PHP :: Exec(), System() And Win 2003

Bug In System And Exec Commands
If PHP is running via a web server, and mutiple system
calls are made within the script to another script,
hundreds of processes are created. Here is an example:

Script 1:
<?php
for ($i=1; $i<=5; $i++) {
system("php script2.php");
}
?>

Script 2:
<?php
exit;
?>

The effect is the same (and more difficult to stop) when
the system calls are made in the background. e.g.

system("php script2.php >>/dev/null 2>>/dev/null &");
system("php script2.php >/dev/null 2>&1");

I have even tried calling a shell script, which in turn
calls the second PHP script (both in the background), but
it still causes lots of processes.

The "exec" command is also affected.

At first, I thought this was a problem with either Zeus web
server of Fast CGI, but I have since tried it with Apache
and normal CGI with the same effect.

Does anyone have any idea why this happens and whether there is any way to prevent it? I have posted a bug report to bugs.php.net (ID 14997), but so far to no avail.

Exec() And System() Problems
I am trying to use php's exec() or system() to execute a shell script that I wrote.

exec and system() work fine with a simple command like ls, but nothing happens when I point it at the shell script.

The shell script works fine from my shell login. Can't figure out what tho problem is. Is php just incapable of running shell scripts?

System/shell/exec/etc
I've got PHP 5.1.6, Apache 2.2.2, on Fedora 5. Everything is great except that when I use an of the external launching commands, persistent apps dont stay open. I have a simple shell script set up to load an app, and I have it write a PID file. Immediately after calling exec (milliseconds later) the PID is alive. However, within a few more milliseconds it seems to close.

I've made sure that the apache uid/gid have full access to the script and the apps it calls. When sudo'ing manualy in a shell with the apache uid, the script works flawlessly and loads the program, and stays open, as it should. I've verified that the app loads under the uid 'apache' with ps. When running it through PHP, it seems to close almost immediately after succeeding.

Is there some fundamental issue with how this works that I'm missing? I can't seem to get any real errors out of php, apache, or even the shell when redirected to a file. Should I try PHP4? Is PHP5 buggy with this kind of thing? I even tried running 'at' to schedule the script (so that it'd be invoked by at instead of the shell itself) but that failed, silently, as well.

Use Exec() In PHP 5.2 On A Windows XP Pro System
I'm trying to use exec() in PHP 5.2 on a Windows XP Pro system. What I'm trying to do is use it to tell an already running program what to.

For example:
X:pathprogram.exe /something
or
X:pathprogram.exe /something_else

If I do the command through the command line, it works, but so far I have been unsuccessful in PHP. Usually it PHP just hangs, and give no error message, and does nothing to the program.

Using System/exec, How To Backup Database?
system("mysqldump --opt myDatabase > backup.sql");

here are my problems,

i don't think it works on the webserver. next, where exactly the file, backup.sql be place if it does succeed.

i believe we just can't execute commands on the webserver can we?

i also tried using the sql query BACKUP TABLE ... TO .. but i'm guessing the problem lies with the TO... how do i know what directory shall i place it therE?

for instance, my pages are placed in,

home/myname/public_html/...

i tried to put
home/myname/public_html/backup in the TO but nothing happens.

Exec(), System(), Shell_exec(), Etc + Nmap
i'm trying to create a script that executes nmap from my server, then displays the output.

i've tried:

$output = passthru('nmap -v -A'.' $ip');
$output = shell_exec('nmap -v -A'.' $ip');
system('nmap -v -A'.' $ip');

the problem i'm having is that using the above methods i only get the first line of output, ie.

Starting Nmap 4.20 ( http://insecure.org ) at 2007-08-31 21:46 CST

and nothing else. i've managed to find a way around it by sending the nmap output to a textfile, the using file_get_contents() to pull the data back in:

exec('nmap -v -A '.$ip.' > /usr/local/www/apache22/data/nmap/'.$ip.'.html');
$file = "/usr/local/www/apache22/data/nmap/$ip.html";
$result = file_get_contents($file);
echo "(pre)$result(/pre)";

that works perfectly, but i'd rather not be writing anything to the drive. i guess the problem might be that nmap takes about 5-10 seconds to do its scan, and for some reason php doesn't want to wait that long, i really have no idea. can it be made to work without needing to write to files?

and for the curious minds, i'm not doing anything dodgy, i just wanted an online tool i could access from any computer to test networks i support .

Command Window - Exec/system
I'm in the process of developing a script in Windows where I need to use exec/system. Whenever I execute either, Windows spawns a command window which automatically sappears. Is there a clean way to force Windows to NOT display the command window?

I've seen this discussed a few times previously, but, none of the
solutions seem to be working (tried both exec and system; tried using
cmd /c, tried using start /B, etc.)

Exec And System Commands Blocked By Host
I've got this code, its the simpliest example I could make. It works perfectly on my windows xp/apache/php box, but doesn't do anything on a commercial website host. The actual code should use gzip to compress a folder but that doesn't work either.

