Networking for System Administrators

＂One of the best technical writers in the networking and security environments.＂

- Midwest Book Review

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 core of IPv4 and 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 sysadmin 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.

The first edition of Networking for System Administrators unlocked networking for hundreds of thousands of sysadmins. This second edition promises the same, and more!
