Exec Wont Run A Cpp Program


I'm trying to get Zonminder up and running on FC4 One of the asso programs is zmu.cpp - compiles fine. And runs from the command line IE. /u/l/b/zmu -help returns Usage. zmu -m 2 -z (real cmd) from cmd line does what it should do. However (in xx.php) exec ("/usr/local/bin/zmu -m 2 -z", $ret); doesn't.

From what I can tell it doesn't even enter the program. Permissions are 755. If I change the exec to ("ls") - works, date - works. I've compared "env" - nada. SafeMode = Off. Is there ?anything? else that might cause my problem?

PHP Running Exec() Windows Program Very Slow In Comparison To UNIX Equivalent Program
Does anyone have an explanation or solution for the following.
I have a PHP script that uses exec() to call a program to do certain
calculations.

The UNIX version of this program I call runs in about 4 to 5 seconds.
When I run the same PHP script using exec() to call the Windows equivalent
of this same program on my Windows desktop, it takes about 32 seconds....

Cannot Get The Program To Run At All Through Exec
I downloaded the program called Snapshotter which allows you to take screenshots of webpages through the command-line. Server is Win2k3/XP (live/local). I cannot get the program to run at all through exec

while the same directory/permissions for ffmpeg run fine. I cannot even get it to spit out the default output you get if you run it without arguments. exec("dir") works fine, but exec("c:lahSnapshotter") doesnt return anything. Registered the path in the PATH environment and still no luck, yet exec("c:lahffmpeg") works fine and returns data.

Exec A Commandline Program

Exec() Call To External Program
We are trying to use the exec() or system() calls in a php script. The program we are trying to call takes 1 parameter in the form of: email@domain.com[usercode]

There are no spaces in the parameter at all and we have tried placing quotes around just to see if it mattered. We have also modified the parameter just to send it hello. Here is what we get: With no parameters the php script executes the program where it displays the error message from the program stating that not enough parameters were supplied. We then add the word "hello" to the end after a space so the command looks like this: command "hello" and the program no longer executes at all. No matter what we do, if we supply an argument to the command the php code will not execute the program.

Php Exec To C Program That Writes File
I'm trying to use the exec() call in php to run a program that I've
written and compiled from C. This program attempts to create a new
file and write data into it.

If I simply run the program from the shell, it writes the file no
problem. If i run the program through an exec call in a php script,
however, the program executes but it seems to not have the correct
permissions to be able to write the file.

Use Exec To Run The Program Directly From The Server.
I have an image manipulation program that is run from commandline, I have never used exec before and I'm scared to becuase I don't want to mess up my server or anything.  Basically, I want people to be able to upload an image, then arrange for some manipulations to take place on the file in a temporary batch file, then use exec to run the program directly from the server.  The program is called nconvert.exe, and the main thing I want to do is convert DDS textures into BMP files, the command, from Windows "cmd" is:

nconvert -out bmp %1
%1 being the dds file to be manipulated.

How would I go about doing the exec part?  I know how to do the upload, but not the exec.

Securing Data Between PHP Script And Exec'd Compiled 'C' Program
I'm using RSA Securid Tokens, and I'm going to write a little 'C' program that takes as input the userid (i.e. "jsmith") and the number displayed on the token (i.e. "123456") and returns a result code indicating whether authentication is successful.

The compiled 'C' program will be called from a PHP script.

I know that if I pass the parameters on the command line, i.e.

authenticator jsmith 123456

the parameters are world-visible (via "ps -Af", for example) and this is an
information leak.

<BEGIN QUESTION>
How can I pass things securely between the PHP script and the exec'd program?
<END QUESTION>

One way I suppose I could always use is to create a file from the PHP script and then just pass the filename to the program (assuming permissions and UID/GID were all set up correctly).

But is there a more elegant way that doesn't create files, such as pipes or shared memory?

How To Program OOP
I use OOP for a PHP Application Framework I am programming. I have one base class which includes all the necessary functions and variables which all the other classes use. So what I originally did was that I made an instance of the base class and passed it to the other classes. Now someone insisted that this is not the way to do it.

so I used 'extends base' to make the base class available to the other classes. Afterwards it worked fine, but it didn't make the code smaller nor did it result in faster speed. I used the benchmarking script from PEAR. So I wonder whats the difference between those two solutions, both work fine. Are there some tools to analyse how much memory a script uses?

Using Exec()
I'm trying to use the exec() function to call shell scripts that in turn startup various programs under linux.. for example, when someone clicks on a link to restart a particular daemon, the daemon will then simply executed, either through the standalone command of /location/daemon or through the calling of a shell script that essentially performs an identical task.

My problem is that exec() seems to only work through the user "nobody," which the Apache web server is running under. The scripts and programs I'd like to execute are under a user account named "admin."

I've even tried chmod'ing all pertinent files w/ permissions that "nobody" could use to successfully access all necessary commands, without success, as the programs seem to crash whenever I do this.

PHP And Exec(dir)
I have been using opendir and scandir, but I want to try something
else.
Idea: using dir, and a) getting the result b) saving it as a file.

As I have problems with executing files directly, it create a bat file
and executes that.
I can execute command, but by some reason I dont get any response (it
should return something, and I get "")
The missing response is why I create a file.

I create the file on the network ( serversomewhere ) like this

dir "serversomewherefilesdir" >"serversomewhere
esult.txt"

Here is the odd thing: dir cannot read from the network - the bat file
is created there, it creates the result.txt file, but emtpy as it
cannot read from the network. Reading from c: and it works.

Should I Use A One Php Program Or Multiple
I have taken over a php web site. Once you login you are given six menu
choices. Each option is or can be independant of the others. They each
modify the same database but in different ways.

On clicking the menu buttons the program calls php functions to do the
action. Thus the user stays inside a large program.

I was expecting the menu to provide links rather than function calls.
1) Is there a reason to stay inside a large program through function
calls rather than linking to separate pages?

2) Am I correct that providing a <a href=... link would isolate the
functionality and call a new program?

The current program is spagettii code and somewhat buggy. There are
side effects that depend on what function was called before. I am
hoping that passing the hidden input parameters is all the connectivity
I need.

Program Flow
I had some bad experience with code organization and script
functionality in writing my php based applications. And as the applications

What I have now is one script that resolves the operation to be done
according to the parameters send to it and the call the processing unit to
do the rest of the job. However, as I add more functionality to the system
this dispatcher script gets bigger and bigger...

maintainable way?

completely seperate from the others (I have lots of forms and outputs I have
to show the user when necessary)?
