Kea is an open-source DHCP server developed by the Internet Systems Consortium, authors of ISC DHCP, also known as DHCPd. Kea and ISC DHCP are both implementations of the Dynamic Host Configuration Protocol, a set of standards established by the Internet Engineering Task Force (IETF). Kea software is distributed in source code form on GitHub, [3] from various ISC sites, and through a number of operating system packages. [4] [5] [6] [7] [8] Kea is licensed under the Mozilla Public License 2.0. [9]

The Kea distribution includes a DHCPv4 server, a DHCPv6 server, and a Dynamic DNS (DDNS) server. Significant features include: support for IPv6 prefix delegation, host reservations (which may be optionally stored in a separate back end database), Preboot Execution Environment (PXE) boot, client classification, shared networks, and high-availability (failover pairs). Kea can store leases locally in a memfile, or in a PostgreSQL or MySQL database. [10] [11] Kea has a supported API for writing optional extensions, using 'hooks'. [12]

Kea has a graphical management application, called Stork, that integrates an agent running on the Kea server, an exporter to a Prometheus time-series data store, a Grafana template for data visualization, and the Stork web dashboard. Like Kea, Stork is licensed under the MPL 2.0 license. The Stork dashboard provides a simple graphical display for managing one or many Kea servers. Current features include server status, pool utilization, high-availability status, host reservations, and leases per second. Via the integration with Grafana it also provides detailed statistics on DHCP messages over time. Stork was first released in 2014, and features are being added rapidly in monthly releases.

BIND is a suite of software for interacting with the Domain Name System (DNS). Its most prominent component, named, performs both of the main DNS server roles, acting as an authoritative name server for DNS zones and as a recursive resolver in the network. As of 2015, it is the most widely used domain name server software, and is the de facto standard on Unix-like operating systems. Also contained in the suite are various administration tools such as nsupdate and dig, and a DNS resolver interface library.

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.

Lightning Memory-Mapped Database (LMDB) is an embedded transactional database in the form of a key-value store. LMDB is written in C with API bindings for several programming languages. LMDB stores arbitrary key/data pairs as byte arrays, has a range-based search capability, supports multiple data items for a single key and has a special mode for appending records (MDB_APPEND) without checking for consistency. LMDB is not a relational database, it is strictly a key-value store like Berkeley DB and DBM.

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".

Budgie is an independent, free and open-source desktop environment for Linux and other Unix-like operating systems that targets the desktop metaphor. Budgie is developed by the Buddies of Budgie organization, which is composed of a team of contributors from Linux distributions such as Fedora, Debian, and Arch Linux. Its design emphasizes simplicity, minimalism, and elegance, while providing the means to extend or customize the desktop in various ways. Unlike desktop environments like Cinnamon, Budgie does not have a reference platform, and all distributions that ship Budgie are recommended to set defaults that best fit their desired user experience.
