Windows11通过CMD连接VPS时出现：IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY

问题描述

在Windows的CMD命令窗中通过SSH连接远端Ubuntu服务器时出现：

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 SHA256:farAOz027tqMij71AVI8n7R8zcl7NqLf1Htt2MygvIY. Please contact your system administrator. Add correct host key in C:\\Users\\user1/.ssh/known_hosts to get rid of this message. Offending ECDSA key in C:\\Users\\user1/.ssh/known_hosts:13 Host key for 207.246.99.239 has changed and you have requested strict checking. Host key verification failed.

解决方案：

由于Ubuntu服务器重新安装导致。SSH host key for the server you’re trying to connect to has changed

通过如下命令重新发行KEY即可：

ssh-keygen -R 123.123.133.123

ℹ️ 将 IP 更换成自己服务器的IP即可
