Creating video storage system [part2]
The part 2 will be the configuration of the production machine, the pi
Configuring Raspberry PI 3 with Raspbian Buster (Debian 10)
For the setup the pi, I will use a headless configuration of raspbian.
and these instructions headless pi setup
Once the flashing is complete we can login to the pi using this command from the terminal
Make sure you
upgrade the software otherwise the RSA algorithm might not be available on the client due to the server is using the latest version.
Also it is recommended to change the password or the pi user just in case 😉
sudo apt update -y sudo apt upgrade -y sudo passwd pi
Installing software on the pi
We will provision the pi by installing the following packages and enabling the
sudo apt install -y htop iftop iotop openvpn vim sudo modprobe tun
Once the packages are installed let’s run a trace route to see the current route of our internet connection.
Configuring the VPN software
To configure the VPN on the PI copy the certificates previously created under
/etc/openvpn/client/ and run
chmod -R 500 /etc/openvpn/client/
Then create a file to store the client configuration
sudo vim /etc/openvpn/client.conf
and add the below content replacing the
x.x.x.x by the actual IP of the OC
client tls-client remote-cert-tls server ca /etc/openvpn/client/ca.crt cert /etc/openvpn/client/vuser2.crt key /etc/openvpn/client/vuser2.key tls-crypt /etc/openvpn/client/devvpn.tlsauth proto tcp remote x.x.x.x 1194 tcp dev tun topology subnet cipher AES-256-CBC log /var/log/openvpn.log pull
and start the client
sudo systemctl start openvpn@client sudo systemctl enable openvpn@client
Once it is running you can see the new NIC
tun0 that show that the VPN is running
We can verify that it worked by running the trace route again
We can see that the internet connection of the VPN is fairly good to be free and almost unlimited (we can use up to 10TB of traffic monthly for free)

That is all for now the next part will be about the actual code implementation.
