I activated mars.centroid.eu (not on IPv6 yet). It took me a while to
boot the kernel on it because it has a broken cdrom, and my external
CDROM was not detected on it. So I had to netboot it. The experience
I'd like to document.
In /etc/dhcpd.conf-em5:
subnet 172.16.2.0 netmask 255.255.255.0 {
option routers 172.16.2.1;
range 172.16.2.240 172.16.2.254;
host mars {
hardware ethernet 00:30:65:a1:ec:a6;
fixed-address 172.16.2.2;
filename "ofwboot";
next-server 172.16.2.1;
option root-path "/tftpboot";
}
}
In /etc/inetd.conf:
172.16.2.1:tftp dgram udp wait root /usr/libexec/tftpd
tftpd -s /tftpboot
In /etc/exports:
/tftpboot 172.16.2.2
And then of course turn on portmap, nfsd, and mountd. kill -HUP inetd and
start dhcpd on em5. That did not boot it automatically but when you do a
set image bsd.rd in ofwboot on the macppc machine and then boot it should
boot into the kernel.
The boot command is: boot enet:,ofwboot /bsd.rd ...
It will first look up DHCP get the IP and then download ofwboot from the
TFTP server, it will then NFS mount /tftpboot and download the kernel
bsd.rd from there, from then on it'll boot normally into the install disk.

Profiling DNS answers
November 19th, 2011
Out of boredom I dumped the answers of A RR's for centroid.eu from my 3
different nameservers in production for that zone. I made pictures too.
In conclusion:
- BIND answers with the most data, it compresses the first answer with
C00C (compressed from the question).
- NSD3 answers with intermediate data, it doesn't compress the first name
in the answer section and is thus identifiable
- Wildcarddnsd serves as little answers as possible (this could change),
and it compresses the first name in the answer section (compressed from the
question)
Have a nice day!

chroot script for Bind 9.8.1-P1 and FreeBSD 7.4-STABLE
November 17th, 2011
I noticed that the install process on FreeBSD is different than the Makefile
provided with BIND 9.8.1-P1. So I made a script that you execute inside the
build directory of bind 9.8.1-P1. Make sure you only run this there, never
run this on / it will delete stuff out of the system!
#!/bin/sh
rm -rf usr/include/isccc
rm -rf usr/include/dns
rm -rf usr/include/dst
rm -rf usr/include/isccfg
rm -rf usr/include/bind9
rm -rf usr/include/lwres
rm -rf usr/share/man/man5
rm -rf usr/share/man/man8
rm -rf usr/share/man/man1
mkdir -p usr/local/sbin
mkdir -p usr/bin
mkdir -p usr/sbin
mkdir -p usr/lib
mkdir -p usr/libexec
mkdir -p usr/share/mk
mkdir -p libexec
mkdir -p lib
mkdir -p usr/include/isc
mkdir -p usr/local/share/man/man3
mkdir -p usr/share/man/man3
mkdir -p usr/share/man/man8
cp /usr/bin/make usr/bin/make
cp /usr/share/mk/* usr/share/mk/
cp /bin/sh bin/
cp /libexec/ld-elf.so.1 libexec
cp /libexec/ld-elf.so.1.old libexec
cp /libexec/ld-elf32.so.1 libexec
cp /libexec/ld-elf32.so.1.old libexec
cp /lib/libedit.so.6 lib
cp /lib/libncurses.so.7 lib
cp /lib/libncursesw.so.7 lib
cp /lib/libc.so.7 lib
cp /usr/bin/install usr/bin/
cp /bin/rm bin/
cp /bin/ln bin/
cp /usr/bin/sed usr/bin/
cp /bin/mkdir bin/
chroot `pwd` make install
Be sure to look this script over before you run it. It will install most
bind9 stuff under the "usr" directory which isn't existing in the bind9
directory. Cheers!

Donated 25 euros to Wikipedia
November 15th, 2011
Donation time is coming around again and I'm making more money as I have a
job this year so I thought I'd spend a little more. Here is a comment I was
able to put up for my money.
Thinking of donating to a few other projects now that I'm at it.

