[RESOLVED] exec or shell_exec or anything that will sovle the problem, help!

buggin

Someone please stop me from throwing my computer.

I am coming up on 20 hours trying to solve this problem. I have read many post that gave me lots of good ideas. but I cant seem to make any of them work for me.

Background:
OS: ubuntu 7.1
Apache2
PHP5

::High level objective::
I want to execute a vb script via php.
The script finds a data file in the same directory and processes the data into another file in the same DIR.

::What I have gotten to work::
I can use wine in the terminal to successfully run the script.

I then created a super simple bash script so that apache will only have to have permission to run the script file. The script works when I double click on it and select run from the options provided. Sound good?

#!/bin/bash
cd /var/www/processed
wine /var/www/processed/extractor.exe

which leads to:
::Question 1::
How do I make absolutely sure that apache has enough permissions to execute the script?

I am using the script because I dont know if apache2 has permission to use wine.

::Question 2::
How do I execute the code in PHP?

What does not work:

shell_exec('callscript');
shell_exec('extractor.exe');

shell_exec('ls -l'); lists the extractor with the appropriate executable permissions.
shell_exec('PWD'); shows the correct current directory
shell_exec('whoami'); Returns www-data

::Question 3::
I took a look at the apache error log and found that when wine is call directly from PHP I get:

[Thu Nov 15 09:16:19 2007] [error] [client 192.168.1.1] File does not exist: /var/www/favicon.ico
wine: can't get temp file name for /var/www/.wine : Permission denied

When I call the script I get:

[Thu Nov 15 12:09:54 2007] [error] [client 192.168.1.1] Could not fetch resource information.  [301, #0]
[Thu Nov 15 12:09:54 2007] [error] [client 192.168.1.1] (2)No such file or directory: Requests for a collection must have a trailing slash on the URI.  [301, #0]

OR

[Thu Nov 15 12:14:24 2007] [error] [client 192.168.1.1] Could not fetch resource information.  [403, #0]
[Thu Nov 15 12:14:24 2007] [error] [client 192.168.1.1] (2)No such file or directory: The URI does not contain the name of a repository.  [403, #190001]

I am also getting an error every time the page is accessed. It maybe unrelated but I don't know how to get rid of it or where it is coming from.

 sh: callscript: not found
[Thu Nov 15 11:37:26 2007] [error] [client 192.168.1.1] File does not exist: /var/www/favicon.ico

I never wanted to have a favicon and I dont know where the request is coming from. I checked the apache2.conf and httpd there is nothing there.

Please Help,
Thanks

Is this an executeable or a .vbs script?

I'm not sure, but if it's a .vbs script, I believe the problem is that apache does not know what to do with a program with a vbs extension.

If it is the "extractor.exe" program itself, what are it's flags? 755? Recheck your ownership permissions. Does apache or its group own the file?

It could be a lot of things, other than PHP here...

buggin

The Bash script calls the executable file.

www-data is the owner of the .exe and the bash script

and the flags are set to 0755 for both the .exe and bash script.

I realize that this problem probably has more to do with the OS than PHP.

But I hope that someone will be willing to offer some ideas.

Try setting ownership to apache, first. If your apache user and group are both apache (a common setup) then use chown to change the ownership of the program and the script to apache, like thus:

chown apache:apache executeable.exe (or whatever it is)

Do this for both the executeable and the script. Hopefully this will help.

buggin

In the Apache config file the user is www-data and the group is www-data so I think that I am ok there.

I am still getting the following errors in the error log

[Thu Nov 15 14:10:32 2007] [error] [client 192.168.1.1] File does not exist: /var/www/favicon.ico
[Thu Nov 15 14:10:33 2007] [error] [client 192.168.1.1] File does not exist: /var/www/favicon.ico
sh: callscript: not found
[Thu Nov 15 14:10:34 2007] [error] [client 192.168.1.1] File does not exist: /var/www/favicon.ico
[Thu Nov 15 14:10:34 2007] [error] [client 192.168.1.1] File does not exist: /var/www/favicon.ico

callscript is the name of the script but it is not located in the root directory

let me try a symlink

Turns out wine needed access to a temp file in the owner directory. Liking the .wine temp folder and changing the permissions to allow the apache user to be the owner allowed wine to run and process the file.

Thanks.
