Yes, Pi prices have gone up, as have requirements for hosting a few services. I already found myself migrating off my original Pi, and even my Intel NUC device as a home server.
It is worth keeping in mind what your requirements are vs the total cost of ownership.
How to set up a VPN server on Raspberry Pi easily in 30 minutes
Imagine this: you’re at a coffee shop, sipping a latte, and you suddenly realize you need a super important file you left on your home computer. Normally, you’d panic. But not you. You just fire up a connection on your laptop, and boom, you’re securely browsing your home PC’s files as if you were sitting right in front of it.
Or maybe you’re traveling and want to check your home security cameras without worrying about that sketchy hotel Wi-Fi. This isn’t some expensive subscription service with a questionable logging policy. This is something you built yourself with a tiny, credit-card-sized computer.
Learning how to set up a VPN server on a Raspberry Pi isn’t just a fun tech project; it’s a powerful move to reclaim full control over your digital security. In an era of endless monthly fees and data logging concerns, a self-hosted VPN offers a transparent and incredibly cost-effective alternative. It ensures that you are the sole controller of your data, creating an encrypted tunnel straight to your trusted home network, no matter where you are in the world.
I’ve built a lot of DIY servers, and I’ve seen this tiny computer become a true privacy fortress. It’s not just for networking experts; it’s for anyone ready to take charge of their online safety.
Why build your own Raspberry Pi VPN server?
So, with dozens of commercial VPN services out there, why bother setting up your own? The answer comes down to three powerful benefits: cost, control, and capability.
First, let’s talk about the money. Most popular VPN services charge a recurring fee, which can add up to hundreds of dollars over a few years. A Raspberry Pi is a one-time purchase. Think of it as buying your own high-quality coffee machine instead of paying for a pricey latte every single day. The initial investment pays for itself incredibly quickly.
Next, and for me, the most important part: privacy. When you use a commercial VPN, you’re trusting a company’s “no-logs” promise. With a Pi VPN, you don’t need to trust anyone. You own the entire system. Your data travels from your device, through an encrypted tunnel you created, directly to your home connection. No third-party company ever sees it.
Finally, it’s a gateway to your digital home. I’ll never forget the first time I traveled after setting up my Pi VPN. I was in a hotel across the country and realized I’d left a crucial file on my home computer. Instead of panicking, I fired up the VPN on my laptop. A few clicks later, I was securely accessing files on my home PC and my NAS (Network Attached Storage) as if I were sitting right there. That feeling of self-reliance is priceless.
What you’ll need: The complete project checklist
Great projects start with great preparation. Think of this like gathering all your ingredients before you start cooking. Having everything on hand makes the entire process smoother.
Essential Hardware
A Raspberry Pi board: I strongly recommend a Raspberry Pi 4 or Raspberry Pi 5. Their processing power means your VPN will be fast and responsive. My current setup on a Pi 5 handles video calls and file downloads simultaneously without breaking a sweat.
A high-quality microSD card: This is your Pi’s hard drive, so don’t skimp here. You’ll need at least 16GB, but a 32GB Class 10 card is the sweet spot.
The correct power supply: This is critical. A Pi 4 or 5 needs a good USB-C power adapter. Using an old phone charger is a recipe for random crashes and data corruption.
An Ethernet cable: While the Pi has Wi-Fi, a server needs stability. A wired Ethernet connection is like a private highway for your data, free from interference.
A case (optional, but highly recommended): A simple case protects your Pi. Many also come with a fan or heatsinks to keep your little server cool.
Required Software
Raspberry Pi Imager: This is the official, free tool. It’s the easiest and most reliable way to install the operating system onto your microSD card.
An SSH client: SSH (or Secure Shell) is a magical tool that lets you command your Raspberry Pi from your main computer. This means you don’t need a separate keyboard, mouse, or monitor for your Pi. For Windows, use PuTTY. For macOS and Linux, the Terminal app is already built in.
