Case Study: The Offline/Online Laptop

  alt: Three panels of a dog with a toy. Panel 1: 'Pls release IP address'. Panel 2: 'No release', Panel 3: 'Only hold onto expired IP' It's not practical for home internet services to let end users distribute their own IP addresses to their devices. The option is there, but it's far easier to let people use DHCP - You get a pool of addresses for your devices, and the router does the work in distributing them initially. That way, your devices can talk to each other and reach the internet! But what happens when one Windows 10 device is unused for months?   

Two Factor Authentication and AWS Cognito Identity Pools

There's always a video to watch. Things to learn, labs to try - and a thought hit - What service does AWS provide that allows users to log in with Two Factor Authentication (2FA)? A refresher; 2FA is a combination of what you know, who you are, what you have - and in the future, probably what you ate for breakfast - to log into sensitive systems.  As of 2021, Google made 2FA mandatory for logging in to your Google accounts For the DoD folks out there, that keycard you use to log into a computer is a form of 2FA.  A fingerprint scanner, or an authentication app on your phone also count. Back to the question - Does AWS have options for 2FA if you use their Directory options?

Animal Crossing: New Horizons 2.0 Update

The long-stagnant game has finally returned - And this time, it's actually finished.  Let's look at a little at what's arrived! Photog Fabulous The new camera features and filters are so fun. I love the eye-level view and being able to turn the camera on its axis. Which axis? You tell me. Fun fact; As I don't have Nintendo Online right now*, I sent these images to my smartphone via QR codes and a closed, ad-hoc network. Much easier than sending 4 at a time to my private Twitter and saving them. * ( Hint: Buy the Happy Home Paradise DLC before you buy the Nintendo Online Premium service; Then you have a copy to play with after your membership expires, as opposed to it being a 'feature' of the membership you can lose ) There are also neat new filters in the in-game camera: The first (surveillance) and third (retro) are definitely new.   Coffee Break Brewster is finally back! One of my favorite pastimes in New Leaf was running to the beach where I had placed The

SD-WAN Cisco Sandbox

  Want to get started using network automation, but don't have a suitable home lab? Cisco, as always, has you covered. The sandbox has configurations with special programming languages (For lack of a more clarifying term) like Ansible, YAML, or JSON, and probably Python. It's reminiscent of Cisco Live's Capture the Flag games, which I've participated in before. The site within the sandbox does not have full connectivity; Is redundancy set up? Are two routers connected to each other and one not? There's more info if you scroll to the right - "Device groups", "up since", "connected vManage", which is an SD-WAN controller that ensures visibility and control from end-to-end.   You'll notice TCP Optimization isn't reachable. This chart is the activity over 24 hours. If I sort by a smaller amount of time - say 1 or 3 - there is no data to show. Here's a reachable device. and here are the active interfaces [vedge01

Bing Webmaster Tools

    The very large "10 books in 1" tome, "Building Websites (all in one) for Dummies", something I often peruse late at night. The ways of the Old Web give me comfort. But something caught my eye. "Submit a sitemap to Google and Bing. Yahoo uses the same search options as Bing, so no need for that." Now, this book is not new (There's a section on how you need to put in some XSS code to be able to take PayPal payments on your Webpress site - Is that still a thing?), so I thought the idea of sitemaps was long gone. But. No. Sitemaps are still in use today! What is a Sitemap? It's an XML file optimized for search engines to find your website, listing every page on your website. "Spiders" crawl pages to index for search engines. Why Bing? I use Bing for my regular searching on the web. I also submitted my sitemap to Google, as my blog is hosted on their platform and my domain is purchased through them. (I'm not sure it worked. You'd t

Get in CloudFormation; A Timeline learning IaC for AWS

 A big shoutout to Pluralsight for their free weekend, and James Millar for a great introductory course . For the longest time, I couldn't see how people found this easy, but this helped. (Why did we make up so many programming languages that only work based upon the correct formatting of spaces and tabs? Readability is important, but when you're just beginning, how I learn, I'm interested in 'it works' first and 'it's pretty' second). Anyway, let's see what I learned from CloudFormation. TLDR? Check out the code on GitHub . You can use a nifty GUI getup to drag and drop elements to create a JSON file;     It's not as easy at it seems, as I had to ask myself important questions:   What's the difference between a host and an instance? Minutia ; One's more expensive per hour.   Why does this throw an error? Because YAML is picky about spacing. This required me to make Mac Virtual Machines; A first. It seems to only be available in the East

Case Study: The Disappearing Data of T-Mobile

NOTE : The problem has repeated itself. So this doubles as an off the cuff case study in level 1 troubleshooting, looking at data, comparing information at different locations.  Also - I wrote it, and I'm not wasting my time by not publishing it.  I have the Samsung Galaxy A12, and the service through T-Mobile is pretty good. While the infrastructure around our nation is fair at best, it's showing it's age and weakness in storms - and that may apply to private towers owned by T-Mobile as well.  I turn on data, and either: It works The symbol in the upper right does not show up and it's not working. The symbol shows up and the data still doesn't work.     Here's a demo; Other videos are available upon request. Now, there is a setting where I can change the mobile band (2G/3G, 3G/4G) my phone uses, something I was unaware of until a cool Twitter user let me know. This alleviates the problem sometimes, but if I go hours without using data, the problem returns.  Cou
