I added myself a sixxs.net IPv6 IP twice. One for my Roadwarrior Macbook and one for my Macmini. Installing and running it was quite easy:
sudo port install aiccu
and configure it aftwardes as described.

As i am not very used to remembering v6 IPs  – i added the both in my /etc/hosts which works very well.

What actually drives me crazy is the setup for IPsec….
Here is what if done so far – with more or less help from this pages:

1. Simple Configuration Sample of IPsec/Racoon
2. IPsec
3. IPsec HOWTO
4. tech-net: IPsec vs. OSX

I created a racoon.conf with a pre-shared-key. Afterwards i added my Security Policy Database(SPD) telling it to use Authentication Header and Encrypted Payload between the both systems.
details followin’ later.

What’s drives me mad – is first of:
The errors given by the setkey command are nearly completly awkward: for example : “The Address family is not supported by the Protocoll Family” – what exactly should that mean. Or the same configuration running on the one system fails running with a parse error on the other.
Help will be much honored.

Update:

Hi all,

i tried a while now to connect my two macs via ipv6. This is cool and works fine (via sixxs.net). But i like to use ipsec on ipv6 (and enhance the firewall to allow all encrypted traffic) and came across this little tutorial

http://www.kame.net/newsletter/20001119/

Realising that the macs got all at hands needed to give a direct host-2-host encryption i thought this would be easy. But using setkey/racoon is quite of hard.

my actual setkey – config looks like this:

#!/usr/sbin/setkey -f
#
# Flush SAD and SPD
flush;
spdflush;
spdadd 2a01:XXX:XXX:XXX::2 XXXX:198:XXX:XXX::2 any -P out ipsec
esp/transport//require
ah/transport//require ;
spdadd XXXX:198:XXX:XXX::2 2a01:XXX:XXX:XXX::2 any -P in ipsec
esp/transport//require
ah/transport//require ;

and my racoon.conf looks like

path pre_shared_key "/etc/racoon/psk.txt" ;
remote 2a01:XXX:XXX:XXX::2 {
exchange_mode main;
my_identifier user_fqdn "joe@macmini.ipv6" ;
lifetime time 24 hour ;
proposal {
encryption_algorithm 3des;
hash_algorithm sha1;
authentication_method pre_shared_key;
dh_group modp1024;
}
}
sainfo address 2a01:XXX:XXX:XXX::2 any address XXXX:198:XXX:XXX::2 any
{
pfs_group modp768;
encryption_algorithm 3des;
authentication_algorithm hmac_md5;
compression_algorithm deflate;
}


This all starts very well – The ip’s are exchanged counterwise on the second mac – and everything starts – but a ping6 terminates with a request timeout and i’m quite sure that there is nothing encrypted inbetween.

Just for your information. Apple brings an fine VNC Server and client with the default delivery. The client is a bit hard to find as it is not indexed:
“/System/Library/CoreServices/Screen Sharing.app”

This tool is finaly just an VNC Client – and it is allready IPv6 capable.

Actually my attention comes to some weird characters in my wordpress blog. Such as ü or ö as represantants of ä and ö. So i had a look into my mysql-db and saw that it was still on latin1. On my way to the clearance i got over that explanation. But still all howtos doesn’t work out for me. There are others allready had a look into it like fischerlander or Haidong’s Blog.

The Problem is more complex as it may look in the first place. Wordpress or PHPBB put the post in the database as they receive it from the Browser. While you can set your Browser on a special Characterset (iso-8859-1) – rather than auto-recognition – and ignore so the servers needs the result are this awkward entries. And furthermore i had the problem that the users had used Windows-1250, UTF-16 and iso-8859-1 mixed.

Startin’ to solve this problem i wrote first this little perl script to generate the awkward chars:

#!/usr/bin/perl
 
  use strict;
  use Encode qw/encode decode/;
  my @list = ( 0x00 .. 0xFFFF );
#  my $letter = "ä";
 
open CSV, ">lat_new.csv";
  foreach my $letter (@list){
  $letter = chr($letter);
  print CSV $letter.";;";
  my $utf8 = encode("UTF-8", $letter);
  print CSV $utf8.";;";
  my $utf16 = encode("UTF-16", $letter);
  print CSV $utf16."\n";
  }
  close CSV;

As this results in a big list and 99% of it is useless i just tried to identify the chars from the several codings that leads to my personal abuse. This results in the following little list of latin-code-combination and UTF-8 representants. It is very likely, if you have chinese or russian characters, you will have a slightly other list …

ö;ö;ß;ß;ü;ü;ö;ö;ü;ü;–;–;ö;ö;ü;ü; ; ;¡;¡;¢
;¢;£;£;¤;¤;Â¥;¥;¦;¦;§;§;¨;¨;©;©;ª;ª;«;«;¬;¬;­;­;
®;®;¯;¯;°;°;±;±;²;²;³;³;´;´;µ;µ;¶;¶;·;·;¸;¸;¹;¹;º;º;»;»;
¼;¼;½;½;¾;¾;¿;¿;À;À;Á;Á;Â;Â;Ã;Ã;Ä;Ä;Ã…;Å;Æ;
Æ;Ç;Ç;È;È;É;
É;Ê;Ê;Ë;Ë;ÃŒ;Ì;Í;Í;ÃŽ;Î;Ï;Ï;Ð;Ð;Ñ;Ñ;Ã’;Ò;Ó;Ó;Ô;Ô;Õ;Õ;Ö;Ö;×;×;Ø;Ø;Ù;Ù;Ú;Ú;Û;Û;Ãœ;Ü;Ý;Ý;Þ;Þ;ß;ß;à ;à;á;á;â;â;
ã;ã;ä;ä;Ã¥;å;æ;æ;ç;ç;è;è;é;é;ê;ê;ë;ë;ì;ì;í;í;î;î;ï;ï;ð;
ð;ñ;ñ;ò;ò;ó;ó;ô;ô;õ;õ;ö;ö;÷;÷;ø;ø;ù;ù;ú;ú;û;û;
ü;ü;ý;ý;þ;þ;ÿ;ÿ;

I used a little perl-script to sanitize my mysql-export and to dump it into a new file. For security purposes i created a new database in utf8.

