PHP - Php Curl Proxy Server

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.

I have full access to the webserver (Its a VPS0.
I just don't know how to fix it.

i have php at server side and c++ at client side.what i am trying to do is to constantly look for files on server in folder on server if there’s a file in folder then download it on client side and delete it from server folder
this will happen again and again after 5minutes if a file is present on server in folder then download it and delete from server then in c++ goto sleep again fro 5 minutes and after 5 minutes do all this again if no file present in folder on server then simply do nothing.

Hi there,

I'm writing an application that pulls from two separate web based APIs, collates the data into a single array of data.  Once done, it then enters a loop that cycles through the array and executes a cURL call for each cycle.  This worked perfectly for a controlled set of 10 artificial records and so I've started testing with live data.

On running the code, I eventually the following :
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

I'm not sure how to debug this and so I'm hoping I can find some help here.
I'm running WAMP, and the php.ini contains the following:
max_execution_time = 0   ; Maximum execution time of each script, in seconds
max_input_time = 0   ; Maximum amount of time each script may spend parsing request data

Through testing, I have discovered the following :
The script can do exactly 35 iterations through the loop in under 2 minutes.
Any number greater than this causes the error.
If I skip the first 20 curl submits, I can then do 21 to 55 iterations before failure, so I do not believe it is the 36th value.
If I put a sleep(5) command into the loop, I can still do 35 and no more iterations than that.
If I put a sleep(10) command into the loop, it fails on 35 and needs less.

Code: [Select]
$action = "post";
$url = "http://url.url.url/api/v1.0/udo_Position/create"; // I've replaced the actual URL out of necessity

// set user agent {
print("Setting CURL options, using URL ".$url."<br>");
$cd = curl_init();
curl_setopt($cd, CURLOPT_HEADER, 1);
curl_setopt($cd, CURLOPT_URL, $url);
curl_setopt($cd, CURLOPT_USERPWD, 'username:password');
curl_setopt($cd, CURLOPT_RETURNTRANSFER, 1); // Don't send return value to screen
curl_setopt($cd, CURLOPT_USERAGENT, "Firefox/2.0.0.1"); // spoofing FireFox 2.0
curl_setopt($cd, CURLOPT_VERBOSE, true);
// }

if ($action == 'get') {
;
} elseif ($action == 'post') {
print("POST set;<br>");
print("<pre style='font-family:verdana;font-size:13'>");
print_r($pointval);
print("</pre>");
$pointval["save"] = "Save"; // The AddNew step form requires this.

curl_setopt($cd, CURLOPT_POSTFIELDS, $pointval);
} else {
print("Invalid usage. Please see example<br>");
return;
}

$reply = curl_exec($cd);

$http_status = curl_getinfo($cd, CURLINFO_HTTP_CODE);
print("<pre style='font-family:verdana;font-size:13'>");
print_r($http_status);
print("</pre>");

print("Here is the reply from the AddNew function: <br>");
print("<pre style='font-family:verdana;font-size:13'>");
print_r($reply);
print("</pre>");

if (curl_error($cd)) {
print("Error: ".(curl_error($cd))."<br>");
}

curl_close($cd);
print("Insert Successful.<br>");

I am uncertain whether it is a PHP, Apache or cURL issue at this point.  I have another script that pushes a great deal more cURL calls to the same system but pulls from only one external resource, instead of two.  Any help or suggestions would be appreciated.

Hey All,

I will be marketing a simple php script shortly and would like to Obfuscate my code and have it check to see if the person is running the script on the proper domain, much like other Purchased Scripts, you have to buy licenses and some are limited to a Per Domain basis.

Could I use cURL to run a script on another server (mine) that takes the URL it came from, and a variable "the auth key" and check if the person is using the script on the proper domain?  If the domain and auth key don't match in the DB i would return a message saying invalid key or something, else continue to execute the script.


<?php
//authkey would be defined in config file
$authkey = "769870afhljkzxf90436";

$curl_handle=curl_init();
curl_setopt($curl_handle,CURLOPT_URL,"http://example.com/page.php?authkey=$authkey");
curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
$buffer = curl_exec($curl_handle);
curl_close($curl_handle);

if (empty($buffer))
{
    print "Sorry, AuthServ is performing maintenance.....<p>";
}
else
{
    print $buffer;
}
?>



Is there a smarter way to do this?  I don't have an extra 300 bucks to use something like ioncube,  just looking for a general proper direction on going about this as I am totally clueless.

thanks

    
    $account="54646456456464";
    $station= "12345";
    $options="11-1";
    $image="C:/Desktop/Sample Images/usco1.jpg";
    
    
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,"http://dfdgfsfs.com/kgdfgd.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
            'image' => '@'.$image, 'account' => $account, 'station' => $station, 'options' => $options));


$postResult = curl_exec($ch);


curl_close ($ch);

$xmlobj = simplexml_load_string($postResult);

echo (string)$xmlobj->ID->attributes()->value;
echo (string)$xmlobj->FullName->attributes()->value;

All, I have spend days trying to figure this out without any luck.  I am now in crisis mode.  I need to get this working asap.  The following code works perfect on my local xampp machine.  As soon as I upload it to my web server, I don't get any data back.  I have narrowed it down to the image i am trying to send is not being received properly.  Thanks in advance.

