Goodbye Julia, I voted for you

April 15th, 2019

Julia Reda was MEP in EU parliament for 10 years. I don't know what sort of legacy she leaves behind but I remember voting for the Pirate Party last election and allowing her to take her seat in parliament. Now with the new EU elections coming up she will not be running this term. Goodbye Julia, you kept popping up in IT News sites I read and I think you did a good job, though it probably wasn't easy as the only Pirate in EU. In the new election I'm hoping to see the SPD get as many votes as possible. We will be going to the polls in May 2019. I'm voting for my local representative Kerstin Westphal. Good luck to all!

Delphinusdnsd, a 30 year project?

April 13th, 2019

I'm doing the counting up of years and how much longer I want to be involved with delphinusdnsd. Right now I have 15 years under my belt for it, and I'M hoping to go another 15 years until 2034. At that point I will be 58 and will likely want to finish up other projects before retirement.

Parallel to this I want to take delphinusdnsd to another level. A page server. The concept is the following. Pages of RAM are updated and read from a bunch of delphinusdnsd's on a 10 GbE network (possibly with bonding, so a 20 GbE network). The delphinusdnsd protocol is modified to allow 4096 byte pages in its format. The kernel on a computer is modified to talk DNS to this delphinus cluster and do the necessary operations. I want to scale lots of RAM on hardware that has little native RAM. And I want to see how good it'll scale.

With the latter project I want to start within the next 2 years and be finished by 4 years from now. I'll be 47 then. If it works well I may spin it off into an enterprise and try to make money off it. So to prototype this I want to buy a cluster of SoC's (like raspberry pis) and try with them until going further and buying a bunch of servers with lots of RAM that a delphinusdnsd will run on. Staying with 4 servers for prototype and final model is my plan.

This is my dreams and I hope I can achieve them before getting too old to do this stuff.

In my mind the CDROM, DVD, Bluray has died

April 13th, 2019

I still have 3 CDROM drives on 2 computers. Next year it'll be just 1 computer after I retire a workstation (see my computers). In 2023 the blueray drive will die with the workstation it's in and only an external CDROM drive will remain. I may as well start moving some CD's to ISO's and put them in a safe place.

I remember a time when I was very excited to get CD's from OpenBSD which were a product. I bought this product and felt good about it. I know OpenBSD disagrees with me with the technicalities of what a product is. I wish OpenBSD would in the future make products again and sell the product on memsticks. There is some really beautiful memstick designs out there with different colours and the chance to put logos on these. Ultimately the best USB stick that could be sold by OpenBSD would be an RTC clock coupled with a memstick which is read-only until a sunset date, then it switches read-write and you can write over the data on it. I'll keep dreaming.

Do you still have CD's? Have you thought about converting it to another format? I have ripped my parents CD collection to mp3's once (so they can listen in car), I think I'll need to do it again some day to make them flac format files which are lossless and currently my favourite audio format.

Firewalled sshd port

April 12th, 2019

I have whitelisted my sshd port. The time is right I think. Quantum computers exist. And RSA's days are numbered before it's broken. On top of that there has been a report on OpenBSD's misc mailing list of someone claiming they were hacked through sshd, I'm guessing only more of these reports will come in the future. This is just a precaution because I'll never log in from China.

Julian Assange Arrested in London

April 11th, 2019

Julian Assange has been arrested. He faces minor charges in London. However it is my opinion that it's imperative that he gets safe passage home to Australia on a non-stop flight that doesn't pass US territory. His self exile is a shameful waste, making me believe he was in a desperate situation. BBC story.

Fixed a bug in Delphinusdnsd

April 8th, 2019

The delphinusdnsd, when run with signed and non-signed zones had a bug with non-signed zones when the query had the DO bit set. The answer would always reply with TC bit set at that point. I fixed this yesterday afaik. A snapshot would fix this issue if you're running this daemon.

Next month is the blogs 10th Anniversary

April 5th, 2019

I'd like to celebrate but other than drawing something I don't know what else to do. I like the graphics on the blog right now though.

The TCP three way handshake

April 5th, 2019

One of the most basic things to learn is about the three way handshake of TCP. I learned this a good 23 years ago, and it got reiterated over time as I took courses *yawn*. Anyhow 18 years ago I did codeblue (cb) which is a forger but it doesn't receive traffic. So while playing around I modified a sniffer that I made 22 years ago with codeblue to establish a classic three way handshake. This is for educational use only. While I was there i modified this a little bit to answer ARP as well, and then explored windows port 135 a little. Unfortunately other than that windows doesn't ever close this port I found nothing wrong.

Changed nameservers

April 2nd, 2019

I changed the nameservers of my domains, with the new VPS that I got.

Registrar:
        Name: CSL GmbH Computer Service Langenbach   d/b/a  joker.com
        Website: www.joker.com

Name servers:
        blue.centroid.eu (2a01:4f9:c010:1b26::1)
        blue.centroid.eu (95.216.163.41)
        yellow.centroid.eu (45.63.119.195)
        yellow.centroid.eu (2001:19f0:6c01:1fad::1)

This is related to the article 2 spots down "Going to rent three more vps's". It turns out that it was only two more vps's because I couldn't find the plan for $3.50 in vultr's Frankfurt servers. So I got two $5 servers instead. They are called yellow and orange. Orange I'll make the new mail server, and yellow is dedicated for DNS. Blue is the renamed tau.virgostar.net (which I still have to rename in the reverse dns). All the colours of a rainbow nameing scheme. :-)
