Adduser Linux

[kekkoa7x]

Salve a tutti,
Ho creato questo piccolo codice per la creazione di un user in linux in fase di registrazione utente.

    function Register($post, $process) {

        if(isset($process)) {

        $pass1            = $post['pass1'];
        $pass2            = $post['pass2'];
        $username        = $post['username'];
        $email_address    = $post['email_address'];
        $first_name        = $post['first_name'];
        $last_name        = $post['last_name'];
        $info            = $post['info'];
        $porta            = $post['porta'];
        $host            = $post['host']; 
        
        if((!$pass1) || (!$pass2) || (!$username) || (!$email_address) || (!$first_name) || (!$last_name) || (!$info) || (!$porta) || (!$host)) {
        return "Some Fields Are Missing";
        }
        if ($pass1 !== $pass2) {
        return "Passwords do not match";
        }
        $query = $this->query("SELECT username FROM ".DBTBLE." WHERE username = '$username'");
        if($query['num_rows'] > 0){
        return "Username unavialable, please try a new username";
        }
        $query = $this->query("SELECT email_address FROM ".DBTBLE." WHERE email_address = '$email_address'");
        if($query['num_rows'] > 0){
        return "Emails address registered to another account.";
        }
$comand = "/usr/sbin/useradd -m -p $pass1 $username";
$connection = ssh2_connect('IPSERVER', 22);
ssh2_auth_password($connection, 'USERROOT', 'PASSWORDROOT');
$stream = ssh2_exec($connection, $comand);
if (!$connection) die('Connection failed');
        $this->query("INSERT INTO ".DBTBLE." (first_name, last_name, email_address, username, password, info, porta, host) VALUES ('$first_name', '$last_name', '$email_address', '$username', '".md5($pass1)."', '".htmlspecialchars($info)."', '$host', '$porta')");
        return 'User was created.';
    }
    } 

L'user viene creato con successo l'unico problema che la password non è corretta.Non so più cosa provare.

Grazie per l'aiuto che mi darete.
