This is a cross-platform GUI client for OpenConnect, written in Rust and designed to work seamlessly on Windows, Linux, and macOS desktop systems. The program utilizes various technologies including MSYS2, Tauri, React, and NextUI. It provides a user-friendly interface for connecting to VPN servers using both password and OIDC authentication methods.

• Cross-platform compatibility (Windows, Linux, macOS)
• Easy-to-use GUI interface
• Support for both password and OIDC authentication
• Built with MSYS2, Tauri, React, and NextUI

• GUI:

  • Supports Windows(x64), Linux(x64), and macOS(aarch64, x64)

  • Download can be found in Releases

• CLI install:

  • Only supports Linux(x64) and macOS(aarch64, x64)

  • Run the following command in your terminal:

    curl -sL https://raw.githubusercontent.com/hlhr202/Openconnect-RS/main/install-cli.sh | bash

• Run the following command in your terminal:

  openconnect --help

  This will print the following help message:

  A CLI client to connect to VPN using OpenConnect
  
  Usage: openconnect <COMMAND>
  
  Commands:
    start         Connect to a VPN server and run in daemon mode [aliases: connect, run]
    status        Get the current VPN connection status [aliases: info, stat]
    stop          Close the current connection and exit the daemon process [aliases: kill, disconnect]
    add           Add new VPN server configuration to local config file [aliases: new, create, insert]
    import        Import VPN server configurations from a base64 encoded string
    export        Export VPN server configurations to a base64 encoded string
    delete        Delete a VPN server configuration from local config file [aliases: rm, remove, del]
    list          List all VPN server configurations in local config file [aliases: ls, l]
    logs          Show logs of the daemon process [aliases: log]
    gen-complete  Generate shell completion script
    help          Print this message or the help of the given subcommand(s)
  
  Options:
    -h, --help     Print help
    -V, --version  Print version
  

• For each subcommand, you can run openconnect <COMMAND> --help to get more information

  For example:

  openconnect start --help

  This will print the following help message:

  Connect to a VPN server and run in daemon mode
  
  Usage: openconnect start [OPTIONS] <NAME>
  
  Arguments:

  Options:
    -c, --config-file <CONFIG_FILE>  The path to the local config file
    -h, --help                       Print help
  

• ZSH (Oh My Zsh!)

  mkdir -p ~/.oh-my-zsh/custom/plugins/openconnect
  openconnect gen-complete zsh > ~/.oh-my-zsh/custom/plugins/openconnect/openconnect.plugin.zsh

  Then add openconnect to the plugins array in your ~/.zshrc file:

• Bash

  mkdir -p ~/.bash_completion
  openconnect gen-complete bash > ~/.bash_completion/openconnect
  echo "source ~/.bash_completion/openconnect" >> ~/.bashrc

• Read the System Requirements for environment setup
• Modify it to fit your environment (For automatic setup, its WIP)
• For windows, since openconnect provides GNU automake, we currently only support MSYS2-MINGW64 and x86_64-pc-windows-gnu toolchain
  • Install MSYS2
  • Install x86_64-pc-windows-gnu toolchain with command rustup default stable-x86_64-pc-windows-gnu
  • Run cargo under MINGW64 shell
