WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED

原文地址:http://linuxme.blog.51cto.com/1850814/375752

今天将阿里云服务器更换了一下系统盘,重启成功后,再次通过终端访问阿里云的公网IP报以下信息:

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

@    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

SHA256:gul+NDB/fihQee0WCsbRX5RuY8FQtN8CQN4F7Mi0nlw.

Please contact your system administrator.

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

Offending RSA key in /Users/idealist/.ssh/known_hosts:1

RSA host key for 60.205.150.104 has changed and you have requested strict checking.

Host key verification failed.

在网上找了解决方法,经实验,可用,遂记录一下备忘。

解决方法:

先cat一下本地目录的.ssh/know_hosts,命令如下:

cat ~/.ssh/known_hosts

会显示之前连接的信息:

公网的IP地址 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA7ajWUd/WHci2gMjGuum3W1DK3r1eXJcnp6ntAZ/jAAAcOvHg4awlqwOkyAUOqTtuJ6gUqBxoxUYiYdU1os6P5GxYm1G25CjfRaYLyW5bssgmnXKAraVi29bMP4NzjGdvLzv0j4b5+y4D7pXw8N2qbeLtOuOMa2VnoOO5YNir62xOLlmg4G9gUm0KvJ6xYNEVwekz29K8xDdQs9IA+t538umzetoDB54PgaHY7PPiYNJKuKiIr0absjHgQjAsSAgOCv83GkzQp23FO6T0PwMpSqxrRSWZniSWDS8rQgR3xjdVz1A6lFXZs6U5JqOJEFjs4Lgdd4/djQAzR4WUEOO1cw==

编辑此文件:

vim ~/.ssh/known_hosts

将这些信息删除并保存文件即可。
