Recently I’ve been working on several new projects, all of which use either a Raspberry Pi or an Arduino.

Site-To-Site VPN

A friend of mine recently opened a new satellite office, and as part of his day to day work had a requirement to connect the two together so resources on either side could see each other. Site-to-site VPN I thought, and what better kit for the task than a couple of Raspberry Pi’s. Nice and small so they can be kept along side the routers. Each site had a simple ADSL broadband link, with a couple of PC’s connecting up.

Here’s a (very) quick howto showing how to get GlusterFS up and running on Fedora. Its probably better situated on a distro like CentOS/RHEL, Ubuntu Server LTS or Debian stable but where’s the fun in knowing it won’t break? Most of these commands are transferrable to other distros though, its Fedora centric due to the use of yum, selinux and systemd (systemctl).

Pre-requisites: 2x (or more) servers running Fedora, I used 18 in this example but i’m sure it shouldn’t change a great deal for newer releases. If it does I’ll try update this doc. The idea behind this setup is to use 2 servers as hypervisors (KVM) and have local storage but reslience, I won’t be covering the virtualisation side, purely storage so VM’s will be adequate for this setup.
