This book contains 36 chapters and is structured to facilitate readers to grasp concepts, understand implementation procedures, learn command syntax, configuration files and daemons involved, and understand basic troubleshooting. The 36 chapters are divided into three key areas: UNIX Fundamentals, HP-UX System Administration and HP-UX Network Administration. These chapters cover topics that are on HP s recommended certification courses UNIX Fundamentals, System and Network Administration I, System and Network Administration II, and HP-UX for Experienced UNIX System Administrators as well as on official exam objectives list. 1.UNIX Fundamentals (chapters 1 to 6, and 22) covers the basics of UNIX and HP-UX. Most information is not specific to a particular UNIX flavor, rather, includes general UNIX concepts, file manipulation and security techniques, vi editor, shell and awk programming, basic commands and other essential topics. Unlike many other similar books, a chapter on shell scripting is presented after covering HP-UX System Administration area. This is done purposely to provide readers with practical examples based on the knowledge they gain from UNIX Fundamentals and HP-UX System Administration chapters. 2.HP-UX System Administration (chapters 7 to 21) covers the HP-UX-specific system administration concepts and topics including server hardware information and mass storage stack; virtualization technologies and HP-UX installation; software and patch management; user and group administration; LVM and file system administration; EVFS and swap management; system shutdown and startup procedures; kernel configuration and management techniques; backup and restore functions; printer and print request management, job automation and process control; and system logging and performance monitoring. 3.HP-UX Network Administration (chapters 23 to 36) covers HP-UX network and security administration concepts and topics such as OSI and TCP/IP reference models; network hardware overview and LAN interface administration; IP subnetting and routing techniques; basic network testing and troubleshooting; internet services and sendmail; time synchronization (NTP) and resource sharing (NFS, AutoFS and CIFS) services; naming (DNS, NIS and LDAP) services and automated installation techniques; and high-availability concepts and system security tools and practices. Throughout the book figures, tables, screen shots and examples are given for explanation purposes. The book includes 863 exam review questions with answers.

This practical introduction to OpenLDAP for Application Developers emphasizes how to get things done, going into Lightweight Directory Access Protocol (LDAP) theory only to answer practical questions. It demystifies OpenLDAP, providing a solid understanding of how to use its directory and covering building directory services, integrating directory services, and developing directory-enabled PHP or Python applications. Readers need only basic Linux system administration experience, not LDAP experience. Open-source OpenLDAP directory server is included in all major Linux distributions; many open-source and proprietary applications can use OpenLDAP's services. Client applications use LDAP to connect to OpenLDAP, search the directory, and (if authorized) modify and manipulate records. Most often used to provide network-based authentication services for users, LDAP servers have many other uses: address book, DNS database, organizational tool, even network object store for applications.

This book is an easy-to-read guide to using IPCop in a variety of different roles within the network. The book is written in a very friendly style that makes this complex topic easy and a joy to read. It first covers basic IPCop concepts, then moves to introduce basic IPCop configurations, before covering advanced uses of IPCop. This book is for both experienced and new IPCop users. IPCop is a powerful, open source, Linux based firewall distribution for primarily Small Office Or Home (SOHO) networks, although it can be used in larger networks. It provides most of the features that you would expect a modern firewall to have, and what is most important is that it sets this all up for you in a highly automated and simplified way. This book is an easy introduction to this popular application. After introducing and explaining the foundations of firewalling and networking and why they're important, the book moves on to cover using IPCop, from installing it, through configuring it, to more advanced features, such as configuring IPCop to work as an IDS, VPN and using it for bandwidth management. While providing necessary theoretical background, the book takes a practical approach, presenting sample configurations for home users, small businesses, and large businesses. The book contains plenty of illustrative examples. Chapter 1 briefly introduces some firewall and networking concepts. The chapter introduces the roles of several common networking devices and explains how firewalls fit into this. Chapter 2 introduces the IPCop package itself, discussing how IPCop's red/orange/blue/green interfaces fit into a network topology. It then covers the configuration of IPCop in other common roles, such as those of a web proxy, DHCP, DNS, time, and VPN server. Chapter 3 covers three sample scenarios where we learn how to deploy IPCop, how IPCop interfaces connect to each other and to the network as a whole. Chapter 4 covers installing IPCop. It outlines the system configuration required to run IPCop, and explains the configuration required to get IPCop up and running. In Chapter 5, we will learn how to employ the various tools IPCop provides us with to administrate, operate, troubleshoot, and monitor our IPCop firewall Chapter 6 starts off with explaining the need for an IDS in our system and then goes on to explain how to use the SNORT IDS with IPCop. Chapter 7 introduces the VPN concept and explains how to set up an IPSec VPN configuration for a system. Special focus is laid on configuring the blue zone - a secured wireless network augmenting the security of a wireless segment, even one already using WEP or WPA. Chapter 8 demonstrates how to manage bandwidth using IPCop making use of traffic shaping techniques and cache management. The chapter also covers the configuration of the Squid web proxy and caching system. Chapter 9 focuses on the vast range of add-ons available to configure IPCop to suit our needs. We see how to install add-ons and then learn more about common add-ons like SquidGuard, Enhanced Filtering, Blue Access, LogSend, and CopFilter. Chapter 10 covers IPCop security risks, patch management and some security and auditing tools and tests. Chapter 11 outlines the support IPCop users have in the form of mailing lists and IRC. The book is suitable for anyone interested in securing their networks with IPCop - from those new to networking and firewalls, to networking and IT Professionals with previous experience of IPCop. No knowledge of Linux or IPCop is required.

