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.
