SSH2 PHP stopped working

RA4W · May 12, 2014

So basically ive been using this for atleast 5 months now and its been all fine now just a few days ago it just stopped working no changes has been made and i dont think any updates would cause this? as i havent done any changes at all.

$connection = ssh2_connect('ip', 22);

ssh2_auth_password($connection, 'root', 'oo');

$cmd = ssh2_exec($connection, 'useradd '.$username.' -s /bin/false; echo -e "'.$password.'\n'.$password.'" | passwd '.$username.'');

So basically what happens is that it connect just nicely but it changes the root password? extremely wierd i would appreciate any help i could get as i am clueless.

Code:

<?php
ini_set('max_execution_time', 60);
define("_VALID_PHP", true);

if (isset($_POST['create'])) {
	$username = $_POST['user_id'];
	$password = $_POST['password'];
  

	// server 1 cmd
	$connection = ssh2_connect('ip', 22);
	ssh2_auth_password($connection, 'root', 'pw');
	$cmd = ssh2_exec($connection, 'useradd '.$username.' -s /bin/false; echo -e "'.$password.'\n'.$password.'" | passwd '.$username.'');
	
}
?>

Where do you use this code? Any links?

Might I suggest switching to phpseclib, it's so much easier to use and has built in debugging. Here's your same script using phpseclib (I used my own code for the adduser part, because I know it works):

Code:

<?php
ini_set('max_execution_time', 60);
define("_VALID_PHP", true);
include('Net/SSH2.php');

if (isset($_POST['create'])) {
	$username = $_POST['user_id'];
	$password = $_POST['password'];

	// server 1 cmd
	$ssh = new Net_SSH2('ip');
	if (!$ssh->login('root', 'pw')) {
		exit('Login Failed');
	}
	echo $ssh->exec('pwd');
	echo $ssh->exec('pwd');
	$ssh->exec('/usr/sbin/adduser '.$username.' -s /bin/false');
	$ssh->exec('echo -e "'.$password.'\n'.$password.'" | passwd '.$username.'');
	#echo $ssh->getLog(); //uncomment for debugging
	
}
?>
