  • 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,…

  • Access Control Lists

    For files and directories, permissions can be set in terms of the user, group and other. Read has a value of 4, Write has a value of 2, and Execute has a value of 1. So, if one wants to change the permission of a file, one can add those numbers to the permission level…

  • 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:

  • Learning Linux on TryHackMe

    TryHackMe is a great resource for hands-on practice in different areas. 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…

  • 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 & PostgreSQL w/ Metasploit

    Postgres is another open-source DB that is good to know, as it is powerful for large, internet-facing applications and scales well. In case it needs to be installed on the Linux distribution: Now let’s start that bad boy: and then start Metasploit:
