[ssh2] problem z scp Opcje

[magra]

Witam
Mam taki skrypcik do backupu bazy. Wszystko gra do momentu, kiedy wywoluje komende 'scp' (linia 36) - w tym momencie skrypt sie zatrzymuje - normalnie scp powinno zapytać o hasło.

[PHP] pobierz, plaintext 
<?php
if(!($shell = ssh2_shell($sshc, 'xterm'))){
        echo "[error] unable to establish shell", PHP_EOL;
    } else {
 
        echo "[info] shell established. starting commands.", PHP_EOL;
        usleep(500000);
 
        stream_set_blocking( $shell, true );
 
        /*
        * sending commands
        */
        if ($server['su_pass'] !== '')
        {
            fwrite($shell, 'su' . PHP_EOL);
            fwrite($shell, $server['su_pass'] . PHP_EOL);
        }
 
        fwrite($shell, "rm -rf {$server['remote_backup_dir']};" . PHP_EOL);
        fwrite($shell, "mkdir {$server['remote_backup_dir']};" . PHP_EOL);
        
        $mysqlhotcopy_options = '';
        if ($server['mysql_user'] !== '')
        {
            $mysqlhotcopy_options = " --user={$server['mysql_user']} ";

        if ($server['mysql_pass'] !== '')

        }
