I have vpn access, so i can ssh to server by following command from terminal
ssh qa-trinath01.my-qa
Its working fine from terminal.
But from nodejs, its not working. my code is
var express = require("express");
var app = express();
var node_ssh = require('node-ssh')
var
ssh = new node_ssh()
ssh.connect({
host: 'qa-trinath01.my-qa',
username: 'tanantham',
port: 27017,
privateKey: '/Users/tanantham/.ssh/id_rsa'
}).then(function() {
console.error('Success: ');
}).catch((error) => {
console.error('ERROR: ', error);
});;
app.listen(3001);
I am getting output as
ERROR: { Error: getaddrinfo ENOTFOUND qa-trinath01.my-qa qa-trinath01.my-qa:27017
at errnoException (dns.js:50:10)
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:92:26)

syscall: 'getaddrinfo',
hostname: 'qa-trinath01.my-qa',
host: 'qa-trinath01.my-qa',
port: 27017,

Can some one suggest the nodejs code to connect to ssh, i have only ssh key and ssh server name details.
ssh key -> /Users/tanantham/.ssh/id_rsa
server name -> qa-trinath01.my-qa
Have you tried to replace 'privateKey' with 'password' and enter your password.
It's probably not the most secure but it normally works.
Unless you have to use your private key from id-rsa
ssh = new node_ssh()
ssh.connect({
host: 'qa-trinath01.my-qa',
username: 'tanantham',
port: 27017,
password: 'YourPasswordHere'
}).then(function() {
console.error('Success: ');
}).catch((error) => {
console.error('ERROR: ', error);
});;
app.listen(3001);

I'm using a vServer from Ionos for a little project. I installed a MariaDB and NodeJS. Currently I'm trying to connect them both. Here is my code:
const mariadb = require('mariadb');
const pool = mariadb.createPool({
host: 'localhost',
user:'root',
password: 'xxxxxxxxx',
database: 'christmastrees',
connectionLimit: 5,
});
async function asyncFunction() {
let conn;
try {
conn = await pool.getConnection();
const rows = await conn.query("SELECT * from bäume");
console.log(rows); //[ {val: 1}, meta: ... ]
} catch (err) {
throw err;
} finally {
if (conn) return conn.end();
}
}
But when executing the file (node app), I get an error message after a few seconds
Error: connect ECONNREFUSED 127.0.0.1:3306
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1157:16)

So I searched for help and after 2 hours I literally found only one Idea. I added this line of code to my connection...
port: '/var/run/mysqld/mysqld.sock'
I tryed again to use node app, but this time I didn't get an error message, it is loading forever and nothing happens.
I would be so grateful for any help...
So I found the solution to my problem.
I checked if my MariaDB Service is even running and no it wasn't ^^
I am trying to make a simple connection between my nodejs server and my mysql db (using Microsoft SQL server manager studio v14), below is my code and the error message appearing in my console window.
here is my code:
var express = require('express');
var app = express();
var sql = require("mssql");
app.get('/', function (req, res) {
// config for your database
var config = {
user: 'superadmin',
password: '***',
server: 'localhost',
database: 'XXX'
};
// connect to your database
sql.connect(config, function (err) {
if (err) console.log(err);
// create Request object
var request = new sql.Request();
// query to the database and get the records
request.query('select * from Schools', function (err, recordset) {
if (err) console.log(err)
// send records as a response
res.send(recordset);
});
});
});
var server = app.listen(5000, function () {
console.log('Server is running..');
});
The error I am getting looks like this:
Server is running..

I am rather new at this particularly with dealing with databases. Can someone explain what the error means?
Add this line to the config:
options: {
encrypt: false
}
It will finally look like:
var config = {
user: 'superadmin',
password: '***',
server: 'localhost',
database: 'XXX' ,
options: {
encrypt: false
}
};
try to put encrypt: false in your config{}, it will work.
your error:
ConnectionError: Failed to connect to localhost:1433 - Could not
connect (sequence)
My problem was resolved by adding port
var config = {
user: 'superadmin',
password: '***',
server: 'localhost',
database: 'XXX',
port: '',
};
I used nodemailer and my code as follows:
const nodemailer = require('nodemailer');
module.exports = function(obj) {
return new Promise((resolve, reject) => {
console.log('In root to mail send file...');
let transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: 'myemail#gmail.com',
pass: 'my password'
}
});
let mailOptions = {
from: '<myemail#gmail.com>', // sender address
to: obj.email, // list of receivers
subject: obj.subject, // Subject line
text: obj.msg, // plain text body
html: obj.html_msg // html body
};
console.log('sending function');
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
console.log('Error due to send mail' + error);
reject(error);
} else {
console.log('Message %s sent: %s', info.messageId, info.response);
resolve(info);
}
});
});
}
When I run the code, I got this error
{

You could be behind a network proxy which could be causing a timeout error.

What's wrong with the following Server.JS file? We are trying to connect Deployd to Heroku and keep getting the following error. We're using Nitrous, and I have configure the mongoDB port to 5000. Any help is appreciated. Thanks a ton!
Server.JS

// start the server
server.listen();

You are using same port for two servers.
You can kill one of them with that command
netstat -ano|findstr "PID :5000"
5000 is your port.
