cURL problems

for timed 1: i use like this

<?php

$url = "http://www.hellboundhackers.com/challenges/timed/timed1/index.php;

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt($ch, [CENSORED]);
$result = curl_exec($ch);
curl_close($ch);

[some codes to get the base64 string]

$dec= base64_decode($base);
$url = "http://www.hellboundhackers.org/challenges/timed/timed1/index.php?b64=$dec";

header("Location: $url");
?>

the location i get is always url-decoded. so ` was interpreted as %60.

2. timed2, i code it and get "Malformed Request".

<?php

$url = "http://www.hellboundhackers.org/challenges/timed/timed2/index.php";
//$url = "http://localhost/timed2.htm";
$ch = curl_init();

[same curl declarations]

[some code to get sum, store it in $jmlh]

$url = "http://www.hellboundhackers.org/challenges/timed/timed2/index.php?check";
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "ans=" . $jmlh);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt($ch, CURLOPT_COOKIE, [CENSORED]);
$result = curl_exec($ch);
curl_close($ch);

echo $result;

Please use the code tags And also, try and make your problem abit clearer (Literally)

Hmmm, i can't say i know your problem though.. Sorry.

In timed2 you send wrong data in postfields they are usually a bit different from GET .
