Ping not running

[checked]

I am on Redhat 9 and Safe Mode is off. I checked a ping program but it is not showing any result. I have tried so many commands to run the ping from PHP it does not show any result.

<?php
echo 'Ping : ';

// It is showing RESULTS
$last_line = system('ls -la');    

// Not showing anything
//$last_line = system('ping -c 5 google.com', $retval);    

// Not showing anything
//$last_line = passthru("ping -c 5 google.com", $retval);
//echo $last_line. "  ". $retval;

// Not showing anything
//$a = shell_exec("ping -c 5 google.com");

// Not showing anything
$a = shell_exec('ping');


// It is created folder successfully
echo mkdir("/home/frmwhev4/www/abc/Folder");

echo "folder created";
?>

When I tried to run system('ls -la'); command it shows the result but when I place the command system('ping'); it does not show any result whereas it should show some output.

Note: I am able to run ping from SSH but not able to run from PHP. Below are the ping Permissions

-rwsr-xr-x 1 root bin 28628 Jan 24 2003 ping*


Can anyone know the problem !

Do you have open_basedir protection enabled? WHM > Tweak Security > php open_basedir Tweak

If you do, then you cannot access binaries outside of your account tree. What you might be able to do is create a symlink to it in your account via ssh and then use that. So, SSH in and:

cd /home/account/
ln -s /bin/ping

Then in your script use /home/account/ping instead of just ping - might work
