Introduction In March of 2018, Let’s Encrypt (the free Certificate Authority) announced they added support for wildcard certificates through the upgraded ACMEv2 protocol. I’ve been hosting most of my services on subdirectories (e.g., loganmarchione.com/rss) but have been wanting to move them to subdomains (e.g., rss.loganmarchione.com), and thought this was the perfect chance to do just that. What are wildcard certificates? Wildcard certificates cover any subdomain of a specific domain. For example, I own loganmarchione.com. Because of this, I can create services as subdomains of that domain. For example: ...

Introduction In my last post, I talked about setting up an ODROID-HC2 as a NAS using OpenMediaVault. I have that up and running, and I’ve also written a few scripts to backup my data to a few of the SMB shares. Now, I need to get that data shipped offsite to an external location to cover my 3-2-1 backup strategy: 3 backups 2 different types of media 1 backup offsite Software My cloud storage provider of choice is B2. I’ve written about them in the past and have generally had good luck with them, so I’d like to keep using them. ...

Introduction I’ve been doing some work on my homelab that I haven’t documented here. I recently decommissioned my Raspberry Pi 3 that was running my Unifi controller, Dokuwiki, and Network UPS Tools (NUT). I replaced the RPi3 with an Intel i3 NUC with 12GB RAM and a Crucial 2.5" SSD. I chose to use Proxmox as the hypervisor on the NUC because it is open source, has a well-proven record, and has a low learning curve. At the time of this writing, I’m running five KVM virtual machines: ...

My Dyn setup is documented below. ...

Introduction While creating CAA records, I found myself needing a new DNS provider. During that process, I thought it would be a good idea to document what it take to host a website and how the internet works (in a very limited sense). To host a website on the public internet, you need three things: domain name DNS record(s) web host Typically, most domain registrars offer basic DNS support. In addition, most web hosts also offer basic DNS support. However, you can (and probably should) have these three services hosted at three separate companies (you don’t want all your eggs in one basket). ...

Introduction Certification Authority Authorization (CAA) is a new DNS record specifying which Certificate Authorities (CAs) are allowed to issue certificates for a domain. Introduced by RFC 6844, CAA protects websites by only allowing certificates to be issued by specific CAs. If an attacker were to take over a website, they would only be able to obtain a certificate from a CA specified in DNS CAA records, limiting the damage they could do. While CAA records aren’t going to completely stop certificate misuse, they are easy to implement and are part of a larger security plan. ...

Introduction Recently, I’ve been thinking more and more about backups for my small (but growing) homelab. The golden rule is to follow the 3-2-1 method for backups: 3 backups 2 different types of media 1 backup offsite Current setup Currently, I keep an encrypted external HDD at home and another at work. Every couple weeks, I perform a backup to both and rotate the drives (this covers a 2-1-1 backup). ...

Introduction With the winter weather, we’ve been having brownouts and power losses more frequently. I wanted to purchase a UPS to protect my equipment from this, but I also wanted to receive alerts when the power goes out, and possibly shutdown equipment. For this, I need an Uninterruptible Power Supply (UPS) and a computer to monitor it with. Hardware As you guessed by now, I’m going to be using my Raspberry Pi to monitor the UPS. I’m using the Raspberry Pi because it is a low power device, it is always on (hosting a webserver, Unifi controller, and a few other things), and can be run off the UPS it is monitoring. ...
