LVM: Volume Management
Right now, I’m using a Linux (CentOS) VM running on VirtualBox and my raspberry pi 3 B running next to it. The latter has a Kali distro running on it. It’s been interesting being able to play with different commands while studying from my Linux+ exam prep book! My goal is to use LVM logical…

Copying text to diff files within Vim
I have been working with my raspberry pi as I get practice with networking skills, and with these really long key spaces, I had been having to peer closely at the key strings and type them into the appropriate file. Sometimes more than once a day, as I had been experiencing Rpi technical difficulties (read,…

From MBR to GPT partition, gdisk
Yesterday was my first foray into storage management, and I approached the various tools and processes with seeking to better understand the why’s and how it fits in with my current understanding of working with Linux. This morning, I decided to unmount my USB memory stick and try a new process and tool set- whereas…

Filesystem, mounting, partitions, oh my!
A lot of information got crammed into my brain tonight as I tried to understand the broad strokes of filesystems (for Linux), the different options available, then looking at some of the tools that are available for modifying filesystems. I tried parted and gdisk, but wound up feeling more comfortable with fdisk- for a starting…

Maximizing Cloud Computing

The nodes are closer to the edge devices, minimizing latency and allowing for greater capacity for data storage. One can see security vulnerabilities, though- possible DoS, hijacking, bottlenecks, and so…

Connecting VM Centos 7 to internet
I have a Centos 7 virtual machine on my virtualbox hypervisor, which has been great for practicing vim and such. However, when trying to get onto the internet, I wasn’t successful- and poking around the configuration settings of the software platform didn’t seem to work (without doing a deep dive, anyways). I followed this video,…

AWS: Configuration for CLI
There are a number of hoops to jump through steps to take in order to have access to a local CLI on your local production environment (read, my mac at home, with a coffee mug perched nearby): take a look here. First, to create IAM access and credentials. We need to get authorization, basically, through…
