Book Description
The world of IT is always evolving, but in every area there are stable, core concepts that anyone just setting out needed to know last year, needs to know this year, and will still need to know next year. The purpose of the Foundations series is to identify these concepts and present them in a way that gives you the strongest possible starting point, no matter what your endeavor. TCP/IP Foundations provides essential knowledge about the two protocols that form the basis for the Internet, as well as many other networks. What you learn here will benefit you in the short term, as you acquire and practice your skills, and in the long term, as you use them. Topics covered include: The origins of TCP/IP and the Internet The layers comprising the OSI and DoD models TCP/IP addressing Subnet masks Creating custom subnet masks Supernetting and Classless Inter-Domain Routing (CIDR) Name resolution The Domain Name System (DNS) and Dynamic DNS Windows Internet Naming Services (WINS) The Dynamic Host Configuration Protocol (DHCP) What to expect with IPv6

TCP/IP Illustrated: TCP for transactions, HTTP, NNTP, and the UNIX domain protocols
Author: W. Richard Stevens
Publisher: Addison-Wesley Professional
ISBN:
Category : Computers
Languages : en
Pages : 360
Book Description
TCP/IP Illustrated, Volume 3 covers four major topics of great importance to anyone working TCP/IP. It contains the first thorough treatment of TCP for transactions, commonly known as T/TCP, an extension to TCP that makes client-server transactions faster and more efficient. Next, the book covers two popular applications of T/TCP, the very hot topic of HTTP (the Hypertext Transfer Protocol), the foundation for the World Wide Web, and NNTP (the Network News Transfer Protocol), the basis for the Usenet news system. Both of these topics have increased in significance as the Internet has exploded in size and usage. Finally, the book covers UNIX Domain Protocols, protocols that are used heavily in UNIX implementations.

Foundations of Python Network Programming
Author: John Goerzen
Publisher: Apress
ISBN: 1430230045
Category : Computers
Languages : en
Pages : 361
Book Description
This second edition of Foundations of Python Network Programming targets Python 2.5 through Python 2.7, the most popular production versions of the language. Python has made great strides since Apress released the first edition of this book back in the days of Python 2.3. The advances required new chapters to be written from the ground up, and others to be extensively revised. You will learn fundamentals like IP, TCP, DNS and SSL by using working Python programs; you will also be able to familiarize yourself with infrastructure components like memcached and message queues. You can also delve into network server designs, and compare threaded approaches with asynchronous event-based solutions. But the biggest change is this edition's expanded treatment of the web. The HTTP protocol is covered in extensive detail, with each feature accompanied by sample Python code. You can use your HTTP protocol expertise by studying an entire chapter on screen scraping and you can then test lxml and BeautifulSoup against a real-world web site. The chapter on web application programming now covers both the WSGI standard for component interoperability, as well as modern web frameworks like Django. Finally, all of the old favorites from the first edition are back: E-mail protocols like SMTP, POP, and IMAP get full treatment, as does XML-RPC. You can still learn how to code Python network programs using the Telnet and FTP protocols, but you are likely to appreciate the power of more modern alternatives like the paramiko SSH2 library. If you are a Python programmer who needs to learn the network, this is the book that you want by your side.
