How did you try to connect to the debug client. With "telnet IP 9000" ?

Which version of the debugclient were you testing?

debugclient is a simple test client that works in the same way as
netbeans would. However, netbeans adds a few more restrictions though.

It works like this:

1. You start the debugclient
2. You request a script in your browser with "http://.../?XDEBUG_SESSION_START=1
3. Browser connects to the webserver with PHP and Xdebug
4. If Xdebug sees the "XDEBUG_SESSION_START=?" it will connect to the
   debug client on the remote_port and remote_host that you have
   specified in php.ini
5. debugclient (or netbeans) issues commands
6. Xdebug responds
7. repeat step 5 and 6 until the script dies or ends.

You can test in other ways in the following matter.

After step 1: run "netstat -a -n | grep 9000" It should show:

tcp 0 0* LISTEN

You can test step 4 with a tool called wireshark, which analyses network
traffic. You should see connections being made from the webserver to
port 9000.