Anyone know the reason why they would be blocking these commands? I suspect the problems with commonly used php apps like phpBB to be the real reason.

<?
exec("ping 127.0.0.1 > test.txt") or die();
// get contents of a file into a string
$filename = "test.txt";
$fd = fopen ($filename, "r");
$contents = fread ($fd, filesize ($filename));

fclose ($fd);

echo $contents;

Alternates To System() And Exec() In Order To Use ImageMagik?
My Web host apepars to not allow exec() and system(), as a line in my script:

system("convert -scale 100x100 $uploadfile $toimage");

"Warning: system() has been disabled for security reasons"

Is there some other way to use ImageMagik (or is it GhostScript?)'s

Mail() And Exchange 2003
I work for a small college in Virginia and we were running Imail up until December. During the Christmas break we migrated to Exchange 2003 and we are running GFI Mail Security and GFI Mail Essentials and it is running on a Server 2003 box. We have all of our web applications housed on a Red Hat 9 box.

Since students have came back and started using our applications, we've noticed the mail() function is no longer sending mail. It doesn't seem to give us an error or anything. Just doesn't pass mail to our users even if they use an outside email address such as Hotmail or Yahoo.

I looked around and found out that Exchange doesn't have some of the functionality with SMTP and other Internet protocols so is there a way I can get my email forms to work again?

IPv6 Summit 2003
I would like to invite you and your associates to attend the US IPv6
(Internet Protocol version 6) Summit, December 8-11, 2003 in Crystal City,
VA, near the Pentagon. This major opportunity to participate in
transitioning to the new Internet is in response to both DoD and Industry
requests for a concentrated, affordable conference in the Washington, D.C.
area.

This exciting and informative conference on the Next Generation Internet
will attract a remarkable line-up of speakers, including major executives
from the Department of Defense and Industry, as well as prominent global
scientists and analysts. This gathering should offer your organization great
opportunities for forming new strategic relationships. Revenues from new
products and services arising from the Next Generation Internet have been
estimated at a trillion dollars over the next decade.

You have undoubtedly heard of the booming interest in the new Internet,
because of its dramatic improvements in end-to-end security, peer-to-peer
communication, support of new generations of Internet-enabled consumer
electronics and defense systems, and wireless mobility capabilities, as well
as the recent announcement by the U.S. Department of Defense (that it was
switching all Internet operations over to this new standard beginning in
October 2003) and support by major vendors such as Microsoft and Sony. The
Department of Commerce recently created a Task Force to generate an IPv6
roadmap. The press has also reported on the enthusiastic support for IPv6 by
European and Asian governments, which have already started replacing the
present Internet Protocol (in use since 1973). Sponsors for the Summit
include IBM, Cisco, Sun Microsystems, Verio/NTT, HP, Nortel, Spirent,
Automation Research, Elmic, Cal-(IT)2, IP Infusion, Alcatel, INS, Extreme
Networks, Foundry Networks, UNH-IOL, Internet2, Nokia, KMI, Ixia, IPv6
Promotional Council, and the Northern Virginia Technology Council. Everyone
who wants to benefit from early adoption of the new generation Internet will
be at this conference in order to assess and to influence the 21st Century
Internet. You should be there, too.

We would sincerely appreciate it if you could put these dates on your
calendar. You can read a more complete description of the Summit and
register at http://www.usipv6.com. In addition to the presentations on
December 9-11, there is also an optional comprehensive IPv6 tutorial on the
8th - please register NOW, because space is limited (and early registration
saves you up to 50%). If you live outside the D.C. area, you'll want to
reserve a room at the Doubletree Hotel as soon as possible, to be assured of
conference rates.

I will be happy to discuss our conference and to answer any of your
questions at (310) 458-3233 -- or you can send an email to our dedicated
information desk at info@usipv6.com. We hope you can attend and join us. We
thank you in advance for your support -- and for forwarding this invitation
to other individuals and companies who might want to attend the U.S. IPv6

Php On Windows Server 2003
I work on a site with a friend of mine. Recently he transferred the site from being hosted on a Unix server to being hosted on his own server running Windows Advance Server 2003. He seems to know about as much about setting up servers as I do (which isn't much!), and although he's gotten PHP running, none of my PHP scripts that write files work. I've looked up answers and he's tried different things, but so far he hasn't been able to resolve the problem. Without being able to use fwrite() I will have to update several areas of the site by hand.

Here's a sample error:

Warning: fopen(file.txt): failed to open stream: Permission denied in G:modelsonline estswrite.php on line 11

Warning: fwrite(): supplied argument is not a valid stream resource in G:modelsonline estswrite.php on line 12

Warning: fclose(): supplied argument is not a valid stream resource in G:modelsonline estswrite.php on line 13

Can someone give me the dummies version of how to resolve this so I can explain it to him?
