Firmware happiness

Firmware happiness

I am quite used to install operating system updates on deb and rpm based Linux distros. This is usually a simple update && upgrade. But firmware updates on Linux is a pain in the ass, until now I discovered recently on my new laptop [https://vleeuwen.net/linux-pre-installed-laptop/]. Thanks

Linux pre-installed laptop

Linux pre-installed laptop

Yesterday I received my first laptop which had Ubuntu pre-installed. It is a Dell XPS 13 developer edition (7390). The idea is to replace the large workstation under the desk with this system to be more flexible at the workplace. It was a really nice first impression to see most

Goodbye OSX, hello Ubuntu!

Goodbye OSX, hello Ubuntu!

Because of some features in the latest stable XBMC release I felt the urge to upgrade my XBMC install from 12.3 to the latest stable version. Somewhere I have read XBMC 13 “Gotham” had dropped support for OSX 10.6, so I decided to migrate to Ubuntu, because my

Create a persistent Debian Live USB Flash Drive

For a hobby project I have recently build a new computer system. This system is setup only for mining altcoins using three ATI Radeon 7950 graphics cards. I decided to make use of an unused USB Flash Drive for two reasons. Because it is cheap and less power hungry then

VOIP problemo

Today I encountered a strange problem when I tried making a phone call using my home VOIP telephone. I could dial out, but there was no sound coming through, which is pretty confusing. At first I thought it had something to do with the firmware update I did recently on

Rootless SCOM agent setup

The setup of a SCOM agent without having to enter the root password in the SCOM management console is actually very simple. At first I thought it would be necessary to export the key by which the client certificates are signed to do the signing on the system used to

Manual SCOM agent certificate signing

The SCOM server communicates with the agent running on port 1270/tcp. Normally you will deploy the agent by using the discovery

Install SCOM agent on Red Hat Linux

The steps below describe how to install the SCOM agent on Red Hat Linux 5 x64. We don’t like to enroll the agent by using the SCOM Discovery wizard, as you need to enter the super-user (root)credentials and we’re not sure where the application stores those credentials

License to rdesktop

Today I recieved a strange message when I tried to open a RDP connection. $ rdesktop windows.server.local Autoselected keyboard map en-us disconnect: No valid license available. To resolve this issue you need to add the client hostname. $ rdesktop -n hostname windows.server.local Autoselected keyboard map en-us WARNING: Remote

WP add media problem

When using WordPress version 2.5.1 (Debian Lenny package) it is not possible to add/upload media using the “Add media” button in the editor. If you click on Add an image, a new window appears where you should have the option buttons “Browse” and “Upload”, but they’re

Home phone by Asterisk

Last week I’ve spend some time doing an Asterisk [http://www.asterisk.org/] PBX setup at home. Because I like the technique and my girlfriend likes to use the phone I decided to build my own PBX (Private Branch Exchange). In other words a telephone exchange. So doing some

eToken, Personal certificate and the Mozilla suite

Recently I have a personal certificate also known as a Digital ID on a smart card (Aladdin eToken) to access a secure web service. While installing the certificate I noticed it is also possible to use it to digitally sign and encrypt email with the same certificate, so I fired

eToken and Linux

To make the eToken PKI 5.0 client work on my 64bit Fedora 11 workstation with the 32bit version of the Aladdin eToken middle ware I had to install the following packages: hal-libs.i586, libusb.i586, openct.i586, pcsc-lite-openct.i586, pcsc-lite-libs.i586, pcsc-lite.i586 and dependencies. rpm -ivh pkiclient-5.00.

Wireless fix on Amilo running Ubuntu

Recently I had to use a laptop for a course I was doing. This Fujisu Siemens Amilo Li 2727 laptop came with Windows Vista pre-installed. Since the installed OS didn’t matter for the course I installed the latest Ubuntu which is 9.04 (Jaunty). All worked well except for

Gallery2 and Lenny

During the upgrade from Etch to Lenny I was surprised that the Gallery2 package was not available for the current stable release of Debian. At first it was no problem, but the Gallery2 package of old stable Etch is to old for the most recent WPG2 plug-in for WordPress, so

Persistent route in Fedora

Today I had to add a static-route on a Fedora 10 workstation to gain access to a web application. Because it needs to be persistent, survive reboots, I wanted to configure the static-route the way Fedora (Red Hat) likes it. The script ‘/etc/sysconfig/network-scripts/ifup-routes’ is responsible for setting

Enlarging the size of a striped LV

Since there were not enough free PPs available within the VG to extend our fast growing LV we had to increase disk space and extend this LV, but this was a little different from the usual manner because of this LV was a striped one. At first we thought we

PE1950 installation hassle

Installing debian etch (40r4a) on a Dell PowerEdege 1950 with SAS disks was not to easy. Debian crashed the fist reboot after the install, because of not loading or finding the correct module in initrd. The second issuse was swaping the drive from sdb to sda. This is how I
