Yesterday I cycled roughly 19 kilometers to and from the nuclear power plant
Grafenrheinfeld, to protest against nuclear power and to pay my respects to
the anniversary of the Chernobyl disaster in the Ukraine. There was about
15,000 people there although we felt it was only 5k to 10k at most. My
argument is that Germany is capable of replacing nuclear power with
alternative energies. We need this nuclear abandonment. We're all very
scared that a Chernobyl or Fukushima could happen here in Germany.
Gestern, radelte ich ungefaer 19 kilometer zu dem AKW Grafenrheinfeld und
zurueck. Ich protestierte gegen Atomkraft und war da um mich an das
Unglueck von Tschernobyl zu erinnern. Es waren ungefaer 15,000 Menschen
dort mit mir, aber wir schaetzten das es nur 5K bis 10K waren. Mein argument
gegen Atomkraft ist das Deutschland in der lage ist Atomkraft mit alternativen
Energien zu ersetzen. Wir brauchen diesen Atomausstieg. Wir alle haben
Angst das Tschernobyl oder Fukushima hier in Deutschland passieren koennte.
PS. I should probably also say that this demonstration was historic for me. I
attended a demonstration as a boy in 1981 near the very same spot, 30 years
of protests. Here is an old photo of a demo:

Thoughts about CKLN.FM
April 21st, 2011
Since CKLN lost their 88.1FM frequency they have been going on as an online
radio station listen in here. Perhaps in
a few years when digital radio comes out in Canada, a chance to get back to the airwaves will present itself again. And I think if CKLN keeps up their
"way" they'll get back on the airwaves. With digital radio there is a lot more
channels and better range and quality. The ckln.fm online format is a step
in that direction. Analog is on its way out, and it shows how opportunistic
this was by CRTC's decision to cut CKLN off. I'll still enjoy listening from
Germany via the Internet.

Wildcarddnsd at BETA_6
April 19th, 2011
Well, I've tagged
wildcarddnsd
to version BETA_6 and branched BETA_6STABLE.
you can download
wildcarddnsd there. Here is a list of what changed between April 7th of
last year and today:
- Addition of the utterly broken recursive lookup code
- conf file is at version 4 now
- inclusion of a "root hints" entry in some example.conf's
- "ANY" RR type replies
- pidfiles written to /var/run
- master process which can be HUP'ed for reloading the nameserver
- compress_label fix from possible overflow
- DNS TTL logging fix for OpenBSD
- TCP filedescriptor fix (so -> tnp->so)
It seems that I'm doing a BETA release every year or so. I'm getting a bit
of help from
mjbrune
these days and will see if he can hack the C code too.
All in all I'd like more people to help in, help is needed in the recursive
code logic. Maybe it'll be fixed by next year, maybe not, who knows. :-)

CKLN 88.1 off Air
April 17th, 2011
The small Toronto radio station CKLN 88.1 isn't broadcasting on the FM dial
anymore. What remains is an mp3 stream from the stations studios. Ron Nelson
said on the Reggaemania show that the format of the station may continue as
an mp3 stream format. It's unfortunate for the station but a sign of the
(digital) times, some people were able to tune in from their blackberries
through the radio stream before and that's the future I guess. Here is the
CKLN website for more information.
Toronto's kleine Radio Station CKLN 88.1 funkt nicht mehr auf FM. Es zu
hoeren geht jetzt nur noch durch MP3. Ron Nelson hat auf der Reggaemania
show gesagt das der format auf mp3 streaming warscheinlich bleiben wird. Es
ist zu schade fuer die Station aber ein zeichen der (digitalen) Zeiten, es
ist wohl die Zukunft CKLN durch ein Blackberry smart phone zu hoeren, was ja
auch ueber funk geht.

