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. :-)

March 30th, 2019

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.
