Step‑by‑Step Instructions
1. System Preparation
Before you begin, make sure your Linux distribution is up to date. Run:
sudo apt update && sudo apt upgrade -y
Updating your system ensures all dependencies required for Proton VPN CLI install are available and that you’re running a stable kernel. If you’re on a Red Hat or CentOS system, replace apt with yum or dnf accordingly.
For Proton VPN command line setup, you’ll also need curl or wget to fetch the installer script. Install it if it’s missing:
sudo apt install curl -y
Having a clean environment reduces the risk of conflicting packages and speeds up the installation process.
Proton VPN CLI install is easier when you have the latest package manager. On Debian‑based systems, apt‑full can provide additional utilities. For Fedora, ensure dnf‑plugins-core is installed.
Once your system is prepared, proceed to download the official Proton VPN client script.
2. Downloading the Proton VPN Client
Proton VPN command line setup is supported via a shell script hosted by Proton. To fetch the script, run:
curl -sSL https://protonvpn.com/download/protonvpn-cli.sh -o protonvpn-cli.sh
This script installs the Proton VPN command‑line tool. The Proton VPN CLI install guide on our blog offers a deeper dive into custom options you might want to set during installation.
After downloading, give the script execute permissions:
chmod +x protonvpn-cli.sh
Now you’re ready to run the installer. Proton VPN CLI install will automatically detect your distribution and install the appropriate packages.
3. Installing Proton VPN
Execute the installer with:
sudo ./protonvpn-cli.sh
The script will prompt you to confirm the installation. Press Enter to continue. During installation, it may ask you to install the Proton VPN repository. Accepting the default options will add the repository to your system and install the CLI client.
Once installation completes, you’ll see a success message. You can confirm the installation by running:
protonvpn --version
This command should display the installed version number and the Proton VPN CLI install date. It confirms that the tool is ready for use.
4. Logging In
To use Proton VPN, you must log in with your Proton account credentials. Run:
protonvpn login
Enter your email and password when prompted. After successful login, you’ll receive a message confirming your authenticated session.
If you prefer using a recovery key or two‑factor authentication, the Proton VPN CLI supports these methods. Refer to the Proton documentation for detailed instructions.
5. Configuring the CLI
The Proton VPN command line setup includes a configuration file located at ~/.config/protonvpn/config.ini. You can edit this file to set defaults for server selection, protocol, and other options. For example:
[settings]
protocol = tcp
server = us
When you start a connection without specifying a server, the CLI will use these defaults. To explore all available options, type:
protonvpn --help
This displays a comprehensive list of commands and flags.
6. Connecting to a Server
Once you’re logged in, connect to a server by specifying a country or region:
protonvpn c us
The CLI will automatically select the fastest available server in the United States. If you want a specific server, you can list all servers with:
protonvpn s
After choosing a server, the CLI will establish an encrypted tunnel. You’ll see the connection status and latency in the terminal.
7. Verifying Your Connection
To confirm that your traffic is routed through Proton VPN, check your IP address:
curl ifconfig.me
The IP returned should differ from your original public IP. Additionally, run:
protonvpn info
This displays connection details such as server name, protocol, and encryption method.
8. Disconnecting
When you’re finished, disconnect by running:
protonvpn d
The CLI will tear down the VPN tunnel and revert your network settings to normal.
9. Troubleshooting Common Issues
Some users may encounter a “tunnel setup failed” error. If that happens, consult the Proton VPN tunnel setup guide: Proton VPN Linux troubleshooting. This resource covers common firewall conflicts, DNS leaks, and other configuration problems that can prevent a successful connection.
Another frequent problem is the “connection timed out” error. For a detailed fix, see: Proton VPN Linux install guide. This page walks through resolving network timeouts and ensures that your system can reach Proton’s servers.
If you run into a “no openvpn binary found” message, ensure OpenVPN is installed. On Ubuntu, use:
sudo apt install openvpn
After installing, re‑run the connection command. The Proton VPN CLI install script should now be able to locate the OpenVPN binary.
10. Updating the Client
Keep your Proton VPN CLI up to date with:
sudo ./protonvpn-cli.sh --update
This checks for the latest version and installs it if available. Staying current ensures you receive security patches and new feature releases.
Tips
Security Tips
Proton VPN uses strong encryption by default. However, you can further enhance security by selecting the ikev2 protocol when supported. For example:
protonvpn c us -p ikev2
Proton VPN command line setup allows you to create a custom profile that enforces strict encryption. Combine this with Proton’s kill‑switch feature to block traffic if the VPN disconnects unexpectedly.
Proton’s DNS leak protection is a default feature, but you can verify it by visiting Cloudflare’s DNS leak test to confirm your DNS requests remain private.
Remember to keep your credentials secure. Use Proton’s recovery key and enable two‑factor authentication for added protection. The EFF’s privacy guidelines are an excellent resource for understanding how to manage credentials responsibly.
Performance Tips
When you’re on a congested network, switching to TCP may yield more stable connections. Use:
protonvpn c us -p tcp
If you notice high latency, try connecting to a nearby server by specifying the city. Proton VPN CLI install supports city codes such as nyc for New York City. Example:
protonvpn c nyc
Additionally, you can enable Proton’s netshield to block ads and trackers automatically. This can improve bandwidth usage and reduce exposure to malicious content.
Alternative Methods
Using Proton VPN on Other Operating Systems
While this guide focuses on Linux, Proton VPN also offers clients for macOS, Windows, Android, and iOS. The setup process on macOS mirrors the Linux CLI, with the addition of a configuration file located in ~/Library/Application Support/ProtonVPN.
For Windows, use the graphical installer and enable the run‑as‑admin option to avoid permission issues. On Android, the official app provides a “VPN” toggle that can be set as a system service.
Using Third‑Party Tools
Some users prefer to manage Proton VPN connections via third‑party tools such as networkmanager‑vpn or openvpn‑configurator. These tools can simplify configuration but may not expose all Proton VPN features.
For advanced users, you can script Proton VPN connections using systemd units. Create a protonvpn.service file to start the VPN at boot. This is useful for servers that require a persistent VPN connection.
Another alternative is to use WireGuard if Proton VPN supports it. WireGuard offers lower overhead and faster handshakes, but configuration via the CLI remains similar to OpenVPN.
Community Scripts
The open‑source community offers many scripts for automating Proton VPN connections. Check the Proton Linux install page for a curated list of scripts that can speed up the setup process.
Some scripts also integrate with cron to automatically reconnect if the VPN drops. This is helpful for remote servers that rely on consistent connectivity.
Using Proton VPN with Docker
For containerized environments, you can run Proton VPN inside a Docker container. Create a Dockerfile that installs openvpn and the Proton CLI, then expose the VPN tunnel to other containers via a custom network. This approach isolates VPN traffic from your main application stack.
