Installation procedure

Installation

$ sudo apt update
$ sudo apt upgrade
$ curl -L https://install.pivpn.io | bas

Generate key for the server

# Make a private key
$ wg genkey | sudo tee /etc/wireguard/server.key
$ sudo chmod 600 /etc/wireguard/server.key# Generate and save the public key from the private key.
$ sudo cat /etc/wireguard/server.key | wg pubkey | sudo tee /etc/wireguard/server.pub
$ sudo chmod 600 /etc/wireguard/server.pub

Generate key for client

# Make a private key
$ wg genkey | sudo tee /etc/wireguard/client.key
$ sudo chmod 600 /etc/wireguard/client.key# Generate and save the public key from the private key.
$ sudo cat /etc/wireguard/server.key | wg pubkey | sudo tee /etc/wireguard/client.pub…
