Hi All
Today is World IPv6 day, you know about it right?! http://www.worldipv6day.org/
in that spirit I asked a few of our customers at Solido Hosting if they would like to join the fun.
They did :-)
So today on World IPv6 Day we have at least two danish sites running IPv6 - and also our own home page etc.
The sites are:

I love networks.
Ostinato Packet/Traffic Generator and Analyzer is a nice tool that too few people know about, lets see if we can change that :-)
First of all, what are we talking about? From the homepage of Ostinato
Ostinato is an open-source, cross-platform network packet crafter/traffic generator and analyzer with a friendly GUI. Craft and send packets of several streams with different protocols at different rates. For the full feature list see below. Ostinato aims to be "Wires More text

Hmm, does my blog still work ;-)
So, I work with IPv6 - as some might know already. I also know a lot about IPv6, at least I think so myself :-)
I really hate reading about IPv6 these days, except when reading news like:

OK, lets say you have a nice router running Junos in a remote location.
This device is running nicely, but you want to make sure you can control it, even while doing updates and other stuff from console. Enter the console server, conserver and some multiport seriel adapter - everything is fine. Usually I buy a Soekris from Wim at KD85.com for this purpose. The reason to use Soekris are, pretty cheap, very small, can run from Compact Flash even, runs OpenBSD, multiport serial car More text

IPv6 is coming, no doubt.
The level of interest at tech news sites like Version2.dk is growing - search for IPv6. The danish Science Minister Charlotte Sahl-Madsen was reported this week for talking about IPv6 (terrible article but hey, interest)
But still the level is nowhere close to being enough. So lets get started, push IPv6 now!

I have previously talked about Juniper SRX and IPv6 forwarding, where it is possible to get them to forward IPv6 packets. In packet-based mode:
[edit security forwarding-options]
hlk@bender# show
family {
inet6 {
mode packet-based;
}
}
I was thus very interested when I got hold of the release notes for JUNOS 10.2 which told about flow-based forwarding. I downloaded the 10.2 relase and upgraded my small testsystem which is a SRX210B - low memory model. It needed some cleanup to free space, and update went smoothly - but slowly More text

Wauw its been a while!
I will start blogging RSN, so watch out - just checking that everything is still running smoothly with the Ecto blog editor.
I have a few book reviews, done - but not posted
i have done a lot of amazing stuff lately, ok maybe not epic - but funny things that I would like to share.
Tonight is also DNSSEC at BSD-DK, so maybe we will meet?
Ohh and BTW, communication from me on blog, twitter, company homepage, etc. is going to be in english from now on. Tired of writing things in two languages!
Posted by at CEST 10:04 28/04/2010 in Freelance, work etc.
This is a blog entry I have wanted to write for so loooong, and why didn't I?
Perhaps because I thought it would be hard and complex, but it isn't hard to DNSSEC enable your resolving/caching nameserver!
Luckily for me Tykling has done all the hard work and thus I asked him and he helped me :-)
So this entry is a 3..2..1 step to DNSSEC enabling your resolving/caching BIND DNS server, mine runs on OpenBSD with the built-in chrooted BIND, so the config is in /var/named/etc/named.conf and the resulting parts are:

Så er der blevet tid til at skrive næste indlæg, øv hvor kan tiden flyve når man har det sjovt - eller arbejder.
De planlagte indlæg tager også længere tid end forventet, måske fordi jeg leger så godt :-) Planen for de indlæg der mangler er nogle helt nede på jorden eksempler med pakker, til rigtige formål. Altså eksempler på programmer som man reelt kan bruge i sit eksisterende arsenal med Nmap, Python, Perl, Nemesis osv.
Det første som er blevet mere færdigt er en lille sød IPv6 portscanner, som snildt kan udvides med mere funktionalitet. Ideen med portscanneren er at s More text

Update 15:14: Jeg er en tumpe, tcpdump virker - hvis man vælger det rigtige interface :-)
Hovsa, jeg tror julemanden kom forbi, for jeg har fået fat på en N900 til lidt leg :-)
Jeg har tidligere snakket en del om min Nokia N810 som jeg har leget en del med, både med tcpdump, airodump osv. - det er en sød lille hackerplatform. Dog er den lidt begrænset med specs:
