IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle

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

Please contact your system administrator.
Add correct host key in /home/user/.ssh/known_hosts to get
rid of this message.
Offending key in /home/user/.ssh/known_hosts:1
RSA host key for user.server has changed and you have requested strict

Host key verification Failed.
ssh-keygen -R hostname
这将从known_hosts中删除违规键
手册页条目如下：
-R hostnameRemoves all keys belonging to hostname from a known_hosts file. This option is useful to delete hashed hosts (see the -H option above).
