Introduction

This Gist contains a few tips and tricks that I've gathered over time to optimize my experience when working on unix based systems. Some of the things mentioned in this document, will explained in further detail below. This file will contain things in a more compact manner.

General Networking

Ping

Ping though a specific NIC:

Find the default network configuration file:

$ ls /etc/netplan/
50-cloud-init.yaml

Check the contents of the file:

Secure Arch Linux Install

Following this guide from YouTube: https://www.youtube.com/watch?v=gB1N00wj3bw

This installation procedure follows installing a secure encrypted lvm version of Arch Linux on my MacBook Pro in Parallels.

Harddisk Setup

Let us start by looking at the naming of harddrives:

Setup GPG Key

Install latest GPG version (the one MacOS ships with is out of date):

$ brew install gpg2 gnupg pinentry-mac

Create a new GPG key

Configuring a secure Linux Server (i.e. Raspberry Pi)

This guide will configure a simple secured linux server. In this example, I will configure a raspberry pi.

Prepare SD Card from Mac OS X

This section is for preparing an SD card with Raspbian from a Mac. Start by opening a terminal. Start by downloading the latest version of raspbian:

curl -O -J -L https://downloads.raspberrypi.org/raspbian_lite_latest

	#!/bin/bash

	### Set UserName
	echo "Ready to start"
	read -rp 'UserName: ' uservar
	echo "$uservar added"
	#adduser $uservar && echo -e "$userPass\n$userPass\n" \| passwd $uservar > /dev/null 2>&1 && echo " User account has been created." \|\| echo " ERR -- User acount creation failed!"
	adduser $uservar
	usermod -aG sudo $uservar
	USER=$uservar

	#!/bin/bash

	# Call this file with `bash ./project-create.sh project-name [service-name]`
	# - project-name is mandatory
	# - service-name is optional

	# This will creates 4 directories and a git `post-receive` hook.
	# The 4 directories are:
	# - $GIT: a git repo
	# - $TMP: a temporary directory for deployment
