The solstice is here in in less than a week! You can read about
Solstices here. I
predict if daylight is the same X days before and after the solstice in
symmetric fashion then the days should be getting longer on the 28th of
December which isn't too far off! At least this applies to the northern
hemisphere! And inbetween is christmas, so it's not so bad is it?

io <--> americas <--> moon now IPSEC'ed
December 12th, 2013
I have made 2 IPSEC tunnels between io.solarscale.de, americas.centroid.eu
and moon.virgostar.net. These are all my 3 nameservers and they used to
exchange zone files in plain text. Well not no more.
IO and MOON are FreeBSD so I found racoon the right combination for them.
Americas which is OpenBSD uses isakmpd all for IKEv1 key exchange. The
cipher negotiated is AES. It seems to work and I packet dumped to confirm
that it's ESP'ed. Praise!

Wildcarddnsd is in production again
December 8th, 2013
After a long pause of more than a year, I've enabled wildcarddnsd on
americas.centroid.eu. It is master to a bind9 (moon.virgostar.net) and an
nsd3 (io.solarscale.de) nameserver. I was able to do this change due to
wildcarddnsd's shared memory which didn't work on a freebsd jail.
Anyhow I only did a few mistakes moving the zones over and perhaps I should
write a bind9 zones convert tool to wildcarddnsd zones.

Merkle's puzzles not to defeat
December 4th, 2013
But to stall/delay/cost the adversary..
On chapter 2, page 34 of Applied Cryptography by Bruce Schneier, which is a
rather old text I found the gem of Merkle's puzzles. Ralph Merkle is renowned
in the cryptography scene for finding out about these puzzles. While I don't
want to go into explaining the puzzle, I do think that they can offer some
protection when RSA assymetric encryption fails. Pretend there is a quantum
computer able to break assymetric encryption. What I have done is implemented
a Merkle's puzzle server that I'll be using to connect to my vps. The server
creates a tunnel that is SHA1 HMAC'ed and AES-256-CBC encrypted. While this
may seem enough, it's not. I still ssh within this tunnel but it does require
some effort to get to the assymetric encryption.
jupiter$ ls -1 *.c
mps.c - creates the gigabytefile of encrypted messages
mpsclient.c - uses a cracked message to talk to the server
mpscrack.c - cracks a message in the gigabyte file
mpsd.c - talks to the client to set up the encrypted tunnel
I'll be setting up a system to distribute over ssh the gigabytefile so that I
can crack a message at home with it and from there use mpsclient to connect
to the server.
I'm debating whether I should open source this. Give it time perhaps I will.

Americas is now OpenBSD
December 3rd, 2013
I have taken the new americas into "production" so to speak. It is serving
all kinds of things and I'm currently developing software to make it even
"safer" :-).

Wildcarddnsd BETA 8 has been released
November 19th, 2013
This is a small release for wildcarddnsd. We have new debug feature and support for Raspberry Pi. It is a small
release because I have dwindling time this year due to my job and there is
little to no help coming from the outside. I welcome each and every person who
wants to program on this daemon.

Sent Brad Smith 10 Euros
November 18th, 2013
A call on the
undeadly openbsd journal was answered by me. I sent Brad Smith 10 euros
for his new laptop. If 100 people do similar he'll be able to buy his new
beast. Of course this is for the greater good! Brad lives in Toronto where
I used to live for 7 years once, so this is from one (ex-)Torontonian to the next.

My first OpenBSD vps
November 17th, 2013
I have decided to switch plans on my Panama VPS americas.centroid.eu. I now
have the option to run OpenBSD on it and I'm going to go for it.
I'm looking forward to IPSEC encrypting from io.solarscale.de and moon.virgostar.net to americas.centroid.eu. I have already set up strongswan on io and moon
and americas was lacking this functionality but now it'll work. This should
keep me busy until new years :-).

Ordered a new book
November 15th, 2013
I have ordered...
- Alternative DNS Servers: Choice and Deployment, and Optional SQL/LDAP Back-Ends - Jan-Piet Mens
I do hope this is worth having. This brings my orders for this year to 15
which I hoped to achieve, perhaps I'll order one or two more books but then
that's it. I gotta read these too!