Phase 1: Preparing your Raspberry Pi
With all our components gathered, it’s time to lay the foundation. We’ll be using Raspberry Pi OS Lite. It doesn’t have a graphical desktop, which is perfect for a server because it uses fewer resources.
Install Raspberry Pi OS Lite: Open the Raspberry Pi Imager. Choose the OS: Raspberry Pi OS (other) > Raspberry Pi OS Lite (64-bit).
Configure Advanced Options: This is the pro-tip. Before clicking Write, click the Settings cog icon. Check the box to Enable SSH and set your username and password.
Write the OS: Click Write. Once it’s finished, eject the card, insert it into your Pi, plug in the Ethernet cable, and then connect the power.
First Boot and SSH: Find your Pi’s IP address from your router’s admin page. Then, open your SSH client (Terminal or PuTTY) and type ssh your_username@your_pi_ip_address. Enter your password.
Update Your System: Welcome to your server’s command line! You must run updates.
sudo apt update
sudo apt full-upgrade
Phase 2: How to set up a VPN server with PiVPN
Now for the main event. We’re using a brilliant tool called PiVPN, which automates the entire complex process.
The One-Command Installation On your Pi’s command line, run this single command: curl -L https://install.pivpn.io | bash
This will launch a blue, text-based wizard. Here are the choices I recommend:
Protocol: Choose WireGuard. It’s newer, significantly faster, and more efficient, which is perfect for the Pi. WireGuard is the superior choice for 99% of home users.
Port: Just accept the default (51820). Make a note of this.
DNS Provider: Choose a privacy-focused one like Cloudflare (1.1.1.1) or Quad9.
DDNS Setup: Choose Yes. This is crucial. Your home’s public IP address can change. A DDNS service (like the free DuckDNS) gives you a permanent, memorable address (like my-safe-pi.duckdns.org) that always points to your home, no matter what your IP is.
Unattended Upgrades: Select Yes. This enables automatic security updates for your Pi.
After it finishes, reboot your Pi.
Phase 3: Configuring your network
Our server is running, but the outside world can’t reach it yet. We need to tell your router how to handle the traffic.
Set a Static IP for your Pi: Log in to your router’s admin page. Look for “DHCP Reservation” or “Address Reservation.” Find your Raspberry Pi in the list of devices and click “Reserve.” This ensures your Pi always has the same local IP address (e.g., 192.168.1.123). Never skip this step.
Port Forwarding: Now, find the “Port Forwarding” or “Virtual Servers” section in your router settings. Create a new rule:
Service Name: WireGuard-VPN (or anything)
Internal IP: The static IP you just reserved for your Pi.
External Port: 51820
Internal Port: 51820
Protocol:UDP (WireGuard uses UDP, not TCP)
Save the rule. Your router will now forward all WireGuard traffic to your Pi.
The Final Steps: Connecting Your Devices
This is the most satisfying part. We just need to create the “keys” for your devices.
Create a Client Profile On your Pi’s command line (via SSH), use this simple command: pivpn add
It will ask for a name. Type something descriptive, like my-iphone or work-laptop, and press Enter. That’s it!
Connect Your Phone (The Easy Way)
On the Pi, run this command (using the name you just created): pivpn -qr my-iphone
A giant QR code will appear in your terminal.
On your phone, download the official “WireGuard” app.
Open the app, tap the + button, and choose Create from QR code.
Scan the code. It will import everything.
Toggle it on. You’re connected!
Connect Your Laptop
On the Pi, you’ll find a new file in the /home/your_username/configs directory (e.g., my-iphone.conf).
Securely transfer this file to your computer.
Download the official WireGuard app for Windows or macOS.
Click Import tunnel(s) from file and select the .conf file.
Click Activate.
You’re done. You’ve built a personal security powerhouse. That feeling of self-reliance? Priceless.
