Linux Systems Programming: Network Programming#

This course covers the socket interface and some of the protocols that are supported by it, together with the programming paradigms that are common with networking.

Course Outline#

  • Network programming basics. The socket interface is defined in abstract terms, not mentioning any of TCP/IP, or Bluetooth or … .

    • Systemcalls: socket(), connect(), bind(), listen(), accept()

    • Stream communication: connection establishment and communication

    • Datagrams: connectionless communication

    • Error scenarios

    • Adress families

  • TCP/IP. Network programming on The Internet

    • TCP and UDP

    • Address conversion routines

    • DNS-Lookup

    • IPv4 and IPv6

  • UNIX Domain Sockets. An interprocess communication mechanism for processes running on the same machine.

  • CAN-Bus. CAN (Controller Area Network) fits itself into the Linux network stack.

  • Event loops (select/poll/epoll).

    • Event driven programming

    • Nonblocking connection establishment

    • Nonblocking IO

    • Other applications of events: timers (via timer file descriptors), events (via event file descriptors)

Prerequisites#

A solid understanding of the C programming language is helpful. Fun with low-level hacking is required.
