Consists of 117 sample solutions for configuring sendmail functions running on a Unix computer that system administrators customize for their specific needs. The tasks discussed include accepting mail from other hosts, passing outbound mail to a relay, masquerading with LDAP, routing mail to special purpose mailers, blocking spam with the access database, and patching to close security holes. The examples are based on sendmail 8.12 taken from Red Hat Linux 7.3 and 8.0 and Solaris 8. Annotation ©2004 Book News, Inc., Portland, OR

Linux Kernel Development details the design and implementation of the Linux kernel, presenting the content in a manner that is beneficial to those writing and developing kernel code. While the book discusses topics that are theoretical, it does so with the goal of assisting programmers so they better understand the topics and become more efficient and productive in their coding.The book discusses the major subsystems and features of the Linux kernel, including design and implementation, their purpose and goals, and their interfaces. Important computer science and operating system design details are also addressed. The book covers the Linux kernel from both angles - theoretical and applied - which should appeal to both types of readers.The author is involved in Linux kernel development, so the latest kernel version is detailed, as the author has access to the not-yet-released development releases.Specific topics covered will include: all the important algorithms, relevant subsystems, process management, scheduling, time management and timers, system call interface, memory addressing, memory management, paging strategies, caching layers, VFS, kernel synchronization, and signals.

UNIX se ha convertido en uno de los sistemas operativos más populares en entornos industriales, académicos y, recientemente, incluso domésticos y brinda al usuario un conjunto de herramientas muy variado y completo. La mayor parte de los programas estandar en UNIX estan escritos en lenguaje C, y hace uso de unas piezas basicas conocidas como llamadas al sistema (system calls). El conjunto de llamadas al sistema es la interfaz entre el sistema operativo y el programador que utiliza sus recursos y constituye el nucleo de estudio de este libro, junto con tecnicas de programacion avanzada que nos permitiran aprovechar al maximo la potencia y flexibilidad de UNIX. El libro esta estructurado en tres partes, de acuerdo con la siguiente distribucion de capitulos: -Introduccion. Parte 1. El sistema de ficheros. -Arquitectura del sistema de ficheros. -Manejo de ficheros ordinarios. -Manejo de directorios y ficheros especiales. Parte 2. Procesos e hilos. -Estructura de un proceso. -Gestion de procesos e hilos. -Señales y funciones de tiempo. -Perfilado, contabilidad y depuracion. Parte 3. Comunicacion entre procesos. -Comunicacion mediante tuberias. -Comunicacion local entre procesos e hilos. -Comunicaciones en red. Para ayudar a la comprension del texto se utilizan alrededor de 90 programas de ejemplo elegidos no solo por su interes didactico, sino tambien porque muchos de ellos responden a la funcionalidad de programas estandar UNIX. Estos programas pueden servirle al lector como elementos de referencia para la construccion de aplicaciones o de nuevas herramientas del sistema.

Samba is a cross-platform triumph: it turns a Unix or Linux system into a file and print server for Microsoft Windows network clients.This book describes all the options for Samba's configuration file in quick-reference format. It also contains command-line options and related information on the use of the Samba daemons (smbd, nmbd, and winbindd) and the utilities in the Samba distribution. The current edition covers Samba 2.x and the most important features of 3.0, which was under development as this book went to print. New options pertain to Samba's acting as a primary domain controller and as a domain member server, its support for the use of Windows NT/2000/XP authentication and filesystem security on the host Unix system, and access to shared files and printers from Unix clients. System administrators who are familiar with Samba and want a handy reminder of how to administer it without the bulk of a full-sized book will find this pocket reference invaluable.

If you''re familiar with Unix administration, TCP/IP networking, and other common Unix servers, and you want to learn how to deploy Samba, this book is ideal for you. With this book as a guide, you can quickly configure a basic Samba server and then move on to learn about Samba''s more exotic features, including those new to Samba 3.0. The topics in this book are approached from both an experienced Unix user and an administrator''s point of view, to help you optimize Samba. Samba is an efficient file and print server that enables you to get the most out of your computer hardware. In Samba 3.0, many important features have been added, particularly in the realm of domain administration and membership, such as improved support for membership in Windows 200x domains and a wider array of authentication options. Samba also boasts several advanced features with which you can perform very complex tasks. For instance, Samba can control an NT domain, burn CD-Rs with drag-and-drop operations from the client, and function as part of a network backup system. The Samba dance after which the server is named is known for its liveliness, and the server is similarly energetic and dynamic. So join inyou may make a misstep or two, but this book will help you avoid making too many, and you''ll soon be doing the (TCP/IP) Samba along with the best!

In introducing Unix-based mail systems, Levine notes that qmail has quietly become one of the most widely used Internet applications since its release in 1998. This much-published technical writer covers the basics of how qmail works; moving to qmail from its sendmail predecessor; and advanced aspects including virtual domains and the users database. He includes problem-solving tips, a sample script, and online resources. The author co-chairs the Internet Research Task Force's Anti-Span Research Group.