Happy #MakerMonday to everyone! This week, we’re excited to showcase an innovative project from Raspberry Pi Official Magazine: Edgeberry. As the name suggests, it’s a modular expansion system designed to transform your Raspberry Pi into a robust and adaptable Internet of Things (IoT) edge device – a particularly useful tool for streamlining development workflows.
At Raspberry Pi, we’ve consistently strived to create exceptional general-purpose computing platforms suitable for a vast range of applications, all while maintaining an accessible price point. This commitment extends beyond the initial purchase; it involves designing products built for longevity and supported by a supply chain that is both ethically responsible and environmentally sustainable. A…
The world of robotics and autonomous systems stands on the precipice of a significant shift, and it’s largely thanks to advancements in computer vision. If you’ve ever wished your Raspberry Pi projects could see faster, smarter, and with far less power, we’ve found something that might be exactly what you need. Prophesee has launched the GenX320 Starter Kit for Raspberry Pi 5, bringing their…
Sentient 12.1” test cycle. Pushed a desktop image through the Pi so visitors can glimpse what sits behind the black glass — the cage, the Pi, the HDMI-to-AV adapter — a little mise en abyme for the Interpreter’s working parts. A screen showing the screen’s own spine.
The Interpreter boot sequence continues—now with its brain (Raspberry Pi) housed in a red-and-white cage, quite literally. The Sentient screen is alive, receiving signal through HDMI > RCA > BNC, though overscan issues still distort the margins—an apt visual for a system struggling to frame the world clearly.
Installed VOSK for local speech-to-text, and despite the model inflating cleanly, the handheld mic couldn’t make itself heard. Too quiet. Not enough signal. A frustratingly familiar diagnosis for anyone with auditory processing disorder: the sound exists, but it fails to resolve.
Tried to initiate communication with the Dynafax modem next, but… crossed wires. TX/RX confusion. Another metaphor embedded in a literal serial mismatch. A null modem adapter is now en route.
A USB mic has also been ordered, to be repositioned at the front of the cage with a ↯ VOICE IN label—turning input into ritual, presence into symbol.
Still to test the OKI ML3320 dot matrix and Epson thermal receipt printer. No doubt more static, more negotiation ahead. But the friction is the point. These misfires, misalignments, and workarounds are exactly what the Interpreter project is about—parsing broken speech, translating ghost signals, and making glitch into grammar.
In meinem letzten Beitrag habe ich gezeigt, wie man mit XSLT und Apache FOP aus Wetterdaten automatisch ein grafisches Dashboard generiert. Damit dieses Bild regelmäßig und automatisch erzeugt wird – zum Beispiel stündlich oder einmal täglich – eignet sich ein CronJob auf dem Raspberry Pi perfekt. In diesem Beitrag zeige ich dir, wie du mit einem Bash Script, einem passenden CronJob und deinem Raspberry Pi eine solche Automatisierung realisierst. https://youtu.be/wsOeFisDvNY
Was ist ein CronJob?
