Re: [Wifiadmin-users] PHP errors in debian

So, Sebastian gave me a user account to investigate this. I am posting
here, since more people might want to see this.
It is most probably a problem with your sudo configuration. It seems
that the user www-data can't run "sudo /sbin/iwconfig"
to see if this is the case, create a file called test.php in your
wifiadmin directory, with the following content:
<?php
include( "include/functions.php");
//this just runs iwconfig, and prints it's output, and the return code
print( system("sudo /sbin/iwconfig", $return_value));
echo("\n $return_value \n");
//the get_wireless_status function, parses the output of iwconfig,
and returns it in an array
print_r(get_wireless_status());
?>
then become www-data, by running:
su - www-data
and now try to execute the above script, running
php test.php
if you don't get the correct output (which is the ouput of iwconfig,
followed by a 0, followed by the pretty-print of the corresponding
array), check your /etc/sudoers file. Mine, looks like this:
# Cmnd alias specification
Cmnd_Alias WIFIADMIN = /sbin/iwconfig, /sbin/ifconfig,
/sbin/iwlist, /sbin/iwpriv, /sbin/route, /usr/bin/host, /usr/sbin/arp
# User privilege specification
root ALL=(ALL) ALL
www-data ALL=(ALL) NOPASSWD: WIFIADMIN
hope this helps.
