Usage

Command-Line Interface

The CLI is free and open source. Use it to authenticate, connect to portals or gateways, and generate HIP reports from the terminal.

Basic Commands

Usage: gpclient [OPTIONS] <COMMAND>

Commands:
  connect     Connect to a portal server
  disconnect  Disconnect from the server
  launch-gui  Launch the GUI
  hip         Generate HIP report
  help        Print this message or the help of the given subcommand(s)

Options:
      --fix-openssl              Uses extended compatibility mode for OpenSSL operations to support a broader range of systems and formats.
      --ignore-tls-errors        Ignore the TLS errors
      --lock-file <LOCK_FILE>    Path to the gpclient PID lock file
      --log-format <LOG_FORMAT>  Log output format. JSON is intended for non-interactive consumers; interactive prompts remain text. [default: text] [possible values: text, json]
  -v, --verbose...               Enable verbose output, -v for debug, -vv for trace
  -q, --quiet...                 Decrease logging verbosity, -q for warnings, -qq for errors
  -h, --help                     Print help (see more with '--help')
  -V, --version                  Print version

The --fix-openssl option is available on Linux, FreeBSD, and OpenBSD. macOS uses native TLS and GnuTLS and does not accept this option.

Tip: Use gpclient help <command> for detailed information on a specific command.

HIP reports

HIP is disabled in the CLI unless enabled explicitly. Use --hip to generate reports inside gpclient, including later reports requested by the gateway:

sudo gpclient connect <portal> --hip

Use --hip=/absolute/path/to/script for a custom executable. It runs as the gpclient process user unless --hip-user specifies another user. No installed HIP script is discovered automatically. --hip-user applies only to custom executables.

gpclient hip generates a report on demand for inspection; see gpclient hip --help for report inputs. The GUI's HIP tab supports generated reports, edited XML, and HIP Off on all desktop platforms. Linux, FreeBSD, and OpenBSD also support desktop-user scripts and explicitly approved root scripts.

External Browser Authentication

Use gpclient directly for browser-based authentication. It opens the browser as your normal desktop user while keeping VPN tunnel setup privileged:

sudo gpclient connect <portal> --browser

For standalone CLI installations, use --browser manual (--browser remote before v3.0.6): open the printed URL and paste the resulting globalprotectcallback:… data into the terminal.

To reuse a saved portal cookie for later connections, add --cookie-cache:

sudo gpclient connect <portal> --browser --cookie-cache

Add --gateway <gateway> to select a particular gateway. Cookie caching is handled by gpclient. Its default cache file is $HOME/.config/gpclient/cookie.json, which normally belongs to root when running with sudo. To choose a predictable location, specify the path explicitly:

sudo gpclient connect <portal> --browser --cookie-cache=/absolute/path/to/cookie.json

Browser Options:

• Use --browser to automatically select an available browser
• Use --browser <browser> to specify a browser (e.g., firefox, chrome)
• Use --browser manual for standalone CLI installations or headless servers

Graphical User Interface

GP Connect provides a desktop interface for managing VPN connections. On macOS, open GP Connect from Applications. On Linux, FreeBSD, and OpenBSD, launch it from your application menu or via the terminal:

gpclient launch-gui

[!Note]

The GUI version is partially open source. The background service (gpservice) is open source, while the GUI wrapper is proprietary.

Installation

[!Note]

For older Linux distributions, use v2.3.13 instead of the latest release. It provides release assets for common distro families, including Debian/Ubuntu (.deb), Arch Linux / Manjaro (.pkg.tar.zst), RPM-based distros such as Fedora / RHEL / Rocky / AlmaLinux / CentOS (.rpm), and generic Linux tarballs (.bin.tar.xz).

macOS

GP Connect requires Apple silicon and macOS 13 or later. The macOS app includes both the desktop application and the free gpclient CLI. The CLI does not require a GUI license.

Option 1: Install with Homebrew

brew install --cask yuezk/gp-connect/gp-connect

Open GP Connect from Applications, or connect from the terminal:

sudo gpclient connect <portal> --browser

Option 2: Install from DMG

Download the GP Connect .dmg from the releases page, open it, and drag GP Connect into Applications.

Debian / Ubuntu

Option 1: Install from PPA (Recommended)

sudo add-apt-repository ppa:yuezk/globalprotect-openconnect
sudo apt-get update
sudo apt-get install globalprotect-openconnect

[!Note]

For Linux Mint users: If you encounter a GPG key error, import the key manually:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7937C393082992E5D6E4A60453FC26B43838D761

Option 2: Install from DEB Package

Download the latest .deb package from the releases page, then install:

sudo apt install --fix-broken ./globalprotect-openconnect_*.deb

Arch Linux / Manjaro

Option 1: Install from AUR

Package: globalprotect-openconnect-git

You can install it using an AUR helper like yay:

yay -S globalprotect-openconnect-git

Option 2: Install from the Official Extra Repository

The package is also available in the official Arch Linux Extra repository.

