Private PyPI with Docker Compose on RHEL 8.10

Thiago Crepaldi — Thu, 16 Apr 2026 20:49:25 +0000

For developers managing internal libraries or AI infrastructure, a private PyPI server is essential for hosting nightly builds without polluting public registries. devpi is the gold standard for this, specifically for its “volatile” index feature which allows for rapid iteration. In this guide, we’ll deploy it on RHEL 8.10 using Docker Compose, rooting everything in...

Troubleshooting “Failed” pfSense+ Upgrades on Netgate Hardware

Thiago Crepaldi — Sat, 04 Apr 2026 04:25:10 +0000

The Disk Space Wall Updating your firewall is usually a “set it and forget it” task, but if you’re running a high-performance appliance like the Netgate 6100, you might occasionally hit a wall. In my case, I triggered the update from 25.x to 26.03, the logs start rolling, and then—Failed. If your logs mention cloning...

How to Natively Run Prometheus Plex Exporter on Proxmox LXC and Import on Grafana

Thiago Crepaldi — Sun, 28 Dec 2025 16:02:19 +0000

If you are running a homelab like mine, you probably rely heavily on Proxmox to manage your infrastructure. I recently deployed a monitoring stack using Prometheus and Grafana within a lightweight LXC container, which I will post more about later. Everything was working perfectly until I decided to add metrics for my Plex Media Server....

No-IP is a simple and free Dynamic DNS (aka DDNS) service that is supported as a custom configuration on your Unifi Dream Router (aka UDR), but still very stable and easy to get it running with the right steps. Although I have mentioned this tutorial is meant for the Unifi dream Router, it should also...

Overriding external domains DNS Bind9’s Response Policy Zone on your pfSense

Thiago Crepaldi — Sat, 18 Mar 2023 05:15:52 +0000

On a previous post, we’ve discussed how to use Bind9 on your pfSense in a way that external names were forwarded to name servers while internal names were statically resolved by Bind. In this post, we are going to discuss how to override the IPs returned by external name servers with IPs of our choosing....

Configuring DHCP Dynamic Host registration on DNS Bind9 on your pfSense

Thiago Crepaldi — Sat, 18 Mar 2023 04:51:28 +0000

On a previous post, we’ve discussed how to use Bind9 on your pfSense in a way that external names were forwarded to other name servers and internal names were statically resolved. In this post, we are going to integrate pfSense’s DHCP Server and Bind9, so that when DHCP assigns an IP to a device, it...

Configuring DNS Bind9 on your pfSense

Thiago Crepaldi — Sat, 18 Mar 2023 04:11:48 +0000

If there is one annoying thing on pfSense that seems to be never fixed is its DNS Resolver service called Unbound. Release after release, the Netgate folks still struggle to identify and fix the random crashes, unexpected restarts and whatnot. In this post, we are going to install Bind9, a very solid DNS server, to...

Monitoring Speedtest on LAN using iPerf3 on Zabbix Agent

Thiago Crepaldi — Tue, 03 Jan 2023 19:26:15 +0000

From previous posts, we have deployed Zabbix Server on a Proxmox container. We also hardened the installation through Let’s Encrypt certificates for the web frontend and TLS encryption for the communication between Server and Agents/Proxies, after all, although encrypted Zabbix Server <-> Agent/Proxy communication with PSK or SSL certificates 🙂 In this post I will...
