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 problems A systems administrator doesn’t need to know the innards of TCP/IP, but knowing enough to diagnose your own network issues transforms a good sysadmin into a great one.
In a local area network (LAN) or intranet, there are many pieces of hardare trying to gain access to the network transmission media at the same time (i.e., phone lines, coax, wireless, etc.). However, a network cable or wireless transmission frequency can physically only allow one node to use it at a given time. Therefore, there must be some way to regulate which node has control of the medium (a media access control, or MAC, protocol). Ethernet is a MAC protocol; it is one way to regulate physical access to network tranmission media. Ethernet networking is used primarily by networks that are contained within a single physical location. If you need to design, install, and manage a network in such an envronment, i.e., home or small business office, then Ethernet Networking for the Small Office and Professional Home Office will give you an in-depth understanding of the technology involved in an Ethernet network. One of the major goals of this book is to demystify the jargon of networks so that the reader gains a working familiarity with common networking terminology and acronyms. In addition, this books explains not only how to choose and configure network hardware but also provides practical information about the types of network devices and software needed to make it all work. Tips and direction on how to manage an Ethernet network are also provided. This book therefore goes beyond the hardware aspects of Ethernet to look at the entire network from bottom to top, along with enough technical detail to enable the reader to make intelligent choices about what types of transmission media are used and the way in which the various parts of the network are interconnected. - Explains how the Ethernet works, with emphasis on current technologies and emerging trends in gigabit and fast Ethernet, WiFi, routers, and security issues - Teaches how to design and select complementary components of Ethernet networks with a focus on home and small business applications - Discuses the various types of cables, software, and hardware involved in constructing, connecting, operating and monitoring Ethernet networks
