This practical guide teaches you how to implement effective network protection by using your own customized firewall solution. Based on extensive practical experience, this book distills a unique set of scenario based scripts and guidelines for a proven firewall solution, into one succinct and precise book. This book shows you how to implement Linux firewalls and Quality of Service using practical examples from very small to very large networks.

After giving us a background of network security, the book moves on to explain the basic technologies we will work with, namely netfilter, iproute2, NAT and l7-filter. These form the crux of building Linux firewalls and QOS.Providing only necessary theoretical background, the book takes a practical approach, presenting case studies and plenty of illustrative examples.

FreeBSD the powerful, flexible, and free Unix-like operating system is the preferred server for many enterprises. But it can be even trickier to use than either Unix or Linux, and harder still to master.

Absolute FreeBSD, 2nd Edition is your complete guide to FreeBSD, written by FreeBSD committer Michael W. Lucas. Lucas considers this completely revised and rewritten second edition of his landmark work to be his best work ever; a true product of his love for FreeBSD and the support of the FreeBSD community. Absolute FreeBSD, 2nd Edition covers installation, networking, security, network services, system performance, kernel tweaking, filesystems, SMP, upgrading, crash debugging, and much more, including coverage of how to:

* Use advanced security features like packet filtering, virtual machines, and host-based intrusion detection.
* Build custom live FreeBSD CDs and bootable flash.
* Manage network services and filesystems.
* Use DNS and set up email, IMAP, web, and FTP services for both servers and clients.
* Monitor your system with performance-testing and troubleshooting tools.
* Run diskless systems.
* Manage schedulers, remap shared libraries, and optimize your system for your hardware and your workload.
* Build custom network appliances with embedded FreeBSD.
* Implement redundant disks, even without special hardware.
* Integrate FreeBSD-specific SNMP into your network management system.

Whether you’re just getting started with FreeBSD or you’ve been using it for years, you’ll find this book to be the definitive guide to FreeBSD that you’ve been waiting for.

Hong’s straightforward style makes it easy for the do-it-yourself crowd to build a server quickly using the ports collection (a software package management system). But rather than wade through the thousands of ports available, Hong focuses on the most popular and useful ones. Each package is treated as an independent project (and given a difficulty rating), so readers can dip into the book at any point to install just the packages they need, when they need them.

The book’s modules cover topics like:

* Running common FreeBSD admin commands and tasks.
* Managing the FreeBSD ports collection.
* Installing third-party apps like Apache, Courier-IMAP, SpamAssassin, CUPS, Cyrus SASL, MediaWiki, and WordPress.
* Setting up MySQL, NTP, ISC DHCP, ISC BIND DNS, PHP, OpenLDAP, OpenSSH, OpenSSL, and OpenVPN.

Appendixes explain user management, backup/restore, and network protocols.

Building a Server with FreeBSD 7 will have readers running their own server loaded with useful modules in no time, with a minimum of hassle.

The success of Wikipedia has proven just how effective wikis can be for
collaborative editing on a large scale-larger than anyone originally
thought possible. This book shows you how to install, use, manage, and
extend a wiki using MediaWiki-the wiki engine used to power Wikipedia.

from simple to those of increasing complexity and evolve from theory to
case study. You’ll learn wiki terminology and how to create user
accounts and new pages, use wiki links, and find your way around the

development projects and how their capabilities ideally suit a specific
environment and audience. You’ll quickly come to discover why wikis are
a valuable addition for any organization that wants to increase
productivity using web-based collaboration tools. What you will learn
from this book:

- When to use wikis instead of a more formal content management system
- What to look for when evaluating wikis in order to avoid unexpected
pitfalls
- How to install MediaWiki using Apache, PHP, MySQL®, and other
alternatives
- How wikitext allows you to edit content from any web browser and
create links to other wiki pages
- Ways to comment on pages, move them, track changes, and syndicate
wiki pages with RSS Who this book is for This book is for programmers,
developers, information architects, designers, and content authors who
are looking to use wikis to improve team productivity. Knowledge of
