Over the weekend, China launched a satellite into low-earth orbit, the first step of a plan to provide global satellite internet to people who still don’t have reliable access. Nearly 3.8 billion people are unconnected to the internet, and women and rural poor are particularly affected.
The satellite, called Hongyun-1, took off at China’s national launching site Jiuquan Satellite Launch Center on Saturday (Dec. 22). Hongyun-1, or “rainbow cloud,” is the first of 156 satellites of the same name developed by state-owned spacecraft maker China Aerospace Science and Industry Corporation (CASIC). A Long March 11 rocket, made by another state-owned firm, China Aerospace Science and Technology Corporation, carried the Hongyun-1.

China got on the bandwagon to provide global satellite internet

Pi-Hole is a network wide DNS sinkhole that can be setup on multiple software/hardware configurations. Originally, I was going down the path of setting up Pi-Hole on a Raspberry Pi 3, but decided to explore the Azure VM path based on some posts from others.

Below are the high level steps I followed to setup Pi-Hole on my home network.

1.Create a VM in Azure and keep track of the public IP. (I picked the Ubuntu 18.04 LTS version with 1 CPU and 1 GB of RAM.)

2. Create an inbound firewall rule to enable SSH traffic (i.e. TCP Port 22) from your home network

Home > Virtual machines > Connect to virtual machine > Networking

3. SSH to the VM and update the package database

sudo apt-get update

4. Install Pi-hole

curl -L https://install.pi-hole.net | bash

5. Configure Pi-hole for your environment. Some suggested configuration options are below[2]

6. Create an inbound firewall rule to enable Web traffic (i.e. TCP Port 80, 443) from your home network

8. Confirm you can access the Admin page of Pi-Hole by going to <VM IP>

9. Create an inbound firewall rule to enable DNS traffic (i.e. TCP/UDP Port 53)

10. Update your home router’s DNS to point to the public IP of your VM by following instructions at How do I configure my devices to use Pi-hole as their DNS server?

11. Test that Pi-Hole is properly configured by visiting the Pi-Hole Ad Pages Test Page.

[1] Post Implementation Notes:

  • Under the VM, check Operations > Auto-shutdown to confirm the settings match the shutdown behavior of the VM you want
  • Under the VM, check Operations > Update Management to confirm the settings match the OS automatic update behavior you want

The following blogs posts were extremely helpful with the steps required to setup Pi-Hole in Azure and modifying some Pi-Hole settings to work for most home needs.

After some recent infrastructure changes, I noticed that certain group policies were not being applied due to network connectivity lag as a result of how our systems were setup. To resolve this, I stumbled on a post that describes a Group Policy setting that can force the computer to wait for full network connectivity before logon.

To enable this setting:

  1. Open the Local Group Policy Editor
  2. Expand Computer Configuration
  3. Expand Administrative Templates
  4. Expand System
  5. Expand Logon
  6. Enable the Always wait for the network at computer startup and logon setting
  7. Restart your computer

Ed Sutton on the dangers of big data and how everything we do, online or offline, leaves a digital footprint behind. He describes how every purchase with a card, every search, every movement with a smart device and every social media interaction (Likes, Retweets etc.) get stored. When used in aggregate, this data reflect a social and identity fingerprint that uniquely identifies you and furthermore can predict your behaviors and responses.

The Big Five: Openness (how open are you to new experiences?), Conscientiousness (how much of a perfectionist are you?), Extroversion (how sociable are you?), Agreeableness (how considerate and cooperative are you?), and Neuroticism (how sensitive/vulnerable are you?). With these five dimensions (O.C.E.A.N.), you can determine fairy precisely what kind of person you are dealing with—their needs and fears as well as how they are likely to behave.
