Administer, configure, and monitor Junos in your organization About This Book Get well acquainted with security and routing policies to identify the use of firewall filters. Learn to provide end-user authentication and protect each layer in an enterprise network. A recipe-based guide that will help you configure and monitor Junos OS and basic device operations. Who This Book Is For This book targets network engineers, developers, support personals, and administrators who are working on devices running Junos OS and are looking at automating their organisation's operations. Some understanding about Junos would be necessary What You Will Learn Start using NETCONF RPC standard and understand its usefulness in programming JUNOS Write SLAX scripts to respond to events in the JUNOS environment Automate JUNOS with PyEZ Deal with events in the JUNOS environment, and writing response handlers to deal with them Make the most of automation technologies to help with maintenance and monitoring of JUNOS Use the Ansible framework to extend the automation functionality of Junos In Detail The JUNOS Automation Cookbook is a companion guide for the complex field of automating tasks on JUNOS devices. With a foundation in industry-standrd XML, JUNOS provides an ideal environment for programmatic interation, allowing you to build upon the capabilities provided by Juniper, with your own original code. You will begin by learning about, and setting up, the industry-standard NETCONF remote procedure call mechanisms on your device. After initial setup, you'll walk through SLAX - Juniper's foundation scripting language - for manipulating XML representations of JUNOS concepts and elements. You'll learn how to write your own SLAX scripts to customise the operating environment, and also how to write proactive event handlers that deal with situations as they happen. You'll then delve into PyEZ - Juniper's bridging framework to make automation accessible to Python code - allowing you to build automation applications in the popular scripting language. You'll witness some examples of how to write applications that can monitor configuration changes, implement BGP security policies and implement ad-hoc routing protocols, for those really tricky situations. You'll also leaarn how asynchronous I/O frameworks like Node.js can be used to implement automation applications that present an acceptable web interface. Along with way, you'll explore how to make use of the latest RESTful APIs that JUNOS provides, how to visualize aspects of your JUNOS network, and how to integrate your automation capabilities with enterprise-wide orchestration systems like Ansible. By the end of the book, you'll be able to tackle JUNOS automation challenges with confidence and understanding, and without hassle. Style and Approach A guide that will cover all the automation tools along with steps on leveraging these tools

This suspenseful true story of a drug cartel hitman who got away with murder after murder in California's Central Valley over three decades reveals how the criminal justice system fails our most vulnerable immigrant communities. On the surface, fifty-eight-year-old Jose Martinez didn't seem evil or even that remarkable—just a regular neighbor, good with cars and devoted to his family. But in between taking his children to Disneyland and visiting his mom, Martinez was also one of the most skilled professional killers police had ever seen. He tracked one victim to one of the wealthiest corners of America, a horse ranch in Santa Barbara, and shot him dead in the morning sunlight, setting off a decades-long manhunt. He shot another man, a farmworker, right in front of his young wife as they drove to work in the fields. The widow would wait decades for justice. Those were murders for hire. Others he killed for vengeance. How did Martinez manage to evade law enforcement for so long with little more than a slap on the wrist? Because he understood a dark truth about the criminal justice system: if you kill the "right people"—people who are poor, who aren't white, and who don't have anyone to speak up for them—you can get away with it. Melding the pacing and suspense of a true crime thriller with the rigor of top-notch investigative journalism, The Devil's Harvest follows award-winning reporter Jessica Garrison's relentless search for the truth as she traces the life of this assassin, the cops who were always a few steps behind him, and the families of his many victims. Drawing upon decades of case files, interrogation transcripts, on-the-ground reporting, and Martinez's chilling handwritten journals, The Devil's Harvest uses a gripping and often shocking narrative to dig into one of the most important moral questions haunting our politically divided nation today: Why do some deaths—and some lives—matter more than others? "Meticulously researched and tightly woven, The Devil's Harvest is an important story because it tells us that if [this] can happen in one place, then it can happen in any place. And that's damn scary." —Michael Connelly, New York Times bestselling author of The Closers, The Lincoln Lawyer, and The Night Fire
