up2date, also known as the Red Hat Update Agent, is a tool used by older versions of Red Hat Enterprise Linux, CentOS and Fedora Core that downloads and installs new software and upgrades the operating system. It functions as a front-end to the RPM Package Manager and adds advanced features such as automatic dependency resolution. The file /etc/sysconfig/rhn/sources specifies where up2date will search for packages.
By default, Red Hat Enterprise Linux's up2date retrieves packages from a Red Hat Network (RHN) server, though users can add directories full of packages or even Debian and yum repositories if they wish.
up2date on Fedora Core defaults to retrieving packages from yum repositories. Again, other sources can be added (apart from RHN, which is Red Hat Enterprise Linux Specific). As of Fedora Core 5 and Red Hat Enterprise Linux 5, up2date is no longer shipped with the distribution; yum is used instead.
CentOS's up2date downloads packages from yum repositories on the CentOS Mirror Network Archived 2006-05-28 at the Wayback Machine .
A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems ranging from embedded devices and personal computers to powerful supercomputers.
A package manager or package-management system is a collection of software tools that automates the process of installing, upgrading, configuring, and removing computer programs for a computer in a consistent manner.
The Yellowdog Updater Modified (YUM) is a free and open-source command-line package-management utility for computers running the Linux operating system using the RPM Package Manager. Though YUM has a command-line interface, several other tools provide graphical user interfaces to YUM functionality.
Red Hat Network is a family of systems-management services operated by Red Hat. RHN makes updates, patches, and bug fixes of packages included within Red Hat Linux and Red Hat Enterprise Linux available to subscribers. Other available features include the deployment of custom content to, and the provisioning, configuration, reporting, monitoring of client systems.
Red Hat Enterprise Linux (RHEL) is a commercial Linux distribution developed by Red Hat for the commercial market. Red Hat Enterprise Linux is released in server versions for x86-64, Power ISA, ARM64, and IBM Z and a desktop version for x86-64. Fedora Linux and CentOS Stream serve as its upstream sources. All of Red Hat's official support and training, together with the Red Hat Certification Program, focuses on the Red Hat Enterprise Linux platform.
CentOS is a discontinued Linux distribution that provided a free and open-source community-supported computing platform, functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). In January 2014, CentOS announced the official joining with Red Hat while staying independent from RHEL, under a new CentOS governing board.
Planet CCRMA is a collection of Red Hat packages to help set up and optimize a Red Hat-based workstation for audio work.
Technical variations of Linux distributions include support for different hardware devices and systems or software package configurations. Organizational differences may be motivated by historical reasons. Other criteria include security, including how quickly security upgrades are available; ease of package management; and number of packages available.
Red Hat Enterprise Linux derivatives are Linux distributions that are based on the source code of Red Hat Enterprise Linux (RHEL).
BioLinux is a term used in a variety of projects involved in making access to bioinformatics software on a Linux platform easier using one or more of the following methods:
Fedora Linux is a Linux distribution developed by the Fedora Project. It was originally developed in 2003 as a continuation of the Red Hat Linux project. It contains software distributed under various free and open-source licenses and aims to be on the leading edge of open-source technologies. It is now the upstream source for CentOS Stream and Red Hat Enterprise Linux.
RepoForge is a repository of software packages for Red Hat Enterprise Linux and derivatives such as CentOS and Scientific Linux. It provides many packages in the rpm package format to these distributions. RepoForge also has many RPM packages available for old distributions like Red Hat 6 and earlier, after they are no longer supported by their vendors. Their repository can be accessed via package management products like apt-get and yum; up2date does not work any more due to expired SSL keys.
RPM Package Manager (RPM) is a free and open-source package management system. The name RPM refers to the .rpm file format and the package manager program itself. RPM was intended primarily for Linux distributions; the file format is the baseline package format of the Linux Standard Base.
Fedora Linux is a popular Linux distribution developed by the Fedora Project. Fedora attempts to maintain a six-month release schedule, offering new versions in May and November, although some releases have experienced minor delays.
A delta update is a software update that requires the user to download only those parts of the software's code that are new, or have been changed from their previous state, in contrast to having to download the entire program. The use of delta updates can save significant amounts of time and computing bandwidth. The name "delta" derives from the mathematical science use of the Greek letter delta, Δ or δ to denote change.
Dracut is a set of tools that provide enhanced functionality for automating the Linux boot process. The tool named dracut is used to create a Linux boot image (initramfs) by copying tools and files from an installed system and combining it with the Dracut framework, which is usually found in /usr/lib/dracut/modules.d.
DNF or Dandified YUM is the next-generation version of the Yellowdog Updater, Modified (yum), a package manager for .rpm-based Linux distributions. DNF was introduced in Fedora 18 in 2013; it has been the default package manager since Fedora 22 in 2015, Red Hat Enterprise Linux 8, and OpenMandriva, and is also an alternative package manager for Mageia.
firewalld is a firewall management tool for Linux operating systems. It provides firewall features by acting as a front-end for the Linux kernel's netfilter framework. firewalld's current default backend is nftables. Prior to v0.6.0, iptables was the default backend. Through its abstractions, firewalld acts as an alternative to nft and iptables command line programs. The name firewalld adheres to the Unix convention of naming system daemons by appending the letter "d".
AlmaLinux is a free and open source Linux distribution, developed by the AlmaLinux OS Foundation, a 501(c) organization, to provide a community-supported, production-grade enterprise operating system that is binary-compatible with Red Hat Enterprise Linux (RHEL). The name of the distribution comes from the word "alma", meaning "soul" in Spanish and other Latin languages. It was chosen to be a homage to the Linux community.
