是否可以使用 node.js 使用 ssh2shell 或 simple-ssh 运行脚本？

Question

In a previous question, I asked if it was possible to run a telnet session from a remote SSH session using node.js. I usually connect to a linux server via an SSH putty session, and then telnet to another idirect / modem. I would like to do this programmatically using node.js. From the answer received, I understand that I must run an expect script to execute the required telnet commands.

Is it possible to run a script using ssh2shell or simple-ssh ?

Answer 1

It is totally doable, from what I understand in your question is that you want to connect via SSH to a server, and then run a script? Please elaborate a little bit.

There are some tools to run shell commands via Node.js : - ShellJS - Exec-sh

One thing to note is that those tools you have to port your script to their syntax, but they are still shell commands, they offer error handling too.

Answer 2

I used node-ssh.

You can connect to the instance, and you can use it like this:

let sshConnection = ssh.connect({
    host: <host>,
    username: <username>,
    privateKey: '/path/to/id-rsa'
  })

  sshConnection.then(() => {
    ssh.putFile('./script.py', '/tmp/script.py').then(() => {
      log('The File thing is done')
    }, (error) => {
      log('Somethings wrong', error)
    })
  })

  sshConnection.then(() => {
    ssh.execCommand(`echo hello-world`, { cwd: '/home' })
    .then((result) => {
      log(`result.stdout = ${result.stdout}`)
      log(`result.stderr = ${result.stderr}`)
    })
  })
