I have previously described how to create a virtual machine using bhyve. There is, however, a nice utility that allows for a level of simplification. It is called vm-bhyve. In this case i will get into installing ubuntu 16.4 LTS as a virtual machine, with 16GB of ram and a 500GB drive. Installation The installation…

Virtualization with bhyve
After looking at Virtual Box to setup virtual servers i decided to have a look at bhyve as well. A good thing about it is that it is native of the *BSD family. I will go through two set of installation of a Ubuntu Linux (in my case 20.4 LTS). The first is straight with…
Running Virtual Box on a FreeBSD Host
While I have been using Jails (a built in capability of FreeBSD) to obtain some of the functionalities of virtualization (and I love the simplicity and well as the low memory and hardware footprint that come with this solution) there are cases in which an actual virtualization is preferred or required. Virtual Box might be…
Bind – DNSSEC
DNSSEC is basically a way to verify the authenticity of DNS information. You can read more about it in the DNSSEC wikipedia page. I’m simply going to address how to properly configure it. We start from a working Bind installation and some zone files. The process that we are going to use is: The way…
D3 – Creating Charts
d3 is great javascript library that helps you generate SVG based graphs and charts. Over a few months I’m tasked with creating a number of different graphs and charts with an eye specifically on usability ad accessibility. The charts I am building are not particularly complex, so they make for perfect ‘how to’ articles. Before…
Bind – the zone files
This post deals exclusively with the zone files. I have written another post that deals with the installation of a bind server. For all practical purposes Zone files are separate files that are included from the main configuration file (typically named.conf ). These zine files follow a specific syntax and define all the specific domain…
Bind – Setup and Configuration of a Authoritative DNS Server
Let me start by saying that the last time I have configured and managed a DNS server was sometime around 2008. In most circumstances you don’t need one. Virtually all domain name registrars offer to host your DNS for free and they usually do a reasonably good job at it. Sometimes you have to gain…
GitLab on a FreeBSD Jail
GitLab is a great open source git repository and much, much, more. The thing i like the most about it is that I can deploy it myself and create my own place to store code, track needed changes, collaborate with others. There is a port and a great tutorial, provided by Matthias Fechner on how…
Welcome to my notes taking repository
Over the years I often found myself looking to solve a problem similar (or even identical) to one I had solved in the past. Fortunately most of the time I took notes. Unfortunately sometimes I didn’t or I did in a way that was less useful later on. This collection of problems, solutions and how…
Apache and Letsencrypt certificates
For quite some time now i have been using letsencrypt certificates for virtually any certificate need. Given that I manage several separate servers, some of which hosts 50+ sites, managing the certificates needs to be streamlined. One first thing that i streamlined was the use of a single apache config location that allows me to…
