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.
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.
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.
On my server I want to create accounts that can do SSH in a chroot environment. On the internet I searched for tools and I found Jailkit. In this post I will tell how I installed Jailkit on Ubuntu server 9.10, created a jail and how users are added to the jail. Note that most commands in this tutorial should be executed as su or sudo.
First I installed Jailkit by using the following commands:
# cd /tmp
# wget http://olivier.sessink.nl/jailkit/jailkit-2.11.tar.gz
# tar -zxvf jailkit-2.11.tar.gz
# cd jailkit-2.11
# make install
I recently decided to build my own Ubuntu home server with the following requirements:
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:
