I have followed all the FAQs carefully and cannot get the debugger to work remotely on a 3rd party server (Apache/PHP4.4 on Linux). I get an error that states:

"Failed to start debugger session. Please verify if debugger is installed on the server that corresponds to ...."

What I've done:

1) followed instructions on setting up the Debugger on PHP4
2) edited the php.ini to have the [Debugger] section, including adding my IP to the hosts_allowed "debugger.hosts_allow=localhost 192.168.0.251"
3) restarted apache, and used phpinfo. I can see the following: "Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies with DBG v3.1.8, (C)"
4) Followed the instructions for Troubleshooting Debugger Connections. I can telnet into my IP from the server on port 7869 and the DBG Listener will correctly detect a connection from the server.

Are there any other debugging steps I can try to see what's wrong?

Thanks

well, try to launch say info.php that continains phpinfo() call using regular browser. URL should be like this: http://myserver/info.php?DBGSESSID=1
and check if there are any errors shown in the browser output, check Apache logs and check DbgListener log.

dmitri, if I create the info file and run it I see a regular phpinfo() output with nothing special. I still see:



In the DBG section I see the following:



I have reread the help FAQs just in case I'm missing something. I do notice that it says debugger.enabled "Off" in the phpinfo but my debugger section in php.ini is very explicit in having that on:



Any other hints would be appreciated.

Personally I would not expect debugger to work while it is disabled

Please check your php.ini one more time, from the top up to the bottom.
