  • Experimenting with Icinga 2: a quick way to test an upgrade
    2015-06-24 09:30

    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?

    2014-11-25 10:27

    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.

  • Time Machine backups for Mac OSX 10.9 to a Debian GNU/Linux server on the network
    2014-08-24 18:23

    Disclaimer: I know absolutely nothing about Mac OSX, and my experiences so far have been pretty frustrating. So I wanted that a Mac laptop on my home network do its backups on a separate server.
