This book is an invaluable resource for aspiring network administrators aiming to deepen their understanding of networking concepts while strengthening their C++ programming skills. Across eleven chapters, this book bridges the gap between network administration and programming, providing readers with a holistic approach to mastering network operations. Readers begin with a deep dive into network fundamentals such as TCP/IP models, sockets, and protocols. They then progress to practical programming, employing C++ to establish TCP/UDP client-server connections, handle network errors, and deal with application layer protocols such as HTTP/HTTPS, FTP, SMTP, IMAP, and DNS. The book then guides readers through Virtual Private Networks (VPNs), detailing their importance, functioning, and distinct types of VPNs. It explores wireless networking and asynchronous programming, providing clear illustrations of WiFi, Bluetooth, and Zigbee setup using C++. It covers critical wireless standards and security protocols. For a comprehensive understanding, the book illustrates network configuration management using C++ to automate crucial network operations tasks, thus highlighting the power of programming in network management. Advanced topics include network testing and simulations, which provide insights into performance enhancement and network robustness. A detailed exploration of network monitoring enhances the reader's skillset, teaching ways to conduct fault, performance, security, and account monitoring. In the end, the book rounds up with network troubleshooting, elucidating several essential network troubleshooting tools and methodologies. Key Learnings Understand TCP/IP model and protocols with hands-on C++ programming. Master TCP/UDP client-server connections and error handling. Grasp application layer protocols like HTTP/HTTPS, FTP, SMTP, IMAP, and DNS. Discover the importance and use of VPNs and how to set them up.
