If we were to run Raspberry Pi headless (without attached monitor), it would be nice if we can perform unattended system upgrades. In Debain/Ubuntu class of software, we can perform unattended upgrades using the software package unattended-upgrades.  To install the software, use the command below:  sudo apt-get install unattended-upgrades # Following are additional software required # we only need mailutils or bsd-mailx, choose 1 sudo apt-get install mailutils sudo apt-get install bsd-mailx sudo apt-get install update-notifier-common Next, we need to edit the configuration files: sudo nano /etc/apt/apt.conf.d/50unattended-upgrades The configuration should be similar as below: Unattended-Upgrade::Origins-Pattern { // Codename based matching: // This will follow the migration of a release through different // archives (e.g. from testing to stable and later oldstable). // "o=Debian,n=jessie"; // "o=Debian,n=jessie-update...

This is a supplement post on setting and configuring OpenVPN. However, we are going to configure OpenVPN on a Raspberry Pi. Download and Install Raspbian OS Download the latest Raspbian OS and burn the image to a SD card using the software Etcher. Once we booted up the Raspberry Pi, we can follow the wizard to set password, enable wifi and update the software. We can also choose to enable ssh and vnc using Raspberry Pi Configuration software. We can also run the configuration software from command line using raspi-config. Install OpenVPN and Easy-Rsa Once the system is updated, we can proceed to install OpenVPN using the command: sudo apt-get install -y openvpn The repository for Raspberry Pi do not have version 3 of easy-rsa. Version 3 of easy-rsa is more easier to use without the need to perform many configuration. To use Easy-RSA version 3, we can download the package from github at the location  https://github.com/OpenVPN/easy-rsa . Once we downloaded and u...

This is a simple guide on installing and configuring Raspbian for Raspberry Pi. Although Noobs is recommended for beginner, we find that downloading and transferring the image to SD card is much faster. Installing Raspbian First download the latest version of Raspbian from Raspberry Pi website . To transfer the image to SD card, we need to unzip the file first. We also need to prepare a SD card with an adapter for card reader or USB drive. Next we install and launch Etcher. This a free and open source tool to make bootable drive from Debian/Ubuntu based Linux. Select the image and drive and begin the transfer. Once it is done, insert the SD card into Pi and boot the system. During first boot we have addition configuration such as setting password etc. Once the setup is completed, please run update as follows: sudo apt-get update sudo apt-get upgrade Once the update is complete we are good to go.  Configuring Raspbian Raspbian is similar to other ...