Like the first edition of this book, the second edition also covers three main objectives to provide a comprehensive resource to individuals, including novice, IT/Non-HP-UX administrators, and HP-UX administrators who intend to take the new HP Certified Systems Administrator exam HP0-095 and pass it; to provide a quick and valuable on-the-job resource to HP-UX administrators, administrators of other UNIX operating systems, IT managers, programmers, and DBAs working in the HP-UX environment; and to provide an easy-to-understand guide to novice and IT/non-HP-UX administrators who intend to learn HP-UX from the beginning. This book contains 38 chapters and is structured to facilitate readers to grasp concepts, understand implementation procedures, understand basic troubleshooting, learn command syntax, configuration files, and daemons involved.

Each chapter begins with a list of major topics to be covered in the chapter and ends with a summary. Throughout the book, tables, figures, screen shots, and examples are given for explanation purposes. The output generated because of running commands and shell scripts is highlighted in light grey background to differentiate from surrounding text. The book includes several appendices, one of which contains 672 practice exam questions. Answers to practice exam questions and tables of commands, important files, and service daemons are included in appendix area as well.

"Operating System" is the most essential program of all, without which it becomes cumbersome to work with a computer. It is the interface between the hardware and computer users making the computer a pleasant device to use. "The Operating System: Concepts and Techniques" clearly defines and explains the concepts: process (responsibility, creation, living, and termination), thread (responsibility, creation, living, and termination), multiprogramming, multiprocessing, scheduling, memory management (non-virtual and virtual), interprocess communication/synchronization (busy-wait-based, semaphore-based, and message-based), deadlock, and starvation. Real-life techniques presented are based on UNIX, Linux, and contemporary Windows. The book has briefly discussed agent-based operating systems, macro-kernel, microkernel, extensible kernels, distributed, and real-time operating systems. The book is for everyone who is using a computer but is still not at ease with the way the operating system manages programs and available resources in order to perform requests correctly and speedily. High school and university students will benefit the most, as they are the ones who turn to computers for all sorts of activities, including email, Internet, chat, education, programming, research, playing games etc. It is especially beneficial for university students of Information Technology, Computer Science and Engineering. Compared to other university textbooks on similar subjects, this book is downsized by eliminating lengthy discussions on subjects that only have historical value.

Penguin in the Pew clears up the confusion about the terms "free" and "open source," addresses the challenges of hardware compatibility, software interoperability, and whether a migration is really more expensive than an upgrade.

This open access book provides an overview of the work developed within the SODALITE project, which aims at facilitating the deployment and operation of distributed software on top of heterogeneous infrastructures, including cloud, HPC and edge resources. The experts participating in the project describe how SODALITE works and how it can be exploited by end users. While multiple languages and tools are available in the literature to support DevOps teams in the automation of deployment and operation steps, still these activities require specific know-how and skills that cannot be found in average teams. The SODALITE framework tackles this problem by offering modelling and smart editing features to allow those we call Application Ops Experts to work without knowing low level details about the adopted, potentially heterogeneous, infrastructures. The framework offers also mechanisms to verify the quality of the defined models, generate the corresponding executable infrastructural code, automatically wrap application components within proper execution containers, orchestrate all activities concerned with deployment and operation of all system components, and support on-the-fly self-adaptation and refactoring.

An introduction to operating systems, covering processes, states of processes, synchronization, programming methods of synchronization, main memory, secondary storage and file systems. Although the book is short, it covers all the essentials and opens up synchronization by introducing a metaphor: producer--consumer that other authors have employed. The difference is that the concept is presented without the programming normally involved with the concept. The thinking is that using a warehouse, the size of which is the shared variable in synchronization terms, without the programming will aid in understanding to this difficult concept. The book also covers main memory, secondary storage with file systems, and concludes with a brief discussion of the client-server paradigm and the way in which client-server impacts the design of the World-Wide Web.
