If you ever wanted to do this, here's how:
Type about:config in firefox's browser and promise to be careful, find
the security.tls.version.min and set it to 1 instead of 0. That
disables SSLv3.

Citizen4
October 11th, 2014
There is a movie out by Laura Poitras called "citizenfour" it's the story of
Edward Snowden. In this
article (in german) they write that the NSA has infiltrated German,
Chinese, and South Korean networks with undercover agents as sysadmins in order
to get at the infrastructure of those countries. I personally would just
like to say to companies in Germany that not every foreign sysadmin is a spy
and there is only a few bad apples. And I'd like to say to sysadmins that
want to work in Germany, that perhaps you'll be watched on whatever you do
and any actions you may do may reflect on your work at specific networks.
As a hint if you encounter servers named "Kriminalpolizei" or "Bundespolizei",
consider that these are just honey pots. Stay away from them as they won't
let you log in anyhow. Aside from this caution you have to use your instincts
why a server named "FBI" may be set up in a place where it does not make sense.
Remember, authorities like to set up at hub points, not at edge networks. If
they set up at the edge I'd say there is a good chance that it's fake.

Money lookout
October 4th, 2014
I'm simply spending way too much money. I only made ~ 10% savings this year
of my income while at the same time the euro was so strong vs. the CAD that
I lost 1000 euros income this year. So the books I bought this year will have
to last until january. And in 2015 I plan on spending only 6-8 books. Also
donation money will be less I'm cutting it by 1/3. I really have to tighten
the belt if I want to achieve a certain amount of savings in mid-2016. I
don't know if it's doable. But we'll see.

Tried the firechat app
October 3rd, 2014
I read somewhere that firechat is being used to organize protesters in HK.
So I tried it out and it drained my batteries overnight on my ipod. I quickly
deleted it again, good thing today is a holiday in germany, as the ipod didn't
wake me.

Pre-Ordered OpenBSD 5.6
September 30th, 2014
I have pre-ordered this from OpenBSDStore.COM, which is the old
openbsdeurope.com
website. Had some problems manouvering through their site at first but after
an email and assurances that everything was alright from them, I managed to
do my pre-order. Looking forward to having the three disks of freedom in my
hands!

Two TCP traceroutes
September 30th, 2014
I have written two programs that do a tcp traceroute to a remote IP. I plan
on finding the culprit at DTAG that gives me packet loss to my openbsd laptop
from the host io.solarscale.de. I wrote on it most of yesterday and got it
working somehow. Here is the source code for the
server traceroute and here is the source code for the
client traceroute.
The server gets connected upon with telnet and it will spit back some data
while tracing on its side (it doesn't fork), the client will connect to the
echo port or discard port which ever one it finds first and will do a
traceroute. Here a small demonstration of how the server tcp traceroute works:
root@galileo:/home/pjp/mytcptraced # ./mytcptraced 0.0.0.0
now sending from port 88 to port 55233, sending a few lines of test
sending testline 0 length 4
now starting the trace...
1 188.40.5.65 1292 1304
2 213.239.236.81 442 514
3 213.239.245.101 527 610
4 213.239.245.14 5129 5136
5 213.239.245.1 5223 5230
6 80.81.193.7 6095 6103
7 188.174.202.201 12422 13179
8 188.174.202.201 11944 12671
9 188.174.202.201 14382 14854
10
What's so cool about this is that it unearths routers behind NAT, as seen with
188.174.202.201 the last hop. This is my home address at m-net. Unfortunately
it can't unearth the RFC 1918 addresses due to some pretty good NAT on ICMP
timex messages, but knowing that this network goes deep is interesting too.
Anyhow enjoy the code, and play if you wish.

Wildcarddnsd Linux now relies on LibreSSL
September 28th, 2014
I have made wildcarddnsd's linux port rely on LibreSSL. This was not easy
because libressl does not exist in ubuntu or raspbian (the flavours I use).
So what I did was make it rely on libressl 2.0.5, and it extracts .o files
from the .a archive with ar, for functions that it needs. This seems to go
well. Just costs a bit of compile time. Roughly one hour on raspberry pi to
compile libressl 2.0.5.
I also checked all architectures except NetBSD whether they compile so that
I can release wildcarddnsd 0.9.0 in mid-November, as I don't know if I'll
have much time in October to work on it.

Donated $5 to FreeBSD Foundation
September 24th, 2014
I was feeling a bit down and wanted to spend money. But not too much money
either. Five dollars isn't gonna kill me. So I donated it to the FreeBSD
foundation. Go Open Source!
