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.

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. Until now. DNSSEC Mastery will have DNS administrators running DNSSEC with the industry-standard BIND server in hours instead of weeks. You will: •Understand what DNSSEC gives you, and what it doesn't •Configure your servers to resist attack. •Verify your environment supports modern DNS •Debug DNSSEC and the Chain of Trust •Configure your server to resolve DNSSEC •Conceal zone data with NSEC3 •Cryptographically sign your zones, and attach them to the Chain of Trust •Let BIND automatically maintain DNSSEC for you •Roll over keys to maintain security •Implement DNSSEC on private networks •Use DNSSEC to validate self-signed SSL certificates, ending your dependence on Certificate Authorities And more! DNSSEC Mastery transforms DNS from a security risk to a solution.

Unix-like operating systems have a primitive access control system. The root account can do anything. Other users are peasants with only minimal system access. This worked fine in UNIX’s youth, but today, system administration responsibilities are spread among many people and applications. Each person needs a tiny slice of root’s power. Sudo lets you divide root’s monolithic power between the people who need it, with accountability and auditability. Sudo Mastery will teach you to: * design a sudo policy rather than slap rules together * simplify policies with lists and aliases * use non-Unix information sources in policies * configure alternate sudo policies * manage shell environments * verify system integrity and perform intrusion detection * have a common sudo policy across your server farm * manage sudo policies via LDAP * log and debug sudo * log and replay full sudo sessions * use authentication systems other than passwords While many people use sudo, most use only a small part of it’s features. Chances are, you’re doing it wrong. Master sudo with Sudo Mastery.

Pluggable Authentication Modules: Threat or Menace? PAM is one of the most misunderstood parts of systems administration. Many sysadmins live with authentication problems rather than risk making them worse. PAM’s very nature makes it unlike any other Unix access control system. If you have PAM misery or PAM mysteries, you need PAM Mastery! With PAM Mastery, you’ll understand:   the different versions of PAM  the intricacies of Linux-PAM and OpenPAM  how PAM policies make decisions  how to debug PAM  the most frequently seen PAM modules  Linux-PAM extended controls and substacks  time-based one-time passwords  using SSH keys for more than SSH  password quality testing  policies from CentOS, Debian, and FreeBSD  and more!  Transform PAM from a headache to an ally with PAM Mastery

“I think we’re gonna need a bigger web server.” OpenBSD has a solid reputation for security and stability. It’s well known for the OpenSMTPd mail server, the LibreSSL cryptography library, and the PF packet filter. But nobody ever talks about the load balancer, or the web server. Until now. The httpd web server provides a fast, stable, secure environment for your web applications. The relayd load balancer lets you distribute Internet application load across multiple hosts. Between the two, you can slash hundreds of thousands of dollars off the cost of building, deploying, and managing applications. With Httpd and Relayd Mastery you’ll learn how to: • set up web sites • configure software to run in a chroot • run dozens or hundreds of sites on one host • dynamically reconfigure sites with Lua patterns • manage site logs • maintain free, globally-valid SSL certificates • improve performance with SSL stapling • install and maintain two-server clusters • distribute traffic between any number of hosts • stop worrying about old SSL versions and bad crypto algorithms Slash the amount of time you spend futzing with web servers.

Cisco routers are the standard devices used to connect companies to the Internet. They are highly reliable and robust, and support anything from small connections to huge circuits used by telephone companies. Cisco Routers for the Desperate is a brief, meaty introduction to Cisco routers that will make a competent systems administrator comfortable with the Cisco environment, teach them how to troubleshoot problems, and take them through the basic tasks of router maintenance and integration into an existing network. When a system almost never breaks, the tech support people responsible for it do not have the opportunity to learn about it. When it does break, repairs can take a long time simply because the people responsible don't know what to do! This book is designed for the desperate support people who just need to get the darn thing working again -- and fast. This compact book is designed to be read once, and then left on top of the router until something breaks. It's for people who don't really want to know a huge amount about routers but who do want to provide reliable network services.

Unlike packet sniffers that require you to reproduce network problems in order to analyze them, flow analysis lets you turn back time as you analyze your network. You'll learn how to use open source software to build a flow-based network awareness system and how to use network analysis and auditing to address problems and improve network reliability. You'll also learn how to use a flow analysis system; collect flow records; view, filter, and report flows; present flow records graphically; and use flow records to proactively improve your network. Network Flow Analysis will show you how to:
 <ul>
<li>Identify network, server, router, and firewall problems before they become critical</li>
<li>Find defective and misconfigured software</li>
<li>Quickly find virus-spewing machines, even if they're on a different continent</li>
<li>Determine whether your problem stems from the network or a server</li>
<li>Automatically graph the most useful data</li>
</ul>
 And much more. Stop asking your users to reproduce problems. Network Flow Analysis gives you the tools and real-world examples you need to effectively analyze your network flow data. Now you can determine what the network problem is long before your customers report it, and you can make that silly phone stop ringing.
