Networking for System Administrators
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:
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.
Fungi are among the most networked creatures in the world. If a mushroom can do it, so can you!

DNS is one of the oldest protocols on the Internet, and was designed for a network without hostile users. Anyone who wants to break into a network starts by investigating the target’s Domain Name Service. DNS Security Extensions, or DNSSEC, hardens DNS and brings it into the 21st century. But learning DNSSEC requires wading through years of obsolete tutorials, dead ends, and inscrutable standards.
DNSSEC Mastery will have DNS administrators running DNSSEC with the industry-standard BIND server in hours instead of weeks. You will:
And more! DNSSEC Mastery transforms DNS from a security risk to a solution.

Network Flow Analysis
Blaming the network is easy. It’s traditional. And it’s (usually) wrong.
Servers have log files, performance monitors, and other tools to assess and record system and application behavior. Traditional network devices have one LED on each port, and if you’re lucky the LED blinks when somehing happens. Maybe you have tools to tell you how busy an interface is, but generally a network device is an unreadable black box. Network Flow Analysis opens the black box, demonstrating how to use the freely-available flow-tools software and the capabilities of your existing hardware to assess, analyze, and debug your network.

A network administrator’s abilities are as good as his awareness of his network. Flow analysis is the industry-standard method of collecting and recording network traffic. Flow analysis lets you see what types of traffic passed between hosts, without having to reproduce the problem.
Flow export and analysis transforms network administration from a stomach-churning mix of guesswork, issue reproduction, and head-scratching to a fact-based science that lets you focus on resolving problems at their source.
Network administrators: When a problem is yours, own it. When a problem isn’t yours, prove it.

Cisco Routers for the Desperate
It’s 3AM. Do you know why your router is on fire?
Cisco routers are the industry standard, to which all other routers are compared. Whether you love them or hate them, you still must live with them. While they’re generally robust and reliable, when a Cisco router breaks someone needs to fix it. If you’re in IT, when they say someone they mean you.
This book provides a brief introduction to Cisco routers, with a tight focus on what you need to know to get the router up and working in the shortest amount of time. Reading this book once will give you the knowledge on how your router and internet circuit work. Leaving it on top of the router for reference during a crisis will give you a step-by-step guide to troubleshooting when things go wrong.
Once you understand routers, managing switches isn’t much harder. This 2nd Edition will help you upgrade, manage, and operate Cisco switching hardware, from the tiny 12-port models to the monster backbone devices.
Most Cisco books with real technical content are heavy enough to stun a moose with. This book is small enough to read in a couple of hours and light enough to carry around in your laptop bag.
You’ll learn how to upgrade your router, back up your router configuration, implement a private WAN, and more!
“This book isn’t a reference – it’s a survival guide, a ‘break glass in case of emergency’ safety harness… What I found remarkable was how it was obviously written for people like me – who have little interest in router management but whose jobs depend on the consistent, trusted functioning of such infrastructure.”
