AAA: Authentication, Authorization, and Accounting
A good way to become accustomed to using the Terminal is to just use it. Ideally for as much of your normal tool-chain as you can. In this article I will document how to use the Linux Terminal to download an Ubuntu OS image from Canonical and then check it’s SHA256 checksum to ensure it is authentic. One thing that we all should do is verify that the images we are pulling from Canonical, Red Hat, Suse, Fedora, etc., are legitimately the images we think they are and not the image a hacker wants us to use? Well, looking for the lock symbol next to the URL at the top…
Gaming on Linux!
Yeah, that’s right. Linux. Gaming. The operating system that rules the interwebs, powers all major supercomputers, light bulbs, and hobby Raspberry Pis, actually plays games! And of course it does it VERY well! So, to be clear most games written currently are written with Windows10 as their main audience. But many are written for Sony’s Playstation, which runs a variant of Linux. Also some are written to target Google Stadia, the online games channel for Google and these are also running Linux, and a very mainstream version of Linux. If you wanted to have all the security and stability features of running Linux. But you want to get your gaming…
Network Model Abstractions
I’m working through the Cloud Foundations certification curriculum currently. And in section 6.1.2 “Identifying OSI model layers” there were some charts that dealt with the OSI model, but I noticed things were different. I did the CCENT curriculum last term where the 7 OSI layers are reduced down to 4 because the TCP/IP stack only uses 4 logical layers, and wanted to see how the ‘new’ changes all work compared to the older model I learned originally. All of us geeks have our own way of understanding the 7 OSI layers and how they map onto real world troubleshooting. And how the TCP/IP model simplifies it for the specific use-case…
For Cloud or Desktop
I am on corona-virus ‘Emergency Leave’ from my employer at the moment. I have pretty bad HBP, so am considered hi-risk and was given 4 weeks of leave. I am lucky enough to be paid for this time off, so I have no issues with bills due to this, and therefore have lots of time on my hands to do pretty much as I please…at home. I have been enrolled in college to get my bachelor’s degree for almost 4 years now, WGU for Network Operations & Security. My current class nets me the CompTia Cloud+ cert at the end of it along with 4 credits. In pursuit of that…
It is 1:10am on April 11, 2020. I am sitting at home courtesy of my employer, at full pay for either 2 or 4 weeks. I’m not sure how that is determined, but I’m still home for another week regardless. I am grateful. Two weeks ago, reported new unemployment claims came in around 3.5 million. This is with not all states reporting, and so many claims came in so quickly that the number we have may be a bit lower than actual unemployment claims. Last week there was over 6 mil more and this week another 6 mil. That’s like 16 million people out of work in under a month…

This is the first post for the all-new Olympic Softworks website. Over the years I have had several ideas that always wound up being somewhat complicated to launch. So I’ve decided to go back to basics. Since I am working full-time as well as working on my B.A. in Network Technology & Security, Olympic Softworks the organization is on hiatus as a physical presence in the community. But I am still doing things that are creating possible relevant content as school projects or pet personal projects done in what little spare time I have between work and school. So as part of my efforts, I will try to package them…
