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. -

A Sense of Time for Node.Js: Timeouts As a Cure for Event Handler Poisoning
A Sense of Time for Node.js: Timeouts as a Cure for Event Handler Poisoning Anonymous Abstract—The software development community has begun to new Denial of Service attack that can be used against EDA- adopt the Event-Driven Architecture (EDA) to provide scalable based services. Our Event Handler Poisoning attack exploits web services. Though the Event-Driven Architecture can offer the most important limited resource in the EDA: the Event better scalability than the One Thread Per Client Architecture, Handlers themselves. its use exposes service providers to a Denial of Service attack that we call Event Handler Poisoning (EHP). The source of the EDA’s scalability is also its Achilles’ heel. Multiplexing unrelated work onto the same thread re- This work is the first to define EHP attacks. After examining EHP vulnerabilities in the popular Node.js EDA framework and duces overhead, but it also moves the burden of time sharing open-source npm modules, we explore various solutions to EHP- out of the thread library or operating system and into the safety. For a practical defense against EHP attacks, we propose application itself. Where OTPCA-based services can rely on Node.cure, which defends a large class of Node.js applications preemptive multitasking to ensure that resources are shared against all known EHP attacks by making timeouts a first-class fairly, using the EDA requires the service to enforce its own member of the JavaScript language and the Node.js framework. cooperative multitasking [89]. An EHP attack identifies a way to defeat the cooperative multitasking used by an EDA-based Our evaluation shows that Node.cure is effective, broadly applicable, and offers strong security guarantees. -
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. -
Shared File Systems: Determining the Best Choice for Your Distributed SAS® Foundation Applications Margaret Crevar, SAS Institute Inc., Cary, NC
Paper SAS569-2017 Shared File Systems: Determining the Best Choice for your Distributed SAS® Foundation Applications Margaret Crevar, SAS Institute Inc., Cary, NC ABSTRACT If you are planning on deploying SAS® Grid Manager and SAS® Enterprise BI (or other distributed SAS® Foundation applications) with load balanced servers on multiple operating systems instances, , a shared file system is required. In order to determine the best shared file system choice for a given deployment, it is important to understand how the file system is used, the SAS® I/O workload characteristics performed on it, and the stressors that SAS Foundation applications produce on the file system. For the purposes of this paper, we use the term "shared file system" to mean both a clustered file system and shared file system, even though" shared" can denote a network file system and a distributed file system – not clustered. INTRODUCTION This paper examines the shared file systems that are most commonly used with SAS and reviews their strengths and weaknesses. SAS GRID COMPUTING REQUIREMENTS FOR SHARED FILE SYSTEMS Before we get into the reasons why a shared file system is needed for SAS® Grid Computing, let’s briefly discuss the SAS I/O characteristics. GENERAL SAS I/O CHARACTERISTICS SAS Foundation creates a high volume of predominately large-block, sequential access I/O, generally at block sizes of 64K, 128K, or 256K, and the interactions with data storage are significantly different from typical interactive applications and RDBMSs. Here are some major points to understand (more details about the bullets below can be found in this paper): SAS tends to perform large sequential Reads and Writes. -
Samba's AD DC: Samba 4.2 and Beyond
Samba's AD DC: Samba 4.2 and Beyond Presented by Andrew Bartlett of Catalyst // 2014-09 About me ● Andrew Bartlett ● Samba Team member since 2001 ● Working on the AD DC since 2006 ● These views are my own, but I do with to thank: – My employer: Catalyst – My fellow Samba Team members Open Source Technologies Samba's AD DC ● The combination of many years work – File server – Print server – Active Directory Domain controller – (and many other features) ● First Release Dec 2012 ● Now on the road to Samba 4.2 – Due for RC1 on Monday Sep 22 Re-opening the heart of the network ● Samba's AD DC brings open source to the heart of the network again ● Samba has long provided a Domain Controller – But without support for Group Policy and other AD features like Kerberos ● Organizations again have a practical choice other than Microsoft Windows The flexibility to innovate ● Open Source lets you do more ● Just as Samba is in many NAS devices, including NETGEAR's ReadyNAS ● Samba inside Catalyst's print server – No CALs, multi-device access ● Imagine – What if was also an AD DC? – Instant branch office solution – Perhaps managed from the cloud? Breaking vendor lock in ● Samba can migrate to and from Microsoft Windows based AD domains – Without loss of data – Without password resets or domain joins ● Samba 4.0 can upgrade existing Samba 3.x domains to AD – And you can even migrate that to a Microsoft Windows AD if you want to – We won't hold you against your will! Uses Native Microsoft Admin tools ● Microsoft Management Console snap-ins – In general, fully -
