• Basic Networking and FreeBSD


    In this article I would like to introduce the very basics of networking in order to allow the reader to be able to separate VMs from each other or to organize them into logically different segments. This is far from a detailed description of networks, of course!

  • ZFS Host Spare with ZFSd


    Since FreeBSD 11.0 was released, it’s been possible to use a disk as a hot spare in a ZFS zpool. This means, that under a few circumstances, zfsd will take a predefined disk to replace another one.

  • Installing Civilization V On Arch Linux


    I’m not really a gamer myself, but as it turned out, my wife is. She played with Civilization V many years ago on Windows, and wanted to re-play the game now. However, I have successfully eliminated it from everywhere in the household, we run Linux on the desktops and FreeBSD on the “servers”, so we seemed to have a slight problem: how to let the wife play without installing anything Windows?

  • Using LLDP on FreeBSD


    LLDP, or Link Layer Discovery Protocol allows system administrators to easily map the network, eliminating the need to physically run the cables in a rack. LLDP is a protocol used to send and receive information about a neighboring device connected directly to a networking interface. It is similar to Cisco’s CDP, Foundry’s FDP, Nortel’s SONMP, etc. It is a stateless protocol, meaning that an LLDP-enabled device sends advertisements even if the other side cannot do anything with it. In this guide the installation and configuration of the LLDP daemon on FreeBSD as well as on a Cisco switch will be introduced.

  • Cisco Virtual Wireless LAN Controller on FreeBSD bhyve


    In this guide a Cisco vWLC will be installed on FreeBSD bhyve. Altough the Cisco Virtual Wireless LAN Controller (vWLC) is officially supported only on VMWare ESXi, Linux KVM and Microsoft Hyper-V, it is relatively easy to install and operate on FreeBSD bhyve. The installation is actually pretty similar to KVM.

  • Using letsencrypt.sh with h2o


    This will be a really short guide about how to set up the H2O webserver with letsencrypt, and how to automate it. I’ve read a nice tutorial about letsencrypt and nginx on Peter Wemm’s site. This guide is similar, but for an h2o webserver. I intend to write another guide about www/h2o later once v2.0 is released, this is just a short tutorial about letsencrypt.

  • Booting FreeBSD on a Raspberry Pi Zero


    Luckily, I was able to get a Raspberry Pi Zero not so long ago. Naturally, my first move was to try to boot FreeBSD on it. Although there is no official support for the Zero on FreeBSD, given that the hardware is very similar to the Raspberry Pi A model, I was able to boot it. The process is quite simple.

  • Using bhyve on FreeBSD


    I wanted to write an article about bhyve for a long time now, and fortunately I recently had the time to do just that. Bhyve has the potential to became a very sophisticated, and advanced hypervisor.

  • Hello World!


    I have decided to create a blog. My main goal is to write articles and guides about various topics, like Cisco Networking, FreeBSD and Linux. This blog is powered by jekyll, and is completly javascript and flash free. There are no cookies, and no Analytics either. Just the pure content. I use the most minimalistic theme possible, focusing of the contents of the posts. This blog is also easily readable with a command line browser too, like lynx.
