Course overview

The Linux/UNIX network programming course covers network programming using the sockets API on Linux and UNIX systems. The content of the course is based on the network programming chapters of The Linux Programming Interface, but adds a significant amount of supplementary material.

• "Standard" courses are normally three days long, and are delivered either live online, at a public training location, or on-site at customer premises. The content may vary a little, according to specific topic requests and time constraints, but in broad terms will cover the following topics:
  
  
  • Overview of relevant background pieces of the Linux/UNIX API (including signals, process creation, and program execution)
  • Sockets overview
  • Programming with UNIX domain sockets
  • TCP/IP overview; UDP and TCP
  • Programming with Internet domain sockets
  • Advanced sockets API topics
  • TCP in more detail (TCP segments, TCP state machine, 3-way handshake)
  • Socket options
  • Monitoring and troubleshooting: netstat and tcpdump
  • Alternative I/O models (poll(), select(), signal-driven I/O, epoll)
  • Daemons
  
  A more detailed list of topics can be found here.
  
  
• The course includes practical programming sessions.
  
  

Course details

Course outline.

The course employs a lecture+lab format.

Audience and prerequisites

The primary audience for this course is programmers developing network applications for Linux and UNIX systems, or programmers porting such applications from other operating systems (e.g., Windows) to Linux or UNIX. By the completion of the course, participants will have the understanding needed to write advanced network applications on a Linux or UNIX system.

In order to get the most out of the course, participants should have:

• A good reading knowledge of the C programming language.

  The content of the course is applicable in a range of compiled programming languages, such as C, C++, Rust, and D and scripting languages such as Python, and participants are welcome to use their preferred language in the lab sessions.

• A knowledge of basic UNIX/Linux shell commands.

• A basic knowledge of make(1) is helpful, but not essential.

Lab sessions

A significant part of the course is spent on practical exercises. The lab sessions also provide participants with the opportunity to obtain one-to-one assistance from the trainer on the course material and exercises.

Course materials

Course participants receive course books of around 400 pages. The course books include all of the slides and exercises presented in the course. Some notable features of the course books are the following:

• The course books have been developed by the trainer, and they are constantly updated based on ongoing changes in the Linux kernel, the GNU C library, and the POSIX standards as well as practical teaching experience in courses.
• The course books are closely integrated with The Linux Programming Interface (TLPI), via numerous references to precise locations in TLPI with more detail on various topics covered in the course.
• The course books include many example programs and exercises not found in TLPI.

In addition to the course book, participants receive a copy of The Linux Programming Interface, in ebook form.

Sample materials

The following samples give some idea of the course content and style of the course materials:

• Part of the Alternative I/O Models: epoll course module.
• By the end of the course, participants are in a position to write programs that solve some fairly strenuous exercises, such as this client-server exercise from one of the sockets modules.

About the trainer

Michael Kerrisk has a unique set of qualifications and experience that ensure that course participants receive training of a very high standard:

• He has been programming on UNIX systems since 1987 and began teaching UNIX system programming courses in 1989.
• He is the author of The Linux Programming Interface, a 1550-page book widely acclaimed as the definitive work on Linux system programming.
• He is actively involved in Linux development—working with kernel developers on testing, review, and design of new Linux kernel-user-space APIs.
• From 2004 to 2021, he was the maintainer of the Linux man-pages project, which provides the manual pages documenting the Linux kernel-user-space and GNU C library APIs.