Ein CronJob ist ein zeitgesteuerter Task unter Unix/Linux-Systemen. Er erlaubt es dir, Skripte oder Programme zu festen Zeitpunkten automatisch auszuführen – zum Beispiel jeden Tag um 6 Uhr oder alle 15 Minuten. Das macht Cron zu einem perfekten Werkzeug für wiederkehrende Aufgaben wie das Generieren von Reports oder – in unserem Fall – das Erstellen eines Wetter-Dashboards. Aufbau eines CronJob-Patterns Ein CronJob besteht aus einem zeitlichen Ausdruck (Pattern) und dem Befehl, der ausgeführt werden soll. Das Pattern besteht aus fünf Feldern, die wie folgt interpretiert werden: Aufbau eines CronJob-Patterns Beispiel: 0 6 * * * /home/pi/xml2weatherpng/templating/transform.sh → führt das Skript jeden Tag um 6:00 Uhr morgens aus. Zugriff auf die Crontab Um einen CronJob auf dem Raspberry Pi (oder einem anderen Linux-System) einzurichten, verwendet man die sogenannte Crontab – das ist die Konfigurationsdatei, in der geplante Aufgaben definiert werden. Du gelangst zur Crontab über das Terminal mit folgendem Befehl: crontab -e Beim ersten Aufruf wirst du möglicherweise aufgefordert, einen Editor auszuwählen (z. B. nano, vim, mcedit). Für Einsteiger empfiehlt sich nano, da er leicht zu bedienen ist. CronTab - Auswahl des Editors Nach der Auswahl öffnet sich die Crontab-Datei im gewählten Editor. Hier kannst du neue Zeilen hinzufügen, um Jobs zeitgesteuert auszuführen. CronTab im Editor Nano Beispiel für einen Eintrag: 0 * * * * /home/pi/wetterdashboard/transformXML2PNG.sh Dieser Job würde das Bash-Script stündlich zur vollen Stunde ausführen. Wichtig: - Jeder Benutzer hat seine eigene Crontab. Wenn du z. B. als pi angemeldet bist, gilt die Crontab nur für diesen Nutzer. - Der vollständige Pfad zur Datei ist zwingend notwendig. - Falls Umgebungsvariablen (wie PATH) im Script verwendet werden, empfiehlt es sich, diese im Script selbst korrekt zu setzen oder absolute Pfade zu verwenden.
Git Repository klonen ins Home-Verzeichnis
Öffne ein Terminal auf deinem Raspberry Pi. Wechsle in dein Home-Verzeichnis (optional, falls du nicht schon dort bist): cd ~ Klonen des Repositories: git clone https://github.com/StefanDraeger/xml2weatherpng.git Nach dem Ausführen befindet sich das Repository unter: /home//xml2weatherpng Dort kannst du anschließend dein meteomatic_fetch.sh-Script ausführen oder für den CronJob hinterlegen. Projekt xml2weatherpng auf dem Pi
Berechtigungen für meteomatics_fetch.sh setzen
Nachdem du das Repository mit git clone auf deinen Raspberry Pi geladen hast, fehlt dem Bash-Skript standardmäßig oft die Ausführungsberechtigung. Um das Skript ausführbar zu machen, musst du einmalig folgende Zeile ausführen: chmod +x meteomatics_fetch.sh Anschließend lässt sich das Skript wie gewohnt starten: Hier ist ein passender Abschnitt für deinen Blogbeitrag, in dem du erklärst, wie FOP auf dem Raspberry Pi heruntergeladen und entpackt wird:
Apache FOP auf dem Raspberry Pi installieren
Damit das Bash-Skript später aus den XML- und XSL-Dateien eine PNG-Datei erzeugen kann, benötigen wir Apache FOP. Dieses Tool kannst du direkt mit wget herunterladen: wget –content-disposition https://www.apache.org/dyn/closer.cgi?filename=/xmlgraphics/fop/binaries/fop-2.11-bin.zip -O fop-2.11-bin.zip Apache FOP download mit wget Anschließend entpackst du das ZIP-Archiv mit: unzip fop-2.11-bin.zip Anschließend muss der Ordner fop im entpackten Verzeichniss fop-2.11 eine Ebene nach oben verschoben werden (oder man passt alternativ die Pfade in den Bash Scripts an): cd fop-2.11 mv fop ../ verschieben des Ordners fop auf dem Pi Java JDK installieren Bevor Apache FOP auf dem Raspberry Pi genutzt werden kann, muss eine Java-Laufzeitumgebung installiert werden. Apache FOP basiert auf Java und benötigt daher ein entsprechendes JDK (Java Development Kit). 