我正在尝试使用node.js通过ssh在我的Linux服务器中发出命令行。我找到了这个https://github.com/mscdex/ssh2并尝试测试。这是我的代码，ready事件永远不会被触发：
var Client = require('ssh2').Client;
console.log('Start ssh2...');
var conn = new Client();
conn.on('ready', function() {
console.log('Client :: ready');
conn.shell(function(err, stream) {
if (err) throw err;
stream.on('close', function() {
console.log('Stream :: close');
conn.end();
}).on('data', function(data) {
console.log('STDOUT: ' + data);
}).stderr.on('data', function(data) {
console.log('STDERR: ' + data);
});
stream.end('ls -l\nexit\n');
});
}).connect({
host: '12.12.12.12',
port: 22,
tryKeyboard: true,
debug: console.log,
readyTimeout: 99999,
username: 'root',
password: 'password'
});
我设置了长readyTimeout和tryKeyboard为真。

但是，如果我将ssh服务器配置更改为在node.js服务器中拥有私钥，则可以进行身份验证。我的问题是为什么用户名/密码验证不起作用以及如何解决它（我的代码或更改服务器配置不知何故）？
