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.

        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 (
        yellow.centroid.eu (
        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. :-)

April 1st approaching

March 30th, 2019

While the western world makes jokes on april 1st. I believe this day is dead serious. I was never one for making silly jokes on this day.


Going to rent three more vps's

March 30th, 2019

The month of march had its interruptions. I had a lead for a job but it turned out to not be fruitful. So for April I'm prioritizing my dns server work and work on my vps network. I'm going to get three vultr vps's to replace omega.virgostar.net.

The three will do the exact same function but will cost 50 cent/mo less than omega, so around 9.50 USD/mo. This brings my network temporarily up to 7 vps's and I'm going to have to monitor them. I'm going to install nagios on red. I have a new naming scheme. I call it the rainbow vps's. Red, green, blue, orange, yellow and purple. A seventh named indigo will have to wait until needed to make the 7 colours of the rainbow happen.

The nagios will likely only ping the remote hosts and report them as down or not. Maybe it will monitor smtp ports as well. So that's what's happening in april.


Living with Schizophrenia: We are the 1%

March 29th, 2019

Genetically we differ from the rest of humanity, but we are part of the human family. Behaviourly we differ as well, often we are loners, because any form of making contact to the 99% is misunderstood and coupled with embarrassment when signals are mistaken. Yes we are probably what the Neanderthals were in the old days when they existed. We are ostracized often by others. We are the people that are blamed when things go wrong. And simply put we are often used just to find excuses when things don't go right, say at work. Hitler did not have schizophrenia nor did the Nazi's, in fact they euthanised people with mental illness and disorders and did them like the jews. So I find it weird that particularily in german society people still make a negative out of someone who is a born outcast (see previous article). Yes it may be that we are hypocrite, because society is holding out the guns, drugs, weapons, sins and what have you. We are the ones that are tempted a lot quicker to misuse these things, it's a failure of good judgement. When badmindedness is rewarded with drug-use in this society who looks beyond it? It's us when we had enough. What is a bad mind, what is evil? Who is to judge another human before god for what they're thinking? Sure temptations can mislead us and have in the past. To me it's only human, an attack on my kind is an attack on me though, we are not the same and we differ even in our own ranks. Go study an alien or something eh?


Schizophrenic bashing

March 29th, 2019

Jan Fleischhauer starts the bashing none too soon, early enough for the schizo season. I'm disgusted at this. He likens Holocaust denial with Schizophrenia, calls it digital schizophrenia. Jan, you're messed up, retract your article.


Thinking of switching language of this blog

March 27th, 2019

When Great Britain leaves the EU, there may not be a reason to speak english anymore to reach EU citizens. What may happen (not sure yet), is that I'm going to switch to german. Only if Ireland is still in the union and the one official language is english will I think of keeping english. By now a lot of translators exist to make comprehension of any language possible, I think it's even built in to chrome. Just wanted to put the thought out there, not to scare you, but to let you know I'm considering this. I have mediocre french skills perhaps I should switch to french? :-)


Internet vs. EU (are we all prisoners of a regime?)

March 26th, 2019

The EU just dipped in popularity. If it comes to a showdown between the Internet and EU I'll take my hat and join the Netizens. I've been a netizen since 1994, how long have I been a EU citizen? Probably not that long. If you haven't heard by now the EU has passed legislation that upload filters (ie. article 13 and 11) are going to be required on platforms such as google/youtube and facebook.

This puts a damper on freedom for a large chunk of the population. I was considering voting for the SPD in some sort of europe election (if we actually get to vote in this thing), now I'm not so sure. We'll have to review who voted what in the EU parliament. I'm looking forward to the OneWeb and Starlink satellites which I'm considering to get linked to. As we do not need a partitioned Internet and this is the answer regarding this threat.
