Networking and Remote Access

10 Lektionen in dieser Stufe

1. IP Addresses, Routers and DNS in Plain Terms
   Explain what an address, a subnet, a gateway and a name server do. · Lab: Draw your home network and write the address of your router, your laptop and your Pi on it.
2. Connecting to Wi-Fi and Ethernet with NetworkManager
   Manage connections on Bookworm with nmcli and nmtui. · Lab: List networks with nmcli, join one from the terminal and compare Wi-Fi and Ethernet details.
3. Finding Your Pi on the Network by Hostname and mDNS
   Reach a Pi by name instead of hunting for its address. · Lab: Set a hostname, then ping hostname.local from another computer and look it up on the router.
4. Testing Connections with ping, ip and ss
   Check link, address, route and listening ports in a fixed order. · Lab: Work through a four-step checklist on a deliberately misconfigured connection.
5. Logging In Remotely with SSH
   Open a secure shell from Windows, macOS or Linux and work on the Pi. · Lab: Enable SSH, log in from another computer and run the Level 2 report script remotely.
6. Passwordless Login with SSH Key Pairs
   Create a key pair, install the public key and understand what stays private. · Lab: Generate an ed25519 key, copy it with ssh-copy-id and log in without a password.
7. Copying Files Across the Network with scp and rsync
   Transfer single files and keep whole folders in sync. · Lab: Push a folder to the Pi with rsync, change two files and watch only those two transfer.
8. Setting Up a Headless Pi with No Monitor
   Prepare a card so a Pi joins Wi-Fi and accepts SSH on first boot. · Lab: Flash a Zero 2 W (or your main Pi) with preset Wi-Fi and SSH and reach it without ever attaching a screen.
9. Remote Desktop Options: VNC and Raspberry Pi Connect
   Reach the graphical desktop from another device on and off your network. · Lab: Enable VNC on Wayland, connect from a laptop, then try screen sharing through Raspberry Pi Connect.
10. Reserving a Fixed Address for a Pi
    Give a Pi a predictable address by router reservation or a static profile. · Lab: Create a DHCP reservation, or a static nmcli profile, and confirm it survives two reboots.

Abschlussprojekt
