Opis Network Administrators Survival Guide: Network Administrators Survival Guide solves many common network administration problems by providing administrators with an all-in-one practical guide to supporting Cisco networks using freeware tools. It provides the explanation of particular issues, its significance for the administrator, and the installation and configuration process for the tool. The solutions are Cisco-centric and more detailed and accurate than generic information available online. Each chapter is broadly based on a network administration function. It starts with an overview of the topic, followed by the methodology involved to accomplish that function. This includes the tools available, why they are the right choices, and their installation, configuration, and usage methods. For any given function, this book covers both Windows- and Linux-based tools, as appropriate. This will benefit a wider reader base, as both operating systems are used in the networking community. Most of the Windows-based tools offer the advantage of GUI for ease of use. On the other hand, Linux-based tools are command-line based and can be used in automated scripts. Both are significant for network administrators. At the end of every chapter is a list that covers the name, function, operating system, and website details of all the tools discussed. The all-in-one practical guide to supporting your Cisco network
