Linux Terminal Server Project
Linux Terminal Server Project (LTSP) is a free and open source terminal server for Linux that allows many people to simultaneously use the same computer. Applications run on the server with a terminal known as a thin client (also known as an X terminal) handling input and output. Generally, terminals are low-powered, lack a hard disk and are quieter and more reliable than desktop computers because they do not have any moving parts. This technology is useful in schools as it allows the school to provide pupils access to computers without purchasing or upgrading expensive desktop machines. Improving access to computers becomes less costly as thin client machines can be older computers that are no longer suitable for running a full desktop OS. Even a relatively slow CPU with as little as 128 MB of RAM can deliver excellent performance as a thin client. In addition, the use of centralized computing resources means that more performance can be gained for less money through upgrade ...

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Mount (computing)
Mounting is a process by which a computer's operating system makes files and directories on a storage device (such as hard drive, CD-ROM, or network share) available for users to access via the computer's file system. In general, the process of mounting comprises the operating system acquiring access to the storage medium; recognizing, reading, and processing file system structure and metadata on it before registering them to the virtual file system (VFS) component. The location in the VFS to which the newly mounted medium was registered is called a mount point; when the mounting process is completed, the user can access files and directories on the medium from there. An opposite process of mounting is called unmounting, in which the operating system cuts off all user access to files and directories on the mount point, writes the remaining queue of user data to the storage device, refreshes file system metadata, then relinquishes access to the device, making the storage device ...

ISCSI
Internet Small Computer Systems Interface or iSCSI ( ) is an Internet Protocol-based storage networking standard for linking data storage facilities. iSCSI provides block-level access to storage devices by carrying SCSI commands over a TCP/IP network. iSCSI facilitates data transfers over intranets and to manage storage over long distances. It can be used to transmit data over local area networks (LANs), wide area networks (WANs), or the Internet and can enable location-independent data storage and retrieval. The protocol allows clients (called ''initiators'') to send SCSI commands ( ''CDBs'') to storage devices (''targets'') on remote servers. It is a storage area network (SAN) protocol, allowing organizations to consolidate storage into storage arrays while providing clients (such as database and web servers) with the illusion of locally attached SCSI disks. It mainly competes with Fibre Channel, but unlike traditional Fibre Channel which usually requires dedicated cabling, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel VPro
Intel vPro technology is an umbrella marketing term used by Intel for a large collection of computer hardware technologies, including VT-x, VT-d, Trusted Execution Technology (TXT), and Intel Active Management Technology (AMT). When the vPro brand was launched (circa 2007), it was identified primarily with AMT, thus some journalists still consider AMT to be the essence of vPro. vPro features Intel vPro is a brand name for a set of PC hardware features. PCs that support vPro have a vPro-enabled processor, a vPro-enabled chipset, and a vPro-enabled BIOS as their main elements. A vPro PC includes: * Multi-core, multi-threaded Xeon or Core processors. * Intel Active Management Technology (Intel AMT), a set of hardware-based features targeted at businesses, allow remote access to the PC for management and security tasks, when an OS is down or PC power is off. Note that AMT is not the same as Intel vPro; AMT is only one element of a vPro PC. * Remote configuration technology for AMT, ...

Filesystem In Userspace
Filesystem in Userspace (FUSE) is a software interface for Unix and Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a bridge to the actual kernel interfaces. FUSE is available for Linux, FreeBSD, OpenBSD, NetBSD (as puffs), OpenSolaris, Minix 3, macOS, and Windows. FUSE is free software originally released under the terms of the GNU General Public License and the GNU Lesser General Public License. History The FUSE system was originally part of ''AVFS'' (''A Virtual Filesystem''), a filesystem implementation heavily influenced by the translator concept of the GNU Hurd. It superseded Linux Userland Filesystem, and provided a translational interface using in libfuse1. FUSE was originally released under the terms of the GNU General Public License and the GNU Lesser General Public License, later also reimple ...

NX Technology
NX technology, commonly known as ''NX'' or NoMachine, is a proprietary cross-platform software application for remote access, desktop sharing, virtual desktop (on Linux only) and file transfer between computers. It is developed by the Luxembourg-based company NoMachine. NX's design was derived from the Differential X Protocol Compressor project (DXPC). In 2003, the compression and transport protocol NX was created to improve the performance of the native X display protocol so it could be used over slow connections such as dial-up modems. It wrapped remote connections in SSH sessions for encryption. The core compression technology was released under the GNU GPL2 license (NX 1) for Linux servers, whilst other components such as the NX Server and NX Client programs remained proprietary, on February 14, 2003. The last update to this open-source version was released in 2012. In 2010, the company announced they would be releasing the technology under a proprietary license. Starti ...

GNOME Display Manager
GNOME Display Manager (GDM) is a display manager (a graphical login manager) for the windowing systems X11 and Wayland. The X Window System by default uses the XDM display manager. However, resolving XDM configuration issues typically involves editing a configuration file. GDM allows users to customize or troubleshoot settings without having to resort to a command line. Users can pick their session type on a per-login basis. GDM 2.38.0 is the last version that features customization with themes; subsequent releases do not support themes. Software architecture GDM is a display manager that implements all significant features required for managing attached and remote displays. GDM was written from scratch and does not contain any XDM or X Consortium code. Components GDM comprises the following components: * Chooser – a program used to select a remote host for managing a display remotely on the attached display (gdm-host-chooser) * Greeter – the graphical login window (pro ...

KDE Display Manager
KDE Display Manager (KDM) is a display manager (a graphical login program) developed by KDE for the windowing systems X11. KDE Display Manager was based on the source code of X display manager and was the default display manager of the KDE Software Compilation, until it was retired in KDE Plasma 5 in favour of SDDM. KDM allowed the user to choose a desktop environment or window manager at login. KDM used the Qt application framework. It is configurable via KDE's System Settings; its appearance can be customized by the user. The default KDM login screen had a list of users. Each entry was comprised in the user's username, personal name (if available), and an icon. Next to the list is a greeting and a picture. One of the customization options is to replace the picture with an analog clock. From this screen the user can also run a user management tool, shut down or reboot the computer, or restart the X Window System. See also * getty – a non-graphical login program * Simple ...

X Display Manager (program Type)
In the X Window System, an X display manager is a graphical login manager which starts a login session on an X server from the same or another computer. A display manager presents the user with a login screen. A session starts when a user successfully enters a valid combination of username and password. When the display manager runs on the user's computer, it starts the X server before presenting the user the login screen, optionally repeating when the user logs out. In this condition, the DM realizes in the X Window System the functionality of and on character-mode terminals. When the display manager runs on a remote computer, it acts like a telnet server, requesting username and password and starting a remote session. X11 Release 3 introduced display managers in October 1988 with the aim of supporting the standalone X terminals, just coming onto the market. Various display managers continue in routine use to provide a graphical login prompt on standalone computer works ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tunnelling Protocol
In computer networks, a tunneling protocol is a communication protocol which allows for the movement of data from one network to another. It involves allowing private network communications to be sent across a public network (such as the Internet) through a process called encapsulation. Because tunneling involves repackaging the traffic data into a different form, perhaps with encryption as standard, it can hide the nature of the traffic that is run through a tunnel. The tunneling protocol works by using the data portion of a packet (the payload) to carry the packets that actually provide the service. Tunneling uses a layered protocol model such as those of the OSI or TCP/IP protocol suite, but usually violates the layering when using the payload to carry a service not normally provided by the network. Typically, the delivery protocol operates at an equal or higher level in the layered model than the payload protocol. Uses A tunneling protocol may, for example, allow a foreig ...
