ssh 无法远程连接

ssh 无法远程连接

在一台主机远程重装系统后，本地中控机无法ssh远程连接，报错信息如下：

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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 ED25519 key sent by the remote host is
c0:25:0b:11:18:0d:52:78:4e:80:83:a2:75:79:e1:d9.
Please contact your system administrator.
Add correct host key in /home/fengquande/.ssh/known_hosts to get rid of this message.
Offending ED25519 key in /home/fengquande/.ssh/known_hosts:44
ED25519 host key for 10.173.130.165 has changed and you have requested strict checking.
Host key verification failed.

这是因为在之前连接时本地保存了目标服务器的公钥，在远程连接时发现公钥不匹配，抛出错误。

解决方法，进入.ssh目录下，删除nown_hosts里面那台主机的ip地址即可。
