Enterprise Linux Security Episode 59 – AlmaLinux OS
AlmaLinux OS was created around the time of “that big CentOS” announcement, and has been a worthy solution for enterprises that wish to continue with Enterprise Linux, but without the fear of the distribution being changed into something else entirely. As a drop-in replacement for Red Hat, AlmaLinux OS continues to tackle new ground and builds a strong community. In this video, Jay and Joao are joined by Atalay Kelestemur who works on the project to discuss this distribution – and there may even be some surprises in store.

The Homelab Show Episode 90 – Netdata

Netdata is an awesome monitoring solution that’s easy to set up, and has a ton of features. Jay had a chance to test it out recently, and Tom and Jay share their thoughts. Also, we’ll talk about some new software releases, why static leases are greater than static IP’s (well, Jay seems to think so anyway). In addition, some viewer questions will be answered. Check it out!

The Homelab Show Episode 86 – Cloudflare Tunnels

Should you expose your Homelab services to the public Internet? Normally, that will also expose your services to threat actors as well. However, sometimes public access is required for the use-case of a server. Historically, this has been a complicated and debated topic – consisting of technologies such as VPN, Dynamic DNS, and others. Now, Cloudflare has a solution – Cloudflare Tunnels. In this video, Jay and Tom discuss this feature of Cloudflare and will help you determine if it’s a good fit for your homelab.

Enterprise Linux Security Episode 53 – Digital Twins
By using clever infrastructure engineering strategies to increase reliability, you can minimize disruption and downtime for your organization. Another technique to consider is the concept of Digital Twin – having a full system clone/mirror you can use to test enhancements, perform a root-cause analysis, or more. In this episode, Jay and Joao discuss Digital Twins and how the concept can potentially help your organization.

Enterprise Linux Security Episode 51 – Samba in the Kernel, What Could Possibly Go Wrong?!
Adding unnecessary components to the Kernel is generally a bad idea, as it increases its threat surface. In this episode, Jay and Joao discuss a recent story that’s a perfect example of why it’s important to keep this under control. A vulnerability was recently discovered in the Linux kernel that scored the highest possible rating, and it all started when ksmbd was added.

The Homelab Show Episode 82 – Server Monitoring
If you have one or more servers that need to always be available and ready for action, how do you keep track of uptime? How can you receive alerts to notify you when there’s an issue? In this episode, Tom and Jay discuss some of the tools they use to monitor servers and important metrics.

Enterprise Linux Security Episode 49 – The Code is Open, But Who’s Looking at It?
Open-Source is great – with code being open, everyone has access to it. That means that the code can be audited – and that makes it more secure, right? Well, possibly. In the recent talk “The Code is Open, But Who’s Looking at it?” Joao discusses the concept in detail. This talk was recorded at OSAD 2022. New episodes of Enterprise Linux Security will resume after the holidays. But for now, enjoy the talk!

The Homelab Show Episode 81: Building Lab Templates and Images

When building a new virtual or physical server, doing everything manually is a waste of time. With an image or template, you can have some of your recurring tasks already set up on the image – and then every instance you create from that template will have all of those tweaks already made. But how far should you go with this default setup? What are some of the caveats that you might run into? In this episode, Jay and Tom discuss creating server images/templates and the related shenanigans you may run into while doing so.

Enterprise Linux Security Episode 48 – New Malware, Old Vulnerabilities
While it’s certainly never a good thing to become the victim of a cyber-attack, it can be even more embarrassing if the CVE the threat actor used to get a foothold into your systems was patched a long time ago. In this episode, Jay and Joao discuss malware that’s currently taking advantage of vulnerabilities that were patched over a year ago! As important as software updates happen to be, why are so many organizations unable to keep up with them?

The Homelab Show Episode 80 – The “Automation” Mindset

As most of us homelabbers are aware by now, automation is a very good thing – repeating (and sometimes tedious) tasks can be automated, allowing us to focus on things that are better uses of our time. But Automation itself seems to have its own mindset, especially when it comes to how you go about approaching some of the challenges. In this episode, Jay and Tom discuss the Automation Mindset.

Virtual Machines and Containers are awesome, but when should you use one versus the other? In this episode, Jay and Talk about some of the deciding factors when it comes to deciding which technology to use.
