In an earlier post, we covered Deploying a Public Vaultwarden Instance on a Proxmox LXC Container Using HAProxy on pfSense. While that architecture served us well, running a critical service like a password manager on a single node introduces a single point of failure. This guide represents the evolution of that setup. We are deploying…

Monitoring Proxmox VE using Zabbix Agent
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…

Encrypting Zabbix Server communication with Agents using Let’s Encrypt certificates
If you have deployed Zabbix Server on your Proxmox infra structure, you might be interested in hardening Zabbix installation with SSL certificates for the web frontend. You might also be interested in encrypting communication between Zabbix Server and the other Zabbix components, such as Agents and Proxies, after all, although it is just monitoring information,…