Rant on oil
November 12th, 2011
I'm worried about the human race. Ever since the great wars in the 1940's
we've been using gasoline and oil based fuels to power our economies. Our
economies pride themselves by having multiple trading partner, so as to not
be relied on one partner too much, yet we don't do this with transportation
means such as cars. People are lazy too. They will boycott buying gasoline
_for a day_ to make statements but it doesn't get any results. What we have
to do as a human race is to strip ourselves free of this dependency and create
a _mix_ of transportation means so that we don't fall into poverty when there
is no more oil. Guys ride your bikes more often! Mayors! Ban cars in cities
unless they are electric! We can't sleep on this or else we'll be poor as
we were in the beginning of the industrial revolution when the oil runs out.
Let's try to have 50% electric cars and 50% gasoline cars by 2020! I wager
that in 2022 the oil will run out if not sooner.

Upgraded Anti-Virus
November 11th, 2011
Today I bought Anti-virus for my Windows 7 vm. I was 1 day away from losing
my support and subscription so I bought it for this and 2 other PC's for
a years subscription. I believe all windows computers need anti-virus and
I even bought anti-virus for my dad's Mac. It's very important to keep
malware out.

Got a new VPS
November 7th, 2011
I got a new VPS. It's called io.solarscale.de.
I got this because goldflipper.net was down for 1.5 days and my DNS was hanging
on a string. The new host io doesn't do DNS just yet but it will in the next
few days. One bonus is that it does IPv6, and one drawback is that it's not
BSD. Oh well. I'll be comparing goldflipper.net and io for the next year and
a half and decide which one I will keep running. It's a matter of quality of
service.
$ host www.centroid.eu
www.centroid.eu has address 78.47.14.22
www.centroid.eu has address 200.46.208.61
www.centroid.eu has IPv6 address 2001:a60:f074:4::1
www.centroid.eu has IPv6 address 2a01:4f8:d13:1980::22
As you can see www.centroid.eu is DNS load shared between three hosts. io and
goldflipper for IPv4 and uranus and io for IPv6.

uranus upgraded
November 4th, 2011
I've upgraded my dear
box uranus to OpenBSD 5.0. Downtime was about one hour as I was upgrading
packages as well in single user mode. Some packages didn't want to be
upgraded, and I'll have to sort that out. Otherwise it worked like a
charm.
kern.version=OpenBSD 5.0 (GENERIC.MP) #59: Wed Aug 17 10:19:44 MDT 2011
deraadt@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC.MP
That's the version of the kernel running on it now.

OpenBSD 5.0 Released
November 1st, 2011
Well I was hoping to give you news of my CD's having arrived but they aren't
here yet. So I did an FTP of the install50.iso file for the amd64 architecture
and upgraded 2 vm's so far. I've made a screen shot:
Screenshot
Well as you can tell by the screenshot Libreoffice is in 5.0 instead of
OpenOffice. This is amazing! Also facebook stopped working for the 4.9
browser a few days ago. The browser bundled with OpenBSD 5.0 makes
facebook work again. Yay! Let's hope this will be as consistent and stable
as the 4.9 release. I'll be upgrading uranus.centroid.eu soonish.

7 Billion Humans
October 26th, 2011
Here
is a United Nations report that says we'll hit 7 Billion (estimate) Humans
in five days. I gotta say congratulations to the human race, but at the same
time I'm worried because in the 1970's we had just 4 Billion people on earth.
Here is the Universal
Declaration of Human Rights that SHOULD give every human, every one of
our 7 Billion, the rights that are the foundation of freedom, justice and
peace.
I have some issues with the large number of people like mentioned above, but
let me ask some questions. How are we going to feed everyone? Oil is running
out, how can we keep relative comforts for everyone? More fresh water is
polluted every day, how can we ensure drinking water for everyone? Machinery
is taking away humans work, how can we accept being unemployed because of it?
We realise we live on a planet in space, how can we ever accept that there is
other species elsewhere?
