Samba-3 by Example
Samba-3 by Example Practical Exercises in Successful Samba Deployment John H. Terpstra May 27, 2009 ABOUT THE COVER ARTWORK The cover artwork of this book continues the freedom theme of the first edition of \Samba-3 by Example". The history of civilization demonstrates the fragile nature of freedom. It can be lost in a moment, and once lost, the cost of recovering liberty can be incredible. The last edition cover featured Alfred the Great who liberated England from the constant assault of Vikings and Norsemen. Events in England that finally liberated the common people came about in small steps, but the result should not be under-estimated. Today, as always, freedom and liberty are seldom appreciated until they are lost. If we can not quantify what is the value of freedom, we shall be little motivated to protect it. Samba-3 by Example Cover Artwork: The British houses of parliament are a symbol of the Westminster system of government. This form of government permits the people to govern themselves at the lowest level, yet it provides for courts of appeal that are designed to protect freedom and to hold back all forces of tyranny. The clock is a pertinent symbol of the importance of time and place. The information technology industry is being challenged by the imposition of new laws, hostile litigation, and the imposition of significant constraint of practice that threatens to remove the freedom to develop and deploy open source software solutions. Samba is a software solution that epitomizes freedom of choice in network interoperability for Microsoft Windows clients. -

Chapter 2: Installing Samba on a Unix System
,ch02.26865 Page 31 Friday, November 19, 1999 3:28 PM Chapter 2 2 Installing Samba on a Unix System Now that you know what Samba can do for you and your users, it’s time to get your own network set up. Let’s start with the installation of Samba itself on a Unix system. When dancing the samba, one learns by taking small steps. It’s just the same when installing Samba; we need to teach it step by step. This chapter will help you to start off on the right foot. For illustrative purposes, we will be installing the 2.0.4 version of the Samba server on a Linux* system running version 2.0.31 of the kernel. However, the installation steps are the same for all of the platforms that Samba supports. A typical installa- tion will take about an hour to complete, including downloading the source files and compiling them, setting up the configuration files, and testing the server. Here is an overview of the steps: 1. Download the source or binary files. 2. Read the installation documentation. 3. Configure a makefile. 4. Compile the server code. 5. Install the server files. 6. Create a Samba configuration file. 7. Test the configuration file. 8. Start the Samba daemons. 9. Test the Samba daemons. * If you haven’t heard of Linux yet, then you’re in for a treat. Linux is a freely distributed Unix-like oper- ating system that runs on the Intel x86, Motorola PowerPC, and Sun Sparc platforms. The operating sys- tem is relatively easy to configure, extremely robust, and is gaining in popularity. -

Daemon Threads
Daemon threads Your operating system has various threads that provide services to user threads. That’s their sole purpose: to serve user threads. The term originated with the Unix operating system, but most operating systems have them in one form or another, with slightly differing properties. Examples are: • In Unix, crond is job scheduler, running jobs in the background. Line printer daemon lpd manages printer spooling. • In Windows systems, daemons are called Windows services. One such is Prefetch-and-Superfetch, which caches frequently used files and other components to RAM. The DNS Client resolves domain names to IP addresses. • In Java, the garbage collector is a daemon, continuously finding objects that cannot be reached from the Java program and putting the memory they occupy on a “free list” so the memory can be used for some other purpose. We won’t be writing Java programs that use daemon threads. (Look at the next page for a realistic use of a daemon thread.) Nevertheless, a basic understanding of daemons, including where the word came from, is useful. The basic property of a Java daemon thread In Java, suppose your main-program thread is named t. Suppose t creates and starts threads t1, t2, and t3. Suppose also that it has made t3 a daemon (we show how to do this later). Here is the basic difference be- tween t3 and the other threads: When thread t, t1, and t2 die (i.e. complete method run()), daemon thread t3 is killed. Thus, as long as one normal thread is alive, daemon threads stay alive. -