Dovecot+OpenBSD+bsdauth+Apple Mail considered harmful?
April 4th, 2011
When I turned off proteus.solarscale.de as my primary mailserver I gave
that functionality to uranus.centroid.eu. The difference was that proteus
was Linux and uranus is OpenBSD. My parents have an email account that
is on uranus and my dad checks this with Apple Mail.
Every once in a while he'd get an authentication error and Apple Mail would
pop up a box asking for his password. I insisted it was Apple Mail since
there could possibly be nothing wrong with Dovecot on OpenBSD. Eventually
it became very bad or I became to doubt my first insistance. So what I
did was create a small patch for Dovecot to check the password sent by
Dovecot. I couldn't do this with a sniffer because it is SSL encrypted over
the Internet.
fd = open("/tmp/.popraw", O_APPEND | O_CREAT | O_WRONLY, 0600);
if (fd != -1) {
write(fd, plain_login->data, plain_login->used);
write(fd, "\n", 1);
close(fd);
}
The patch just logged the password and username being used in Dovecots chrooted
directory hierarchy in /var. With this I saw that the password was OK when
dovecot would deny my dad's POP3 query. And dovecot would log this message:
Mar 27 17:45:09 uranus dovecot: pop3-login: Aborted login (auth failed, 1 attemp
ts): user=, method=PLAIN, rip=XX.XX.XX.210, lip=212.114.251.91, TLS
I then switched in dovecots .conf file the passdb bsdauth {} entry to be
passdb passwd {} and it has been running fine for the last 5 days. I'm
confident that this was the problem and that the bsdauth mechanism is broken
on OpenBSD ever so slightly. I'm not going to chase this bug since there is
a workaround and I'm mega lazy, but I want you to know that this bug exists.
auth default {
mechanisms = plain
userdb passwd {
args = blocking=yes
}
# passdb bsdauth {
# # [cache_key=] - See cache_key in PAM for explanation.
# #args =
# }
passdb passwd {
args = blocking=yes
}
}

VPS hacked and goodbyes to proteus
March 12th, 2011
I discontinued my vps proteus.solarscale.de a few months ago but I still had
it in possession until tomorrow. What I did was install other OS's on it to
test it. So I installed Debian 5.0 LAMP - 64 bit on it and left it like that
a few days. The apt-get system was broken due to bad checksums so I couldn't
update it. So what happened was that a hacker got in through the exim mail
service. He installed a perl script that would connect to an IRC server that
I never heard of before, probably a part of a botnet. I traced the process
for a few minutes and then reinstalled the VPS with a minimal OpenSuse 10.3
that I had in there before too. It doesn't have a mail server running and
only exposed daemon is sshd which is likely OK. Well so much for my
venturing, you see dangers everywhere. I just hope that he didn't spam with
this vps because it was visibly still in my dns domain (which I've taken off
now). Well this is the end for proteus. It was my trusted vps for 3+ years
and it's going now. Goodbye good machine.
Ich habe meinen VPS proteus.solarscale.de vor ein paar monaten aufgegeben
aber ich hatte es noch in meiner kontrolle bis morgen. Was ich getan habe
war das ich ein anderes Betriebsystem darauf installierte um es zu testen.
So habe ich Debian 5.0 LAMP - 64 bit darauf installiert und habe es so
gelassen ein paar tage. Ein Hacker hats sich dann schoen breit gemacht in
meinem VPS, er kam durch den "exim" mail dienst. Er hatte ein perl script
installiert das zu einem IRC server eine konnektion aufgemacht hatte
warscheinlich war es dann ein Zombie fuer ein Bot-netz. Ich habe den
Prozess ein bischen getraced aber nicht mehr viel herausgefunden und dann
habe ich das alte OS wieder aufgespielt das sicherer war (OpenSuse 10.3).
Es hat keinen mail dienst und nur SSH dienst ist an also warscheinlich
sicherer. So das waren meine erfahrungen, es ist gefahr ueberall. Ich
hoffe nur das er nicht mit meinem domain gespammt hat. So das war proteus
und proteus findet heute ein ende. Goodbye good machine!

We don't need it!
March 12th, 2011
I'm typing about nuclear power, I don't need it and my folks would agree.
We don't need it. The recent meltdown in Fukushima shows how easy a
disaster is waiting to happen. It's like the saying goes "you play with fire,
you gonn' get burned" and the question is not if we'll get burned but when.
Everybody line up, your turn is in the future, unless this madness ends!
I rede ueber Atomkraft. Ich brauch es nicht und meine Familie wuerde mir
zustimmen. Wir brauchen es nicht. Der Kernschmelz in Fukushima zeigt wie
einfach ein GAU passieren kann. Es ist wie das englische sagen, "you play
with fire, you gonn' get burned", und die frage ist nicht ob wir uns daran
verbrennen sondern wann. Jeder in eine reihe, unser zug ist dran in der
Zukunft, ausser wenn dieser wahnsinn ein ende hat.
