Why should I dare to launch the VirtualBox GUI each and every time when I in fact only want to start a particular VM?
So my intent is to create an icon in the OS X dock which allows me to start my Windows VM directly with one single click.
Not to say that I’m a lazy person, but I dare to get around the GUI for such a simple and straight forward task 😉

Luckily VirtualBox provides us with everything needed to accomplish this through the “VBoxManage” command.
The rest is just some (not so really) magic OS X trickery, as you’ll find out shortly.

So you finally own one of these newly released Apple MacBook Pro with fancy Core i7 Quad-Core CPU?
Then you fire up your VirtualBox VM and are disappointed about the sloppy performance?

Luckily, it’s only a (hopefully short-lived) compatility issue. While this will surely need a final fix, here’s a temporary workaround…

I always used to have Windows installed through Boot Camp on my MacBook Pro. The reason for it being simple: I need it for some games 😉
On the other hand, I use OS X for my primary work, but again, sometimes there’s no way around Windows. So I had the same Windows installed again within VirtualBox.

Well, what a waste of valuable disk space. So, after I got my new MacBook Pro, equipped with an SSD, I decided to go for it and share the Boot Camp partition between Windows 7 running natively and VirtualBox.

Ganz den üblichen Gepflogenheiten dieses Blogs zum Trotz wird dieser Beitrag ausnahmsweise in Deutsch abgefasst, dies aus der Überlegung heraus, dass hier ein “lokales” Interesse überwiegen dürfte.

Im Rahmen eines Freundschaftsdienstes habe ich CEYA Beaty & Wellnes SPA bei der Installation der greenCube Business Software in einer Client-Server-Umgebung unterstützt.

Eigentlich würde ich auch mal eine kurze Anleitung für die Client-Server-Installation verfassen, da die offizielle Anleitung in meinen Augen doch etwas dürftig ausgefallen ist. Aber da “man” wohl auch seine Support-Dienstleistungen an den Mann bringen möchte, wäre das wohl ein wenig zu sehr im fremden Revier gewildert, oder? 😉

Hier geht’s nun allerdings erstmal um einen recht spezifischen Fehler, der bei der Client-Installation unter Windows Vista aufgetreten ist.

Currently playing around with my Netra T1 105 and a Sun StorEdge Multipack enclosure, I wondered if I really could add the whole enclosure while the host is online.

I used to do hot-plugging before, but I’ve never done this with a whole enclosure at once. Well worth a try?

DOS never dies! So don’t the boot floppies 😉

I have these since years and made them ready for web-download in 2001 already.
Now I gathered them back from my archives to put them aside to download at phunsites.net.

Maybe, these are of use to others to.

Thinking about FreeBSD jails and an elder post of mine about putting jails within loopback-mounted disk images to enforce disk quota, I asked myself if I should use sparse files or pre-allocated files as virtual disk image for jail-based userland separation.

There’s maybe a zillion computer issues out there which are so damn weird that most people scratch their head in misbelief.
One of these weirdnesses just crossed my way a few days ago.

It all started with a very simple task: One of my engineers had to renew an SSL certificate for an IIS-hosted website.
After receiving the renewed SSL certificate and importing it into the certificate store, he tried to bind the SSL port on the IIS website with the new certificate.

What a bummer when he discovered, that this would always result in the following error, no matter what and how often he tried:

As you came along I suppose you stubled accross the same issue as me, didn’t you?

As far as I’m concerned, I can only tell that this issue rises when netbooting Debian-Installer through PXE/TFTP in combination with a preseed.cfg file, while the latter one being downloaded from a HTTP web-server.
This bevahiour has been observed with Debian Lenny and older versions and can cause quiet some headache upon setup automation if not taken into account.

Today I faced a very issue with Apache 2.2 in FreeBSD.

Despite having it compiled with IPV6 support enabled, it pretended in missing IPv6 support, throwing this error message at me.
