Hands-on: OpenVPN: Installing and configuring an OpenVPN server and gateway, and setting up OpenVPN clients on Linux and Android (Private and Secure Computing)

This book guides you through the full installation and configuration of an OpenVPN server and gateway on Linux, followed by the set-up of clients on Linux and Android. Working your way through the book, each section provides you with a fully functional set-up. That makes this book ideal for people with general Linux and networking skills, wanting to build an infrastructure facilitating private and secure computing for themselves or their users.

Each section provides a quick introduction and overview of the software, followed by a task-driven manual to build a complete set-up. In addition to the instructions, screengrabs and configuration listings, we provide further options and variations, examples, tips and tricks, warnings, and security/privacy implications. Although familiarity with Linux and networking is required, this book contains everything that is needed to build a complete and operational set-up: configuring the private IP network, adding the domain name to BIND named, generating the PKI credentials, opening up the firewall, enabling IP forwarding, routing and masquerading, setting up DNS resolving, enabling the Linux daemons, using the Android Keychain credentials store, and configuring OpenVPN Connect.

本書將引導您完整安裝和配置Linux上的OpenVPN服務器和網關，然後在Linux和Android上設置客戶端。通過閱讀本書，每個部分都提供了一個完全功能的設置。這使得本書非常適合具有一般Linux和網絡技能的人，他們希望為自己或用戶建立一個促進私密和安全計算的基礎設施。

每個部分都提供了軟件的快速介紹和概述，然後是一個以任務為導向的手冊，用於構建完整的設置。除了提供指令、屏幕截圖和配置清單外，我們還提供了進一步的選項和變化、示例、技巧和提示、警告以及安全/隱私影響。雖然需要熟悉Linux和網絡，但本書包含了構建完整且可運行的設置所需的一切：配置私有IP網絡，將域名添加到BIND named，生成PKI憑證，打開防火牆，啟用IP轉發、路由和偽裝，設置DNS解析，啟用Linux守護進程，使用Android Keychain憑證存儲庫，以及配置OpenVPN Connect。
