SSH:远程服务器关闭连接

Question

我正在尝试ssh登录到我的远程服务器.但每当我尝试使用ssh命令登录终端时:

  ssh root@{ip_address}

我收到错误:

 Connection closed by {ip_address}

我检查了主机拒绝和主机允许,文件中没有任何内容.我不知道为什么会这样？

它发生在我改变我的工作站和密钥改变了.当我尝试ssh登录时,它要求添加密钥,我输入yes然后它关闭了连接.

有没有办法再次与ssh联系？

非常感谢您的帮助.

谢谢.

Answer 1

遇到了同样的问题，但简单的远程服务器重新启动有帮助。

Answer 2

您确定您的服务器允许 root 通过 SSH 登录吗？如果没有，我建议使用具有权限的不同帐户sudo，而不是启用 root 登录 - 特别是如果可以从整个内网访问服务器的 SSH 端口。
