Hugo is a static site generator written in Go. It allows building fast, secure websites without the need for dynamic servers. It’s especially designed for developers, technical writers and anyone who prefers writing content in Markdown and publishing it quickly with a professional design. Perfect for maintaining my technical notes and personal documentation. It’s known for its compilation speed and for not requiring external dependencies like databases or complex template engines. Ideal for blogs, documentation, portfolios and corporate sites. …

Multicast DNS (mDNS) is a networking protocol designed to resolve hostnames to IP addresses within small networks, without the need for a local DNS server. It requires no configuration (zero-configuration) and uses the same programming interfaces, packet formats and operational semantics as unicast Domain Name System (DNS). It was designed to work as either a standalone protocol or alongside standard DNS servers. mDNS can work together with DNS Service Discovery (DNS-SD), a complementary zero-configuration networking technique specified separately in RFC 6763. …

A couple of months ago I moved the DHCP and DNS services to my home Linux router and left the Pi-Hole 5 service on a separate virtual machine. Despite everything working perfectly, I hit a snag: troubleshooting from PiHole is complicated because all DNS queries are resolved by the router and PiHole sees nothing. So I decided to redesign the setup. In this post I describe how I install Pi-Hole 6 on my Linux router so it provides DNS, DHCP (with dnsmasq) and ad sinkholing. This involves undoing the native dnsmasq installation. …

In this post I describe the process of installing a “Bitwarden” server. I’ve been using their Cloud service for several years, but I’ve decided to go with an on-premise home installation. While researching I discover with surprise that I have two options, the first is to use the official Bitwarden self-hosted (which consumes quite a few resources and seems complex) or go with a lightweight Vaultwarden, a clone of the former, which apparently installs quickly and is simple. …

In this post I describe how I’ve evolved my home DHCP and DNS server. Until now I had a PiHole dedicated on the network to DHCP, DNS and ad sinkhole. I’ve decided to migrate to a different configuration, move both DNS and DHCP services to the home router (Linux). I realized that when PiHole went down, the rest of the home services would spiral out of control, despite having the router and internet working, so I’m leaving PiHole exclusively as the ad sinkhole. …

In this post I explain how to control a PoE port on a TP-Link switch (TL-SG108PE) from Home Assistant. Since these small switches don’t support SNMP, I’ll use curl to authenticate, turn on, turn off or query the status of a specific port. The use case is being able to turn on or off a ReoLink PoE camera connected to one of the ports from Home Assistant. …
