I recently decided to try out Windscribe, although they currently don’t have an app for Arch Linux. They offer OpenVPN, IKEv2 and WireGuard configuration files. I have always used OpenVPN but this time, I wanted to try WireGuard, a fairly new protocol that promises to be simpler, more secure, and faster than the alternatives. All the guides I found were about setting up a home VPN server with WireGuard, however, connecting to a VPN provider is much simpler. I am writting this as a reference note in case I have to set it up again, and if I can help someone else, all the better.
Wireguard installation
The official installation page has the instructions on how to download it in many operating systems. In my case, it is: sudo pacman -S wireguard-tools.
Connecting to a VPN
After getting the WireGuard configuration files from the Windscribe website, move this file to /etc/wireguard and you will probably need to rename it because the maximum length of a Linux interface name seems to be 15 characters, for example: sudo mv Windscribe-Copenhagen-LEGO.conf /etc/wireguard/copenhagen.conf.
Once this is done, you are ready to connect to the server, do it by simply running the command: sudo wg-quick up copenhagen, and to disconnect, you can use: sudo wg-quick down copenhagen.
⚠ INFO: If you are getting something like:
/usr/bin/wg-quick: line 32: resolvconf: command not found
On Arch Linux, you will need to install the systemd-resolvconf package.
On Debian, you will need to install the openresolv package.
Finally, if you want to configure the VPN interface to be persistent across reboots, you can do so by enabling it as a service with: sudo systemctl enable wg-quick@copenhagen.
