Netbeans waiting for connection to XDEBUG

On Ubuntu 13.04 64bit php 5.4.9-4 Xdebug v2.2.3 netbeans 7.4
I have same problem and have solve it by:
1. go on http://xdebug.org/wizard.php follow the instructions to compile your own xdebug.so
2. in netbean 7.4 general options (sorry I haven't reputation 10 to post image) test connection. be sure correct settings on Proxy: to me "No Proxy" is working.
3. in php options debugging tab change xdebug setting port to other than 9001 or 9000. I choose 9002 but you can try until you find a free port (if port is not free nb tell you)
4. in php.ini OR for ubuntu users in /etc/php5/conf.d/20-xdebug.ini

zend_extension=/usr/lib/php5/20100525/xdebug.so #where you ave put your reconpiled xdebug.so
[xdebug]
xdebug.remote_autostart=0
xdebug.remote_enable=1
xdebug.remote_handler="dbgp"
xdebug.remote_mode="req"
xdebug.remote_port=9002 # the port you have found free and set in netbeans above
xdebug.remote_host=127.0.0.1
xdebug.profiler_enable=0
xdebug.profiler_output_dir="/tmp/"
xdebug.idekey="netbeans-xdebug"
xdebug.remote_log="/home/#user_name#/xdebug.log" #your user name

5. sudo service apache2 restart

after do this I can debug php again.
