# @file Linux OpenVPN / WireGuard Profiles
|
|
# @brief Installs both OpenVPN and WireGuard VPN profiles on Linux devices.
|
|
# @description
|
|
# This script installs OpenVPN and WireGuard VPN profiles. It does a few things to install the profiles and make sure
|
|
# they are usable by desktop users:
|
|
#
|
|
# 1. It ensures OpenVPN and `NetworkManager-*` plugins are installed (this allows you to see all the different VPN profile types available when you try to import a VPN profile on Linux devices)
|
|
# 2. Imports the OpenVPN profiles stored in `${XDG_CONFIG_HOME:-$HOME/.config}/vpn`
|
|
# 3. Applies the OpenVPN username and password to all the OpenVPN profiles (which can be passed in as `OVPN_USERNAME` and `OVPN_PASSWORD` if you use the environment variable method)
|
|
# 4. Bypasses the OpenVPN connection for all the networks defined in `.host.vpn.excludedSubnets` (in the `home/.chezmoi.yaml.tmpl` file)
|
|
# 5. Repeats the process for WireGuard by looping through all the `*.nmconnection` files stored in `${XDG_CONFIG_HOME:-$HOME/.config}/vpn` (username and password should already be stored in the encrypted files)
|
|
#
|
|
# ## Creating VPN Profiles
|
|
#
|
|
# More details on embedding your VPN profiles into your Install Doctor fork can be found by reading the [Secrets documentation](https://install.doctor/docs/customization/secrets#vpn-profiles).
