Every time a device on your network loads a website, streams media, or executes an API call, it issues a Domain Name System (DNS) query. While modern ad-blocking tools such as standalone Pi-hole or AdGuard Home effectively filter telemetry endpoints…
In modern homelabs, staging clusters, and internal enterprise architectures, running services over unencrypted HTTP is an unacceptable security hazard. However, securing private internal hostnames (such as *.internal, *.lan, or non-public subdomains) with public certificate authorities like Let’s Encrypt presents formidable…
In modern infrastructure engineering and homelab administration, data loss is a certainty if you operate long enough. Hardware drives suffer silent bit rot, ransomware attacks encrypt container volumes, database schema migrations corrupt tables, and human errors trigger accidental deletions. While…
Modern organizations, legal teams, healthcare providers, and privacy-conscious homelab administrators routinely handle sensitive documents in Portable Document Format (PDF). From corporate balance sheets and employment agreements to medical records and tax filings, PDFs represent the lifeblood of institutional records. Yet…
As self-hosted infrastructure expands, managing independent user credentials across dozens of containerized services—such as Grafana, Portainer, Proxmox, and internal microservices—rapidly introduces credential sprawl and severe security vulnerabilities. Many homelab and internal applications either lack native Multi-Factor Authentication (MFA), rely on…
Eliminate DNS as a single point of failure in your homelab or office. Deploy dual AdGuard Home instances with Keepalived Virtual IP failover and automated configuration synchronization in Docker.
The OpenZFS filesystem has long been revered as the gold standard in enterprise storage, combining copy-on-write integrity, pooled storage management, and near-instantaneous atomic snapshots. However, snapshots by themselves do not constitute a backup. A local snapshot stored on the same…
Connecting to homelab hardware, internal office servers, and private hypervisor consoles while traveling typically requires maintaining a complex VPN gateway like OpenVPN or standard WireGuard. However, running traditional point-to-site VPNs forces administrators to open public firewall ports, manage dynamic DNS…
Exposing web applications, self-hosted dashboards, and API microservices to the public internet inevitably attracts an endless barrage of automated reconnaissance scanners, credential stuffers, and exploit payloads. While traditional perimeter firewalls and basic rate limiters offer minimal resistance against distributed botnets,…
Automate K3s etcd snapshots and stream backups to S3 object storage for disaster recovery. Step-by-step tutorial covering cron scheduling, on-demand snapshots, and full cluster restore.