Package: globalprotect-openconnect

[!Note]

Since the official package does not include the system tray support dependency, you need to install libappindicator manually:

sudo pacman -S libappindicator globalprotect-openconnect

Option 3: Install from Package

Download the latest package from the releases page, then install:

sudo pacman -U globalprotect-openconnect-*.pkg.tar.zst

Fedora 38+ / Rawhide

Install from COPR

The package is available on COPR for RPM-based distributions:

sudo dnf copr enable yuezk/globalprotect-openconnect
sudo dnf install globalprotect-openconnect

openSUSE Leap 15.6+ / Tumbleweed

Install from OBS (openSUSE Build Service)

Packages are available on the openSUSE Build Service. Follow the installation instructions for your distribution.

Other RPM-based Distributions

Install from RPM Package

Download the latest RPM package from the releases page:

sudo rpm -i globalprotect-openconnect-*.rpm

Alpine Linux

Download the latest .apk package from the releases page, then install:

sudo apk add --allow-untrusted globalprotect-openconnect-*.apk

The package uses Alpine's native musl build. Make sure the community repository is enabled so GUI dependencies such as webkit2gtk-4.1, libsecret, and libayatana-appindicator can be resolved. GUI-launched connections use polkit, and VPN tunnel creation requires /dev/net/tun.

FreeBSD

Download the latest FreeBSD package from the releases page, then install:

sudo pkg install ./globalprotect-openconnect-*-freebsd-*.pkg

To build from source, see Building from Source on FreeBSD and OpenBSD.

OpenBSD

Download the latest OpenBSD package from the releases page, then install:

doas pkg_add -D unsigned ./globalprotect-openconnect-*-openbsd-*.tgz

To build from source, see Building from Source on FreeBSD and OpenBSD.

Gentoo

Available via the guru and lamdness overlays:

sudo eselect repository enable guru
sudo emerge --sync guru
sudo emerge --ask --verbose net-vpn/GlobalProtect-openconnect

NixOS

This repository includes a flake for NixOS integration.

Installation Steps

Add the flake input and NixOS module to your flake.nix:

The module builds the package with your NixOS configuration's pkgs, so the GlobalProtect GUI and the system use the same Nixpkgs dependency versions. It also enables Polkit and its setuid pkexec wrapper for privileged operations.

{
  inputs = {
    # ... other inputs
    globalprotect-openconnect.url = "github:yuezk/GlobalProtect-openconnect";
  };

  outputs = { self, nixpkgs, globalprotect-openconnect, ... }:
    let
      system = "x86_64-linux"; # or "aarch64-linux" for ARM64
      hostname = "<your-host>";
    in {
      nixosConfigurations.${hostname} = nixpkgs.lib.nixosSystem {
        inherit system;

        modules = [
          ./configuration.nix
          globalprotect-openconnect.nixosModules.default
          {
            programs.globalprotect-openconnect.enable = true;

            environment.systemPackages = [
              nixpkgs.legacyPackages.${system}.gnomeExtensions.appindicator
            ];
          }
        ];
      };
    };
}

Apply:

sudo nixos-rebuild switch
loginctl terminate-user "$USER"

After logging back in to GNOME, enable AppIndicator support if needed:

gnome-extensions enable appindicatorsupport@rgcjonas.gmail.com

NixOS does not run an imperative package-uninstall hook when a package is removed from the system configuration. Remove an installed replacement VPN script from the app settings before removing the package.

The prebuilt package and NixOS module use the published release pinned in flake.nix. Both prebuilt and fromSource run natively on the host with packaged dependencies and installer paths. The fromSource package builds the current flake checkout, including its Git submodules:

git submodule update --init --recursive
nix build "git+file://$PWD?submodules=1#fromSource"

Local source builds require initialized Git submodules and a flake URL with submodules=1, as shown above. For a remote source flake, use a Git URL with submodules enabled, such as git+https://github.com/yuezk/GlobalProtect-openconnect?submodules=1#fromSource. The prebuilt package and NixOS module do not require Git submodules. Build output (target, .build, and node_modules) is excluded from the source input. Updating release asset hashes changes the prebuilt package, independently of source builds.

Official Docker Image

The official Docker image provides the CLI tools on Alpine Linux:

docker pull yuezk/globalprotect-openconnect:<version>

Release images are tagged as vX.Y.Z, X.Y.Z, and latest.

Run it with access to the TUN device:

docker run --rm -it --cap-add=NET_ADMIN --device=/dev/net/tun \
  yuezk/globalprotect-openconnect:<version> \
  connect <portal>

For browser authentication in a headless environment, use manual browser authentication:

docker run --rm -it --cap-add=NET_ADMIN --device=/dev/net/tun \
  yuezk/globalprotect-openconnect:<version> \
  connect <portal> --browser manual

On a host with multiple network interfaces, use --browser-listen to select the IP address reachable from the browser machine:

gpclient connect <portal> --browser manual --browser-listen 192.168.107.15

On a Linux host, add host networking if the VPN routes should affect the host network namespace:

docker run --rm -it --network host --cap-add=NET_ADMIN --device=/dev/net/tun \
  yuezk/globalprotect-openconnect:<version> \
  connect <portal> --browser manual

Without --network host, the VPN connection stays inside the container's network namespace. Docker Desktop on macOS and Windows does not make the host use the VPN through --network host; run gpclient on the host or use a container gateway setup for host traffic.

