s5130交换机ssh配置无法被远程

交换机配置ssh远程后，其中有一台无法被远程（一开始能远程几秒钟，后面突然断了），再次连接就秒断开，换多种shell工具都是这样.

甚至用核心、汇聚乃至接入远程该交换机都远程，在输入密码后停止远程了。

1. 用powershell远程提示如下：

PS C:\Windows\system32> ssh 10.10.10.10

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

@    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:WRziA0xF2niAwoW/u3MezWuJjqOFGvRIl890j5wVAmQ.

Please contact your system administrator.

Add correct host key in C:\\Users\\ausu/.ssh/known_hosts to get rid of this message.

Offending RSA key in C:\\Users\\ausu/.ssh/known_hosts:1

RSA host key for 10.10.10.10 has changed and you have requested strict checking.

Host key verification failed.

2. 交换机远程如下：

<H3C>ssh 10.10.10.10

Username: admin

Press CTRL+C to abort.

Connecting to 10.10.10.10 port 22.

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!
