[kiosk@fundation20 ~]$ ssh root@172.25.20.1 -X @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 a host key has just been changed. The fingerprint for the RSA key sent by the remote host is e6:08:b3:4c:c5:ed:f6:51:b0:68:aa:0a:2e:9a:02:28. Please contact your system administrator. Add correct host key in /home/kiosk/.ssh/known_hosts to get rid of this message. Offending RSA key in /home/kiosk/.ssh/known_hosts:9 RSA host key for 172.25.20.1 has changed and you have requested strict checking. Host key verification failed.