The image includes gpclient and gpauth only. It does not include embedded webview authentication, gpgui-helper, or gpgui.

   sudo make install
   

Building from Source

The instructions below build the open-source components on Linux. For FreeBSD and OpenBSD, see Building from Source on FreeBSD and OpenBSD.

Method 1: Using DevContainer

This project includes a DevContainer configuration for Linux development. The repository's rust-toolchain.toml selects the Rust toolchain; rustup may need to download it on the first build.

Prerequisites

• Docker
• Visual Studio Code (optional, for IDE support)
• Dev Containers extension (if using VS Code)

Build Steps

1. Clone the repository:

   git clone https://github.com/yuezk/GlobalProtect-openconnect.git
   cd GlobalProtect-openconnect
   git submodule update --init --recursive
   

2. Build the DevContainer image:

   docker build -t gpoc-devcontainer .devcontainer/
   

3. Build the project:

   To build the open-source components, including the GUI helper, run:

   docker run --privileged --cap-add=NET_ADMIN --device=/dev/net/tun \
     --tty -v "$(pwd)":/workspace -w /workspace gpoc-devcontainer \
     bash -c "export PATH=/usr/local/cargo/bin:\$PATH && make build"
   

   To build without the GUI helper run the same command as above, but with BUILD_GUI_HELPER=0 passed as an argument to make.

4. Locate build artifacts:

   The compiled binaries will be available in target/release/:

   • gpclient – CLI client
   • gpservice – Background service
   • gpauth – Authentication helper
   • gpgui-helper – GUI helper
   • gp-hip-script-installer – Privileged HIP script installer
   • gp-vpnc-script-installer – Privileged VPN script installer

   The proprietary GP Connect desktop application is distributed separately. Use INCLUDE_GUI=1 with make build to download its matching published Linux build for installation.

Alternative: Using VS Code

1. Open the project in VS Code
2. When prompted, click "Reopen in Container" (or run Dev Containers: Reopen in Container)
3. Once the container is ready, open a terminal and run:

   make build
   

Method 2: Local Development Build

Prerequisites

• Rust 1.91 or later
• Tauri dependencies
• OpenConnect source-build dependencies: autoconf, automake, autopoint/gettext, libtool, patch, pkg-config, libxml2, zlib, lz4, gnutls, p11-kit, nettle, and gmp development packages
• pkexec and gnome-keyring (or pam_kwallet on KDE)
• Node.js and pnpm if rebuilding the GUI helper frontend

Build Steps

1. Download source code:

   Download globalprotect-openconnect-${version}.tar.gz from the releases page.

2. Extract and build:

   tar -xzf globalprotect-openconnect-${version}.tar.gz
   cd globalprotect-openconnect-${version}
   make build
   

3. Install:

   sudo make install
   

   To stage the files for packaging instead of installing them into the system, use make install DESTDIR=/absolute/path/to/staging.

Testing Your Build

Verify the CLI client is working correctly:

./target/release/gpclient --help

Build Options

• BUILD_GUI_HELPER=0 – Skip building and installing the GUI helper
• BUILD_WEBVIEW_AUTH=0 – Build gpauth without embedded browser authentication; use an external browser or manual authentication
• INCLUDE_GUI=1 – Download the matching published Linux desktop application for installation
• OFFLINE=1 – Build in offline mode using vendored dependencies

Frequently Asked Questions

When reporting a problem, follow the diagnostics collection instructions. A standalone script is available for versions without the diagnostics command; you do not need to upgrade first.

Q: How do I resolve the "Secure Storage not ready" error?

Unlock your desktop keyring and ensure the application can access it. On Linux and BSD, check that a keyring service such as GNOME Keyring is installed and running in your desktop session. On macOS, check Keychain access.

Linux and BSD can use file storage when secure storage is unavailable during initial setup. An existing configuration that uses the keyring still needs access to that keyring.

See related issues: #321, #316

Q: How do I fix the "cannot open display" error when using CLI?

Run the client from a terminal in your normal desktop session and use an external browser:

sudo gpclient connect <portal> --browser

See related issue: #316

On a headless server, use --browser manual and complete authentication from another machine.

NetworkManager Integration

• WMP/GlobalProtect-SAML-NetworkManager – NetworkManager VPN plugin with SAML/SSO support for GNOME and KDE Plasma
• jdpipe/networkmanager-gpclient – NetworkManager VPN plugin that uses gpclient
