Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it was impossible to predict how quickly and thoroughly WiFi would penetrate the marketplace. Today, with WiFi-enabled computers almost as common as Ethernet, it makes even more sense to take the next step and network your community using nothing but freely available radio spectrum. This book has showed many people how to make their network available, even from the park bench, how to extend high-speed Internet access into the many areas not served by DSL and cable providers, and how to build working communities and a shared though intangible network. All that's required to create an access point for high-speed Internet connection is a gateway or base station. Once that is set up, any computer with a wireless card can log onto the network and share its resources. Rob Flickenger built such a network in northern California, and continues to participate in network-building efforts. His nuts-and-bolts guide covers: Selecting the appropriate equipment Finding antenna sites, and building and installing antennas Protecting your network from inappropriate access New network monitoring tools and techniques (new) Regulations affecting wireless deployment (new) IP network administration, including DNS and IP Tunneling (new) His expertise, as well as his sense of humor and enthusiasm for the topic, makes Building Wireless Community Networks a very useful and readable book for anyone interested in wireless connectivity.

Learn how to build your own VPN server in the cloud or on a Raspberry Pi This book is a step-by-step guide to building your own IPsec VPN, OpenVPN and WireGuard server. Based on 10 years of open source work with millions of users, this book will help you build your own VPN in just a few minutes, even if you haven't set up a server or used a VPN before. By reading this book you will learn how to: ✔ Create a cloud server on DigitalOcean, Vultr, Linode and OVH ✔ Connect using SSH and set up WireGuard, OpenVPN and IPsec VPN with IKEv2 ✔ Configure VPN clients on Windows, macOS, Android and iOS ✔ Manage WireGuard, OpenVPN and IKEv2 VPN clients In the digital age, cyber security and privacy are more important than ever. Using a virtual private network (VPN) can help improve your cybersecurity and privacy by encrypting your network traffic, so that your data is protected as it travels via the Internet. This is especially useful when using unsecured Wi-Fi networks, such as at coffee shops, airports or in hotel rooms. Creating your own VPN server has become easier than ever, thanks to advances in technology such as affordable cloud servers and reduced bandwidth costs. Self-hosted VPNs can be considerably cheaper than commercial ones and offer several advantages. The VPN setup process can be fully automated and as simplified as possible. This book will help you build your own VPN server in the cloud or on a Raspberry Pi in just a few minutes. Get your copy of this book today and start building your own VPN!
