Please note, this article doesn’t address recording or streaming using an Elgato card on Linux. Rather, this article discusses capturing output from Linux to Windows. With that setup, I ran into an issue where I received a ‘No Signal’ when attempting to record from Linux to Windows using an Elgato…

In a previous article, we looked at how to safely transmit a backup from the client to the server. In that article, the data was transmitted from the client to the server over an encrypted channel. However, the server would store that data unencrypted. That left anyone with access to…

These extensions adds additional information to a certificate. In a later article, we need these extensions to be included. So, I’ll expand on previous OpenSSL articles and show how we can add these certificate extensions using OpenSSL. Background Extensions add additional information to a certificate. For example, it can specify…

For the past couple of weeks, I’ve been considering putting together a video course that will provide an introduction to Bacula. If I get enough interest, I will put together this course and this is where I need your help. Course overview First, a little background. Having written several articles…

In this article, I wanted to go through a Python script I created recently, that generates keys and self-signed certificates using OpenSSL. The reason why I wrote the script was to make the generation of multiple keys, certificate signing requests and certificates for test environments easier. I discussed how to…

In this final article on how to monitor Bacula from Zabbix, we’ll look at how to configure a template with items and triggers. We’ll create a new template that will contain the items we’ll monitor. Then we’ll add the items, such as files written, rate, job successfully completed etc. Finally,…

In the second part of the three part series on how to monitor Bacula from Zabbix using Postfix and Python, we’ll look at how the Python script works. This part is not required reading. However, if you are interested in how the script is structured and what it does, you’ll…

In this three part series of articles, we’ll go through how to configure Zabbix to monitor Bacula jobs with the help of Postfix and a Python script. First part of this article will look at how we configue Postfix to receive data from Bacula. So, in the previous article, we…

Continuing on in our Bacula series, lets look at how to configure email notifications from Bacula using Postfix. In this example, we use GMail as the email provider, however the settings here should be applicable for most providers. First we need to generate an app based password if you have…

In this article, I wanted to briefly talk about how to generate keys and certificates in OpenSSL using a configuration file. In how to configure encrypted connections in Bacula, I wrote about how to do this via the command line. After the article, I was doing some research on OpenSSL…

In this article, I wanted to mentioned a couple of configuration issues that I ran into when implementing TLS in Bacula. In my previous article, I showed how to generate keys and certificates and editing Bacula configuration to implement TLS. However, during the configuration process, I ran into several issues…

As part of the Bacula series, this article discusses how to configure encrypted connections using TLS in Bacula. We’ll quickly go through how to setup a Certificate Authority (CA) as Bacula requires there to be a CA to sign the certificates for the client and the server. Then we’ll go…

In this article, we are going to explore who to use full, differential and incremental backup types to improve on our current Bacula setup. First, we’ll look at the differences between a Full, Differential and Incremental backup; then we’ll add a those to the Bacula server; finally perform some backups…

In this article, we are going to look at how we can restore a backup of the Linux root directory using Bacula, back onto a Linux machine with a Ubuntu LiveCD. It’s assumed that you have a backup of a Linux machine’s root directory made by Bacula. How to achieve…

I’ve been running Pi-Hole as my DNS resolver and Ad Blocker for a couple of months now, and I’ve always had an issue with Pi-Hole not resolving DNS requests whenever I reboot the Ubuntu Virtual Machine. In the past, I’ve managed to fix the issue but unfortunately not spent time…

I recently got stuck with some compiler errors after I added Mocha to my TypeScript project. Having decided to try Mocha and Chai for my NodeJS TypeScript project, I added the testing framework using; npm install chai mocha ts-node @types/chai @types/mocha –save-dev I wrote my test suite and compiled and…

In this article, we’ll see how we can configure automatic backups by adding schedules to our Bacula configuration files. Having the confidence that our machines are backed up on a regular basis, ensures that we can restore our files in case of a disaster. Now, a disaster could be complete…

In this article, we will go through how to monitor UniFi Controller values using Zabbix Server and custom templates. Zabbix is a network monitoring software, where we can have multiple servers reporting details about their status, such as network connectivity, disk space, available memory etc. The UniFi Controller is software…

In the previous article, we looked at how to install, configure, backup and restore files from a Linux host to a Linux Server. In this article we are going to expand on the previous article and be adding a Windows host to our Bacula setup. I’m going to start from…

This article gives an introduction to Bacula. We’ll cover how to install and configure Bacula, an open source, distributed and highly customizable backup solution. We start with installing and the configuring the server, before we install and configure the client. Then we’ll cover how to perform a very basic backup…

I recently had some downtime and decided that I was going to give my website a quick once over. I ran the site through PageSpeed Insights and it came back with a score of… 15. Which is, to be honest, absolutely terrible. Digging through the list of errors, and there…

The other day, my current 24 port managed switch died, so I finally purchased a 24 port PoE capable switch. After having configured the new switch, I brought out two Netgear PoE switches and decided to put them into production. Upon booting them up, I needed to upgrade the firmware…
