OpenBSD is widely used as the basis for critical DNS servers, routers, firewalls, and more. With this book, you'll learn the intricacies of the platform, the technical details behind certain design decisions, and best practices. This edition has been updated for OpenBSD 5.3, including new coverage of OpenBSD's boot system, security features like W^X and ProPolice, and advanced networking techniques. You'll also learn how to: manage network traffic with VLANs, trunks, IPv6, and the PF packet filter; make software management quick and effective using the ports and packages system; give users only the access they need with groups, sudo, and chroots; configure OpenBSD's secure implementations of SNMP, DHCP, NTP, hardware sensors, and more; and customize the installation and upgrade processes for your network and hardware, or build a custom OpenBSD release.

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.

A detailed and complete guide to exporting, collecting, analyzing, and understanding network flows to make managing networks easier. Network flow analysis is the art of studying the traffic on a computer network. Understanding the ways to export flow and collect and analyze data separates good network administrators from great ones. The detailed instructions in Network Flow Analysis teach the busy network administrator how to build every component of a flow-based network awareness system and how network analysis and auditing can help address problems and improve network reliability. Readers learn what flow is, how flows are used in network management, and how to use a flow analysis system. Real-world examples illustrate how to best apply the appropriate tools and how to analyze data to solve real problems. Lucas compares existing popular tools for network management, explaining why they don't address common real-world issues and demonstrates how, once a network administrator understands the underlying process and techniques of flow management, building a flow management system from freely-available components is not only possible but actually a better choice than much more expensive systems.

Discover the future of Vim with Neovim: a fork of Vim that includes a built-in terminal emulator that will transform your workflow. Whether you choose to switch to Neovim or stick with Vim 8, you'll be a better developer. A serious tool for programmers and web developers, no other text editor comes close to Vim for speed and efficiency. Make Vim the centerpiece of a Unix-based IDE as you discover new ways to work with Vim 8 and Neovim in more than 20 hands-on tips. Execute tasks asynchronously, allowing you to continue in Vim while linting, grepping, building a project, or running a test suite. Install plugins to be loaded on startup - or on-demand when you need them - with Vim 8's new package support. Save and restore sessions, enabling you to quit Vim and restart again while preserving your window layout and undo history. Use Neovim as a drop-in replacement for Vim - it supports all of the features Vim 8 offers and more, including an integrated terminal that lets you quickly perform interactive commands. And if you enjoy using tmux and Vim together, you'll love Neovim's terminal emulator, which lets you run an interactive shell in a buffer. The terminal buffers fit naturally with Vim's split windows, and you can use Normal mode commands to scroll, search, copy, and paste. On top of all that: Neovim's terminal buffers are scriptable. With Vim at the core of your development environment, you'll become a faster and more efficient developer. What You Need: You'll need a Unix-based environment and an up-to-date release of Vim (8.0 or newer). For the tips about running a terminal emulator, you'll need to install Neovim.
