In case you missed it, the largest recorded Direct Denial of Service (DDoS) occurred. While under DDoS, a victim’s server (or servers) is under high load and cannot complete all requests that are requested by it. Basically, a DDoS victim is someone the attacker wants silenced on the internet. In order to send a DDoS of […]
I completed my first public module for puppet and submitted it to the puppet forge. It seems too simple to compile into a build and submit it to the forge; however, I made it public for these reasons: I needed experience with puppet code testing. This helped me at the most basic level. I felt […]
One of the easiest ways to deploy a virtual machine in oVirt is first to install the OS then turn it into a template. This will allow you to copy that template to deploy new instances. One mundane task after a new template is copied to a new instance is logging in, changing the IP, […]
In last week’s post we set up PWM insecurely. In this post, we are going to secure it down and install mysql to store the reset questions. This guide assumes you have this CentOS 7 server publicly accessible with ports 80 and 443 available to the entire world. First, we will need to install mysql, […]

In a previous post, I explained how to set up a captive portal on a Raspberry Pi which was running Raspbian (Debian). If you read that article, you can skip the next paragraph. A captive portal is a piece of software that prompts for user interaction before allowing the client to access the internet or […]
Let’s face it, Linux is a kernel and no matter what distribution you use, it is all the same. You have a repository of packages, you get a package manager to manage your packages, you get a desktop environment, and you get freedom to tinker down to the lowest level of the kernel to configure things […]
Do not get me wrong – I use Ubuntu and try to contribute to bugs (making and fixing). In fact, I am testing out 16.04 on my Chromebook and work computer right now (Fedora 23 is on my Home Desktop). However, I can’t find myself placing an Ubuntu server in production for one simple reason:
Chromebooks are cloud focused. Many Chromebooks come with very limited storage in hopes you would be storing everything in the cloud. While this is a great habit to practice, in all reality, how likely are you to store 2tb of data in the cloud? Not many cloud providers even offer plans for that much storage.
Having a server in the cloud scared me at first. It wasn’t the fact that being in a multi-tenant environment posed the possibility of others gaining access to my code/files – it was the cost that scared me. Not knowing if I was getting the best deal always plagued my mind. Especially since electricity, a/c, […]
A few years ago I was tasked at looking at solutions for digital, static wayfinding. While there are some cool solutions available now for free with minimum setup, none of these were available to me. We currently were locked in with a digital signage company that charged $7,000/year for generating 640×480 graphics with events that […]
A stack is a group of software that creates a foundation to build upon. The LEMP stack is a web software stack which allows for delivering web applications. It is one of the most common of the web stacks to deliver a PHP application. LEMP uses a Linux kernel, Nginx for the webserver, MySQL or […]
I particularly enjoy using a web browser to administer GUI appliances. In the case of oVirt, it does become a little painful to do the Chrome-zoom-click on my massive 4k Android phone. It appears the oVirt devs have also seen this pain point and have released an Android app to make adminstration easier on Android. […]
With the release of MySQL 5.7, I was pleasantly surprised to see the install generated a random, secure password. This prevented me from going through the normal step of running mysql_secure_installation after starting and enabling services. To find the generated password, issue one of the commands below:
I recently received a subscription to Linux Academy. Linux Academy has courses in Linux, AWS, DevOps, and OpenStack to help users achieve professional certificates such as the LFCS, LFCE, RHSCA, RHCE, and others. Since my LFCS is expiring this year (and I hope to achieve a RHCE), Linux Academy seemed like a place to help […]
