About fld.sh

This site documents real-world technical solutions and configurations from actual infrastructure work. What started as personal notes has evolved into a comprehensive resource covering Linux system administration, networking, storage management, and virtualization.

What You'll Find Here

The content focuses on practical, battle-tested approaches rather than theoretical concepts. If you work with Linux servers, storage systems, or network infrastructure, you'll find actionable guides covering:

  • Gentoo Linux - Installation, optimization, package management, and system customization for this source-based distribution
  • ZFS Storage - Filesystem management, snapshots, compression, pool configuration, and data protection strategies
  • Networking - IP addressing, VLANs, VPN configuration, subnet management, interface setup, and network troubleshooting
  • SSH Configuration - Key management, authentication, security hardening, and remote access best practices
  • Incus Containers - Container management, orchestration, networking, and deployment strategies
  • Virtualization - VM management, resource allocation, and hypervisor configuration
  • Shell Scripts - Automation utilities and practical scripting examples
  • Cheatsheets - Quick reference guides for essential commands and operations

Privacy and Performance

Unlike most technical blogs, this site respects your privacy. There are no advertising networks, no paywalls, and no surveillance capitalism. Analytics are handled by self-hosted Matomo with DoNotTrack enabled, ensuring visitor data stays private and is never sold to third parties. The site is built using Eleventy (11ty), generating static pages that load quickly and minimize server attack surface.

Every page is self-contained HTML with minimal JavaScript. This approach improves load times, reduces hosting costs, and eliminates entire categories of security vulnerabilities common in dynamic content management systems.

Why These Topics?

The posts reflect years of hands-on infrastructure work - setting up dedicated servers, managing storage pools, debugging network configurations, and automating system administration tasks. These aren't sanitized tutorials; they're documentation of actual solutions to real problems, including the mistakes and iterations along the way.

Topics like IP address range selection, dedicated server setup, and VLAN configuration come directly from production deployments. The ZFS reference material and network scanning guides are the documentation I wish existed when I started.
