LCFG
LCFG stands for "Local ConFiGuration system". Developed at the University of Edinburgh beginning around 1993, it is "a system for automatically installing and managing the configuration of large numbers of computer systems. It is particularly suitable for sites with very diverse and rapidly changing configurations". System architectureAnderson, Paul; Scobie, Alastair. (2002) * The configuration of the entire site is described in a set of source files, held on a central server. Note that one source file does not (necessarily) correspond to one machine; a source file typically describes one aspect of the overall configuration, such as "parameters specific to student machines", or "parameters specific to Scientific Linux machines". An individual parameter may be affected by more than one source file. * The source files are compiled into individual profiles. One profile corresponds to one machine, and the profile contains all the configuration parameters necessary to recreate the conf ...

Comparison Of Open Source Configuration Management Software
This is a comparison of notable free and open-source configuration management software, suitable for tasks like server configuration, orchestration and infrastructure as code typically performed by a system administrator. Basic properties "Verify mode" refers to having an ability to determine whether a node is conformant with a guarantee of not modifying it, and typically involves the exclusive use of an internal language supporting read-only mode for all potentially system-modifying operations. " Mutual auth" refers to the client verifying the server and vice versa. "Agent" describes whether additional software daemons are required. Depending on the management software these agents are usually deployed on the target system or on one or many central "controller" servers. Although "Agent-less" = "No" is colored red and might seem to be a negative, in fact having an agent can be considered quite advantageous to many. Consider the impact if an agent-less tool loses connectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quattor
Quattor is a generic open-source tool-kit used to install, configure, and manage computers. Quattor was originally developed in the framework of European Data Grid project (2001-2004). Since its first release in 2003, Quattor has been maintained and extended by a volunteer community of users and developers, primarily from the community of grid system administrators. The Quattor tool-kit, like other configuration management systems, reduces the staff required to maintain a cluster and facilitates reliable change management. However, three unique features make it particularly attractive for managing grid resources: * Federated Management: The open, modular nature of the tool-kit permits system administrators at different institutes to share the management of their distributed resources. * Shared Configuration and Management Efficiency: Quattor encourages the re-use of configuration information in such a way that it can be distributed and used with little or no modification at differen ...

University Of Edinburgh
The University of Edinburgh ( sco, University o Edinburgh, gd, Oilthigh Dhùn Èideann; abbreviated as ''Edin.'' in post-nominals) is a public research university based in Edinburgh, Scotland. Granted a royal charter by King James VI in 1582 and officially opened in 1583, it is one of Scotland's four ancient universities and the sixth-oldest university in continuous operation in the English-speaking world. The university played an important role in Edinburgh becoming a chief intellectual centre during the Scottish Enlightenment and contributed to the city being nicknamed the " Athens of the North." Edinburgh is ranked among the top universities in the United Kingdom and the world. Edinburgh is a member of several associations of research-intensive universities, including the Coimbra Group, League of European Research Universities, Russell Group, Una Europa, and Universitas 21. In the fiscal year ending 31 July 2021, it had a total income of £1.176 billion, of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer-aided Maintenance
Computer-aided maintenance (not to be confused with CAM which usually stands for Computer Aided Manufacturing) refers to systems that utilize software to organize planning, scheduling, and support of maintenance and repair. A common application of such systems is the maintenance of computers, either hardware or software, themselves. It can also apply to the maintenance of other complex systems that require periodic maintenance, such as reminding operators that preventive maintenance is due or even predicting when such maintenance should be performed based on recorded past experience. Computer aided configuration The first computer-aided maintenance software came from DEC in the 1980s to configure VAX computers. The software was built using the techniques of artificial intelligence expert systems, because the problem of configuring a VAX required expert knowledge. During the research, the software was called ''R1'' and was renamed '' XCON'' when placed in service. Fundamentally, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
