Secure Shell (SSH)
SSH is a very common and secure way to access your Raspberry Pi's command line from another computer. It's like typing commands directly on the Pi, but you are doing it from somewhere else. This is great for managing files, running programs, or checking system status. Most Raspberry Pi operating systems come with SSH enabled, or it's very easy to turn on, which is convenient, actually.
To use SSH remotely, you usually need to know your home network's public IP address and set up something called "port forwarding" on your router. Port forwarding tells your router to send SSH traffic from the internet to your Pi. This can be a bit tricky for beginners, but there are many guides online to help, which is nice, pretty much.
While SSH is secure for the connection itself, exposing your Pi directly to the internet through port forwarding does carry some risk. It's always a good idea to use strong, unique passwords or, even better, SSH keys for extra security. This helps keep unwanted people out of your system, which is very important, obviously.
Virtual Private Networks (VPN)
A VPN creates a secure, encrypted tunnel between your remote device and your home network. When you connect to your home VPN, your remote device acts as if it's physically on your home network. This means you can access your Raspberry Pi and any other devices on your network as if you were sitting right next to them, which is pretty cool, in a way.
Setting up a VPN server on your Raspberry Pi is a very secure way to get remote access. OpenVPN and WireGuard are two popular free and open-source VPN solutions that you can install on your Pi. They might take a little more effort to configure than simple port forwarding, but the added security is often worth it, you know, for your peace of mind.
With a VPN, you don't need to open specific ports for each service on your router. You just open one port for the VPN, and then all your traffic through that tunnel is secure. This makes your home network much safer from outside threats, and that's a big plus, essentially.
Tunneling Services Like Ngrok
If setting up port forwarding or a VPN sounds too complicated, services like Ngrok offer a simpler way to expose your local services to the internet. Ngrok creates a secure tunnel from their cloud service to your Raspberry Pi, giving you a public URL that points directly to your Pi, so, it's pretty direct.
