How to choose, use and configure a VPN in Daphile (Guide)

Why Daphile Needs a Special VPN Approach

Daphile is a minimal, audio-optimized Linux distribution designed to turn any PC into a high-fidelity music server. It boots from USB or internal storage into a read-only root filesystem, exposes a web-based control interface (no native desktop environment), and doesn’t include a traditional package manager like apt or yum. Instead it uses an overlay filesystem in RAM and a simple plug-in mechanism for extensions.

Typical Daphile users are audiophiles who value bit-perfect playback, low latency and low noise. They rarely log in via console, and there’s no GNOME/KDE/Xfce to click your way to Software Updates. Any additional software—such as a VPN client—must either be provided as a Daphile plug-in, a static binary or an init script that loads at each boot from persistent storage.

Because of these technical peculiarities, the best VPNs for Daphile are those that:

Offer static OpenVPN or WireGuard binaries that run without system-level package dependencies.
Provide manually downloadable configuration files so you can drop them into persistent storage.
Support WireGuard for reduced overhead, or OpenVPN for maximum compatibility.
Include clear documentation for headless or CLI-only environments.

1. Installing and Configuring Mullvad on Daphile

Mullvad is ideal because it provides standalone WireGuard and OpenVPN binaries. You’ll need a persistent partition (e.g. /mnt/store) to hold your VPN tools and configs. The following assumes you have SSH access to Daphile and a writeable store at /mnt/store.

Download Mullvad’s static OpenVPN tarball and WireGuard binary:

wget -O /mnt/store/mullvad-openvpn.tar.gz https://mullvad.net/download/openvpn/mullvad-latest-openvpn.tar.gz
wget -O /mnt/store/wg https://mullvad.net/download/wireguard/mullvad-wireguard-linux-x64
chmod  x /mnt/store/wg

Extract the OpenVPN files:

tar xzf /mnt/store/mullvad-openvpn.tar.gz -C /mnt/store
# You’ll find .ovpn files under /mnt/store/openvpn

Place your Mullvad account token or number in a file:

echo mullvad_account_number_here > /mnt/store/mullvad-account.txt

Create a simple connect script at /mnt/store/connect-mullvad.sh:

#!/bin/sh
# Kill any existing
killall openvpn 2>/dev/null
# Start OpenVPN
openvpn --config /mnt/store/openvpn/us-sea-wireguard.ovpn 
        --auth-user-pass /mnt/store/mullvad-account.txt 
        --daemon
# Alternatively, WireGuard:
# wg-quick up /mnt/store/wg-us-sea.conf

Make it executable:

chmod  x /mnt/store/connect-mullvad.sh

Hook it into boot by adding to /etc/rc.local (Daphile’s init script):

# At end of /etc/rc.local before exit 0
sh /mnt/store/connect-mullvad.sh

On next reboot, Mullvad will start automatically. You can verify with ifconfig or wg show over SSH.

2. Installing and Configuring ProtonVPN on Daphile

ProtonVPN offers manual OpenVPN files and a lightweight CLI client in a tar archive. We’ll use the raw OpenVPN approach for simplicity.

Download ProtonVPN’s ZIP of OpenVPN config files:

wget -O /mnt/store/protonvpn-config.zip https://protonvpn.com/download/ProtonVPN_Configs.zip
unzip /mnt/store/protonvpn-config.zip -d /mnt/store/protonvpn

Create your credentials file:

echo username > /mnt/store/pvpn-userpass.txt
echo password >> /mnt/store/pvpn-userpass.txt
chmod 600 /mnt/store/pvpn-userpass.txt

Fetch or install an OpenVPN binary. If Daphile doesn’t already provide it, use a static build from OpenVPN releases and place it in /mnt/store, then chmod x it.
Create the connect script /mnt/store/connect-proton.sh:

#!/bin/sh
killall openvpn 2>/dev/null
openvpn --config /mnt/store/protonvpn/US East/washington.ovpn 
        --auth-user-pass /mnt/store/pvpn-userpass.txt 
        --daemon

Make it executable and add to /etc/rc.local:

chmod  x /mnt/store/connect-proton.sh
# in /etc/rc.local
sh /mnt/store/connect-proton.sh

Reboot, then SSH in and check ifconfig to see your new tun0 interface. Now your Daphile music server streams through ProtonVPN.

Conclusion

Whether you choose Mullvad for its WireGuard support and static binaries, or ProtonVPN for its rock-solid OpenVPN approach, both adapt nicely to Daphile’s minimalist, web-controlled architecture. By keeping everything in a writeable store partition and hooking into /etc/rc.local, you’ll have a sound-quality-focused media server protected by a reliable VPN tunnel.