1. System aktualisieren Es empfiehlt sich, das System vor der Installation zu aktualisieren, um sicherzustellen, dass alle Paketquellen aktuell sind: sudo apt-get update sudo apt-get upgrade 2. OpenJDK installieren Anschließend installierst du das OpenJDK – die freie Referenzimplementierung von Java: sudo apt install default-jdk install default-jdk auf Pi Dabei wird aktuell (Stand Juni 2025) OpenJDK 17.0.15 installiert, was vollständig kompatibel mit Apache FOP ist. 3. Version prüfen Ob die Installation erfolgreich war, kannst du mit folgendem Befehl prüfen: java -version installiertes Open JDK 17 auf dem Pi Mit einem aktuellen und funktionierenden Java-Setup kannst du im nächsten Schritt Apache FOP herunterladen und einsetzen. Wetterdaten abrufen und PNG erzeugen Sobald Apache FOP korrekt eingerichtet und das Java JDK installiert ist, kann das vorbereitete Bash-Script ausgeführt werden. Dieses ruft die Wetterdaten im XML-Format von Meteomatics ab und erzeugt daraus mithilfe von XSLT und FOP eine PNG-Grafik für das ePaper-Display. Führe dazu einfach folgenden Befehl aus: ./fetch_weatherdata.sh Das Script erledigt automatisch folgende Schritte: - Download der aktuellen Wetterdaten (im XML-Format) - Transformation per XSLT in ein XSL-FO-Dokument - Generierung des fertigen PNG-Bildes mit Apache FOP Das Ergebnis findest du anschließend im Verzeichnis output/ – z. B.: output/forecast.png Dieses Bild kann dann direkt auf einem Display dargestellt oder weiterverwendet werden. abrufen der Wetterdaten sowie transformieren der XML Datei in ein PNG mit Apache FOP
Bereitstellung des PNG-Bildes über einen HTTP-Server
Da sich das erzeugte Bild nun lokal auf dem Raspberry Pi befindet, muss es über einen HTTP-Server bereitgestellt werden, damit beispielsweise ein ESP32-ePaper-Display es abrufen und darstellen kann. Bild vom Raspberry PI im Browser Ein einfacher Weg ist die Nutzung von Python, da auf den meisten Systemen bereits eine Python-Installation vorhanden ist: cd output/ python3 -m http.server 8080 Dieser Befehl startet einen kleinen lokalen Webserver auf Port 8080, der das aktuelle Verzeichnis (output/) bereitstellt. Das PNG-Bild kann dann über folgende URL abgerufen werden: http://:8080/forecast.png Ersetze durch die tatsächliche IP deines Raspberry Pis im Netzwerk. Diese findest du mit dem Befehl: hostname -I HTTP-Server automatisch starten mit tmux und CronJob Im vorherigen Abschnitt habe ich gezeigt, wie man mit python3 -m http.server schnell und unkompliziert das generierte Wetterbild im Netzwerk verfügbar macht. Doch nach einem Neustart des Raspberry Pi ist der Server wieder beendet – das ist natürlich nicht gewünscht. Um sicherzustellen, dass der HTTP-Server automatisch beim Systemstart gestartet wird, nutzen wir eine Kombination aus: - dem Terminal-Multiplexer tmux, der den Serverprozess im Hintergrund dauerhaft laufen lässt, - einem CronJob mit @reboot, der die tmux-Sitzung beim Hochfahren automatisch startet. Schritt 1: Webserver-Befehl in tmux starten (manuell testen) Du kannst testen, ob der Server wie gewünscht läuft: tmux new -s webserver ‘cd ~/xml2weatherpng/output && python3 -m http.server 8080’ Schritt 2: Automatischen Start per CronJob konfigurieren Öffne die Crontab deines Benutzers: crontab -e Füge am Ende folgende Zeile hinzu: @reboot tmux new -d -s webserver 'cd /home//xml2weatherpng/output && python3 -m http.server 8080’ 🔁 Der Parameter -d sorgt dafür, dass tmux die Sitzung im Hintergrund startet – du musst dich also nicht einloggen. Ergebnis Nach einem Neustart des Raspberry Pi wird der kleine Webserver automatisch gestartet und stellt das aktuelle PNG bereit – ganz ohne manuelles Zutun.
