In this video, we'll be exploring the amazing notification tool called NTFY (or notify). With NTFY, you can get notifications for almost anything you want, from long-running commands to battery levels. It's free, open-source, and can be self-hosted, making it a powerful tool for sysadmins and power users alike.
We'll start by showing you how to install NTFY on Linode, one of our favorite cloud providers, or on-prem using Docker, a Raspberry Pi, or a Cloudflare tunnel. We'll also show you how to set up the free NTFY app for Android or iPhone to receive notifications.
Once you've got NTFY up and running, we'll show you some fun use cases, including how to get notified when a long-running command finishes, when your website goes down, or when your battery is low. We'll also show you how to set up a cron job for a daily reminder or a birthday reminder.
If you're a sysadmin or power user looking for a notification tool that can do almost anything, then NTFY is the tool for you. So, join us and learn how to get notified of everything with NTFY!

DNS can be hacked….use SecureDNS from Twingate to protect yourself and your people: https://ntck.co/twingate_zerotrust
🔍 Your Web Browser is Dumb….without DNS🔍
Did you know your web browser is clueless when it comes to finding websites? When you type in a URL like academy.networkchuck.com, your browser has no idea where to go. That's where DNS, the Domain Name System, steps in to save the day! 🌐
In this video, we dive deep into the magic behind DNS. We'll break down how your browser queries DNS servers to turn website names into IP addresses, making the internet work seamlessly. From how DNS can be hacked to how you can secure your own DNS with tools like SecureDNS from TwinGate, we've got it all covered. 💻
🔐 DNS Security Tips: Learn how to use DNS over HTTPS (DOH), DNS over TLS (DOT), and other methods to keep your browsing secure from hackers and prying eyes. Protect your privacy and keep your internet safe.
🛠 Tools Mentioned:
TwinGate for SecureDNS
Raspberry Pi for DIY DNS servers
AdGuard and PiHole for ad-blocking and DNS control
Grab your coffee ☕, and let’s dive into how the internet really works!

In my last video, I built 24 websites in 24 hours. 🚀 But with such a rapid development sprint, I knew security might have taken a backseat. So in this video, I decided to don my hacker hat and attempt to penetrate my own sites using tools like Nikto, OWASP Zap, Burp Suite, and Snyk. Spoiler alert: I didn't find much. 😅
Realizing my limitations, I called in reinforcements—my friend and professional ethical hacker Tyler Ramsbey. Tyler took the wheel and performed a thorough penetration test on my websites, uncovering vulnerabilities I had completely overlooked. From exposed API keys to cross-site scripting (XSS) and even accessing hidden admin panels, Tyler shows us how a real hacker would exploit these weaknesses. 😱
Along the way, we discuss how tools like LLMs (Large Language Models) can be both a blessing and a curse in cybersecurity, aiding both defenders and attackers. 🛡⚔

Ditching the Raspberry Pi was a big move for me, especially with a month-long trip to Japan on the horizon and a tech-dependent family of eight in tow. In this video, I dive into the why and how of upgrading our travel tech setup. It's all about ensuring we've got a rock-solid, reliable travel router and NAS to keep everyone connected, entertained, and maybe a bit too online during our adventures. Follow along as I break down the journey from decision to real-world execution, showcasing the trials, errors, and eventual triumphs of finding the perfect travel companion in the tech world.
The leap from the familiar comfort of Raspberry Pi to a new solution was driven by the need for something more robust and capable of handling the demands of multiple devices streaming and accessing data on the go. This isn't just a tech swap; it's a mission to enhance our travel experience significantly. You'll get an inside look at the setup process, how it stands up to the ultimate field test (aka my kids), and whether it can really cut the mustard as the heart of our digital nomad setup. So, if you're into tech, travel, or just love a good family tech drama, this is one you won't want to miss.

In this video, I install a high-precision time server in my studio using the OpenTimeCard Mini from TimeBeat. Instead of relying on external Network Time Protocol (NTP) servers, I’m hosting my own time server to achieve nanosecond-level accuracy using Precision Time Protocol (PTP).
The OpenTimeCard Mini combines a GPS module that receives signals from satellites equipped with atomic clocks and a Raspberry Pi Compute Module 4 (CM4) acting as the server. This setup allows me to synchronize all the clocks on my network with unprecedented precision.
Additional Information:
If you’re intrigued by the fascinating world of time synchronization and want to delve deeper, here are some interesting insights and resources:
• The Precision of Quartz Clocks: Modern quartz crystal oscillators are remarkably accurate, typically drifting about 15 seconds per month. While factors like temperature and aging can affect them, advancements have significantly minimized these deviations.
• The Birth of Atomic Clocks: The first practical atomic clock was developed in 1955 by Louis Essen at the National Physical Laboratory in the UK. By 1967, the second was redefined based on the vibrations of cesium atoms, marking a significant leap in timekeeping accuracy.
• GPS Satellites and Timekeeping: The Global Positioning System (GPS) began with the launch of its first satellite in 1978. These satellites carry atomic clocks that provide precise time signals, revolutionizing navigation and global time synchronization.
• Understanding NTP Synchronization: The Network Time Protocol (NTP) dynamically adjusts its synchronization intervals, typically ranging from 64 to 1,024 seconds, to maintain accurate time across devices connected to the internet.
• Time Zones and Global Standardization: The concept of standardized time zones was proposed by Sir Sandford Fleming in 1879. The 1884 International Meridian Conference endorsed these time zones, paving the way for the global timekeeping system we use today.
• Hardware Timestamping in Networking: Hardware timestamping captures the exact moment a network packet is sent or received, allowing for nanosecond-level precision. This is essential for applications requiring extremely accurate time synchronization, like PTP.
• Raspberry Pi and Hardware Timestamping: While the Raspberry Pi Compute Module 4 (CM4) allows for hardware timestamping through additional network interfaces, the standard Raspberry Pi 4 does not support this feature on its built-in Ethernet port. The new Raspberry Pi 5 introduces hardware timestamping support directly on its Ethernet interface.
• Why Nanosecond Accuracy Matters: Industries such as financial trading, where transactions happen in fractions of a second, rely heavily on precise time synchronization. Broadcasting and aerospace also require this level of accuracy to ensure seamless operations.

Hey, Jason, thanks for reaching out!! Feel free to ask questions here....I love to answer them and I'm sure there are other guys who can benefit from it!!
I've fallen into the "Google Trap" when trying to find the "best" path for IT. I have spent WAAAY too much time trying to decide what I would like. My advice, just pick one thing and pursue it for a bit to see if you like it.
So, to answer your question, YES, definitely go for the CCNA RS. Complete it, get your cert. If you like it, GREAT! If you don't, well, it will only help you to have a CCNA.
It's a great path to go down regardless. But I agree, you definitely want to position yourself to be ready for the BOOM.
