1. Sorry for my english
2. I have read http://forum.nusphere.com/howto-install-debugger-module-t576.html ( its like to "Configuring 3rd party WEB server" from PhpED manual )
3. I have
FreeBSD 4.10
apache 1.3.33
PHP 4.3.10

Apache works in chroot : /var/chroot/apache_1.3.33

I get phpEd 3.3.3evl and install it on my win computer.
I take dbg.so-4.3.10 from debugger\server\FreeBSD\dbg-2.16.16-FreeBSD-4.10.tar.gz ( from dir i386 ) and put it to /var/chroot/apache_1.3.33/var/php/extension

Edit php.ini ( in my chroot ) :
extension_dir = "/var/php/extension"

extension=dbg.so-4.3.10

[debugger]

debugger.enabled=on
debugger.profiler_enabled=on
debugger.hosts_allow=192.168.4.5
debugger.hosts_deny=ALL
debugger.ports=7869, 10000/16

192.168.4.5 - my comp with phpEd

Reload Apache and see phpifo() : don't see string like "DBG v2.16, (C) 2000,2004, by Dmitri Dmitrienko"

I insert next strings to my php script:

if( dl('dbg.so-4.3.10') ) echo "load dbg.so-4.3.10 <br>\n";
else echo "not load dbg.so-4.3.10 <br>\n";

and try again and have seen message about bad "libwrap.so.3" and "not load dbg.so-4.3.10"

I copy libwrap.so.3 to my chroot and try again and see message "load dbg.so-4.3.10"

But I could not see string about "DBG v2.16, (C) 2000,2004, by Dmitri Dmitrienko"

In apache error_log:
[Thu Mar 3 15:39:11 2005] [notice] Apache/1.3.33 (Unix) PHP/4.3.10 mod_ssl/2.8.22 OpenSSL/0.9.7e configured -- resuming normal operations
[Thu Mar 3 15:39:11 2005] [notice] Accept mutex: flock (Default: flock)

I have no any string like "zend_extension" in php.ini.
What i have to do to install DBG ?

login via chrooted user account or somehow else check dependencies for dbg.so modue by running ldd (verbose mode) under chrooted account.
Then make sure libwrap is installed correctly and chrooted /etc/ contains hosts.allow and hosts.deny

I have made:
cat /etc/hosts.allow

and have seen :
.......
NOTE: The hosts.deny file is deprecated
.......

There for i have copied only /etc/hosts.allow to my chroot and restarted apache. After that i have seen string : "with DBG v2.16.16, (C) 2000,2004, by Dmitri Dmitrienko" on page with phpinfo().

Thank you. Now i shall try to use remote gebugging.
