While performing maintenance on my lab environment i encounterd a strange problem with the installation process for Xenserver 8.2 (and 8.1/8.0). Starting the installer will result in ether a black screen or a kernel panic. After some research i found an interesting issue in github (from the xcp-ng project) https://github.com/xcp-ng/xcp/issues/206. It remains unclear why the […]
I remember when I booted Windows Vista for the first time, there where three things that stood out at the time: Actual working 64 bit support, which was useful for virtualization (yes, i know about XP x64. And no, it does not count). The new color scheme. lets face it, it was quite refreshing after […]
In this article we will show how to setup a browser or RDP kiosk, based on Ubuntu server 18.04 LTS. Because we are using the server edition the kiosk system will have a very small footprint and way less packets installed when we compare it to a stripped down desktop kiosk. First we need to […]
As you might have heard, Ubuntu (server) 18.04 uses a new network configuration system named Netplan. Well, Netplan is not entirely new, it was introduced in Ubuntu 17:10 but I did not pay to much attention to it at the time because I prefer the Ubuntu LTS editions. The first big change you will notice […]
It might sound like a useless project, but I wanted to be able to check who was using my Teamspeak server without having to be logged on all the time. After a short search over the world wide web, I came across the “Powerful PHP Framework” from planet teamspreak. This framework enables the user to […]
If you maintain a ICT infrastructure you probably use (or your looking to use) a monitoring solution to monitor your ICT infrastructure. Detecting, and fixing, problems before end users start experiencing them is something most ICT professionals love to accomplish, preferably every time a problem occurs. Zabbix is an open-source monitoring solution for servers, network […]
I recently discovered that my employers database server was running out of storage space on the database volume. After some searching I traced the problem to our Xendesktop site transaction log file witch had grown almost 80GB in 3 months. I never noticed problems with the transaction logs before but previously the SQL server was […]
After setting up the delivery controller and configuring storefront to allow the HTML5 Receiver it is finally time to add a desktop to the mix. In this step by step article we will be adding a single desktop in “remote PC access mode”. this means that XenDesktop wont power manage the desktop and we wont […]
In the first part of this series of articles about Xendesktop, we have installed a delivery controller and configured a empty site. In part 2 we will be configuring Citrix Storefront for use with the Receiver for web application and we will setup the necessary policy’s. This will greatly improve the enviroment for testing purposes […]
Citrix Xendesktop is the remote desktop solution from Citrix. Since version 7 it is completely integrated with Xenapp, the terminal server like solution from Citrix. Together these solutions are capable to overcome (almost) every workplace virtualization challenge. I have not updated my home lab enviroment in a long time, it was still running Xenapp 7.5. […]
A while back, I added a pfSense installation to my home lab environment. pfSense is a opensource network firewall/router operating system which offers a large amount of additional (3e party) modules to extend its functionality such as OpenVPN, Snort, etc. At this time, I am mainly interested in the OpenVPN functionality and I would very […]
Recently i added a new SSD to my home lab hypervisor. Xenserver does not detect new disks by default, so I had to add the drive manual, luckily this is not a complicated process (some command line experience is required). First we need to find the device name of the new drive, for this we […]

Today I can tell you one of Microsoft’s competitors has made the same move, and its not Google. LibreOffice is well known for its open source and free office solution unfortunately LibreOffice always needed […]

Whether you are trying to keep track of time, tasks or inventory, Kanban is a good way to go. Kanban was was originally designed as a inventory […]
After about 2.5 years of not having a blog I thought it was time to give it another try. My last blogging attempt failed because I did not have the time to post something interesting from time to time. The blog itself also looked horribly bad with a black theme and orange accents it was […]
At work, we have a number of servers which use the default windows software RAID implementation to insure OS disk redundancy (RAID 1). whether Software RAID 1 is a good solution for the situation is debatable, but this is not part of the scope for this article. One Thursday morning I noticed one of the […]
After 2.5 years I’m back with a new blog, and its not black and orange (progress people!). Seriously, after a long period of not having/making the time to write about day to day ICT problems (and solutions) and private projects, I’m back. This blog will (just like the last one) contain a combination of installation/configuration […]
