Real-world IT skills built in the terminal.
No fluff. No paywalls on the fundamentals.
Hands-on labs that run on a $12/year VPS —
Linux, networking, cybersecurity, self-hosting.
What you get
Concepts you can actually use
Every lesson is built around a task a real sysadmin or security engineer does on the job. You learn by doing, not by watching slides.
Hands-on Labs
Step-by-step labs run on a cheap VPS. Read the concept, watch the screencast, do it yourself. Each lab builds toward a working production setup.
Cheat Sheets
Quick-reference command tables for Linux, SSH, networking, and cybersecurity — searchable, printable, and kept current.
Security-first mindset
Firewall config, HTTPS, hardening, and OSINT basics woven into every topic. Security isn't a separate course — it's how we do everything.
Labs
Get your hands dirty
Each lab is self-contained. Start anywhere, but Lab 01 is the foundation everything else builds on.
Lab 01 — Host Your First Website
Ubuntu, Nginx, DNS records, and Let's Encrypt. From a blank VPS to a live HTTPS site in one session.
Start lab →Lab 02 — Your Own VPN Server
Deploy OpenVPN on the same VPS from Lab 01. Understand what a VPN actually does at the packet level.
In progressLab 03 — Firewall with UFW
Configure ufw rules, default deny, allow specific services, and verify your posture with nmap.
In progressFree. Always.
The fundamentals stay free
Labs 01–03 and all cheat sheets are free, forever. Future paid bundles are extras, not paywalls.
