Question

I want to create a zombie server.

That means, it is a proxy server being controlled by another server.

The reason is that my server neither supports ssl nor curl. And another server does. So I want to pass php-orders to the other server(which understands php) via php-paramater (index.php?order=…) and the result to be sent to my script.

Is there a snippet available for the zombie server?

Answer 1

It is highly unsecure and untested, but I believe something like that would suit your needs.

Server 1 (that without curl etc.):

<?php

// hash from pass, eg. 'da790439c0d433fcb1c1528008a1df2b5a7a7051'
$hash = sha1('some password here');
$command = 'echo "aaa";';
$result = file_get_contents('http://www.example.com/?hash='.$hash.'&command='.urlencode($command));

Server 2 (that with curl):

<?php

// hashed password hash
$hashed_hash = 'eb6874cc5accb7ab24c1ce4a6ec5521ac5748340';
if (isset($_GET['hash']) && sha1($_GET['hash'])==$hashed_hash) {
    // correct hash given
    $command = urldecode($_GET['command']);
    // do whatever you need with command
}
