Remove evolution configuration settings

Posted by Treg in Linux, Tech

If you ever want to delete your entire Evolution account, history, configuration, settings, etc and start over from scratch, here’s how to do it:

Back up all of your files first (of course).
$ rm -rf ~/.evolution
$ rm -rf ~/.gconf/apps/evolution
$ evolution --force-shutdown

Find the process id for ‘gconfd’ and kill it:
$ ps -ef | grep gconfd
$ kill <pid>

Restart Evolution and you should be prompted to set up your acccount.

DE uitgaande (SMTP) mailserver lijst

Posted by Treg in Tech

Je kent het wel, je bent op locatie of in het buitenland en je zou graag een email versturen. Internet toegang op je laptop is geen probleem, maar je standaard uitgaande mailserver is (natuurlijk) niet bereikbaar vanaf deze “vreemde” ISP. Ziehier de oplossing, een lange lijst van mailservers van ISP’s over de hele wereld. Snel even de uitgaande mailserver wijzigen en je kan terug mailen. Handig!

Upgrade your Drupal websites

Posted by Treg in Tech

Since I’m maintaining a Drupal based website, I’m very interested in Drupal security issues. Last weeks, many attempts to hack the website (with injections, registrations and form abuse) have been made.

So, please upgrade your Drupal websites to version 5.11 or 6.5! More info can you find in this article SA-2008-060.

WordPress and Zend compatibility

Posted by Treg in Tech

Never ever try to install wordpress (> 2.1 I thought) on a machine (apache2 and php5.2) with “zend.ze1_compatibility_mode = On” in the php.ini settings. This setting will make apache2 childs crash. (I suppose there is something totaly wrong with the Zend lib)

Just adjust the setting to “zend.ze1_compatibility_mode = Off”

Linux kernel SATA bug solved.

Posted by Treg in HOWTO Ubuntu, Linux, Tech

Finally there’s a bugfix for the Linux kernel SATA bug I mentioned in this post. This is how I fixed it on my Ubuntu 7.04 machine:

– Make a file called stopsata in the folder /etc/init.d
The file should contain the following two rules:
echo 1 > /sys/class/scsi_disk/0\:0\:0\:0/stop_on_shutdown

– Make a file called S89stopsata in the folder /etc/rc0.d
The file is a symlink to the previously made script. You can link it with:
ln -s /etc/init.d/stopsata S89stopsata

Attention, Ubuntu 7.04 is using kernel 2.6.20.x. This fix is already included in the kernel but not standard activated yet.

Info/patch about the bug on

OpenVPN pkcs12 key conversion

Posted by Treg in HOWTO Ubuntu, Howto's, Linux, Tech

Since the latest network-manager-openvpn doens’t support pkcs12 certs, I needed to convert the pkcs12 key into other keys. This is how I managed to do it.

Extract CA cert, client cert and private key to a single PEM file
> openssl pkcs12 -in client.p12 -out client.pem

Extract client cert to client.cer (no private key or CA cert)
> openssl pkcs12 -in client.p12 -out client.crt -clcerts -nokeys

Extract client private key to client.key (no certs)
> openssl pkcs12 -in client.p12 -out client.key -nocerts

3ware/AMCC 8006-2 and Ubuntu Dapper Drake LTS 6.06

Posted by Treg in HOWTO Ubuntu, Linux, Tech

Lately I installed an Ubuntu Dapper LTS 6.06 server with a 3ware 8006-2 sata raid controller. I wanted to use the CLI and the 3DMD raidcontroller software. So I downloaded the software on the website, installed it, but it just refused to work, complaining about wrong drivers. I suppose the drivers into kernel 2.6.15.x are good enough, in fact they are _to_ good/new. So I started to find a solution. I found one by downloading the newest CLI version 9.4.1.

The 3DMD tool wouldn’t work either, so I tried to install the 3DM2 tool. It failed because the installer didn’t generate a .pem file. So I searched some repositories with 3DM2 binaries and found a debian based package.


I just had do install it with dpkg and it works perfectly now.

Linux Flash Player 9 Beta

Posted by Treg in Linux, Tech

Fortunately people decided to develop a new version of the Linux Flash player. On this moment version 7 ‘s the latest stable version. BUT, a few days ago version 9 beta has been released. Finally Linux users will be able to see all those Flash based sites and movies (which are nearly all made for flash 8 ).
You can find the player in the Sevaes Repo for Ubuntu Edgy Linux. The package ‘s also hard masked in Gentoo Portage (here).
