H3C SSH报错：客户端保存的服务器公钥和服务器的实际公钥不一致

报错内容：

The server's host key does not match the local cached key. Either the server administrator has changed the host key, or you connected to another server pretending to be this server. Please remove the local cached key, before logging in!

Connection closed.

报错分析：
