After few tries I managed to get it working, there is just a small, simple trick: IPv4 public address must be set to manually configured static IP address, it does not work with DHCP server, even if the IP address you get is always the same. And since there is no logging output to make troubleshooting figuring this out can be a problem…

After that it works great… IPv6 to the home!

Anyway, once we have IPv6 connectivity to internet we can also setup device to act as web server – since it is a Linux device this is not too hard to do. However, most mobile operators block the incoming TCP connection toward clients to prevent overcharging, so contact your ISP to verify if incoming connections are allowed. Here is the output from my ifconfig, that shows two active mobile data interfaces and sessions, one for IPv4 and second for IPv6:

gprs0     Link encap:UNSPEC  HWaddr *
          inet addr:10.10.9.14  P-t-P:10.10.9.14  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP  MTU:1400  Metric:1
          RX packets:1158 errors:0 dropped:0 overruns:0 frame:0

gprs1     Link encap:UNSPEC  HWaddr *
          inet6 addr: 2a02:840:beef:30::2/0 Scope:Global

          RX packets:73 errors:0 dropped:0 overruns:0 frame:0
          TX packets:66 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:8680 (8.4 KiB)  TX bytes:39414 (38.4 KiB)

For Apache to run we have to first install the Easy Debian package for N900, and after that the libapache2-mod-php package inside chrooted environment, which installs all required packages because of dependancies. Volia! We can verify that apache is listening on IPv6 interface by entering the following command:

[root@deb-m5v3d: /]netstat -tunlp | grep apache
tcp6     0    0    :::80    :::*      LISTEN   2009/apache2
[root@deb-m5v3d: /]

the :::80 means we are listening on all IPv6 interfaces on port 80. Here are some screenshots, just apache showing the basic php info:

Server localhost:

Client access to server:

All other apps should work also…

The simplest possible example you can find on http://mihap.si/share/captcha/.

What we need:

• HTML code and php image generation code
• jQuery library and script
• PHP page for input verification

1.) HTML code

We will use the simplest html input form, besides captcha input we will also add additional name field to demonstrate multiple input posting. For PHP image generation I will use the code from original guide, as no modifications are made.

HTML code (index.html):

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> 

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

<head>
	<title>Captcha test site
	<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>

<body>

<!-- form -->
<form id="myform" method="post">
	Name:
	<input type="text" name="name"><br>
	Captch code:
	<input type="text" name="userinput"><br>
	Captcha image:
	<img class="captcha" src="captchacreate.php"><br>

	<input type="submit" value="Verify">
</form>

<!-- result holder -->
<div class="result"></div>

</body>
</html>

PHP image generation code (captchacreate.php):

<?php
//Start the session so we can store what the security code actually is
session_start();

//Send a generated image to the browser
create_image();
exit(); 

function create_image()
{
    //Let's generate a totally random string using md5
    $md5_hash = md5(rand(0,999));
    //We don't need a 32 character long string so we trim it down to 5
    $security_code = substr($md5_hash, 15, 5); 

    //Set the session to store the security code
    $_SESSION["security_code"] = $security_code;

    //Set the image width and height
    $width = 100;
    $height = 22;  

    //Create the image resource
    $image = ImageCreate($width, $height);  

    //We are making three colors, white, black and gray
    $white = ImageColorAllocate($image, 255, 255, 255);
    $black = ImageColorAllocate($image, 0, 0, 0);
    $grey = ImageColorAllocate($image, 204, 204, 204); 

    //Make the background black
    ImageFill($image, 0, 0, $white); 

    //Add randomly generated string in white to the image
    ImageString($image, 3, 30, 3, $security_code, $black); 

    //Throw in some lines to make it a little bit harder for any bots to break
    ImageRectangle($image,0,0,$width-1,$height-1,$grey);
    imageline($image, 0, $height/2, $width, $height/2, $grey);
    imageline($image, $width/2, 0, $width/2, $height, $grey);
    //imageline($image, 0, 0, $width, $height, $grey);
    imageline($image, $width, 0, 0, $height, $grey); 

    //Tell the browser what kind of file is come in
    header("Content-Type: image/jpeg"); 

    //Output the newly created image in jpeg format
    ImageJpeg($image); 

    //Free up resources
    ImageDestroy($image);
}
?>

As you can see we create new session variable "security_code", into which we store the captcha code and display the created image on page. The same code must be entered through html user input form and then validated.

2.) jQuery

For jQuery source you can download the latest version on download page, or just include this link in index.html page header:

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>

Now we have to tell jquery what to do with page – after the form with id myform is submitted, get all the variables, execute the ajax post function and in div result display the result of check.php function, into which we submit the entered variables. Also, we have to reload the image and reset the security_code:

<script type="text/javascript">
$(document).ready(function()
{
$('#myform').submit(function() {
	//get user input and create random number
	var input = ($(this).serialize());
	var rand = Math.random();

	//submit post to check.php and reload image
	$.post('check.php', input, function(data) {
  		$('div.result').html(data);
  		$('img.captcha').attr("src", 'captchacreate.php?' + rand);
	});

	return false;
	});

return false;
});
</script>

3.) PHP verification code

After the form is submitted, we have to check the user entered input against the security_code session variable. If all is ok, we display success and display the entered name – check.php:

<?php
session_start();

//Check if the security code and the session value are not blank
//and if the input text matches the stored text
if ( ($_REQUEST["userinput"] == $_SESSION["security_code"]) && (!empty($_REQUEST["userinput"]) && !empty($_SESSION["security_code"])) ) {
	print '<h1>Input verification ok!</h1>';
	print 'Welcome, '. $_REQUEST['name'];
}
else {
	print '<h1>Input verification failed!</h1>';
}

?>

That is it. You can add more inputs as you like, checkboxes etc, no changes to jquery code is required as .serialize() function will take care of that. Of course the image generation is not good enough, php code must be enhanced to make it unreadable by computers, some hints are on original post, you can also search the web for php image generation.