Hi All,

My goal is to process all redirects serverside and simply return the user to the 'final' URL.

Here's my function to get the final URL:
PHP Code:
function get_final_url($url){ 
    global $final_host; 
        $redirects = get_all_redirects($url); 
        if (count($redirects)>0){ 
          $final_url = array_pop($redirects); 
          if(substr($final_url,0,7) != 'http://' && !empty($final_host)) 
            { $final_url = 'http://'.$final_host.$final_url; } 
                return $final_url; 
        } else { 
                return $url; 
        } 

Here's the cURL execution:

$ch2 = curl_init();      
                        curl_setopt($ch2,CURLOPT_URL,$url); 
                        curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true); 
                        curl_setopt($ch2,CURLOPT_POST,''); 
                        curl_setopt($ch2,CURLOPT_POSTFIELDS,''); 
                        curl_exec($ch2); 
                        curl_close($ch2); 

For some reason, this works no problem, posts any data over to the URLs serverside, redirects serverside, and passes the client to the final URL, with none of the redirection displayed via HTTPWatch or any similar debug utility. Sometimes, however, it does show phases of redirection.

Any insight into what I might be doing incorrectly?

Thanks SO much in advance.

good day dear community,

i am workin on a Curl loop to fetch multiple pages:

i have some examples - and a question:

Example: If we want to get information from 3 sites with CURL we can do it like so:


$list[1] = "http://www.example1.com";
$list[2] = "ftp://example.com";
$list[3] = "http://www.example2.com";


After creating the list of links we should initialize the cURL multi handle and adding the cURL handles.


$curlHandle = curl_multi_init();
for ($i = 1;$i <= 3; $i++)
 $curl[$i] = addHandle($curlHandle,$list[$i]);


Now we should execute the cURL multi handle retrive the
content from the sub handles that we added to the cURL multi handle.

ExecHandle($curlHandle);
for ($i = 1;$i <= 3; $i++)
{
 $text[$i] =  curl_multi_getcontent ($curl[$i]);
 echo $text[$i];
}

In the end we should release the handles from the cURL multi handle by calling curl_multi_remove_handle and close the cURL multi handle!

If we want to another Fetch of sites with cURL-Multi - since this is the most pretty way to do it!
Well I am not sure bout the string concatenation. How to do it - Note I want to fetch several hundred pages:
see the some details for this target-server sites - /(I have to create a loop over several hundred sites).

    * siteone.example/?show_subsite=9009
    * siteone.example/?show_subsite=9742
    * siteone.example/?show_subsite=9871

.... and so on and so forth Question: How to appy this loop into the array of the curl-multi?

$urls = array(

   );

$mh = curl_multi_init();

       $conn[$i]=curl_init($url);
       curl_setopt($conn[$i],CURLOPT_RETURNTRANSFER,1);//return data as string

       curl_setopt($conn[$i],CURLOPT_MAXREDIRS,2);//maximum redirects
       curl_setopt($conn[$i],CURLOPT_CONNECTTIMEOUT,10);//timeout
       curl_multi_add_handle ($mh,$conn[$i]);
}

do { $n=curl_multi_exec($mh,$active); } while ($active);

foreach ($urls as $i => $url) {
       $res[$i]=curl_multi_getcontent($conn[$i]);
       curl_multi_remove_handle($mh,$conn[$i]);
       curl_close($conn[$i]);
}
curl_multi_close($mh);


print_r($res);

?>





I look forward to your ideas.

Could someone give me a cross-domain proxy script?

I am trying to post data to mysql databases on two servers.

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;  
}

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!

Hi I need a script to hide  IP address with proxy and read a web page

$username="myuser";
$password="mypass";


$url = "http://www.mysite.com";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXY, '173.234.11.134');
curl_setopt($ch, CURLOPT_PROXYPORT,'80');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
$output = curl_exec($ch);
$info = curl_getinfo($ch);




echo $output;
curl_close($ch);
 

The script doesn't work, it doesn't show me the page output. Any solution?

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.

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?

Hi 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.
