How to Use Raspberry Pi as a VPN Gateway

A VPN (Virtual Private Network) protects your privacy by routing all your Internet traffic through an encrypted server that your ISP (or hackers) can’t see. Setting up and using a log-free VPN service from your PC desktop is straightforward enough, but other devices in your home such as your game console and set-top box don’t let you install VPN software.

One solution is to buy a router that can connect directly to a VPN service, protecting all the traffic on your home network a single stroke. But it could be cheaper (and simpler) just to route all your traffic through Raspberry Pi that remains connected to the VPN at all times.

With just a few fairly simple scripts, you can configure any Raspberry Pi to be a headless VPN gateway. This means that when it is connected to your router, you can send traffic to it from other devices before they connect to the outside world – essentially putting them behind a VPN. Read More

Build Your very own DNS server with a Raspberry Pi

In order for computers to communicate with each other over the internet, all participants in the network have a unique address: Through IP addresses, clients know exactly which servers they should address. But no user can be expected to memorize the numerical sequence of the address, so instead, domain names are used. For this, there’s a domain name system (DNS): It converts numbers into domains and vice versa. To do this, clients first have to query one or more DNS servers before they get the correct address. This can cost valuable time. Therefore, it can be useful to speed up the internet connection by setting up a dedicated DNS server. A Raspberry Pi, the small but many-sided computer, provides a good base for this. We explain to you here how DNS functions and how you can set up your own home DNS server.

Creating a Raspberry Pi cloud server with Owncloud

It’s becoming increasingly popular to use online storage with personal cloud providers such as Dropbox, Google Drive, or Amazon Drive. With these services, users can store their files in a cloud. This can be accessed at any time, using nothing more than a computer or mobile device with internet access.

However, it’s not uncommon for users to raise concerns regarding the reliability of their cloud hosting provider. A common criticism is that customers don’t know who else has access to the saved data, and whether the files are really removed from the server when they’re deleted. This is particularly important when it comes to the storage of sensitive data. If you want full control over your data, however, you can create and manage your own personal cloud.

ownCloud is a well-established, free, and easy-to-operate piece software developed for this purpose. The cost effective mini-computer, Raspberry Pi, acts as a particularly effective host for owncloud. This tutorial reveals everything you need to do to set up a Raspberry Pi cloud.Read More

Setup a File Sharing Server using Samba

Samba is the Linux implementation of the SMB/CIFS file sharing standard used by Windows PCs and Apple computers, and widely supported by media streamers, games consoles and mobile apps.

This tutorial assumes that you’ll use a keyboard, mouse, and monitor to set up your file server, but you can alternatively enable SSH and connect to it remotely from another computer on your local network.

We also assume you’re using a 32GB (or smaller) micro SD card, which provides a reasonable amount of storage space without requiring any extra steps to make it accessible. However, if you need extra storage, it’s easy to mount a large external USB drive and create a Samba entry for it.

Build a Stratum 1 NTP (Time) Server

The Raspberry Pi Model B was released in 2012 and, since then, a number of useful applications regarding this device have ensued. However, one particular application that is seldom overlooked when dealing with the Raspberry Pi is its ability to be used as a Stratum 1 NTP server and allow you to synchronize clocks across networks like the Internet. For me, this useful trick has actually made my entire office far more efficient.
