So… it was my 0×20′th birthday, and there was a party.

The pictures can be found below, thnx to all those who came around and had some drinks to celebrate.

Also thanks to Earle for taking the pictures, and bringing the weird Thai energy-drinks

I’ve decided that my PGP key could use some updating after 9 years. I have created a new (longer) and better-hashed PGP key. Now using 4096 bits of RSA, and using sha2 from now on

And the new key is:

pub 4096R/C4F69BD2 2009-05-11 [expires: 2019-05-09]
Key fingerprint = 6AFC 0D83 5346 C729 6754 113F D867 4D8F C4F6 9BD2

I have placed the key on my server: http://www.maniac.nl/maniac.gpg and uploaded it to the pgp keyserver(s).

I have also created a transition document, which is signed by my old and new keys, located on http://www.maniac.nl/key-transition.txt. If you have signed my old key (0×357D2178) please consider re-signing my new key after verifying the signatures on this document.

If you prefer to meet me face-to-face for a key verification, that shouldn’t be too hard to arrange. I’ll try to keep some keyslips on my at all times.

Update 2009/05/18: The file was signed first with my old key, and the result was signed with my new key. This gave some problems, and the file is now replaced by a new version which is signed by both keys simultaniously. This should verify correctly.

curl -s http://www.maniac.nl/key-transition.txt | gpg –verify
gpg: Signature made Mon 18 May 2009 11:00:17 AM CEST using RSA key ID C4F69BD2
gpg: Good signature from “Mark M. Janssen <maniac@maniac.nl>”
gpg: aka “[jpeg image of size 1522]”
gpg: Signature made Mon 18 May 2009 11:00:17 AM CEST using DSA key ID 357D2178
gpg: Good signature from “Mark Janssen (Maniac) <maniac@maniac.nl>”
gpg: aka “Mark Janssen <maniac@maniac.nl>”
gpg: aka “Mark Janssen <markj@markjanssen.nl>”
gpg: aka “[jpeg image of size 1522]”

I have also updated the old key to expire on 2009/12/31

Someone asked if there was a way for diff to only show lines that are the same between 2 files. A little digging in the manpage for gnu diff got me this nice result:

diff --unchanged-line-format=%L --old-line-format= --new-line-format= FILE1 FILE2


This seems to work… but i’m open to other suggestions

I gave a presentation about LDAP at this years Easterhegg in Hamburg.
The slides to the presentation can be found in the pentabarf system, or in this post:

I’m back from a weekend of Fosdem 2009, filled with Belgian beers, open source and meeting developers. I visited a few interesting talks and have some new items on my ‘Todo’ list now…

• Looking at Puppet and Cobbler
• Creating a LDAP presentation/workshop (to improve on what Geerd-Dietger Hoffmann did) for Easterhegg/Froscon/HAR2009.
• Work on LPI 301/302 exam prep.
• Improve my syslinux boot-anything usb-stick
• Study SELinux and AppArmor

During the last couple of weeks I’ve been working on getting a central directory setup for my client, running on OpenLDAP 2.4. Not having worked with LDAP a lot before it proved quite a challenge, especially getting Solaris 10 to work with the LDAP server without any glitches.
In this document I’ll try and describe how this setup was made, because I have been unable to find a single consistent document describing all the intricate details.
At this time I have all my problems fixed (AFAIK), but during the setup phase I experienced various problems:

• Solaris 10 not seeing any users from LDAP
• Solaris seeing users, but not letting them log in
• Log-in working from console, but not ssh
• Passwordless login (pubkey) not working in SUN-SSH
• Users being able to hack extra permissions for themselves
• etc…. etc….etc…

The entire article has been moved to a more permanent location, as a page on this site. You can find it under the ‘Pages’ header on the right. Setting up ldap

HAR2009, the four-yearly Dutch outdoor technology-conference has published the Call for Papers. I’ll include it verbatim here:

From the ancient days long before the first wayback-machine snapshot, hackers have a track record for appropriating technology that was meant for something completely different and putting it to alternative uses. And every four years since 1989, the international hacker community has descended upon The Netherlands in great numbers for a conference that focuses on contemporary and future issues surrounding technology and its social and political consequences. One reason that these conferences have been successful is the wide range of participants: from students, amateurs and aficionados to researchers, scientists and entrepreneurs who are recognized as some of the best in their respective fields.

Today I bought a new external USB harddrive, a MSI 320 GB, 4200 rpm 2.5″ disk. I removed it from it’s cabinet and replaced the 40GB disk from my PS3 with the 320 GB Fujitsu disk that came from the MSI case.

I expected the disk-upgrade for the PS3 to go quite easy, as I had already heard of some other people doing it, and many instruction pages and video’s online. I was however surprised by a message that popped up when I booted my PS3 after swapping the hard drive:

The system software cannot be run correctly. Press the PS button to try to restart the system.
If the system cannot be restarted, the system partition of the hard disk must be reformated and you must install the system software. Insert storage media that contains update data of version 2.30 or later, and then press the START and SELECT buttons at the same time.
For information on how to obtain update data, refer to the SCE web site for your region

After some searching I found the right update software and copied it tot a usb-stick and booted my PS3 again… still no luck.

After some more googling I found out that the update file “PS3UPDAT.PUP” needs to be placed in the /PS3/UPDATE directory on the usb-stick, or the PS3 won’t find it.

For EU playstations, you can get the update file here: http://uk.playstation.com/help-support/ps3/system-software/download/
For US playstations: http://www.us.playstation.com/Support/SystemUpdates/PS3

So now I’m waiting for the formatting to complete, and then I can restore my backup. Which will leave me with 280 Gigs of empty space to fill up with games, music and movies
