host key verification failed.
