Linux, Hardware, Software and Chaos. What more is there?
It’s a tale as old as time. Great and stable Internet connectivity that’s hamstrung by a really sub-par CPE gateway device. AT&T fiber is no exception, if at anything, it’s the perfect example of this situation. The reliability and consistency of fiber, but their CPE gateway is known for causing all kinds of networking issues. In this article, I’ll be talking about what I had to go through to replace it with a Cisco ASR-1001.

Over the weekend, I was digging through the expansive parts bin known as the computer room and I had my old Unifi Video NVR jump off the shelf at me. While the Unifi Video product has long since been discontinued, giving way to the Unifi Protect line of NVRs and products, the hardware itself still has a bit of life left to it. In this article, I’ll go over the hardware of the derelict product and see what we can do with it going forward.

In this article, I’ll be discussing how to use the Nagios NRPE (Nagios Remote Program Executor) service to monitor the remote secondary OPNSense firewall in a high availability configuration to overcome a VPN routing limitation where the secondary instance is not reachable. The root cause is due to the way the VPN routing is performed in OPNSense where the incoming traffic flow won’t communicate due to a routing conflict. While this issue isn’t an OPNSense specific issue (it affects pfSense and other firewalls that use HA/CARP with VPN).

Just like with most things, IT equipment has to evolve over time and wireless connectivity is one of those things. The company I work for decided to replace their aging Ruckus controllers and access points with Meraki access points (The decision was way above my paygrade) so that left a treasure trove of hardware behind that was destined for the waste bin. In this article, I’ll talk about the HA pair of the SmartZone100 controllers from Ruckus, their hardware capabilities, and what I plan on doing with my pair.

The Emergency Alert System (EAS) is a US Nationwide alerting platform that uses a combination of terrestrial radio and television broadcasters to get an urgent message out to as many people as possible. In this article, we’ll be setting up the TFT EAS-911 ENDEC so we can receive these messages without being dependent on cellular service or Internet access.

While the future of pfSenseCE and pfSense+ are still very much in the air, it at least brought us the option to use ZFS mirroring for hardware redundancy. Good news is that it works well, I didn’t even know the drive had failed for several months until I had to powercycle the router and heard the click of death. Bad news, it’s not really adequately documented anywhere how to do this and it’s not for the faint of heart!

In Part 1, I discussed the research, physical installation, a bit of maintenance, and the overall basic operation of the Generac 22kW Guardian whole home generator. In this post, we’ll go over the monitoring of the generator and quickly outline the vendor’s supplied option as well as the Open Source option I decided on, and even up contributing to! Yes, even though I’m not a developer, I managed to contribute to an Open Source project and helped the developer out!

Being a homeowner isn’t for the faint of heart, there’s always a chance for things to go wrong, especially considering that we’re in Texas and well… *gestures at the Valentine’s day week of February 2021*. So with that being said, as soon as the ink was dry on our house contract and we had closed, I was already in process of soliciting for a standby whole home generator. This three part article will cover everything from the decision making process of the generator and its installation (this article), how I monitor the generator using GenMon, an opensource application suite on Github (Part II), and lastly, how I implemented Grafana, Prometheus, and SNMP Exporter (Part III) to get the level of monitoring I am comfortable with.

So, if you’re a Texan, you already know who ERCOT is and you already know what’s going to happen in the next few days. If you’re not Texan, or you haven’t been eyeing the weather, it’s going to freeze. If you’re not sure what the connection to freezing weather and ERCOT, I’d recommend reading up on it here: Wikipedia This quick hack article isn’t about them per se, but something that might be helpful to keep an eye on the grid in the upcoming winter storm.

This article is going to be different than the others that I post simply because there’s no delicate way to approach the subject of death. Unfortunately death is inevitable and as with many things, there’s tasks and talks you can do now (even if they’re uncomfortable) to ensure that your online presence will live on when you eventually pass.
