[SOLVED] Memcached in 2.1

[eluser]predat0r[/eluser]
Hi, I'm using CI 2.1 and trying to put some datas into memcached and retrieve it without success. I use Ubuntu and installed memcache and memcached. I can telnet into localhost to check if the caching working, I can add values manually then read them on console. And with netstat I see memcached is running and listening on port 11211.

If I use plain php oop commands to init and store / get datas, no probs, but using CI driver and commands always get bool/false.

Then I updated the Driver_memcached.php to the latest version (yesterday) from github, result is the same.

Using n0xie-s test method I always get the "Saving to the cache" message..

Code:

$this->load->driver('cache', array('adapter' => 'memcached', 'backup' => 'file'));

        $foo = $this->cache->get('testkey');

        if ( ! $foo )
        {
             echo 'Saving to the cache!<br />';
             $foo = 'test value';

             // Save into the cache for 5 minutes
             $this->cache->save('testkey', $foo, 300);
        }
        else
        {
            var_dump($foo);
        }

Using this example all goes well:

Code:

$memcache = new Memcache;
  $memcache->connect('localhost', 11211) or die ("Could not connect");

  $version = $memcache->getVersion();
  echo "Server's version: ".$version."<br/>\n";

  $tmp_object = new stdClass;
  $tmp_object->str_attr = 'test';
  $tmp_object->int_attr = 123;

  $memcache->set('key', $tmp_object, false, 10) or die ("Failed to save data at the server");
  echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";

  $get_result = $memcache->get('key');
  echo "Data from the cache:<br/>\n";

  var_dump($get_result);

My purpose is to use CI Driver, any idea what could the problem be?
Thanks

EDIT: I forgot to add memcached config file, thanks n0xie for the hint
