Pro Linux Embedded Systems

Today, Linux is included with nearly every embedded platform. Embedded developers can take a more modern route and spend more time tuning Linux and taking advantage of open source code to build more robust, feature-rich applications. While Gene Sally does not neglect porting Linux to new hardware, modern embedded hardware is more sophisticated than ever: most systems include the capabilities found on desktop systems. This book is written from the perspective of a user employing technologies and techniques typically reserved for desktop systems.

• Modern guide for developing embedded Linux systems
• Shows you how to work with existing Linux embedded system, while still teaching how to port Linux
• Explains best practices from somebody who has done it before

What you’ll learn

• The anatomy of an embedded Linux project
• How to create an embedded Linux development environment
• How to configure and build an embedded Linux kernel
• How to configure and build open source projects for embedded systems
• How to minimize resources and boot times
• What resources are available in open source to help you build your project

The Definitive Guide to CentOS

CentOS is just like Red Hat, but without the price tag and with the virtuous license. When belts have to be tightened, we want to read about an OS with all the features of a commercial Linux variety, but without the pain. The Definitive Guide to CentOS is the first definitive reference for CentOS and focuses on CentOS alone, the workhorse Linux distro, that does the heavy lifting in small and medium-size enterprises without drawing too much attention to itself.

• Provides tutorial and hands-on learning but is also designed to be used as a reference
• Bases all examples on real-world tasks that readers are likely to perform
• Serves up hard-won examples and hints and tips from the author's experiences of CentOS in production

What you’ll learn

• See why CentOS is an ideal platform for deploying services on the same level as Redhat Enterprise Linux without the cost.
• Prepare and install a CentOS server from scratch.
• Install and configure core services.
• Follow best practices for managing and administering the server and its services.
• Integrate enterprise features in CentOS/Red Hat networks.
• And finally, move away from Fedora, which has great features, but is not meant to be a server OS!

Linux Email

Many businesses want to run their email servers on Linux for greater control and flexibility of corporate communications, but getting started can be complicated. The attractiveness of a free-to-use and robust email service running on Linux can be undermined by the apparent technical challenges involved. Some of the complexity arises from the fact that an email server consists of several components that must be installed and configured separately, then integrated together.

This book gives you just what you need to know to set up and maintain an email server. Unlike other approaches that deal with one component at a time, this book delivers a step-by-step approach across all the server components, leaving you with a complete working email server for your small business network.

Starting with a discussion on why you should even consider hosting your own email server, the book covers setting up the mail server. We then move on to look at providing web access, so that users can access their email out of the office. After this we look at the features you'll want to add to improve email productivity: virus protection, spam detection, and automatic email processing. Finally we look at an essential maintenance task: backups.

Written by professional Linux administrators, the book is aimed at technically confident users and new and part-time system administrators. The emphasis is on simple, practical and reliable guidance.

Based entirely on free, Open Source software, this book will show you how to set up and manage your email server easily.

What you will learn from this book? You will:

• Install Postfix mail transfer agent and set up an environment to send and receive email messages
• Implement the two standard email retrieval protocol services - POP3 and IMAP - for your mail server using Courier-IMAP
• Configure an easy-to-use open source email client - Mozilla Thunderbird - on your system
• Install and maintain an efficient webmail solution for your clients with SquirrelMail
• Prevent usernames and passwords from being sent in plain text, instead encrypting them to avoid eavesdroppers from intercepting valid account details
• Configure relay permissions for static as well as dynamic IP addresses, and protect your Postfix server from relay abuse
• Create mail filters, sort your incoming mail into separate folders, pre-process your mail, start any programs upon mail arrival and selectively forward certain incoming mail automatically to someone using Procmail
• Automatically filter all the mails for spam by integrating SpamAssassin with your mail server
• Secure your mail server by configuring an email virus scanning system with Clam AV
• Create an ongoing scheduled backup to recover from catastrophic loss of service in case of a major hardware or software malfunction
