ssh远程主机标识已更改 [英] ssh remote host identification has changed

问题描述

我已重新安装服务器，并收到以下消息:

I've reinstalled my server and I am getting these messages:

[user@hostname ~]$ ssh root@pong
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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
6e:45:f9:a8:af:38:3d:a1:a5:c7:76:1d:02:f8:77:00.
Please contact your system administrator.
Add correct host key in /home/hostname /.ssh/known_hosts to get rid of this message.
Offending RSA key in /var/lib/sss/pubconf/known_hosts:4
RSA host key for pong has changed and you have requested strict checking.
Host key verification failed.

我尝试了在Internet上找到的各种解决方案.我的known_hosts文件(通常在~/.ssh/known_hosts中)在/var/lib/sss/pubconf/known_hosts中.我试图对其进行编辑，但它仍处于一种状态.我已经安装了 ipa-client ，并安装了Fedora19.如何解决此警告?

I have tried various solutions that I found on the Internet. My known_hosts file (normally in ~/.ssh/known_hosts) is in /var/lib/sss/pubconf/known_hosts. I've tried to edit it, but it remains in one state. I have installed ipa-client and have Fedora 19. How do I resolve this warning?

到目前为止，所有答案都只有在没有安装Freeipa的情况下才有效.

在adrin下方的评论中，freeipa的正确答案是在此处.

推荐答案

这是最简单的解决方案

ssh-keygen -R <host>

例如，

ssh-keygen -R 192.168.3.10

来自 ssh-keygen手册页:

• -R hostname从known_hosts文件中删除所有属于主机名的密钥.此选项对于删除散列主机很有用(请参见上面的-H选项).

• -R hostname Removes all keys belonging to hostname from a known_hosts file. This option is useful to delete hashed hosts (see the -H option above).
