connecting ssh server with private key in node js

Question

I am getting below error when connecting ssh server with identity file in node js

Error: Unable to read the Private Key File

my code:

    driver = require('node-ssh');

    ssh = new driver({
              host: '192.168.*.*',
              username: 'user',
              password: 'password',
              privateKey : require('fs').readFileSync('/tmp/my_key')
            });

    ssh.connect().then(function() {
           /*
       some code
        */

            },function(error) {
                console.log(error);

            });

But if i connect from my linux machine, it is connected.

ssh -i /tmp/my_key  [email protected].*.*

Please give any solution for this.

node-ssh expects the name of the private key file, instead of the contents (example from the node-ssh npm page):

ssh = new node_ssh({
  host: 'localhost',
  username: 'steel',
  privateKey: '/home/steel/.ssh/id_rsa'
});

Updated in the latest npm package, https://www.npmjs.com/package/node-ssh/v/13.1.0 Here, the privateKeyPath parameter is introduced if you give the path of your privateKey.

Example:

ssh.connect({
  host: 'localhost',
  username: 'steel',
  privateKeyPath: '/home/steel/.ssh/id_rsa'
})

// or with inline privateKey

ssh.connect({
  host: 'localhost',
  username: 'steel',
  privateKey: Buffer.from('...')
})
