Wating для подключения (netbeans-xdebug)

Я посетил несколько Howto и попробовал все из них - но все же я получаю страшное "Ожидание соединения" в Netbeans. Вот снимок моего окружения:

$ php -i

мой /etc/php5/cli/php.ini следующим образом:

$ sudo netstat -taupen

tcp   212534      0 192.168.0.5:34645       5.77.39.20:80           CLOSE_WAIT  1000       92048       19496/php 

192.168.0.5 моя локальная машина

$ telnet 192.168.0.5 9000

telnet: Unable to connect to remote host: Connection refused

$ sudo ufw status

Status: inactive

После нажатия кнопки "Отладка проекта" в IDE и обратно в терминал:

$ netstat -an | grep 9000

tcp6       0      0 :::9000                 :::*                    LISTEN 

И мой конфиг Netbeans:

В моих журналах ошибок PHP ничего нет. Можете ли вы определить, что я делаю неправильно или какие настройки я пропустил, используя приведенную выше информацию?

заранее спасибо

@rocky

Я не думаю, что я использую брандмауэр с

$ sudo ufw status
Status: inactive

В любом случае:

$ sudo iptables --list 
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination 

что не удивительно удобно для пользователя?
