@ 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
95:77:10:66:e6:89:21:fe:46:25:5b:c2:b7:34:ec:92.
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:4
RSA host key for 172.17.3.136 has changed and you have requested strict checking.
Host key verification failed.
lost connection

bye

Problem can be fixed by reading the error message. In this case you already had a key from that host in the file in which has changed(reinstall, new key or actual attack).


Edit the /root/.ssh/known_hosts file and remove the host your trying to get to. When you try to connect again it will ask you if you want to add it.
