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

It is also possible that a host key has just been changed.

the RSA key sent by the remote host is

Please contact your system administrator.
Add correct host key
in
/root/
.
ssh
/known_hosts
to get rid of this message.

在网上找资料，原来这是Linux重装或者openssh-server重装引起的，执行以下命令即可
ssh-keygen -R 10.40.49.54
10.40.49.54换成你要连的服务器就可以了。
