MaraDNS
MaraDNS is an open-source (BSD licensed) Domain Name System (DNS) implementation, which acts as either a caching, recursive, or authoritative nameserver. Features MaraDNS has a string library, which is buffer overflow resistant and has its own random number generator. While MaraDNS does not directly support BIND zone files, its zone file format is similar and a converter to convert from BIND's zone file format is included. MaraDNS runs as an unprivileged user inside of a chroot environment, while MaraDNS specifies the user and group to run as by user-ID, Simon Burnet has made a patch that makes it possible to supply a username MaraDNS can add both IP records and the corresponding PTR "reverse DNS lookup" record. It can be used as a master DNS server, and, with some caveats, as a slave DNS server. MaraDNS currently does not support DNSSEC because of a lack of money for the developer to implement it using the LibTom library. Deadwood includes built-in "DNS wall" filtering (to prot ...

Comparison Of DNS Server Software
This article presents a comparison of the features, platform support, and packaging of many independent implementations of Domain Name System (DNS) name server software. Servers compared Each of these DNS servers is an independent implementation of the DNS protocols, capable of resolving DNS names for other computers, publishing the DNS names of computers, or both. Excluded from consideration are single-feature DNS tools (such as proxies, filters, and firewalls) and redistributions of servers listed here (many products repackage BIND, for instance, with proprietary user interfaces). DNS servers are grouped into several categories of specialization of servicing domain name system queries. The two principal roles, which may be implemented either uniquely or combined in a given product are: * Authoritative server: authoritative name servers publish DNS mappings for domains under their ''authoritative'' control. Typically, a company (e.g. "Acme Example Widgets") would provide its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix-like
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems. One of the key features of Unix-like systems is their ability to support multiple users and processes simultaneously. This allows users to run multipl ...

Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Domain Name System
The Domain Name System (DNS) is a hierarchical and distributed naming system for computers, services, and other resources in the Internet or other Internet Protocol (IP) networks. It associates various information with domain names assigned to each of the associated entities. Most prominently, it translates readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols. The Domain Name System has been an essential component of the functionality of the Internet since 1985. The Domain Name System delegates the responsibility of assigning domain names and mapping those names to Internet resources by designating authoritative name servers for each domain. Network administrators may delegate authority over sub-domains of their allocated name space to other name servers. This mechanism provides distributed and fault tolerance, fault-tolerant service and was designed to avoid a single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BSD License
BSD licenses are a family of permissive free software licenses, imposing minimal restrictions on the use and distribution of covered software. This is in contrast to copyleft licenses, which have share-alike requirements. The original BSD license was used for its namesake, the Berkeley Software Distribution (BSD), a Unix-like operating system. The original version has since been revised, and its descendants are referred to as modified BSD licenses. BSD is both a license and a class of license (generally referred to as BSD-like). The modified BSD license (in wide use today) is very similar to the license originally used for the BSD version of Unix. The BSD license is a simple license that merely requires that all code retain the BSD license notice if redistributed in source code format, or reproduce the notice if redistributed in binary format. The BSD license (unlike some other licenses e.g. GPL) does not require that source code be distributed at all. Terms In addition t ...

ZDNet
ZDNET is a business technology news website owned and operated by Red Ventures. The brand was founded on April 1, 1991, as a general interest technology portal from Ziff Davis and evolved into an enterprise IT-focused online publication. History Beginnings: 1991 to 1995 ZDNET began as a subscription-based digital service called "ZiffNet" that offered computing information to users of CompuServe. It featured computer industry forums, events, features and searchable archives. Initially, ZiffNet was intended to serve as a common place to find content from all Ziff-Davis print publications. As such, ZiffNet was an expansion on an earlier online service called PCMagNet for readers of PC Magazine. Launched in 1988, PCMagNet in turn was the evolution of Ziff Davis' first electronic publishing venture, a bulletin board, which launched in 1985. On June 20, 1995, Ziff-Davis announced the consolidation of its online information services under a single name, ''ZD Net''. The service had ...

Domain Name System Security Extensions
The Domain Name System Security Extensions (DNSSEC) are a suite of extension specifications by the Internet Engineering Task Force (IETF) for securing data exchanged in the Domain Name System (DNS) in Internet Protocol (IP) networks. The protocol provides cryptographic authentication of data, authenticated denial of existence, and data integrity, but not availability or confidentiality. Overview The original design of the Domain Name System did not include any security features. It was conceived only as a scalable distributed system. The Domain Name System Security Extensions (DNSSEC) attempt to add security, while maintaining backward compatibility. Request for Comments 3833 documents some of the known threats to the DNS, and their solutions in DNSSEC. DNSSEC was designed to protect applications using DNS from accepting forged or manipulated DNS data, such as that created by DNS cache poisoning. All answers from DNSSEC protected zones are digitally signed. By checking the digit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
