Product Description
This book is a comprehensive guide to using OpenVPN for building both secure VPNs. The book is written in a very friendly style that makes this complex topic easy and a joy to read. It first covers basic VPN concepts, then moves to introduce basic OpenVPN configurations, before covering advanced uses of OpenVPN. It's suitable for both experienced and new OpenVPN users.

OpenVPN is a powerful, open source SSL VPN application. It can secure site-to-site connections, WiFi and enterprise-scale remote connections. While being a full-featured VPN solution, OpenVPN is easy to use and does not suffer from the complexity that characterizes other IPSec VPN implementations. It uses the secure and stable TLS/SSL mechanisms for authentication and encryption.

This book is an easy introduction to this popular VPN application. After introducing the basics of security and VPN, the book moves on to cover using OpenVPN, from installing it on various platforms, through configuring basic tunnels, to more advanced features, such as using the application with firewalls, routers, proxy servers, and OpenVPN scripting. While providing the necessary theoretical background, the book takes a practical approach, presenting plenty of examples.

What you will learn from this book

Chapter 1 looks at what VPNs are, how they evolved during the last decade, why it is necessary to modern Benterprises, how typical VPNs work. The chapter also covers some essential networking concepts.

Chapter 2 explains VPN security issues, including symmetric and asymmetric encryption, the SSL/TLS library, and SSL certificates.

Chapter 3 introduces OpenVPN. In this chapter, we learn about the history of OpenVPN, how OpenVPN works, and how OpenVPN compares to IPSec VPN applications.

Chapter 4 covers installing OpenVPN on both Windows, the Mac, Linux, and FreeBSD. It covers the installation on Linux from the source code and RPM packages. Installation on Suse and Debian is covered in detail.

Chapter 5. Here an encryption key for OpenVPN is created and it is then used to setup up our first OpenVPN Tunnel between two windows systems in the same network. The key is then copied on a Linux system and this system is connected through a tunnel to the first windows machine.

Chapter 6 shows how to create x509 server and client certificates for use with OpenVPN. easy-rsa which comes with OpenVPN and is available for both Windows and Linux is used.

Chapter 7 reviews the syntax of the command line tool openvpn, which enables building tunnels quickly. The configuration options of openvpn are covered in detail with examples.

Chapter 8 shows how to make the example tunnels created earlier safer and persistent by choosing a reliable combination of configuration file parameters. It then covers how to configure firewalls on Linux and Windows to work with OpenVPN.

Chapter 9 focuses on using xca, the advanced Windows tool with which x509 certificates can be easily managed. Its Linux equivalent, Tinyca2, which can even manage multiple certificate authorities, is also covered.

Chapter 10 covers advanced OpenVPN configurations, including Tunneling through a proxy server, pushing routing commands to clients, pushing and setting the default route through a tunnel, Distributed compilation through VPN tunnels with distcc, and OpenVPN scripting.

Chapter 11 shows how to debug and monitor VPN tunnels. It covers standard networking tools that can be used for scanning and testing the connectivity of a VPN server.

Network Programming :

This document has been written as a tutorial, not a reference. It is probably at its best when
read by individuals who are just starting out with socket programming and are looking for a
foothold. It is certainly not the complete guide to sockets programming, by any means.
Hopefully, though, it'll be just enough for those man pages to start making sense...

TCP/IP spcket in C :

We wrote this book to improve the support for socket-based programming exercises in
our own networking courses. Although some networking texts deal with network programming,
we know of none that cover TCP/IP sockets. Excellent reference books on TCP/IP socket
programming exist, but they are too large and comprehensive to be considered as a supplement
to a networking text. UNIX "man pages" are okay for reference but do not make a very
good tutorial. Our goal, therefore, was to provide a gentle introduction, and a handy reference,
that would allow students to dive right in without too much handholding.
