  • exploring nmap

    While learning linux and networking, I am learning to tie in different streams of information through using tools like nmap. For example, I am becoming more familiar with creating a new terminal on my kali box using Ctl + Alt + F<key>, setting root permissions, then having nmap run an aggressive scan on nmap.org’s box,…

  • Mounted Drives and Persistence

    I ended my previous post right before I edited the fstab -why, you might ask? Well, the first time that I edited this file, I used spaces to delimit the various values, when actually a tab should have been used – except for the final two values, around dumping ability and priority, which uses a…

  • Config RAID and Logical Volumes

    I’ve written a few posts as I learned how to create a logical drive, and touched upon RAID systems too- in this post, I’ll combine the two together. There are three main steps, in part I, with creating a logical drive: 1. Create hard drives that will become LVMs 2. create volume group(s) and 3.…

  • 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…

  • Hyper-V Virtual Machine Practice

    I’ve been spinning up VMs using VirtualBox (by Oracle), including Centos 7, Kali Linux, Ubuntu- and for this exercise I am jumping into the Windows world to spin up a VM there. Above, you can see that I used the VM Wizard to provide the attributes that I want, setting memory size, networking (external), hard…

  • 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:
