  • Expanding VM storage

    I want to experiment with configuring LVM on partitions, but the ones presented on my Ubuntu 22.04 VM are not available. I followed this tutorial for creating an additional partition, once that I would be able to practice on. Select the VM in question, then select Settings and Storage. Next, select the Controller, as indicated…

  • 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…

  • SSH From Mac to Ubuntu VM

    I had an Ubuntu instance running on VirtualBox- now, how to SSH that to my Mac? Is it possible to bring that virtual-to-“real world” machine running on the same network? Very curious to find out.. First, I downloaded openssh-server: Next, enable and start the SSH service:

  • Setting Calendar Info for Centos 7 VM

    I’ve been learning about cron jobs but when it was time to get my hands dirty, I discovered that the time for my VM was way off! What to do? I found this site, which helped quite a bit. Here’s what I did: And with that, the system was updated.

  • 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,…

  • Networks: Implementation & Troubleshooting

    I’m currently taking a Networking class to help meet my goal of successfully passing the CompTIA Network+ exam. The class offers virtual machine labs where I can put into practice the theoretical learning- really helpful! So, for example, Networking Addressing and Services in the subject matter, which included a number of important topics: IP Addressing,…

  • RaspberryPi and Hardware Control

    This post is going to be somewhat rambling without a clear destination, as this is my initial foray into configuring the Rpi to interact with sensors and such, and thus will be filled with my pokings and proddings. Here we go! First, I have been using the book ‘Make: Linux for Makers’ by Aaron Newcomb,…
