How to set up a PPTP VPN server on Ubuntu

Nowadays free public WiFi networks are available in many areas, for example in airports, restaurants or public transportation. A major disadvantage of a public WiFi network is security. You can’t be sure no one stealing sensitive data by eavesdropping the connections. A solution is to setup a secure/encrypted channel to a Virtual Private Network (VPN). When using a VPN and you connect to for instance your webmail, the data is sent via the VPN. In this post I’ll describe how to set up a PPTP VPN server on Ubuntu. Using PPTP you can not only connect your laptop, but also your Android or iOS (iPhone or iPad) devices.

Building a Home Theater PC part 2

Today I finally assembled my HTPC. There were some stock issues with the case I ordered, so after a week I ordered another. Although the motherboard is passively cooled I decided to enable one of the two case fans. Unfortunately the fans are very noisy when directly connected to the motherboard, so I placed a simple Zalman fancontroller between the fan and motherboard.

After building the HTPC I first installed Ubuntu 10.10 using a USB stick. Then I used this guide to install XBMC.

Building a Home Theater PC part 1

Last year I build a home server based on the Intel Atom platform. In my second post I mentioned building an HTPC with the same components, but I wasn’t really sure the current Atom processors and Nvidia ION platform could handle video decoding with a full HD resolution. Since a few weeks I’m looking for information how to build an HTPC running XBMC based on the latest Atom processors with Nvidia ION 2. I found this blog and I think I will use more or less the same parts because it’s a very good price/value solution.

Building a home server part 1

I recently decided to build my own Ubuntu home server with the following requirements:

  • Low energy consumptionUbuntu server
  • Small
  • Noiseless

A friend of mine recommended the Asus EEE Box. However, this machine was released a year ago and the price didn’t drop much. And besides, Intel recently released the new Atom generation. Therefore I decided to build my own machine with the following components:

Recover Windows XP on Samsung NC10

A few weeks ago my virus software removed a .sys file because it was ‘infected’ with a virus. As a result my Windows XP didn’t boot anymore, even in safe mode. Since it was time for a fresh Windows XP install I tried to start the recovery cd using an USB CD-ROM player. Apparently the recovery cd wasn’t bootable. Luckily Samsung had another option; pressing F4 in the bios startup screen. This didn’t work either since I used Grub to choose between Windows XP and Ubuntu.
