Networking for Systems Administrators

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.
