Networking and servers

Run web servers and network services.

📖 Key ideas

Find the IP with hostname -I.
Host a web server with Flask, Nginx or Apache.
Run services: Pi-hole (ad blocking), Home Assistant, file server (Samba), media server.
Use SSH keys and change default passwords.
Port forwarding exposes services to the internet (use carefully).

💡 Real-life example: A Pi server is a tiny shop on your home network, open for devices to visit.
