App is ajax-based using jQuery libraries, it uses php scripts and javascript and some HTML5 features, so some modern browser is preferred to be able to display javascript quickly/correctly…

Some main features include:

• Section / Subnet separation
• IPv4/v6 support
• Displays free range and number of clients
• Subnet statistics
• User management
• E-Mail notification
• Import IP addresses from XLS / CSV file
• IPv4/v6 calculator
• Search IP database
• and many others.

If there will be interest I plan to launch it as an open source project. Next plans for v 0.2 are use of domain authentication, viewer-only user type, rss change feed, mass edit/delete/create, etc.

App can be tested on the following demo page:
ipamdemo

mysql> select ipaddr from ipaddresses order by ipaddr asc;

As you can see the .123 should come last but it is in second place… The solution is to use mysql's aton function, which transforms IP into integer and sorts the fields properly…

mysql> select ipaddr from ipaddresses order by INET_ATON(ipaddr) ASC;

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:73 errors:0 dropped:0 overruns:0 frame: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:

Gentoo Linux provides one of the most highly configurable Operating Systems around. Although the time spent installing and configuring Gentoo can turn out to be days instead of hours, the final installation will be totally optimized and customized to how you use your computer.

Zadnje case opazam, da je veliko manj tezav pri nadgradnji paketov…

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.

Same instalacije se nebi dotikal, kot vedno je odvisna od platforme… V kolikor nalagate binarne pakete bi morali imeti ipv6 podporo po defaultu omogoceno, v nasprotnem primeru ne pozabite sestaviti squida s podporo za ipv6.

Nastaviti moramo sledece:

• IPv6 nastavitev dostopovne tocke (APN) na telefonu ali
• Nastavitev brskalnika, da uporablja proxy streznik (google it!)
• IPv6 konfiguracija streznika

IPv6 APN nastavitev na telefonu

Tools -> settings -> Connection -> Access Points
Dodamo novo dostopovno tocko ipv6 – proti ipv4 se spremeni sledece:

• Access point name – to dobite pri vasem operaterju (v prihodnosti )
• Advanced settings – Network type: ipv6
• Advanced settings – Proxy ser.add: [2a02:xxx:xxx::1] – (ja, potrebujete oglate oklepaje)
• Advanced settings – Proxy port number: 8080

Konfiguracija squid streznika (squid.conf)

Izpostavil sem samo za IPv6 relevanten del konfiguracije, seveda predvidevam, da imate delujoco IPv6 mrezo:

# acl ipv6 networks
acl ipv6clients src 2a02:xxxx:xxxx::/48
# permit access to ipv6 clients
http_access allow ipv6clients
http_access deny all
# Squid listen ip/port
http_port [2a02:x:x::x]:8080

Clean & simple, to je to! Sedaj lahko zazenemo streznik:

/usr/local/squid/bin/squid -z	 (kreiramo dir za cache)
/usr/local/squid/bin/squid -NCd1  (za zacetek debug mode)

Se preverimo, ce poslusa na zeljenem portu (na linuxu je komanda netstat -tunlp | grep 8080):

[root@mihap ~]# sockstat | grep 8080
USER  COMMAND     PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
squid    squid        56306 13 tcp6   2a02:x:x::x:8080*:*
[root@mihap ~]#

in mogoce se pf inbound rule, v kolikor ga uporabljate:

myip6 = "2a02:x:x::x"
ipv6clients = "2a02:xxxx:xxxx::/48"
pass in quick on bce0 inet6 proto tcp from $ipv6clients to $myip6 port 8080
block in log all on bce0 inet6 from any to $myip6

Preverimo se lignjev log file:

2a02:x:x:x::x - - [06/Jan/2010:09:45:16 +0100] "GET http://ipv6.google.com/ HTTP/1.1" 200 1682 TCP_MISS:DIRECT

Once you are logged onto device you have to issue following command, with which you see the supported connection types: at+cgdcont=?. Here is the output from my Novatel mc990D card:

at+cgdcont=?
+CGDCONT: (1-16),"IP",,,(0-2),(0-3)
+CGDCONT: (1-16),"PPP",,,(0-2),(0-3)
+CGDCONT: (1-16),"IPV6",,,(0-2),(0-3)

If you see a third line (yes, the ipv6 one) then you are good to go.
