Stop waiting for the network team!If basic TCP/IP was hard, network administrators couldn't do it. Servers give sysadmins a incredible visibility into the network-once they know how to unlock it. Most sysadmins don't need to understand window scaling, or the differences between IPv4 and IPv6 echo requests, or other intricacies of the TCP/IP protocols. You need only enough to deploy your own applications and get easy support from the network team.This book teaches you:¿How modern networks really work¿The essentials of TCP/IP¿The next-generation protocol, IPv6¿The right tools to diagnose network problems, and how to use them¿Troubleshooting everything from the physical wire to DNS¿How to see the traffic you send and receive¿Connectivity testing¿How to communicate with your network team to quickly resolve problemsA systems administrator doesn't need to know the innards of TCP/IP, but knowing enough to diagnose your own network issues will transforms a good sysadmin into a great one.Fungi are among the most networked creatures in the world. If a mushroom can do it, so can you!

Network and system administration usually refers to the skill of keeping computers and networks running properly. But in truth, the skill needed is that of managing complexity. This book describes the science behind these complex systems, independent of the actual operating systems they work on. It provides a theoretical approach to systems administration that: saves time in performing common system administration tasks. allows safe utilization of untrained and trained help in maintaining mission-critical systems. allows efficient and safe centralized network administration. Managing Human-Computer Networks: Will show how to make informed analyses and decisions about systems, how to diagnose faults and weaknesses Gives advice/guidance as to how to determine optimal policies for system management Includes exercises that illustrate the key points of the book The book provides a unique approach to an old problem and will become a classic for researchers and graduate students in Networking and Computer Science, as well as practicing system managers and system administrators.

Computer systems administrators supervise the day-to-day operation of such physical computer devices as central data storage, printers, scanners, and routers. They install programs, hook up cables, identify problems, and update equipment and software. In 2016, U.S. News and World Report ranked the occupation the eighth-best technology job, and future employment projections show growing demand for workers with the right skills. This title explains the job and how it fits into the overall field of information technology. It focuses on what the job is like and also covers the bases of education, certification, and experience that employers will look for.

In this book, you will gain extensive hands-on experience installing and configuring a firewall. You will also learn how to allow access to key Web services while maintaining your organization's security, as well as how to implement firewall-to-firewall virtual private networks (VPNs). You will learn how to build a firewall to protect your network; provide access to HTTP and FTP services on the Internet, and implement publicly accessible servers without compromising security. Furthermore, throughout the book, extensive hands-on examples provide you with practical experience in establishing security with firewalls. Examples include, but are not limited to: Installing and configuring Check Point FireWall-1; scanning to validate configuration using ISS Internet Scanner; configuring the firewall to support simple and complex Web services; setting up a packet filtering router; enhancing firewall configurations to support split-DNS; authenticating remote users; and protecting browsers and servers with a proxy-based firewall. · Install and configure proxy-based and stateful-filtering firewalls · Protect internal IP addresses with NAT and deploy a secure DNS architecture · Develop an Internet/intranet security policy to protect your organization's systems and data · Reduce your susceptibility to an attack by deploying firewalls, data encryption and decryption and other countermeasures

Information Technology: An Introduction for Today’s Digital World introduces undergraduate students to a wide variety of concepts they will encounter throughout their IT studies and careers. The book covers computer organization and hardware, Windows and Linux operating systems, system administration duties, scripting, computer networks, regular expressions, binary numbers, the Bash shell in Linux, DOS, managing processes and services, and computer security. It also gives students insight on IT-related careers, such as network and web administration, computer forensics, web development, and software engineering. Suitable for any introductory IT course, this classroom-tested text presents many of the topics recommended by the ACM Special Interest Group on IT Education (SIGITE). It offers a far more detailed examination of the computer than current computer literacy texts, focusing on concepts essential to all IT professionals—from operating systems and hardware to information security and computer ethics. The book highlights Windows/DOS and Linux with numerous examples of issuing commands and controlling the operating systems. It also provides details on hardware, programming, and computer networks. Ancillary Resources The book includes laboratory exercises and some of the figures from the text online. PowerPoint lecture slides, answers to exercises, and a test bank are also available for instructors.
