Node.js 错误：使用 ssh2 读取 ECONNRESET

Question

I am trying to use ssh2 from npm to setup an ssh connection and remotely login to a machine. The code works fine for Windows to Linux/MacOS connections but fails for Windows to Windows connection(the error screenshot has been attached). I did find something related to agent and agentForward parameters that might be causing the problem but couldn't find a solution to it. Node Version: 8.11.2
Any help would be appreciated! Thanks! The code is as follows:

app.get("/",function(req,res)
{
    var conn = new Client();
    conn.on('ready', function() 
    {
        console.log('Client :: ready');
        conn.exec('systeminfo', function(err, stream) 
        {//system_profiler SPHardwareDataType, systeminfo
            if (err) console.log(err);
            stream.on('close', function(code, signal) 
            {
            console.log('Stream :: close :: code: ' + code + ', signal: ' + signal);
            conn.end();
            }).on('data', function(data) 
            {
                console.log('STDOUT: ' + data);
            }).stderr.on('data', function(data) 
            {
                console.log('STDERR: ' + data);
            });
        });
    }).connect({
    host: '127.0.0.1',
    port: 22,
    username: 'inspiron',
    privateKey: require('fs').readFileSync('C:/Users/inspiron/Downloads/private_key.ppk')
    });
    res.send(str);
});

This is the Error Message:

Answer 1

I have also similar problem.

events.js:183
      throw er; // Unhandled 'error' event
      ^

Error: read ECONNRESET
    at _errnoException (util.js:992:11)
    at TCP.onread (net.js:618:25)

Though I added some delay and it somehow works.

stream.on('close', function(code, signal){
  console.log('Stream :: close :: code: ' + code + ', signal: ' + signal);
  //extra lines of code here..
  conn.end();
}

Add some delay or try-catch statement; also with "stream.on('data', function(data) {...

stream.on('close', function(code, signal){
  console.log('Stream :: close :: code: ' + code + ', signal: ' + signal);
  //var newvar = oldvar;

  setTimeout(function() {
    conn.end();
    //use the newvar here..
    //extra lines of code..
  },100);
}

Answer 2

I had to give up on the above approach ie using ssh2 since I couldn't find a solution for the error being faced.

What I did instead was to run powershell scripts:

• The first script simply ran the Test-Connection cmdlet to check whether the machine at a given IP address was reachable or not.
• Next, a powershell script was run on the host machine using child-process in Node.js to get the required parameters(such as Hostname, RAM, OS etc.) from the remote machine which should be a Windows machine.
• If the second script was not run on a windows machine, it would fail with an error and then a third powershell script would run which has been made specifically for Linux based machines.
