【问题描述】：

我通常使用 VS Code 的 Remote-SSH 扩展来连接到我工作的 AWS 实例。他们的文档中有一个很好的部分关于如何做到这一点here。我讨厌单独使用终端，因为我喜欢调试器以及打开文件夹和文件进行查看的能力。直到最近，我一直从我的 MacBook Pro (A) SSH 到运行 Ubuntu 18.04.4 LTS (B) 的 AWS 实例，没有任何问题。但是，现在我需要处理一个新实例，也是 Ubuntu 18.04.4 LTS，(C)，我只能从 B SSH 进入，而不能从 A。

This part of the documentation 表示我可以从A SSH 到B，然后转发一个端口来创建一个SSH 隧道。但是，这只允许我在 C 中打开一个终端。但是，这不允许我在资源管理器中像我想要的那样打开文件夹和文件。

我已经按照秦升的指示here 设置了一个 SSH 隧道并使用 Remote-SSH 扩展的“ProxyJump”功能我的配置文件如下所示：

Host B
  HostName B.mydomain.com
  IdentityFile /Users/MyID/.ssh/B_private_key
  User me

Host C
  HostName C
  IdentityFile /Users/MyID/.ssh/C_private_key
  ProxyJump B
  User me

当我在 VS Code 上使用终端运行 ssh C 时，这非常有效。无需输入任何密码，我就会被带到 C 并可以执行我的工作。但是，当我尝试使用“远程 SSH：连接到主机”功能通过 B 使用 ProxyJump 通过 SSH 连接到 C 并随后在那里打开文件夹/查看文件时，我收到消息“无法建立与 'C' 的连接” ”。堆栈跟踪如下所示：

我似乎很清楚，主要问题是试图访问 /bin/false 作为解释器。我认为这是我的 MacBook Pro (A) 的问题。我确实注意到在 A 上运行 echo $SHELL 时它返回 /bin/false，但我运行 export SHELL=/bin/bash 来更改它并按照 this post 中的建议将 VS Code 的 MacOS 集成 shell 设置为 /bin/bash .我也在 B 上检查了echo $SHELL，它也同样显示了/bin/bash。

我的问题是：

我想要完成的事情可能吗？ 如果是，我做错了什么？/我可以检查什么来帮助确保我可以使用我想要的 VS Code 功能？

【参考方案1】：

我想通了。我的/etc/passwd 文件中有一堆/bin/false 引用，所以我将它们更改为/bin/bash，现在它就像一个魅力。 :)
