服務器重新安裝之后，從別的機器連接不上，并報以下錯誤

[root@zabbix ~]# ssh 10.0.0.11

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

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 the RSA host key has just been changed.

The fingerprint for the RSA key sent by the remote host is

e1:aa:44:6a:d2:b0:9c:18:ce:1e:8a:dc:b5:b0:83:01.

Please contact your system administrator.

Add correct host key in /root/.ssh/known_hosts to get rid of this message.

Offending key in /root/.ssh/known_hosts:12

RSA host key for 10.0.0.11 has changed and you have requested strict checking.

Host key verification failed.

這是Linux重裝或則openssh-server重裝引起的，執行以下命令即可
ssh-keygen -R?IP??

[root@zabbix ~]# ssh-keygen -R 10.0.0.11

/root/.ssh/known_hosts updated.

Original contents retained as /root/.ssh/known_hosts.old

把IP換成你要連的服務器就可以了。

[root@zabbix ~]# ssh 10.0.0.11 ? ? ? ? ?

Are you sure you want to continue connecting (yes/no)? yes
