I am using ssh2 package to ssh to a server.
By default when I connect to the server from cmd line, I don't have to pass in the password as we have ssh keys shared.
I connect at ssh abcuser#server and I am automatically connected.
But using ssh2, if I dont give password, it complains saying - Error: All configured authentication methods failed
Below is my code-
conn.exec(request.scriptName, function(err, stream) {
if(err){
logger.error('Failed to execute via ssh. ERROR: '+ err);
logger.exitAfterFlush(1);
}
stream.on('close', function(code, signal) {
conn.end();
}).on('data', function(data) {
let outputJson = JSON.parse(data.toString());
logger.info('Task Succeeded', {'output':outputJson});
logger.exitAfterFlush(0);
}).stderr.on('data', function(data) {
let details = {'details':data.toString()};
logger.error('Task Failed',{'output':details});
logger.exitAfterFlush(1);
});
});
}).connect({
host: request.hostName,
port: 22,
username: abcuser
});
Can anyone suggest how I can resolve this?

I can connect to ssh2 without the privateKey
I am trying to enter a server with SFTP but when I get the following error ...
Timed out while waiting for handshake
I'm looking for an example and almost everyone uses the privateKey, is it mandatory? and how is one generated?
My code is the following ...
var Client = require ('ssh2'). Client;
var conn = new Client ();
conn.on ('error', function (err) {
console.log ('SSH - Connection Error:' + err);
});
conn.on ('end', function () {
console.log ('SSH - Connection Closed');
});
conn.on ('ready', function () {
console.log ("------ enter ------");
// code to work with SSH
});
conn.connect ({
host: 'host',
username: 'user',
port: 22
password: 'password',
});
I am trying to make a connection to Postgres remote host using the SSH tunnel from node application(library:ssh2) and query the data(lib:pg).
Before I used mysql2(node library) make a tunnel using ssh2(node library) and connected to Mysql remote host as well as able to query the data. But I want to do the same in Postgres remote host I am not able to connect to it.
pg Client obj config does not support the stream from ssh2 forwardOut..!
Or, Is there any library available to make this happen instead of that ssh2, pg
PS: In mysql2 when I try to make a connection with a mysql config with stream: stream key value.
var Clientssh = require('ssh2').Client;
var conn = new Clientssh();
conn.on('ready', function() {
console.log('Client :: ready');
conn.forwardOut(
'127.0.0.1',
5434,
'localhost',
5432,
function(err, stream) {
if (err) throw err;
let conf = {
host: 'localhost',
port: 5434,
user: 'test',
database: 'test',
password: 'test'
}
let remoteConnection = new Client(conf);
remoteConnection.connect(function(err) {
if (err) {
console.log(err);
console.log("Unable to connect to postgre");
res.send(err);
} else {
remoteConnection.query('SELECT * FROM test', function(err, testResult) {
remoteConnection.end();
if (err) {
console.log("Unable to fetch data");
res.send(err);
} else {
console.log("Succcess");
res.send(testResult);
}
});
}
});
});
}).connect({
host: 'hostaddress',
port: 'hostport',
username: 'hostusername',
privateKey: require('fs').readFileSync('path/for/key')
});
It shows the Connection terminated unexpectedly from this line

Error: not opened at WebSocket.send
I have a piece of code on node server where i send the data to the game-server of my game.
pomelo.init({
host: rootTools.connectorHost,
port: rootTools.connectorPort,
log: true
}, function () {
var playerData = {any data of key value pair};
pomelo.request('connector.entryHandler.broadcastPlayer', {data: playerData, route: 'update', playerId: data.playerId}, function (err, data) {
console.log(err, data);
pomelo.disconnect();
});
});
While running on production there is a error Error: not opened
the console screenshot is -
[pomeloclient.init] websocket connected!
/home/digvijay/node_modules/ws/lib/WebSocket.js:181 else throw new
Error('not opened'); ^
Error: not opened at WebSocket.send

The pomelo.init worked well as on consoles the websocket is connected.
I didn't get the issue in the code. Kindly describe the expected cause and suggestions on how to resolve is any.
I am using node.js ssh2 module.I have installed ssh2 module by executing the command 'npm install ssh2'.However, when I use ssh2 to connect to a remote server, it always output the error:
[Error: All configured authentication methods failed] levels: 'client-authentication'
This is my code
var Client = require('ssh2').Client
var conn = new Client();
var option = {
host: '10.171.65.154',
port: 22,
username: 'root',
password: '123456'
};
conn.on('ready', function(){
console.log('Client :: ready');
conn.sftp(function(err, sftp){
if(err) throw err;
sftp.readdir('home', function(err, list){
if(err) throw err;
console.dir(list);
conn.end();
});
});
}).on('error', function(err){
console.log(err);
}).connect(option);
However, I can not connect successfully.I am sure the username and password are correct and I can connect successfully by SecureCRT.
it always output the error:
[Error: All configured authentication methods failed] levels: 'client-authentication'
Probably, you have to handle keyboard-interactive authentication (which is not the same as password). Try something like this:
connection.on('ready', function(){
console.log("Connected!");
}).on('error', function(err){
console.error(err);
}).on('keyboard-interactive', function (name, descr, lang, prompts, finish) {
// For illustration purposes only! It's not safe to do this!
// You can read it from process.stdin or whatever else...
var password = "your_password_here";
return finish([password]);
// And remember, server may trigger this event multiple times
// and for different purposes (not only auth)
}).connect({
host: "your.host.or.ip",
port: 22,
username: "your_login",
tryKeyboard: true
});
I can't connect to Redis using kue, I've followed this article, practically I'm creating the connection by using the kue redis client, and the connection code is this:
var kue = require('kue'),
redis = require('kue/node_modules/redis');
app.redisClient = redis.createClient('6379', 'remoteip',{});
app.redisClient.on('error', function (err) {
console.log('Redis error encountered', err);
});
app.redisClient.on('end', function() {
console.log('Redis connection closed');
});
kue.redis.createClient = function() {
console.log('client ------------------',app.redisClient);
return app.redisClient;
};
and it seems like Kue is trying to connect to a local Redis (which I don't have installed), because I'm getting this exception:
Error: Redis connection to 127.0.0.1:6379 failed - connect
ECONNREFUSED
I've read this post and it seems like the issue has been resolved in version 0.8 and I'm using 0.8.11 :/, finally I also wanted to override the client using a different client instance by using redis nodejs without any luck, because I'm getting the same error.
any help will be more than appreciated.
thanks!
I used a different way to setup the connection and it works so far this is what I've done:
app.redisClient = redis.createClient(config.redisPort, config.redisUrl,{});
app.redisClient.on('connect', function () {
console.info('successful connection to redis server');
});
app.redisClient.on('error', function (err) {
console.log('Redis error encountered', err);
});
app.redisClient.on('end', function() {
console.log('Redis connection closed');
});
kue.app.listen(config.kuePort);
app.jobs = kue.createQueue({
redis: {
createClientFactory: function(){
return app.redisClient;
}
}
});
