Ubuntu 上的 Hortonworks SSH 问题：ssh_exchange_identification：连接被远程主机关闭

Question

我试图研究类似的问题，但 none 的解决方案可以解决我的问题。

我在 Ubuntu 16.04 LTS 上的 Virtualbox 上使用 Hortonworks HDP 2.6.5 沙箱。 Hortonworks 是运行，我在 VirtualBox 上显示了以下内容：

按照说明，我使用本地主机上的 4200 端口通过以下命令进行 ssh：

ssh [user]@127.0.0.1 -p 4200

这导致我出现以下错误：

ssh_exchange_identification: Connection closed by remote host

我试过调试，我得到以下日志：

OpenSSH_7.2p2 Ubuntu-4ubuntu2.4, OpenSSL 1.0.2g  1 Mar 2016

如果有人能帮助解决这个问题，我将不胜感激。

谢谢

HDP Sandbox 控制台中关于 SSH 访问的说明具有误导性。端口 4200 对于使用浏览器使用 HTTP 协议的 shell 访问很有用，因此不适用于命令行 ssh。请注意日志末尾的 'HTTP/1.1 400 Bad Request' 错误消息。尝试端口 2222，如下所示：

提示> ssh root@localhost -p 2222
