Apparmor
AppArmor ("Application Armor") is a Linux kernel security module that allows the system administrator to restrict programs' capabilities with per-program profiles. Profiles can allow capabilities like network access, raw socket access, and the permission to read, write, or execute files on matching paths. AppArmor supplements the traditional Unix discretionary access control (DAC) model by providing mandatory access control (MAC). It has been partially included in the mainline Linux kernel since version 2.6.36 and its development has been supported by Canonical since 2009. Details In addition to manually creating profiles, AppArmor includes a learning mode, in which profile violations are logged, but not prevented. This log can then be used for generating an AppArmor profile, based on the program's typical behavior. AppArmor is implemented using the Linux Security Modules (LSM) kernel interface. AppArmor is offered in part as an alternative to SELinux, which critics consi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immunix
Immunix is a discontinued commercial operating system that provided host-based application security solutions. The last release of Immunix's Linux distribution was version 7.3 on November 27, 2003. Immunix, Inc. was the creator of AppArmor, an application security system. On May 10, 2005, Novell acquired Immunix, Inc., a long-time partner with Novell. AppArmor was one of Novell's primary interests, and as a result, it was adopted by the company and renamed Novell AppArmor powered by Immunix. In September 2007, Novell laid off the AppArmor team.

Hard Link
In computing, a hard link is a directory entry (in a directory-based file system) that associates a name with a file. Thus, each file must have at least one hard link. Creating additional hard links for a file makes the contents of that file accessible via additional paths (i.e., via different names or in different directories). This causes an alias effect: a process can open the file by any one of its paths and change its content. By contrast, a soft link or “shortcut” to a file is not a direct link to the data itself, but rather a reference to a hard link or another soft link. Every directory is itself a special file, only it contains a list of file names. Hence, multiple hard links to directories are possible, which could create a circular directory structure, rather than a branching structure like a tree. For that reason, some file systems forbid the creation of hard links to directories. POSIX-compliant operating systems, such as Linux, Android, macOS, and the Win ...

Arch Linux
Arch Linux () is an independently developed, x86-64 general-purpose Linux distribution that strives to provide the latest stable versions of most software by following a rolling-release model. The default installation is a minimal base system, configured by the user to only add what is purposely required. Pacman, a package manager written specifically for Arch Linux, is used to install, remove and update software packages. Arch Linux uses a rolling release model, meaning there are no "major releases" of completely new versions of the system; a regular system update is all that is needed to obtain the latest Arch software; the installation images released every month by the Arch team are simply up-to-date snapshots of the main system components. Arch Linux has comprehensive documentation, consisting of a community-run wiki known as the ArchWiki. History Inspired by CRUX, another minimalist distribution, Judd Vinet started the Arch Linux project in March 2002. The name w ...

Debian Version History
Debian releases do not follow a fixed schedule. Recent releases have been made roughly biennially by the Debian Project. The most recent version of Debian is Debian version 11, codename "Bullseye". The next up and coming release of Debian is Debian 12 codename "Bookworm". Debian always has at least three release branches active at any time: "stable", "testing" and "unstable". The stable release is the most recent and up-to-date version of Debian. The testing release contains packages that have been tested from unstable. Testing has significantly more up-to-date packages than stable and is a close version of the future release candidate for stable. The unstable release (also known as sid) is the release where active development takes place. It is the most volatile version of Debian. When the Debian stable branch is replaced with a newer release, the current stable becomes an "oldstable" release. When the Debian stable branch is replaced again, the oldstable release becomes the "o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solus (operating System)
Solus (previously known as Evolve OS) is an independently developed operating system for the x86-64 architecture based on the Linux kernel and a choice of the homegrown Budgie desktop environment, GNOME, MATE or KDE Plasma as the desktop environment. Its package manager, eopkg, is based on the PiSi package management system from Pardus Linux, and it has a semi-rolling release model, with new package updates landing in the stable repository every Friday. The developers of Solus have stated that Solus is intended exclusively for use on personal computers and will not include software that is only useful in enterprise or server environments. History On September 20, 2015, Ikey Doherty announced that "Solus 1.0 will be codenamed Shannon, after the River Shannon in Ireland", indicating that "codenames for releases will continue this theme, using Irish rivers." In July 2016, Solus announced the intention to discard the concept of fixed point releases and to embrace a rolling rele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Libvirt
libvirt is an open-source API, daemon and management tool for managing platform virtualization. It can be used to manage KVM, Xen, VMware ESXi, QEMU and other virtualization technologies. These APIs are widely used in the orchestration layer of hypervisors in the development of a cloud-based solution. Internals libvirt is a C library with bindings in other languages, notably in Python, Perl, OCaml, Ruby, Java, JavaScript (via Node.js) and PHP. libvirt for these programming languages is composed of wrappers around another class/package called libvirtmod. libvirtmod's implementation is closely associated with its counterpart in C/C++ in syntax and functionality. Supported Hypervisors * LXC – lightweight Linux container system * OpenVZ – lightweight Linux container system * Kernel-based Virtual Machine/QEMU (KVM) – open-source hypervisor for Linux and SmartOS * Xen – bare-metal hypervisor * User-mode Linux (UML) – paravirtualized kernel * VirtualBox – hyp ...

