    Open Source Solutions for Building Your Own Storage Area Network and Network Attached Storage Author, Balakrishnan Subramanian A Data Science Foundation White Paper May 2020 --------------------------------------------------- Data Science Foundation Data Science Foundation, Atlantic Business Centre, Atlantic Street, Altrincham, WA14 5NQ Tel: 0161 926 3641 Email: [email protected] Web: www.datascience.foundation Registered in England and Wales 4th June 2015, Registered Number 9624670 www.datascience.foundation Copyright 2016 - 2017 Data Science Foundation 1. INTRODUCTION Generally, Storage solutions can be grouped into following four categories: SoHo NAS systems, Cloud-based/object solutions, Microsoft Storage Server solutions, Enterprise NAS (Networked Attached Storage) and Storage Area Network (SAN) solutions. Enterprise NAS and SAN solutions are generally closed systems offered by traditional vendors like EMC and NetApp with a very large price tag, so many businesses are looking at Open Source solutions to meet their needs. This is a collection of links and brief descriptions of Open Source storage solutions currently available. Open Source of course means it’s free to use and modify, however some projects have do commercially supported versions as well for enterprise customers who require it. 1. Factors for choosing Storage Solutions When you are in the need of Storage solutions for managing your own infrastructure in your private Data Center, there are many offerings but selecting the right one depends upon your requirement. Factors involved in selecting a Storage type Budget Type of Data that you want to store Scaling concerns and Usage pattern In this article, we will be discussing two different methods (i.e. NAS and SAN), these two methods define the Structure of the storage, it is important to choose the right one based upon your use case and type of data.

  • How to Create a Custom Live CD for Secure Remote Incident Handling in the Enterprise
    How to Create a Custom Live CD for Secure Remote Incident Handling in the Enterprise Abstract This paper will document a process to create a custom Live CD for secure remote incident handling on Windows and Linux systems. The process will include how to configure SSH for remote access to the Live CD even when running behind a NAT device. The combination of customization and secure remote access will make this process valuable to incident handlers working in enterprise environments with limited remote IT support.

  • Pluggable Authentication Modules
    Who this book is written for This book is for experienced system administrators and developers working with multiple Linux/UNIX servers or with both UNIX and Pluggable Authentication Windows servers. It assumes a good level of admin knowledge, and that developers are competent in C development on UNIX-based systems. Pluggable Authentication Modules PAM (Pluggable Authentication Modules) is a modular and flexible authentication management layer that sits between Linux applications and the native underlying authentication system. The PAM framework is widely used by most Linux distributions for authentication purposes. Modules Originating from Solaris 2.6 ten years ago, PAM is used today by most proprietary and free UNIX operating systems including GNU/Linux, FreeBSD, and Solaris, following both the design concept and the practical details. PAM is thus a unifying technology for authentication mechanisms in UNIX. This book provides a practical approach to UNIX/Linux authentication. The design principles are thoroughly explained, then illustrated through the examination of popular modules. It is intended as a one-stop introduction and reference to PAM. What you will learn from this book From Technologies to Solutions • Install, compile, and configure Linux-PAM on your system • Download and compile third-party modules • Understand the PAM framework and how it works • Learn to work with PAM’s management groups and control fl ags • Test and debug your PAM confi guration Pluggable Authentication Modules • Install and configure the pamtester utility

It sends requests from the client?s end to the server end and conveys data from the server to the client. Well, that is enough to know about the HTTP protocol if you are a regular internet user. If you are a server administrator or a network manager or host your own website on an Nginx server, you need to know more about HTTP, HTTP/2.0, and how to enable HTTP/2.0 in the Nginx server. How to manage Linux container registries | Enable Sysadmin [3] If we have a close look at LEGO® products, we can see that they are all made of the same building blocks. However, the composition of these blocks is the key differentiator for whether we are building a castle or space ship. It's pretty much the same for Podman, and its sibling projects Buildah, Skopeo, and CRI-O. However, instead of recycled plastic, the building blocks for our container tools are made of open source code. Sharing these building blocks allows us to provide rock-solid, enterprise-grade container tools.
