Welcome
This is my working knowledge base. It contains settings, checklists, configuration examples, and solutions to common tasks encountered in day-to-day system administration.
Everything here has been battle-tested in production. No guesswork or unverified advice.
Structure of Materials
The notes are organized using the digital garden principle — each topic is linked to others. Start with any area you need.
Main sections:
- Virtualization — installation and configuration of hypervisors
- Operating Systems — Linux and Windows Server
- Networking and Security — routing, VPN, firewalls
- Monitoring — setting up observation systems
- Automation — scripts and configurations
Note Types
I use several formats for convenience:
| Type | Description |
|---|---|
| Guide | Step-by-step instructions for installation and configuration |
| Checklist | A concise list of actions for quick deployment |
| Cheat Sheet | Commands and syntax for quick reference |
| Troubleshooting | Error description and how to fix it |
How to Use the Site
- Search — the fastest way to find the topic you need
- Tag navigation — grouping by technology
- Related notes — links to adjacent topics within the materials
Who Might Find This Useful
- System administrators working with a similar stack.
- Anyone using virtualization systems.
- Those looking for concise, no-fluff instructions.
How to Use This
The easiest way is to search. If you need a topic — just type a keyword.
You can start from any section. The materials are not arranged in a linear sequence — everyone decides what they need.
If a note helped you — great. If you spot an inaccuracy or know a more elegant solution — drop me a line, I’d be happy to discuss it.
The site is being updated gradually. Some materials come from my work notes, others have been specifically prepared for publication. If something is missing — it might appear later.
Happy configuring.
