I installed Xdebug and all was fine, until suddenly it stopped working. phpinfo() gives a nice XDebug output with all variables. 

php -m | grep deb

also gives twice XDebug (for Zend and PHP), so again looks just fine. My php.ini has these lines: 

zend_extension=/usr/lib/php5/20090626/xdebug.so
;extension=xdebug.so
xdebug.remote_host=localhost
xdebug.remote_enable=on
xdebug.remote_port=9001
xdebug.remote_handler=dbgp
xdebug.remote_connect_back=1

And yet, when running this code with should check XDebug (from Netbeans docs) it’s just stuck. So No IDE is working with XDebug. 

<?php
$address = '127.0.0.1';
$port = 9001;
$sock = socket_create(AF_INET, SOCK_STREAM, 0);
socket_bind($sock, $address, $port) or die('Unable to bind');
socket_listen($sock);
$client = socket_accept($sock);
echo "connection established: $client";
socket_close($client);
socket_close($sock);

Also, according to XDebug installation, I went twice throught the steps. What is wrong with my config? Thanks.

    At the end, left with only two solutions – to reinstall the Ubuntu OS or to install a new VM especially for xdebug, I’m going for the second one.
    Funny thing is, everything was working according to the “RTM” (f=freaking). One thing that I couldn’t figure out is how to read the logs for XDebug in order to understand where the real problem is.

    UPDATE

    After some struggling, I deleted every single line related to xdebug from every php.ini that I had. And moved these lines to /etc/php5/conf.d/xdebug.ini. Restarted Apache, and then PHPStorm, and it works.
    P.S. in the middle, I tried to install xdebug with pecl, from github, and the standard Ubuntu version. I think the one that I compiled is currently working. And.. the log gets updated as well.

    ;xdebug configuration
zend_extension = /usr/lib/php5/20090626/xdebug.so
xdebug.remote_host = 127.0.0.1
xdebug.remote_enable = 1
xdebug.remote_port = 9000
xdebug.remote_handler = dbgp
xdebug.remote_mode = req
xdebug.profiler_enable=0
xdebug.profiler_enable_trigger=1
xdebug.remote_autostart=1
xdebug.idekey=PHPSTORM
xdebug.remote_log="/tmp/xdebug.log"
