Raspberry Pi Zero
Today I worked on configuring my Raspberry Pi Zero, which has been tucked away in the recesses of my workarea, along with my 5″ Elecrow monitor. Here’s what I did to make the magic happen: First, I downloaded the simple Raspbian OS 32-bit and flashed it to a 16gb SD card. Following this tutorial, I…

Exploring Wireshark
I have to admit that I find the networking courses through Cisco’s Academy to be quite challenging. I’m learning a ton, but my to-do list for the day always comes screeching to an abrupt halt when I tackle my daily Packet Tracker practice and coursework, because it all just takes so long. But, I’m definitely…

ARP Tables
Continuing to experiment with All-Things-Networky using Cisco’s Packet Tracer. Here’s the network: Here’s the addressing table. Two routers, two laptops attached to the wireless access point, and three PC clients- IPv4 addresses, MAC addresses are as follows: First, I used the CLI/terminal on client 172.16.31.2 to ping the client at 172.16.31.3, first clearing the ARP…

Network exercise
Given the following network: I found the IPv4 address and MAC addrress of PC0 by opening up the (virtual) CLI and running ipconfig /all IPv4 address: 10.1.1.1 MAC address: 0060.473E.9176 Next, I pinged another host @ 10.1.1.5:

So far, I’ve completed ‘Pentesting Fundamentals’, ‘Junior Security Analyst Intro’ and am now working on the three-part Linux series. I’ve completed the first two “rooms” (which is what THM calls a module for learning a certain focus, complete with a virtual machine for running…

PKM: Adventures with Obsidian
I stumbled across an interesting thread around keeping notes of things learned, such as configuration, machine installs, good sites, etc, and Obsidian was mentioned. I’ve been using Evernote on an occasional basis, but after reading the posts, I became interested in the concept of an overall Personal Knowledge Management system. I decided to explore the…

CentOS VM
Up until the last day or two, I had had these disparate threads of understanding around programming, APIs, servers, networks, Linux, and so on. What I mean is, I had undertaken many of these aspects within silod processes of learning- I learned how to do front-end programming in Bootcamp. Later, I learned to work with…

Adding Python Modules
I’ve been reading through ‘Linux Basics For Hackers’ and have found it a good introductory text for understanding the Linux ecosystem. Here are some of the core things around Python modules and installation: Third part modules can be found at PyPi (http://www.pypi.org): You can use pip (install : > apt-get install python3-pip) Downloaded packages are…

Linux & MySQL/MariaDB
It’s interesting because I have always been drawn to understanding the big picture of things, and back when I first shifted to IT, I was intrigued with working with databases (and left me feeling dissatisfied with solely front-end stuff). I’m circling back to that, now, as I continue my Linux journey, and I find myself…
