Microsoft Exchange is one of the most used mail server and calendaring system in the world. Although new kind of communication and collaboration sofwares are cutting into this space, e-mails remain a vital communication tool for many businesses. In this tutorial I will show you how to install and setup the latest version of Exchange. This tutorial will be split into 2 parts. Part 1 is about the installation and Part2 is about the setup and configuration.

Reverse Proxy with Nginx

Often when there are multiple servers behind one single public IP (WAN), people tend to use NAT / Port Forwarding to get to the target server behind the public IP. For example if you have multiple webservers behind a Public IP, you have to setup your Firewall to listen to different ports then forward those ports to the correct internal IP-addresses. With Reverse Proxy you can use URLs to forward to the correct internal servers:

Pfsense firewall part 2 – installation

In Part1  I wrote about the search for the right box to which the Pfsense will be  installed on. In this part I’ll go through the installation process of the Pfsense software on the Zotac box. 1 Download the PFsense software – image The Pfsense software…

Pfsense firewall part 1 – the box

A few years ago I installed Tomato router firmware on my Netgear WNR 3500l v2 router. The goal was to get more advanced features out of a consumer-grade router, for example like adding virtual WLANs and VLANs. It was a success and the router is still…

The Pale Blue Dot – Carl Sagan

Sometimes words encourage you to think and to look beyond the everyday life – to understand that we are just but a nuance in the vast cosmic arena. They make you feel humble yet not any less hungry to understand more of our world and universe.

Human Population part 2

“Anyone who believes indefinite growth in anything physical on a physically finite planet is either mad or an economist” – Kenneth E. Boulding.

I recently stumbled upon a youtube clip where Sir David Attenborough eloquently talked about the issue of the growing human population. About six years ago I also wrote about this very same issue. It’s one thing to read something from a person like me, but it’s a total different thing to listen to a knowledgeable and highly intellectual person like Sir David Attenborough. In this clip Sir David touched on many issues regarding the fundamental causes, consequences and solutions to this alarming problem.

How to add a virtual WLAN with Tomato firmware

In my earlier post Netgear WNR 3500l v2 with Tomato firmware, I wrote how to install a third party firmware calls Tomato on the Netgear 3500l v2 router. Tomato firmware enables many features that often are missing in the stock firmware. One of the feature that I think is pretty awesome is the ability to create a virtual WLAN. A virtual WLAN is also often being called as “Guest WLAN” on many new and advanced routers. Usually it is a feature that you just turn on and magically you get a new WLAN (SSID) that your guests can you use.

ManageEngine ServiceDesk Plus Standard

One of the basic but also the most important services an IT-department has is the helpdesk. From my experience many IT-departments use (bare) e-mail as the helpdesk system. E-mail does work to some extends, but comes short when you want to have a good overview of the incidents. Often it is hard to know which incident has assigned to which technician and what the technician has done in the life of that incident.
