How to fix broken NX user authentication after OpenSSL fix

It looks like OpenSSH Keys generated on Debian derived distros (Ubuntu/Voyage etc.) are REALLY bad. I’m currently rolling out OpenSSL key updates as adviced on http://wiki.debian.org/SSLkeys.

One casualty of this update was my NX server using freenx. It just tells me that I can’t be authenticated. In the log /var/log/freenx.log it shows the following:

– NX SERVER START: -c /usr/lib/nx/nxserver - ORIG_COMMAND=
HELLO NXSERVER - Version 2.1.0-71 OS (GPL)
NX> 105 hello NXCLIENT - Version 2.1.0
NX> 134 Accepted protocol: 2.1.0
NX> 105 SET SHELL_MODE SHELL
NX> 105 SET AUTH_MODE PASSWORD
NX> 105 login
NX> 101 User: shuerlimann
NX> 102 Password:
NX> 404 ERROR: wrong password or login
NX> 999 Bye

This post talks about the NoMachine NX Server, but gave me the necessary clues: http://lists.kde.org/?l=freenx-knx&m=116542288527396&w=2

The magic command for freenx from http://datakeylive.com
on Ubuntu is

sudo rm /var/lib/nxserver/home/.ssh/known_hosts

This is necessary, as the SSH host key has been updated… Well, a more informative error message would’ve been nice, but I’m thankfull to the guys who produce freenx, anyway

Latest plan: Release 2 Kubuntu 8.04 CD’s: KDE 3.5 and KDE 4.0

According to this comment by Jucato Kubuntu 8.04 will be released in two variants: one with KDE 3.5 as default, the other with 4.0.

the plan is to release 2 Kubuntu 8.04 CD´s: one with KDE 3.5.8 (or .9) as default, and one with KDE 4 as default (but of course with some KDE 3 apps)

Working with plain ugly HTML

I’m currently doing some webdesign for the Shisha distributor we get our Al Fakher Shisha Tobacco for Agrabah. It started as a clone of the Al Fakher homepage. It’s just plain ugly HTML!!! I realy hate this copy’n'paste code after doing a good while of Ruby On Rails work… Even PHP is nicer…

Take part of the KDE relicensing effort

KDE needs a relicensing! While I’m not happy that the release of the GPL3 made such an effort necessary… But now it’s important to handle it fast and correct. Please give your feedback to techbase or use SVN:

svn co svn+ssh://$user@svn.kde.org/home/kde/trunk/KDE/kdesdk/scripts
vi scripts/relicensecheck.pl & add your name to all the four lists (that is if you agree to all four options)
svn ci scripts -m “I agree to a relicense”

As Tom Albers says:
“Really, it’s not more than a minute of work for you.”

Using KDE4 daily

I’m running KDE4 RC1 as my main desktop for 2 days now. Only few crashes, so productivity is good. But there are many small bugs. And it’s not very fast/responsive. But this is at least partially to blame on all the debug code.

Quite happy so far! It’s shaping up! Please test!!!

Packages from Kubuntu: HOWTO
KDE Four Live: openSUSE based Live CD
KDE4Daily: full virtual machine image with efficient update mechanism to SVN head

Please report any possibilities to try out KDE4 the easy way in the comments section

The promised HL7 update

Well, I’m multitasking heavily between project. I told you about my HL7 explorations. That project is on hold for a few weeks (due to my oscommerce setup for Agrabah and other projects). But here’s the link to some interesting opensource medical software: Elexis. It contains some HL7 importers and helps me a lot to see an actual implementation. Another helpfull source is the ruby-hl7 library. More later…

Get those mysterious osCommerce tools!

It’s simple! Install darcs (apt-get install darcs on Debian, Ubuntu etc.) and get the scripts:

darcs get http://code.cyt.ch/darcs/osc-tools/

This will create a osc-tools directory wherein there’s some smallish bash scripts. Documentation will follow…

osCommerce Tools available

I’m setting up an online store for oriental lifestyle products for Agrabah.

osCommerce is an opensource online store implementation. It’s implemented using PHP and there is a tonload of contributions available.

Most contributions are simple zip files containing additional or modified files. There’s a big problem when using multiple contributions modifying the same files. I’m using a distributed revision tool to merge those contributions. Here is the first release of some of the osc-tools

I’ll publish branches of those osCommerce contributions I’m using at the Agrabah Online Store.

Agrabah ist schuld!!!

Long time no post. Well, I blame it on Agrabah. It the small oriental store in the NeudorCenter in Cham, Switzerland I opened up with 2 friends. Don’t go to www.agrabah.ch for now. The site hasn’t been updated since the opening on 8.9.2009

You’ll see some more posts in the next few days. I intend to use this Blog to make notes about my diving into HL7 (Health Level 7). I got a small project going that includes reporting cytological data from the labors system into the doctors. Stay tuned for more opensource medical blog blobs…

Nice Rails plugin to support multiple databases

When working with more than one database, this plugin helps a lot for tests and connection setup.
