Linux Hint [3] This article will demonstrate how to set up FreeBSD 12.0, the latest version, on Zettabyte File System, or ZFS. The method we?ll employ is going to use BSDinstall and consequently allocate all of the disks to host the FreeBSD system. How to Share Files Between Windows and Linux [4] File sharing is the action of sending a file or more from one computer to another. In theory, it?s a simple thing. The process is quite simple and straightforward if both of the computers are running the same operating system. When it?s different, things get a bit complicated. How To Install Firefox on CentOS 8 - idroot [5] In this tutorial, we will show you how to install Firefox on CentOS 8. For those of you who didn?t know, Firefox is the default web browser in a number of Linux distributions and CentOS is one of them. -
THINC: a Virtual and Remote Display Architecture for Desktop Computing and Mobile Devices

ABSTRACT THINC: A Virtual and Remote Display Architecture for Desktop Computing and Mobile Devices Ricardo A. Baratto THINC is a new virtual and remote display architecture for desktop computing. It has been designed to address the limitations and performance shortcomings of existing remote display technology, and to provide a building block around which novel desktop architectures can be built. THINC is architected around the notion of a virtual display device driver, a software-only component that behaves like a traditional device driver, but instead of managing specific hardware, enables desktop input and output to be intercepted, manipulated, and redirected at will. On top of this architecture, THINC introduces a simple, low-level, device-independent representation of display changes, and a number of novel optimizations and techniques to perform efficient interception and redirection of display output. This dissertation presents the design and implementation of THINC. It also intro- duces a number of novel systems which build upon THINC's architecture to provide new and improved desktop computing services. The contributions of this dissertation are as follows: • A high performance remote display system for LAN and WAN environments. -

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. -
Getting Ready for Samba4
Getting Ready for Samba4 Samba Team member Andrew Bartlett explores the world of Samba4, its development status, what you can (and can’t) do with Samba4, and — most importantly– when you can expect to start using Samba4 in a production environment. Andrew Bartlett Thursday, April 3rd, 2008 Ever wanted to run an Active Directory Domain Controller on your Linux server? Did you run a Samba 3.0 DC, but had to move to Active Directory, or worried you might need to? Interested in the leading edge of Samba development, and wondering what the preceding questions mean? Without Samba, Linux, Windows and Macintosh computers could not share files and printers with each other, and networks of windows computers could only use Microsoft’s products to implement consistent user names and passwords across an organisation, something known as domain control. Since Samba was last covered by Linux Magazine in 2002, it seems the whole world has changed. Yet for members of the Samba Team the task remains to provide the Free Software community with a solid implementation of the Common Internet File System (CIFS) protocol, and with that a bridge into the Windows world. It is in that pursuit of interoperability that the Samba Team has continued, soon (at the time of writing) releasing version 3.2.0 of Samba, and alpha releases of Samba4. But Samba4 is more than just a new version of Samba, and more akin to a new development effort. Largely rewritten to handle the problems of interacting with modern versions of Microsoft’s Windows suite, Samba4 has been a storehouse of testing and innovation. -

PRODUCTS COMPANY PARTNERS CUSTOMERS SUPPORT Home > Blog > SysKit Monitor > CredSSP required by server – Solutions CredSSP required by server – Solutions Published: May 16, 2017 Published in: SysKit Monitor Author: Silvio Rahle Failed to connect, CredSSP required by server is an error line returned when trying to connect remotely to a Windows machine using RDP version 6 or newer with the Rdesktop client. It represents a frequent problem for Windows and Linux administrators alike. Rdesktop client is UNIX based client software for Microsoft’s Remote Desktop Protocol. It is commonly used on ReactOS and Linux installations to connect to Windows machines running Remote Desktop Services, which often leads to the CredSSP required by server error. Why does it happen? All Windows clients have a credential cache used for authentication against services in a network called NTLM or Windows NT LAN Manager. RDP supports SSO (single sign-on) authentication enabling a user to log in with a single ID and password to gain access to a connected system. However, Linux clients do not support this type of authentication and they require that credentials are provided, either via a Rdesktop command line or via a login window when initiating the remote session. Linux has Kerberos, which is an authentication mechanism for requesting access to 1 of 5 9/26/17, 9:38 PM CredSSP required by server – Solutions https://www.syskit.com/blog/credssp-required-b...

Collabkit – a Multi-User Multicast Collaboration System Based on VNC
Humboldt-Universität zu Berlin Institut für Informatik Lehrstuhl für Rechnerorganisation und Kommunikation Diplomarbeit CollabKit – A Multi-User Multicast Collaboration System based on VNC Christian Beier 19. April 2011 Gutachter Prof. Dr. Miroslaw Malek Prof. Dr. Jens-Peter Redlich Betreuer Peter Ibach <[email protected]> Abstract Computer-supported real-time collaboration systems offer functionality to let two or more users work together at the same time, allowing them to jointly create, modify and exchange electronic documents, use applications, and share information location-independently and in real-time. For these reasons, such collaboration systems are often used in professional and academic contexts by teams of knowledge workers located in different places. But also when used as computer-supported learning environments – electronic classrooms – these systems prove useful by offering interactive multi-media teaching possibilities and allowing for location-independent collaborative learning. Commonly, computer-supported real-time collaboration systems are realised using remote desktop technology or are implemented as web applications. However, none of the examined existing commercial and academic solutions were found to support concurrent multi-user interaction in an application-independent manner. When used in low-throughput shared-medium computer networks such as WLANs or cellular networks, most of the investigated systems furthermore do not scale well with an increasing number of users, making them unsuitable for multi-user collaboration of a high number of participants in such environments. For these reasons this work focuses on the design of a collaboration system that supports concurrent multi-user interaction with standard desktop applications and is able to serve a high number of users on low-throughput shared-medium computer networks by making use of multicast data transmission. -
