Permission denied when running scripts from php

Hi!

I have some problems.
I'm kind of n00b, so hope you can help!

I have a Fedora server with Apache and PHP.
But I get a permission denied when I'm running a script from the webbrowser.
Here is my PHP code:

Code:

function execute($command) { 
    $command .= ' 2>&1'; 
    $handle = popen($command, 'r'); 
    $log = ''; 
    while (!feof($handle)) { 
        $line = fread($handle, 1024); 
        $log .= $line; 
    } 
    pclose($handle); 
    return $log; 
} 

echo execute("wakeonlan 00:04:61:6B:A4:71");

Output: socket : Permission denied at /usr/bin/wakeonlan line 78.

What permissions do I have to set? Thanks

 

What's the output of

Code:

ls -l /usr/bin/wakeonlan

?

 

[root@localhost ~]# ls -l /usr/bin/wakeonlan
-r-xr-xr-x 1 root root 5318 okt 27 01:41 /usr/bin/wakeonlan

 

What happens if you run

Code:

chmod 777 /usr/bin/wakeonlan

?

 

Greetings,

I am having a similar problem. I've created a script that reads a template file then creates and posts the template into a new file using fopen but it returns with "fopen(/usr/web/bsu/test.php): failed to open stream: Permission denied in /usr/web/bsu/admin/includes/functions/content.php on line 134"

I've double checked the /usr/web/bsu directory and it's permissions are set to 777.
Are there any other permissions that need to be set for this kind of action?

 

Hope this is of some use, if you want to change permissions for the entire folder and its contents, you would do this

Code:

chmod 777 /directory name -R

otherwise just do

Code:

chmod 777 /directory/file.php

Your permissions may differ, 777 was only for an example

 

Also make sure you disabled PHP Safe Mode.

 

The folder and files are already 777 and PHP safe mode is disabled.
I've even gone so far as to try chown on the directory to apache to see if the PHP group needed permission but still didn't work

 

Finally got it. For those with a similar problem. Check SELinux enforcing parameters.

/etc/selinux/config
