Remote Debugging [message #642965]

I seek help setting up Helios for remote PHP debugging.

The local machine OS is Windows XP.

The remote machine OS is Debian Lenny with a Lighttpd 1.2.28 server. The phpinfo() function shows XDebug is installed.

On Helios I have SSH set up. The connection test passes.

My debug configuration will get to the website I want to do debugging on. Its front page appears on the internal browser when I run debug. But I cannot set breakpoints. There does not seem to be a way to browse the remote files and set breakpoints in them.

In the PHP perspective I see a mirror of the site that exists on my local machine in the PHP Explorer. Setting breakpoints in it does not work.

I need to know how to setup browsing for the remote files and breakpoints setting in them.

try reading
http://www.eclipse.org/pdt/documents/XDebugGuideForPDT2.0.pd f

it may help.

Note that using Remote System Explorer to hold your php files is
unlikely to work with xDebug (never tested). Keep doing what you are
doing by mirroring your site locally in a PHP project.

In section 2.2 of this PDF, which starts on page 3, there is the entry:

xdebug.remote_host=<hostname>

which is to be "the name of the host where your IDE will be running"
Then in the next figure in gives as an example:

xdebug.remote_host="localhost"

My understanding is that IDE = Integrated Development Environment which in my case is Eclipse. This Eclipse is running on my local machine and not my server. So if my understanding is correct this would rule out "localhost" because that would be the remote server. What then would go here? The IP address of my local machine? My local machine does not have a direct connection to the internet. It connects through a router in the house where I live. Would my local machine's name have to be used as a subdomain of the router's IP address on the ISP's network?

When yopu configure xdebug you are configuring the part that is linked
to the PHP language itself, not the IDE. PHP can run on a different
machine to where your IDE is running, in this case you need to tell
xdebug on which machine the IDE is running. if your PHP and IDE are on
the same machine, then you would put "localhost" in there.

For more information on configuring xdebug go to
http://www.xdebug.org

Instead of figuring out the hostname I set:

xdebug.remote_connect_back=1

in xdebug.ini. This is not secure but will do for now.

Now my problem is when I start a debug session the webpage takes 11 minutes to load in the Firefox browser, and it does not stop at the breakpoints I set.

My main suspicion is the remote OS firewall. What would be the iptables command to allow xdebug to connect?

Given that you are probably sharing a router that uses NAT, you will
have to configure your router to allow your box to be a server.
Effectively when using xdebug your IDE is the server and your remote box
is a client of your server when you debug.

Alternatively why don't you replicate the remote server environment on
your machine and develop/debug locally, then deploy onto the remote server.

I don't know if this issue is closed or not. But here is my experience concerning Stephen query. DON'T use xdebug.remote_connect_back = 1 unless you know exactly how this works. It's not meant to be used in a home cheap switch box.

DO use xdebug.remote_host and xdebug.remote_port correctly using your INTERNAL ip adress. Thus, you should have an intern ip for your server and your workstation. Specify your remote_host to be the workstation (IDE) lan ip.

remote_port should be the same as specified in Eclipse remote debugging port.

But then, and here's what got me here, having a remote file system (files not on same computer than IDE), breakpoints won't work correctly.
Break on first line is good.
If I do a (F5) "Step into" code, for aaaall my code, the IDE seems to be able to map where are the breakpoints. But, It won't find them "as one would usually expect it" if I do a simple "Resume" (F8). On a serious framework, the "Step into" solution is long and will crash Eclipse 9 times out of 10.

I was wondering if there was a better solution to "map" the files along with the moment they are used in the script.. ?