#!/usr/bin/perl
 
use strict;
 
open CSV, "<my_csv.csv"; #List from above
$li =~ s/\n//;
close CSV;
 
#  use strict;
#  use Encode qw/encode decode/;
#  my @list = ( 0x00 .. 0xFFFE );
#  my $letter = "ä";
#  my %lat_utf;
#open CSV, ">lat_new.csv";
#  foreach my $letter (@list){
#  $letter = chr($letter);
#  print CSV $letter.";;";
#  my $utf8 = encode("UTF-8", $letter);
#  $lat_utf{$utf8} = $letter;
#  print CSV $utf8.";;";
#  my $utf16 = encode("UTF-16", $letter);
#  print CSV $utf16."\n";
#  }
#  close CSV;
 
my %lat_utf = split(/;/,$li);
#print %lat_utf;
open FILE, "<mydatabase.csv";
my @lines = <FILE>; 
close FILE;
 
foreach my $key (keys %lat_utf){
#	print $key. "\n";
#@lines = map{ s/$key/$lat_utf{$key}/g } (@lines);
	my @nel;
	foreach my $lin (@lines){
#		print $lin."\n";
		if ( $lin =~ /$key/g ) {
			print $lin;
		}
		$lin =~ s/$key/$lat_utf{$key}/g;
#		print $lin."\n";
		push @nel, $lin;
	}
	@lines = @nel;
}
 
open FILE, ">wdrede_kjr-UTF-8_fixed_new.sql" or die $!;
 
foreach my $lin (@lines){
  print FILE $lin;
}
 
close FILE;

This results in my special case to a more or less clean wordpress-blog. BUT i realy would think that wordpress and phpbb should check the browser settings and in what codepage the user had put in the comment or content. Because – otherwise it wouldn’t help much to have this converted over a long time…

As i mentioned before you can go for an other number system than the standard decimal. The Fibuncci-System as i named it creates a line of numbers which represants the possible maximum at the given place. An Example

The Rule for calculate a fib-number  to a decimal is Sum over all places(placenumber * number)

As you see the Fibunacce 10 is greater than fib 1 – recalculated to decimal it means 1 > 1. Looks a bit awkwards. How can one apple be bigger than one apple  - maybe he is bigger –

This system creates every decimal number more than once. Some of the people i talked about it found this realy not easy to understand.

But i think we are used to our time and date number system which is indeed  a number system persisting not on a sequence rather than a mixed set (which kids really have their issues to learn):

Not a step closer to my prime problem but fun it is still

Basicaly our normal number system persists on a very basic sequence:

F(n) = F(n-1) + 1 with a fix basis (Binary, Decimal, Hexadecimal)

But it came to my mind that basicaly prime numbers does not match that criteria very well to identify the nature behind them. As many had tried a sequence in that number system can’t be easily found.

We are used to our Clocks - They have a number system which persists on a 10/60/60/24 system. To calculate in this kind of systems is quite a bit harder as we are used to it. The idea to get a better grip on primes is now to change our usual kind of number system:

For example Fibunacci-Sequence: to a basis of one number
creates: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 while every number is a change of basis

And so on.  As you see the system does not delivers an uniqueness of an normal number system does – the question i like to lock at is: How does a system like above reacts on prime numbers? – because i have the feeling as if the primes have some unique charaterstics in those kind of number systems. As i’m not a full-time mathematician, but i am really keen to discuss this here or via email: jrspam-prime@web-d….de because it looks to me as if nobody has ever thought of changing the number systems on behalf of the prime number problem. Follow up will come…

Actually i’m not sure at all but this is what i’ve seen so far:

Today i was back from my vacation trip and i thought o’right going to upgrade to Firmware 3.1.2 and have a look into it. Right after seen it is going quit well i adjusted the new pwnagetool and everything went fine – besides 2-3h later i saw i don’t get a carrier signal. I had a look on the iphone of my wife and see. Everything is fine. Next step was to go back to the regular firmware and see – iphone is back to be an iphone and not just an very expensive version of an itouch. As i’m not really sure where this behaviour:

Network : Not active

in settings come from from my unawarness or from an new ability to see if an iphone is pwned… i will wait as i have not time for plain’ around and the phone has to work. The rest is more or less nice but not necessary.

Nochmal in Kurz auf Deutsch: Habe heute das iphone mal wieder mit dem pwnagetool bearbeitet. Leider hatte ich im anschluss kein Telefon mehr. In den Einstellungen stand: unter

Netzwerk : nicht Aktiv

obs vom jailbreaken kommt kann ich nur ahnen – jedenfalls ging es wieder nach dem zurücksetzen auf die normale firmware.

Today – i was on starcraft2.com and i had a look into the sources (just for a look) and was nearly astonished as they use in broad XML and XSL for Browsers to render the page. The effect is so amazing… i like the way you can tell the browser to include for example navigation and just put in the content. How this is indexed by the searchengines i have to find out soon. But it is really good style blizzard shows here…

Update:

It seems that google indicates the sites of starcraft2.com – that leads to an interesting conclusion:

the search-robot uses an engine that interprets the loaded sites and build the index on this interpretet html. Which by the way means u don’t know if google has some kind of testing mechanism where it looks for seo-builded sites against that what a user will see. It’s still interesting. i will test this soon…
