Xenserver/citrix hypervisor and xcp-ng blank screen while loading the installer

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 […]

Ubuntu 18.04 LTS kiosk for web or RDP

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 […]

Network configuration in Ubuntu Server 18.04

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 […]

Show online Teamspeak users without the client

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.

Deploy a Zabbix server to monitor your infrastructure

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 […]

MSSQL: keep your transaction log’s from exploding

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.

Citrix Xenserver and pfSense, slow traffic problems

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 […]

Add a local storage repository (SR) to Xenserver

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 […]

This theme (and how it came to be)

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 […]

First post (again)

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 […]
