如何通过Node.js中的堡垒主机SSH到EC2实例

Question

我尝试了下面的代码，并使用了node-ssh-forward NPM软件包。

const SSHConnection = require('node-ssh-forward').SSHConnection

    var run = async () => {
        const ssh = new SSHConnection({
            username: 'Testuser', 
            endHost: 'example.com',
            bastionHost: 'bastion01.aws.cloud',
            privateKey: 'C:/Users/user/.ssh/id_rsa'
          })
         await ssh.executeCommand('uptime')
    }
    run()

错误消息：
