PHP - Proxy Script
Could someone give me a cross-domain proxy script?
I am trying to post data to mysql databases on two servers. Similar TutorialsHi guys, I am creating a script as I am using this to detection the proxy server levels. <?php //proxy levels //Level 3 Elite Proxy, connection looks like a regular client //Level 2 Anonymous Proxy, no ip is forworded but target site could still tell it's a proxy //Level 1 Transparent Proxy, ip is forworded and target site would be able to tell it's a proxy if(!$_SERVER['HTTP_X_FORWARDED_FOR'] && !$_SERVER['HTTP_VIA'] && !$_SERVER['HTTP_PROXY_CONNECTION']){ echo '3'; } elseif(!$_SERVER['HTTP_X_FORWARDED_FOR']){ echo '2'; } else echo '1'; ?> I want the script to check the ip that if the proxy server is a Codeen/PlanetLab and BotNet proxy servers, then place on level one and if they are safe/unsafe to use. I cannot find the code to do the methods. Please help me! Thanks in advance. Hi guys, Before I am going to create php script to make a proxy detection, I want to ask that if it possible to create a method that checking whether if the proxy server is a located governments or fbi. Is it possible? If so, what method I would use? Thanks, Mark Hi I need a script to hide IP address with proxy and read a web page
$username="myuser"; The script doesn't work, it doesn't show me the page output. Any solution? using curl, ive managed to get my program to log me into a proboards site. I can view the main forum page. The problem is, the links to viewing the page is something like href="index.cgi?board=general&thread=1111&page=45" I did a str_replace to replace the index.cgi to href= "link_processor?board=general&thread=1111&page=45" The idea was that link_processor would contain the data "board=general&thread=1111&page=45" However, i now realise that the way the php would see that as 4 different get variables link processor = board=general thread = 1111 page = 45 How could i make it all part of the link_processor variable because if i can keep the string intact, i just have to pass it to a curl function and i can display the page easily! I need a proxy that would enable me to use curl with another ip address. How do I find a paid proxy server that supports curl? I have this PHP script to fetch whois information of domain. It works, but when I try to connect whois server via proxy, then it doesnt work. The proxy ip is taken from proxylist.hidemyass.com. What I do wrong? Thank you for help.
$server = "whois.nic.cz";
$domain = "klikzone.cz";
function QueryWhoisServer($server, $domain){
$proxy = "85.111.25.189:8080";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $server);
curl_setopt($ch, CURLOPT_PORT, 43);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $domain . "\r\n");
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
Hi, I'm trying to understand any how I can block all users trying to view my website through proxies. With the following code, what I have done is a quick version through php (with headers and ports) and not the firewall which isn't exactly the best way but still stops a lot of them.
<?php
$user_ip = $_SERVER['REMOTE_ADDR'];
$headers = array('CLIENT_IP','FORWARDED','FORWARDED_FOR','FORWARDED_FOR_IP','VIA','X_FORWARDED','X_FORWARDED_FOR','HTTP_CLIENT_IP','HTTP_FORWARDED','HTTP_FORWARDED_FOR','HTTP_FORWARDED_FOR_IP','HTTP_PROXY_CONNECTION','HTTP_VIA','HTTP_X_FORWARDED','HTTP_X_FORWARDED_FOR');
foreach ($headers as $header) {
if (isset($_SERVER[$header])) {
header("Location: /proxy-not-allowed/");
die;
}
}
$queryIP = "SELECT `user_ip_address` FROM `my_table` WHERE `user_ip_address` = :user_ip_address AND `user_blocked` = :user_blocked LIMIT 1";
$queryIP1 = $pdo->prepare($queryIP);
$queryIP1->execute(array(':user_ip_address' => $user_ip, ':user_blocked' => 'No'));
$queryIP2 = $queryIP1->rowCount();
if ($queryIP2 === 0) {
$ports = array(80, 81, 553, 554, 1080, 3128, 4480, 6588, 8000, 8080);
foreach ($ports as $port) {
$connection = @fsockopen($user_ip, $port, $errno, $errstr, 0.1);
if (is_resource($connection)) {
header("Location: /proxy-not-allowed/");
die;
}
}
}
?>
