Hands-On Network Programming with C

By: Lewis Van Winkle

Overview of this book

Network programming enables processes to communicate with each other over a computer network, but it is a complex task that requires programming with multiple libraries and protocols. With its support for third-party libraries and structured documentation, C is an ideal language to write network programs. Complete with step-by-step explanations of essential concepts and practical examples, this C network programming book begins with the fundamentals of Internet Protocol, TCP, and UDP. You’ll explore client-server and peer-to-peer models for information sharing and connectivity with remote computers. The book will also cover HTTP and HTTPS for communicating between your browser and website, and delve into hostname resolution with DNS, which is crucial to the functioning of the modern web. As you advance, you’ll gain insights into asynchronous socket programming and streams, and explore debugging and error handling. Finally, you’ll study network monitoring and implement security best practices. By the end of this book, you’ll have experience of working with client-server applications and be able to implement new network programs in C. The code in this book is compatible with the older C99 version as well as the latest C18 and C++17 standards. You’ll work with robust, reliable, and secure code that is portable across operating systems, including Winsock sockets for Windows and POSIX sockets for Linux and macOS.

Appendix 3. Setting Up Your C Compiler on Linux

Linux is an excellent choice for C programming. It has arguably the easiest setup and the best support for C programming out of the three operating systems covered in this book.

Using Linux also allows you to take the ethical high road and feel good about supporting free software.

One issue with describing the setup for Linux is that there are many Linux distributions with different software. In this appendix, we will provide the commands needed to set up on systems using the apt package manager, such as Debian Linux and Ubuntu Linux. If you are using a different Linux distribution, you will need to find the commands relevant to your system. Refer to your distribution's documentation for help.

Before diving right in, take a moment to make sure your package list is up to date. This is done with the following command:

sudo apt-get update

With apt ready to go, setup is easy. Let's get started.
