exec function

[shyma]

i know that exec function in php used to execute commands , i have a problem:i try to use exec function to execute iptables command but i failed.please help me.
this is the code
<?php
$output = shell_exec('iptables -L ');
echo "<pre>$output</pre>";
?>

<?php
$output = shell_exec('iptables -L ');
echo "<pre>$output</pre>";
?>

your code is working from command line.
If you are trying execute this code using browser then check with absolute path name

replace this line

$output = shell_exec('iptables -L ');

with this

$output = shell_exec('/sbin/iptables -L ');

Let me know the results

<?php
$output = shell_exec('/sbin/iptables -L');
echo "<pre>$output</pre>";
?>

Are you trying to run php from web browser?
anyway first check that code runs from command line or not.
if it's not running from command line post it's output as well as post the output of command
whereis iptables

[shyma]

thanks.

You are logged in as root -- right? and
you are getting desired output from command line-right?
And you are not getting result from browser - right?

Then try and replace the command iptables with simple command like ls

/bin/ls

If 'ls' command gives you output then i think problem lies with permissions.

Try with ls command and let me know the results

[shyma]

simple commands can be executed. and iptables commands can not.
how i can get permissions to execute iptables commands through php interface?
please help me.

So root user commands are not executed.
If i'm not wrong - i think you need to give permission in /etc/sudoers -you can give sudo privileges to apache's user, and then use it on php [also check out httpd.conf if ur server is apache & php.ini ]

Try google from here on about "executing root commands under php using browser"

All the best
