Ubuntu-ssh --警告:远程主机标识已更改
提问于 2011-12-28 17:28:55
我无法通过ssh和rysnc连接到远程系统。它不断地给出这个错误消息：
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]我已经从/home/user/.ssh中删除了authorized_keys文件。

消息上写的是"/root/.ssh/known_hosts“而不是authorized_keys。从该文件中删除该文件(或至少相应的密钥)，然后可以再次执行操作！但请注意:密钥更改肯定是有原因的。系统是否重新安装？请确保检查这一点，否则ssh的整个概念都是无效的。
顺便说一句，你以root身份ssh有什么原因吗？

您可以使用sed从known_hosts文件中删除8行的有问题的键：
