exec disabled, so how to call C++ .exe file?
|
|
| Greg Chapman 2005-06-05, 3:56 pm |
| Not sure if this is the right group for this but here goes anyway.
I am at my wit's end trying to get information out of Streamline.net's
support dept about my problem. They reply quickly enough, but seem to try
and give out the least possible amount of info each time. The transcript so
far is reproduced for your amusement below.
To summarise:
I've put up a Sudoku-solving program called Sudoku.exe. I want to call it in
a php script to solve a puzzle and output the solution. It works fine with
Apache/php on my own machine, but it seems Streamline.net disable exec,
passthru etc. They eventually say, cryptically: ' CGI executables are
supported, however this is very different from executing a program from
within a PHP script'. So how would I call my Sudoko.exe file?
Any help appreciated
Greg Chapman
The 'dialog':
My last question seems to have been 'fixed' before being answered, so I'll
have another go.
I'm trying to call an .exe file on the server but get an 'unable to fork'
error message. I have Apache/php installed locally and it works fine. Do you
have to turn on 'cmd.exe' permissions or something? Try it yourself at:
http://www.ramseyarts.co.uk/sudoku.shtml
Warning: passthru(): Unable to fork [Sudoku.exe (argument...)] in (.php
file...)
It's the same with exec() as well.

Greg Chapman
Hi Greg,
Thanks for your query.
We do not support passthru or exec functions.

So how would I call my Sudoku.exe program from a php script?
Hi Greg,
Thanks for your query.
Unfortunately we do not provide scripting help, we suggest searching on
google for scripting help sites.

I do not want 'scripting help', I just want to use some of the functions
that you offer as a host and which I have paid for.
As I have said what I am trying to do works perfectly on my machine, so it
must be a question of something you have to enable your end. What do you
mean you don't support passthru or exec? They are both standard php
commands.
Please read my questions properly and do me the courtesy of giving a proper,
non-automatic reply.

Hi Greg,
Thanks for your query.
You asked "how would I call my Sudoku.exe program from a php script?"
clearly this is asking us how you can use scripting?
Certain functions are disabled in PHP for security reasons.

Which functions are 'disabled in PHP for security reasons' ?
Hi Greg,
Thanks for your query.
You can find this out with the inbuilt php function phpinfo()
Kind Regards,

Could you tell me where on the page that phpinfo() produces these functions
are listed? For example, passthru() does not appear to be on the page.
Hi Greg,
Thanks for your query.
search for "disable_functions" on that page.
Kind Regards,
StreamlineNet
Streamline.Net - The home of good value web hosting
disable_functions lists 'no value'. So again, could you tell me where I can
find the list of standard php functions which you have disabled?
Hi Greg,
Thanks for your query.
Please can you provide a link to your phpinfo file so we can investigate
this further.
Kind Regards,
StreamlineNet

The link is:
http://www.ramseyarts.co.uk/info.php
Thanks for your query.
We had previously checked this on a linux server, which showed the functions
that have been disabled. We've passed this on to an engineer to investigate
further.
For your information the following are disabled:
shell_exec,exec,system,passthru,popen
Kind Regards,
StreamlineNet

Your knowledge base says:
Q. Are CGI (Common Gateway Interface) executables supported?
A. Yes these are supported on either the Windows and Linux servers
But you are telling me that the only php functions which can call my
executable are disabled. Will you clarify once and for all if I can call my
exe file or not. I AM NOT ASKING FOR SCRIPTING HELP, I have books about
that. I just want to know if I can do ON YOUR SERVER what you say I can do,
and if not why not.
Hi Greg,
Thanks for your query.
CGI executables are supported, however this is very different from executing
a program from within a PHP script.

With your current ISP's configuration, you are not able to call external
programs like Sudoku.exe from a php program. Their configuration won't
allow it. If they're unwilling to change their configuration to offer
you shell_exec, exec, system, passthru, or popen functions, you have two
options:
(1) write a perl script which calls system('Sudoku.exe').
(2) find another ISP that offers services that better suit your needs
(you may end up getting a dedicated Linux system that you'll have to
configure and administer yourself)
If you can't code in perl or it turns out they've disabled the system()
function in perl, you really only have option (2) available to you.
Good luck.

| Thanks Michael
Part of the problem was I got into php before doing any basic cgi stuff.
I wish support at Streamline were half as helpful.
I'm now calling my program outside of php and it works fine:
http://www.ramseyarts.co.uk/sudoku.shtml
(Actually it's a crap program and only works on easy puzzles...)
