Starting with networking and Linux before jumping to Nmap makes sense — the labs are the part I'd actually stick with.

Solid plan. Tip for week 1: after each lesson, prove it in a terminal. Run ss -tulpn, then nmap -sV on your own lab box, and match what you see to the TCP/IP theory. Hands-on labs at atomicai.ch/… if you want guided practice. What's your first lab?
