Hi,
I'm afraid I need some help ;(

I have installed PHP-5.1 with Apache 2.2.3 on Centos5. It works fine.
I struggled with installing debugger but I finally managed to do this.

The phpinfo() reports followings:
This program makes use of the Zend Scripting Language Engine:
Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
with DBG v3.1.6, (C) 2000,2006, by Dmitri Dmitrienko

and:

The debugger section in php.ini has following content:
[debugger]
debugger.enabled = on
debugger.hosts_allow = localhost, 127.0.0.1, 192.168.32.11, 192.168.32.28
debugger.hosts_deny = all
debugger.ports = 10000/16, 7868

The project settings:
Run mode: HTTP mode (3rd party WEB server)
Root URL: http://mywebserver/

Debugger settings:
Use custom port and hots (checked)
Debugger port: 7869
Debugger host: clienthost
...


What is wrong?
Independently what I do, I am always getting following message:

Pop-up window:
Failed to start debug session.
Please verify if degugger module is installed on the server that corresponds to "httpd//192.168.32.28/accounts.php" URL


Content of the output:
DBG 3.1.6

Failed to run DBG session

Reason: failed to connect to the client address 192.168.32.11:7869
Not sure what it means? Visit http://www.nusphere.com/dbg/ for troubleshooting.

Debugger request: "392964324016100007@clienthost;d=1,p=0,c=1"
Request found in: "query_string"
Target PHP version: "5.1.4"
Server API: "Apache 2.0 Handler"
Extensions API: "220051025"
Modules API: "20050922"
PHP API: "20041225"

I tested "telnet 192.168.32.11 7869" from my server and it works pretty fine.

Moreover, when testing with analogical server platform (Contos4.4, apache-2.0, PHP-5.1) the debugger works well (all settings except URL in project settings are the same).

Is there any other way except phpinfo() and dbg-wizard.php to test that debugger is really installed?

please check if it's firewall affair and it blocks Apache process (it's httpd) from connecting to your client machine.

Hi dimitri,
thx for reply

both firewalls on windows (where phpEd is installed) and linux (server) are turned off

It means that debugger module tried to connect to 192.168.32.11 on TCP/7869 port and connection was refused.
please check that 192.168.32.11 is your workstation IP,
check that DbgListener is running and has its socket opened at 192.168.32.11 address (or 0.0.0.0) on 7869 port (netstat -naop will show all LISTENing sockets)
check that telnet running on the server can connect to 192.168.32.11 on 7869 port

Yes, this is a correct IP. I have checked output from ipconfig /all


I wrote it in my first post.
I am able to make connection using telnet from server to workstation.
The DBGlistener is reporting connection during such test so everything seems to be right.

then please check if httpd process is not allowed to make such connections. Can you try to connect from php?

I am not quite sure dmitri how to do that.

I was trying to use ssh2_connect function to make connection from php but it seems that this group of functions is not supported by my PHP version.
Do you know any simple way to test it?
Is there any command-line command that could be used to test apache access abilities from the server site?

thx dmitri

I finally fixed it. It was nothing wrong with debugger.
The culprit here was selinux that kept apache from opening port 7869.
After some changes the debugger works pretty well right now.

Just an additional tip, I had this problem and determined it was getting a permission denied due to SELinux being enabled. You can edit the /etc/selinux/config file to disable it.