The headers script blocks any proxy sending those headers while the ports script blocks those using any assigned ports I add. I have tested this which seems to be good, though it won't block all proxies due to the assigned one I have. Is this the best way to go about blocking scripts if I don't have access to the firewall? What I am trying to do is allow users to view my HTTPS website normally and block all proxies. Even if I have some users blocked, I do not want them to be cheeky and use a proxy or even register on my website through a proxy. I was thinking of just using the 443 port as my website is https (is that wise?). Any advice would be great. Edited January 4, 2019 by Cobra23 hi

Edited by ShivaGupta, 23 May 2014 - 04:49 PM. I was wondering if there was a way or if it's even possible to determine the type of a proxy using php. When I say type I mean http, socks4 or socks5. Using cURL I think it's safe to assume that if a proxy returns a code of 200 then that proxy is good and http, correct? However, how would I go about determining the type of proxies I have in a list, assuming they are good and socks4 and/or socks5? I'm going to write a script that determines if a proxy is good or not through cURL and I would like to know if anyone knows what qualifies a proxy as being good. Let's assume I need to do some surfing through a proxy - that's it. Is there a way in PHP to determine the 'type' of proxy? For example (elite, codeen, etc.) If the proxy page exists is that all I need to run cURL through it or otherwise consider it as being good? Or should I focus my attention towards simply going through the whole process of getting a 'dummy' page using cURL through the proxy and, should it succeed, it will be considered good. I suppose if I can avoid the latter then the script would be more efficient. Advice and suggestions are always greatly appreciated here. Received HTTP code 403 from proxy after CONNECT Code: [Select] <?php function getPage($proxy, $url, $referer, $agent, $header, $timeout) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, $header); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_PROXY, $proxy); curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); curl_setopt($ch, CURLOPT_REFERER, $referer); curl_setopt($ch, CURLOPT_USERAGENT, $agent); $result['EXE'] = curl_exec($ch); $result['INF'] = curl_getinfo($ch); $result['ERR'] = curl_error($ch); curl_close($ch); return $result; } $result = getPage( '89.106.13.93:80', // use valid proxy 'http://www.northplanet.co.uk', 'http://www.youtexv.com/', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.8) Gecko/2009032609 Firefox/3.0.8', 1, 5); print_r ($result); ?> Using Slim to route endpoints to my application. In addition, I have many endpoints (mostly accessed via xhr) which need to be forwarded to another server, and I am using Guzzle to do so. Note only do I have to transfer text/json, I also have to send and retrieve files (currently only csv files, but will later add pdf). Accomplishing this was easier than I expected, but expect I may still be doing certain portions wrong. Anything look off, especially with the multipart forms for file uploads as well as the downloading of files? Thank you

I was on a proxy and it didnt detect it, idk why. if(!empty($_SERVER['HTTP_X_FORWARDED_FOR']) || !empty($_SERVER['HTTP_X_FORWARDED']) || !empty($_SERVER['HTTP_FORWARDED_FOR']) || empty($_SERVER['HTTP_CONNECTION']) || $hostaddr == "." || stripos($hostaddr, "tor-exit") || !empty($_SERVER['HTTP_VIA']) || empty($_SERVER['HTTP_ACCEPT_ENCODING']) || in_array($_SERVER['REMOTE_PORT'], array(8080,80,6588,8000,3128,553,554)) ) { die('on Proxy'); Guys, I recently came across this about using a tor socks proxy as a default proxy server in my local home network. So, to my centos-box, I've set the service up with a default soks-port 9050 and the local ip address of this machine is 10.10.1.5. Here's a part of the tor's config file:
SocksPort 10.10.1.5:9050
