Pi-hole DNS Blocking

Its been a while since posting anything new so here it is.

Pi-hole is a Domain Name Service (DNS) sinkhole. The Open Source project at pi-hole.net is intended to improve web browsing security and overall browsing experience.

The software can be installed in a variety of ways – I decided on the Raspberry Pi method. Now my local Raspberry Pi 3 acts as a DNS cache/resolver/sinkhole/filter on my local network.

My overall browsing speed has increased and I feel that the level of security is appropriate. Of course the browser can easily get confused on what to display if a website is blocked and most of the time a simple space is added. Works with all client OS’s, Linux, OS X, IOS, … .

 

Data Recovery

A recent client required old data to be recovered from multiple external disk drives from old computer systems. After the data was recovered, each disk was wiped clean then destroyed mechanically before sending to electronic recycling.

The picture below is from one of the disks with two holes drilled through the platters of the drive. These holes prevent any chance of any further chance of data recovery.

The Need For Better DNS Privacy

Every time a website gets accessed using a name, that name must be translated into a physical address using Domain Name Services (DNS). As with anything that is a ‘free’ service, there usually is a catch of some sort. The current catch is this information can be sold to see where people are going on the Internet. Depending on an individuals comfort with their personal privacy, you may want to change this. Using a DNS service that doesn’t record or sell their records and is fast can be hard to find.

The solution is Cloudflare. Follow the link and read about why they came to be and the importance of privacy for DNS. 

I run 1.1.1.1/1.0.0.1 on all my my personal equipment and the performance is great. I also have the peace of mind that my information isn’t being profiled or sold on to other data mining companies.

Finishing Website

Finishing Website

Working with WordPress 5.x self hosting on ord.ca to finalize version 1.x of the website. WordPress and great themes make this a very simple job … just add content.

The basics are now setup with a skeleton of information available. I hope to keep the site as up to date as possible.

On to more pressing issues like pricing examples and additional detail in services.
