 # GlobalProtect-openconnect
-A GlobalProtect VPN client (GUI) for Linux based on Openconnect and built with Qt5, supports SAML auth mode, inspired by [gp-saml-gui](https://github.com/dlenski/gp-saml-gui).
+
+A GUI for GlobalProtect VPN, based on OpenConnect, supports the SSO authentication method. Inspired by [gp-saml-gui](https://github.com/dlenski/gp-saml-gui).
 
 <p align="center">
-  <img src="screenshot.png">
+  <img width="300" src="https://github.com/yuezk/GlobalProtect-openconnect/assets/3297602/9242df9c-217d-42ab-8c21-8f9f69cd4eb5">
 </p>
 
-## Prerequisites
+## Features
 
-- Openconnect v8.x
+- [x] Better Linux support
-- Qt5, qt5-webengine, qt5-websockets
+- [x] Support both CLI and GUI
+- [x] Support both SSO and non-SSO authentication
+- [x] Support authentication using default browser
+- [x] Support multiple portals
+- [x] Support gateway selection
+- [x] Support auto-connect on startup
+- [x] Support system tray icon
 
-### Ubuntu
+## Usage
-1. Install openconnect v8.x
-    Update openconnect to 8.x, for ubuntu 18.04 you might need to [build the latest openconnect from source code](https://gist.github.com/yuezk/ab9a4b87a9fa0182bdb2df41fab5f613).
-2. Install the Qt dependencies
-    ```sh
-    sudo apt install qt5-default libqt5websockets5-dev qtwebengine5-dev
-    ```
-## Install
 
-### Install from AUR (Arch/Manjaro)
+### CLI
 
-Install [globalprotect-openconnect](https://aur.archlinux.org/packages/globalprotect-openconnect/).
+The CLI version is always free and open source in this repo. It has almost the same features as the GUI version.
 
-### Build from source code
-
-```sh
-git clone https://github.com/yuezk/GlobalProtect-openconnect.git
-cd GlobalProtect-openconnect
-git submodule update --init
-qmake CONFIG+=release
-make
-sudo make install
 ```
-Open `GlobalProtect VPN` in the application dashboard.
+Usage: gpclient [OPTIONS] <COMMAND>
+
+Commands:
+  connect     Connect to a portal server
+  disconnect  Disconnect from the server
+  launch-gui  Launch the GUI
+  help        Print this message or the help of the given subcommand(s)
+
+Options:
+      --fix-openssl        Get around the OpenSSL `unsafe legacy renegotiation` error
+      --ignore-tls-errors  Ignore the TLS errors
+  -h, --help               Print help
+  -V, --version            Print version
+
+See 'gpclient help <command>' for more information on a specific command.
+```
+
+### GUI
+
+The GUI version is also available after you installed it. You can launch it from the application menu or run `gpclient launch-gui` in the terminal.
+
+> [!Note]
+>
+> The GUI version is partially open source. Its background service is open sourced in this repo as [gpservice](./apps/gpservice/). The GUI part is a wrapper of the background service, which is not open sourced.
+
+## Installation
+
+> [!Note]
+>
+> This instruction is for the 2.x version. The 1.x version is still available on the [1.x](https://github.com/yuezk/GlobalProtect-openconnect/tree/1.x) branch, you can build it from the source code by following the instructions in the `README.md` file.
+
+> [!Warning]
+>
+> The client requires `openconnect >= 8.20`, please make sure you have it installed, you can check it with `openconnect --version`.
+> Installing the client from PPA will automatically install the required version of `openconnect`.
+
+### Debian/Ubuntu based distributions
+
+#### Install from PPA
+
+```
+sudo add-apt-repository ppa:yuezk/globalprotect-openconnect
+sudo apt-get update
+sudo apt-get install globalprotect-openconnect
+```
+
+> [!Note]
+>
+> For Linux Mint, you might need to import the GPG key with: `sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7937C393082992E5D6E4A60453FC26B43838D761` if you encountered an error `gpg: keyserver receive failed: General error`.
+
+#### Install from deb package
+
+Download the latest deb package from [releases](https://github.com/yuezk/GlobalProtect-openconnect/releases) page. Then install it with `dpkg`:
+
+```bash
+sudo dpkg -i globalprotect-openconnect_*.deb
+```
+
+### Arch Linux / Manjaro
+
+#### Install from AUR
+
+Install from AUR: [globalprotect-openconnect-git](https://aur.archlinux.org/packages/globalprotect-openconnect-git/)
+
+```
+yay -S globalprotect-openconnect-git
+```
+
+#### Install from package
+
+Download the latest package from [releases](https://github.com/yuezk/GlobalProtect-openconnect/releases) page. Then install it with `pacman`:
+
+```bash
+sudo pacman -U globalprotect-openconnect-*.pkg.tar.zst
+```
+
+### Fedora/OpenSUSE/CentOS/RHEL
+
+#### Install from COPR
+
+The package is available on [COPR](https://copr.fedorainfracloud.org/coprs/yuezk/globalprotect-openconnect/) for various RPM-based distributions. You can install it with the following commands:
+
+```
+sudo dnf copr enable yuezk/globalprotect-openconnect
+sudo dnf install globalprotect-openconnect
+```
+
+#### Install from OBS
+
+The package is also available on [OBS](https://build.opensuse.org/package/show/home:yuezk/globalprotect-openconnect) for various RPM-based distributions. You can follow the instructions [on this page](https://software.opensuse.org//download.html?project=home%3Ayuezk&package=globalprotect-openconnect) to install it.
+
+#### Install from RPM package
+
+Download the latest RPM package from [releases](https://github.com/yuezk/GlobalProtect-openconnect/releases) page.
+
+### Other distributions
+
+The project depends on `openconnect >= 8.20`, `webkit2gtk`, `libsecret`, `libayatana-appindicator` or `libappindicator-gtk3`. You can install them first and then download the latest binary release (i.e., `*.bin.tar.gz`) from [releases](https://github.com/yuezk/GlobalProtect-openconnect/releases) page.