[jazz@centos-box ~]$ top -u jazz | grep tor 3413 jazz 20 0 76256 32m 9720 S 0.0 0.3 0:01.55 tor [jazz@centos-box ~]$ nmap -Pn 10.10.1.5 | grep 9050 9050/tcp open tor-socks Now, I'm completely able to use that socks proxy from the centos-box with my default browser / curl or whatever you want to be, but if I go to my laptop and set the proxy-socket up to its browser, I've got a message of "TOR is not an HTTP proxy" and half or more ( not all of them ) of my bookmarks web-sites don't work. However, a message when I'm running this service says: Sep 12 13:16:01.769 [notice] You configured a non-loopback address '10.10.1.5:9050' for SocksPort. This allows everybody on your local network to use your machine as a proxy. Make sure this is what you wanted. Sep 12 13:16:01.769 [notice] Opening Socks listener on 10.10.1.5:9050 Ideas? Edited by jazzman1, 12 September 2014 - 12:39 PM. Hello, hello i need use curl with proxy. but i get "undefined variable offset 1" error . here is the standart code i use. please help me about it thanks curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, $header); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_PROXY, $proxy); curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); curl_setopt($ch, CURLOPT_REFERER, $referer); curl_setopt($ch, CURLOPT_USERAGENT, $agent); Hello Is there any way to find out what is type of proxy? I mean Anonymous, Transparent etc. Cannot Get IP Address Behind A Proxy Server.I am using $aph = apache_request_headers(); print $aph['PC-Remote-Addr'] . "<br/>"; print "HTTP_CLIENT_IP: " . $_SERVER["HTTP_CLIENT_IP"] . "<br/>"; print "HTTP_X_FORWARDED_FOR: " . $_SERVER["HTTP_X_FORWARDED_FOR"] . "<br/>"; print "REMOTE_ADDR: " . $_SERVER["REMOTE_ADDR"] . "<br/>"; print "CLUSTER CLIENT " . $_SERVER["HTTP_X_CLUSTER_CLIENT_IP"] . "<br/>"; exit; but does not give output.Please suggest me how to get ip behind proxy server. I have some videos stored above web root. I then have a PHP file that acts as a proxy to hand the videos to the user. The reason for this is so not just anybody can download the videos. They have to be authenticated. If I am on the PC, it prompts for a download so I know the script is working. When I try it on my iPad, I get the big play button but with a cross through it. When I try it on my iPhone, the movie interface loads, but I am then prompted with "Cannot play movie: The server is not correctly configured" What could that be referring to? My script is below: <?php include("config.php"); //just includes session_start and db connection if ($_SESSION['user']['authed'] == true) { session_write_close(); $id = $_GET['id']; $query = mysql_query("SELECT filename FROM episodes WHERE id = '$id'"); $row = mysql_fetch_array($query); $filename = "../../media/".$row['filename']; header( 'Content-Description: File Transfer' ); header( 'Content-Type: application/octet-stream' ); header( 'Content-Disposition: attachment; filename='.basename( $filename ) ); header( 'Content-Transfer-Encoding: binary' ); header( 'Expires: 0' ); header( 'Cache-Control: must-revalidate, post-check=0, pre-check=0' ); header( 'Pragma: public' ); header( 'Content-Length: ' . filesize( $filename ) ); ob_clean(); flush(); readfile( $filename ); exit; } ?> Our website now is using Proxy we would like to get the Visitory IP.
We try to get using
HTTP_X_FORWARDED_FOR
but it seems that doesn't get the IP. Were running the site on IIS.
So, I have this web crawler that I want to use to index .onion websites through the TOR network. I amOk, here's what I need. I have a PHP based web crawler. It is accessible he http://rz7ocnxxu7ka6ncv.onion/ Now, my problem is that my spider that actually crawls pages needs to do so on a SOCKS port 9050. The thing is, I have to tunnel its connection through TOR so that It can resolve .onion domains, which is what I'm indexing. (Only ending in .onion.) I call this script from the command line using php crawl.php, and I add the appropriate parameters to crawl the page. Here is what I think: Is there any way to force it to use TOR? OR can i force my ENTIRE MACHINE to tunnel things through tor, and how? (Like forcing all traffic through 127.0.0.1:9050) perhaps if i set up global proxy settings, php would respect them? If any of my solutions work, how would I do it? (Step by step instructions please, I am a noob.) I just want to crate my own TOR search engine. (Don't recommend my p2p search engines- it's not what I want for this- I know they exist, I did my homework.) Here is the crawler source if you are interested to take a look at: Perhaps someone with a kind heart can modify it to use 127.0.0.1:9050 for all crawling requests? spider.php: http://pastebin.com/kscGJCc5 spiderfuncs.php: http://pastebin.com/m5y54RUh PLEASE someone help me! I am desperate. |
