Controlling Tor Network with PHP

[punk_runner]

I have a PHP app that I wrote that requires a new IP address each time that it is run. Currently I use Tor on my desktop and the Vidalia app to change the Tor identity each time I run the script but I want to automate this. Can anyone help with switching Tor identities with PHP? Essentially after my script runs I need to call a function that switches to a new Tor identity.

 

I have the following code but it doesn't seem to work, and I am not sure why. I am running this from XAMPP on OSX, Tor is running locally (client not server)... in my Tor settings I have 127.0.0.1 and port 9051, set to "no password"...

 

<?php
function tor_new_identity($tor_ip='127.0.0.1', $control_port='9051', $auth_code='') {
	$fp = fsockopen($tor_ip, $control_port, $errno, $errstr, 30);
	if (!$fp) {
		return false; //can't connect to the control port
	}

	fputs($fp, "AUTHENTICATE $auth_code\r\n");
	$response = fread($fp, 1024);

	list($code, $text) = explode(' ', $response, 2);
	if ($code != '250') {
		return false; //authentication failed
	}

	//send the request to for new identity
	fputs($fp, "signal NEWNYM\r\n");
	$response = fread($fp, 1024);
	list($code, $text) = explode(' ', $response, 2);
	if ($code != '250') {
		return false; //signal failed
	}

	fclose($fp);
	return true;
}

tor_new_identity();
?>

I've had experience with PHP, Tor and cURL all talking to each other . What "Doesnt seem to work" about your code? Error messages? Does auth fail?

Hi,

 

I am having a similar problem. I am working on win7-64 bit with WAMP 2.1. I am trying to do basically the same thing with the latest Vidalia ( including Tor 0.2.1.30 and Polipo ), running locally. I am using php 5.3

 

 

<?php

?

//include the class
//remember the configuration file is located in:
//proxyConfiguration.ini

include("./proxyConnector.class.php");

//get an istance of the proxy
$connection = proxyConnector::getIstance();

//connect to google.com and change my identity
//because "switchIdentityAfterRequest" is set to TRUE
//in the .ini file
$connection->launch("http://whatismyip.com", null);

//get the data  and show it
$data = $connection->getProxyData();

echo "<pre>";
print_r($data);

 

The class is attached.

 

My problem is that , I would like to switch Identity after each request ( I am querying http://whatismyip.com ) . this happens sometimes, but when I run my script too close together , temporally, the IP address does not switch ( If I wait longer it will ).  The following code snippet is running without obvious error when I step through it with xdebug:

 

/**
     *
     * Change identity in the Tor Network
     * (change public IP Address)
     *
     * @return bool
     *          true is new identity is created
     *          false is fail creating a new identity
     */
    public function newIdentity(){
            $fp = fsockopen($this->ip, $this->controlPort, $errno, $errstr, 30);
            if (!$fp) return false; //can't connect to the control port

            fputs($fp, "AUTHENTICATE ".$this->controlPassword."\r\n");
            $response = fread($fp, 1024);
            list($code, $text) = explode(' ', $response, 2);
            if ($code != '250') return false; //authentication failed

            //send the request to for new identity
            fputs($fp, "signal NEWNYM\r\n");
            $response = fread($fp, 1024);
            list($code, $text) = explode(' ', $response, 2);
            if ($code != '250') return false; //signal failed

            fclose($fp);
            return true;
    }

 

I think that some cacheing may be going on somewhere, or a connection is being maintained when it should not . As a php beginner, I don't know how to test this or where to look. I would appreciate any help.

 

Thank you in advance,

 

KC

 

PS - here is the ini file - I couldn't attach it

 

; this is the ini file for the proxy configuration
; this default value are for a TOR PROXY running
; on a local machine with HashedControlPassword method
; activated

[general]
; timeout
timeout = 300

; proxy ip
ip = 127.0.0.1
; proxy port (default value stands for polipo port)
port = 8118

[TOR]
; proxy control port
; be sure to enable control in your
; tor configuration file (/etc/tor/torrc)
controlPort = 9051

; the password setted in the HashedControlPassword
; set a tor control password with:
; tor --hash-password YOUR_STRONG_PASSWORD
;
; To use this default configuration file try:
; tor --hash-password t0rS3cr3tPwD
;
; left blank if you have configured TOR CONTROL PORT
; without a password
controlPassword = t0rS3cr3tPwD

; if true after every request the class try to change
; his identity and his userAgent
switchIdentityAfterRequest = true
