    A few clients received the following e-mail [...]. The screenshot included a listing of the root directory of the website, which had one non-standard directory specific to the client, so it was a rather good hint that he had access to privileged information. I am always skeptic of such emails, usually scams, borderline extortion, but in any case the screenshot did provide sufficient proof to investigate.

    Icinga 2 which was initially released around July 2014. Icinga is a fork of the Nagios monitoring system, meaning that it can do periodic checks to servers, services and networks to make sure everything is running smoothly. If not, it can e-mail, text or phone a system administrator.

    Staying close to Nagios syntax had its comforts, but it also meant keeping some of its limitations. Icinga 2 is more of a complete rewrite. The documentation keeps talking about node communication with SSL and a 12 step program to get started... with nodes. What if you just want to convert your Icinga 1 configuration and see how it goes?

    Context: I was running Virtual Box on my desktop for a mix of Windows testing VMs (for Internet Explorer) and GNU/Linux test servers for development. However, I also kind of like the idea of running some services from home, since not everything needs to be in a datacenter. My home Internet is reliable enough and connected to the local Montreal mesh network. I also like the idea of mirroring virtual machines that I host in a data center locally, and vice-versa, meaning that using ZFS snapshots that are backed-up nightly, I could re-spawn a VM in another location pretty quickly.
