将 SSH 命令连接到标准输出 [英] Connect SSH command to stdout

问题描述

我正在创建一个命令行工具，它可以从我们的集群中动态查找服务器，然后根据集群检索保存在 Amazon s3 存储桶中的相应私钥，并将其复制到本地的临时文件以连接到服务器.

I am creating a command-line tool that dynamically finds a server from our cluster, then based on the cluster retrieves the appropriate private key held in an Amazon s3 bucket and copies it to a tempfile locally to connect to the server.

如何通过 SSH 连接到 IP 地址，然后允许用户与 SSH 会话进行交互?

How would I SSH into an IP address and then allow the user to interact with the SSH session?

此示例将打开一个到名为platform"的集群中一台机器的 ssh 会话:

This example would open a ssh session to a machine in the cluster named "platform":

company_name ssh:platform

我以前在 Ruby 中这样做过:

I've done this before in Ruby like so:

exec("ssh -i #{private_key_file.path} -R 52698:localhost:52698 core@#{platform_ip}")

推荐答案

你可能想看看 ssh2-rs 箱子；文档有一个很好的示例，说明您的情况努力完成.

You probably want to take a look at the ssh2-rs crate; the docs have a good example of what you're trying to accomplish.

它的要点是您获得一个 channel_session 对象，该对象具有从 SSH 控制台读取输出的方法(从此处的文档中复制):

The gist of it is that you get a channel_session object, which has methods to read the outputs from the SSH console (copied from the docs here):

let mut channel = sess.channel_session().unwrap();
channel.exec("ls").unwrap();
let mut s = String::new();
channel.read_to_string(&mut s).unwrap();