Common Unix Printing System
CUPS (formerly an acronym for Common UNIX Printing System) is a modular computer printer, printing system for Unix-like computer operating systems which allows a computer to act as a print server. A computer running CUPS is a Server (computing), host that can accept print jobs from client (computing), client computers, process them, and send them to the appropriate printer. CUPS consists of a print spooler and scheduler, a filter system that converts the print data to a format that the printer will understand, and a backend system that sends this data to the print device. CUPS uses the Internet Printing Protocol (IPP) as the basis for managing print jobs and queue (printing), queues. It also provides the traditional command line interfaces for the System V printing system, System V and Berkeley printing system, Berkeley print systems, and provides support for the Berkeley print system's Line Printer Daemon protocol and limited support for the Server Message Block (SMB) protoc ...

SubDomain
In the Domain Name System (DNS) hierarchy, a subdomain is a domain that is a part of another (main) domain. For example, if a domain offered an online store as part of their website example.com, it might use the subdomain shop.example.com . Overview The Domain Name System (DNS) has a tree structure or hierarchy, which includes nodes on the tree being a domain name. A subdomain is a domain that is part of a larger domain. Each label may contain from 1 to 63 octets. The full domain name may not exceed a total length of 253 ASCII characters in its textual representation.RFC 1035, ''Domain names--Implementation and specification'', P. Mockapetris (Nov 1987) Subdomains are defined by editing the DNS zone file pertaining to the parent domain. However, there is an ongoing debate over the use of the term "subdomain" when referring to names which map to the Address record A (host) and various other types of zone records which may map to any public IP address destination and any typ ...

OpenSUSE
openSUSE () is a free and open source RPM-based Linux distribution developed by the openSUSE project. The initial release of the community project was a beta version of SUSE Linux 10.0. Additionally the project creates a variety of tools, such as YaST, Open Build Service, openQA, Snapper, Machinery, Portus, KIWI and OSEM. Product history In the past, the SUSE Linux company had focused on releasing the SUSE Linux Personal and SUSE Linux Professional box sets which included extensive printed documentation that was available for sale in retail stores. The company's ability to sell an open source product was largely due to the closed-source development process used. Although SUSE Linux had always been free software product licensed with the GNU General Public License (GNU GPL), it was only freely possible to retrieve the source code of the next release 2 months after it was ready for purchase. SUSE Linux' strategy was to create a technically superior Linux distribution with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SUSE Linux Enterprise Server
SUSE Linux Enterprise (often abbreviated to SLE) is a Linux-based operating system developed by SUSE. It is available in two editions, suffixed with Server (SLES) for servers and mainframes, and Desktop (SLED) for workstations and desktop computers. Its major versions are released at an interval of 3–4 years, while minor versions (called "Service Packs") are released about every 12 months. SUSE Linux Enterprise products receive more intense testing than the upstream openSUSE community product, with the intention that only mature, stable versions of the included components will make it through to the released enterprise product. It is developed from a common code base with other SUSE Linux Enterprise products. IBM's Watson was built on IBM's POWER7 systems using SLES. In March 2018, SUSE Product Manager Jay Kruemcke wrote in SUSE blog that SUSE Linux Enterprise developers have ported it to Raspberry Pi.
