Ubuntu-ssh – – 警告：远程主机标识已更改[已关闭]

我无法ssh和rysnc到远程系统。它不断给出这个错误信息：

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
a3:8f:7c:07:c9:12:d8:aa:cd:c2:ba:b3:27:68:bc:c2.
Please contact your system administrator.
Add correct host key in /root/.ssh/kNown_hosts to get rid of this message.
Offending RSA key in /root/.ssh/kNown_hosts:8
RSA host key for xxx.xxx.xxx.xxx has changed and you have requested strict checking.
Host key verification Failed.
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(601) [sender=3.0.8]

我删除了authorized_keys文件从/home/user/.ssh。

消息说“/root/.ssh/kNown_hosts”不是authorized_keys。
删除该文件(或至少相应的键)从它，你可以再去！但要注意：必须有一个原因为什么密钥改变。系统是否重新安装？确保你检查或者ssh的整个想法是无效的。

BTW：有什么原因你ssh作为根？
