Book Description

IMAP (the Internet Message Access Protocol) allows clients to access their email on a remote server, whether from the office, a remote location, or a cell phone or other device. IMAP is powerful and flexible, but it’s also complicated to set up; it’s more difficult to implement than POP3 and more error-prone for both client and server.

The Book of IMAP offers a detailed introduction to IMAP and POP3, the two protocols that govern all modern mail servers and clients. You’ll learn how the protocols work as well as how to install, configure, and maintain the two most popular open source mail systems, Courier and Cyrus.

Authors Peer Heinlein and Peer Hartleben have set up hundreds of mail servers and offer practical hints about troubleshooting errors, migration, filesystem tuning, cluster setups, and password security that will help you extricate yourself from all sorts of tricky situations. You’ll also learn how to:

• Create and use shared folders, virtual domains, and user quotas
• Authenticate user data with PAM, MySQL, PostgreSQL, and LDAP
• Handle heavy traffic with load balancers and proxies
• Use built-in tools for server analysis, maintenance, and repairs
• Implement complementary webmail clients like Squirrelmail and Horde/IMP
• Set up and use the Sieve email filter

Thoroughly commented references to the POP and IMAP protocols round out the book, making The Book of IMAP an essential resource for even the most experienced system administrators. Download Now »

There’s plenty of documentation on installing and configuring the Apache web server, but where do you find help for the day-to-day stuff, like adding common modules or fine-tuning your activity logging? That’s easy. The new edition of the Apache Cookbook offers you updated solutions to the problems you’re likely to encounter with the new versions of Apache.

Written by members of the Apache Software Foundation, and thoroughly revised for Apache versions 2.0 and 2.2, recipes in this book range from simple tasks, such installing the server on Red Hat Linux or Windows, to more complex tasks, such as setting up name-based virtual hosts or securing and managing your proxy server. Altogether, you get more than 200 timesaving recipes for solving a crisis or other deadline conundrums, with topics including:

• Security
• Aliases, Redirecting, and Rewriting
• CGI Scripts, the suexec Wrapper, and other dynamic content techniques
• Error Handling
• SSL
• Performance

This book tackles everything from beginner problems to those faced by experienced users. For every problem addressed in the book, you will find a worked-out solution that includes short, focused pieces of code you can use immediately. You also get explanations of how and why the code works, so you can adapt the problem-solving techniques to similar situations. Download Now »

Book Description

Border Gateway Protocol (BGP) is the routing protocol used to exchange routing information across the Internet. It makes it possible for ISPs to connect to each other and for end-users to connect to more than one ISP. BGP is the only protocol that is designed to deal with a network of the Internet’s size, and the only protocol that can deal well with having multiple connections to unrelated routing domains.

This book is a guide to all aspects of BGP: the protocol, its configuration and operation in an Internet environment, and how to troubleshooting it. The book also describes how to secure BGP, and how BGP can be used as a tool in combating Distributed Denial of Service (DDoS) attacks. Although the examples throughout this book are for Cisco routers, the techniques discussed can be applied to any BGP-capable router.

The topics include:

• Requesting an AS number and IP addresses
• Route filtering by remote ISPs and how to avoid this
• Configuring the initial BGP setup
• Balancing the available incoming or outgoing traffic over the available connections
• Securing and troubleshooting BGP
• BGP in larger networks: interaction with internal routing protocols, scalability issues
• BGP in Internet Service Provider networks

Book Description

If you’ve ever been responsible for a network, you know that sinkingfeeling: your pager has gone off at 2 a.m., the network is broken, and you can’t figure out why by using a dial-in connection from home. You drive into the office, dig out your protocol analyzer, and spend the next fourhours trying to put things back together before the staff shows up for work.

When this happens, you often find yourself looking at the low-level guts of the Internet protocols: you’re deciphering individual packets, trying to figure out what is (or isn’t) happening. Until now, the only real guide to the protocols has been the Internet RFCs–and they’re hardlywhat you want to be reading late at night when your network is down. There hasn’t been a good book on the fundamentals of IP networking aimed at network administrators–until now.

Internet Core Protocols: The Definitive Guide contains all the information you need for low-level network debugging. It provides thorough coverage of the fundamental protocols in the TCP/IP suite: IP, TCP, UDP, ICMP, ARP (in its many variations), and IGMP. (The companion volume, Internet Application Protocols: The Definitive Guide,provides detailed information about the commonly used application protocols, including HTTP, FTP, DNS, POP3, and many others). It includes many packet captures, showing you what to look for and how to interpret all the fields. It has been brought up to date with the latest developments in real-world IP networking.

The CD-ROM included with the book contains Shomiti’s “Surveyor Lite,” a packet analyzer that runs on Win32 systems, plus the original RFCs, should you need them for reference. Download Now »