Mengenal Sistim Operasi *BSD
Mengenal Sistim Operasi *BSD Ada banyak sekali tulisan-tulisan yang membahas tentang BSD, baik tulisan mengenai sejarah, system administrasi, sampai penggunaan BSD kepada end-user sebagai desktop. Tulisan ini memperkenalkan BSD sebagai alternatif lain dari Linux untuk memenuhi kebutuhan akan UNIX-like operating system di Indonesia. Dalam tulisan ini pula, dibahas mengenai beberapa hal yang membedakan antara Linux dan BSD, namun tidak memutuskan mana yang paling baik, karena untuk menentukan mana operating system yang paling baik digunakan adalah Anda sendiri. Daftar Isi 1. Sejarah 2. Distribusi Varian BSD 3. Model Pengembangan 4. Integrasi System 5. Software-software di BSD 6. System Administrasi 7. File System 8. Lain-lain 9. Kesimpulan Sejarah Hampir semua orang telah mendengar Linux saat ini. Namun apa itu BSD? BSD adalah singkatan dari Berkeley Software Distribution. BSD pertama kali dibangun dan dikembangkan oleh Computer System Research Group (CSRG) di University of California at Berkeley (UCB), BSD pertama kali keluar pada akhir 1977 sebagai paket tambahan dan patch dari AT&T UNIX version 6, yang mana waktu itu beroperasi pada mesin PDP-11 minicomputer. BSD pada akhirnya banyak memberikan kontribusi berharga pada pengembangan UNIX secara umum. Ada banyak fitur yang pertama kali diperkenalkan oleh BSD dan beberapa diadopsi dari AT&T dan vendor-vendor lainnya. BSD dibuat, dikembangkan, dan digunakan secara BEBAS sebagai perlawanan terhadap lisensi UNIX yang dimiliki oleh AT&T dan oleh karena itu BSD mempunyai lisensi tersendiri yang memungkinkan setiap orang bebas melakukan pengembangan, dan menggunakan source code BSD. Pada tahun 1993, 4.4BSD dirilis sebagai sebuah Operating System yang utuh. Untuk sejarah lengkap BSD di CSRG, mulai sejarah dari jaman kuda, motivasi orang-orang yang pertama kali mengerjakannya, sampai perseteruan lisensi dan hak cipta dengan AT&T, saya mereferensikan Anda untuk membaca tulisan yang dibuat oleh Kirk McKusick, “Twenty Years of Berkeley Unix“. -
SMB Analysis
NAP-3 Microsoft SMB Troubleshooting Rolf Leutert, Leutert NetServices, Switzerland © Leutert NetServices 2013 www.wireshark.ch Server Message Block (SMB) Protokoll SMB History Server Message Block (SMB) is Microsoft's client-server protocol and is most commonly used in networked environments where Windows® operating systems are in place. Invented by IBM in 1983, SMB has become Microsoft’s core protocol for shared services like files, printers etc. Initially SMB was running on top of non routable NetBIOS/NetBEUI API and was designed to work in small to medium size workgroups. 1996 Microsoft renamed SMB to Common Internet File System (CIFS) and added more features like larger file sizes, Windows RPC, the NT domain service and many more.

Understanding the Linux Kernel, 3Rd Edition by Daniel P
1 Understanding the Linux Kernel, 3rd Edition By Daniel P. Bovet, Marco Cesati ............................................... Publisher: O'Reilly Pub Date: November 2005 ISBN: 0-596-00565-2 Pages: 942 Table of Contents | Index In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks. The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does. This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. The book focuses on the following topics: • Memory management, including file buffering, process swapping, and Direct memory Access (DMA) • The Virtual Filesystem layer and the Second and Third Extended Filesystems • Process creation and scheduling • Signals, interrupts, and the essential interfaces to device drivers • Timing • Synchronization within the kernel • Interprocess Communication (IPC) • Program execution Understanding the Linux Kernel will acquaint you with all the inner workings of Linux, but it's more than just an academic exercise. -

It is a common misconception that systemd is somehow limited to desktop distributions. This is hardly true; similarly to Jóhann B.
