GNU acct provides a means for system administrators to determine system usage patterns. It provides information on, for example, connections, programs executed, and system resources used.

Ansible aims to be a radically simple IT automation system. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible facilitates complex changes like zero-downtime rolling updates with load balancers. This package is the core of Ansible, which provides the following commands:

• ansible

• ansible-config

• ansible-connection

• ansible-console

• ansible-doc

• ansible-galaxy

• ansible-inventory

• ansible-playbook

• ansible-pull

• ansible-test

• ansible-vault

This package provides a simple, configurable system information tool.

Fasd (pronounced similar to "fast") is a command-line productivity booster. Fasd offers quick access to files and directories for POSIX shells. It is inspired by tools like autojump, z, and v. Fasd keeps track of files and directories you have accessed so that you can quickly reference them in the command line.

Fastfetch is a tool for fetching system information and displaying it in a stylized way. Fastfetch displays this information next to a logo of the system distribution, akin to many similar tools.

ISC's Dynamic Host Configuration Protocol (DHCP) distribution provides a reference implementation of all aspects of DHCP, through a suite of DHCP tools: server, client, and relay agent.

This software is end-of-life! ISC does not intend to issue any further maintenance releases.

Stress is a tool that imposes a configurable amount of CPU, memory, I/O, or disk stress on a POSIX-compliant operating system and reports any errors it detects.

Stress is not a benchmark. It is a tool used by system administrators to evaluate how well their systems will scale, by kernel programmers to evaluate perceived performance characteristics, and by systems programmers to expose the classes of bugs which only or more frequently manifest themselves when the system is under heavy load.

Spindle is a tool for improving the performance of dynamic library and Python loading in HPC environments.

Rdfind is a command line tool that finds duplicate files based on their content instead of their file names. It is useful for compressing backup directories or just finding duplicate files.

The GNU Shepherd is a daemon-managing daemon, meaning that it supervises the execution of system services, replacing similar functionality found in typical init systems. It provides dependency-handling through a convenient interface and is based on GNU Guile.

Ansible aims to be a radically simple IT automation system. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible facilitates complex changes like zero-downtime rolling updates with load balancers. This package provides a curated set of community-maintained Ansible collections, which contain playbooks, roles, modules and plugins that extend Ansible.

Shadow provides a number of authentication-related tools, including: login, passwd, su, groupadd, and useradd.

Tcptrack is a sniffer which displays information about TCP connections it sees on a network interface. This is a fork of Steve Benson’s tcptrack.

Hosts is a command line program for managing /etc/hosts entries. On Guix System, /etc/hosts is managed from the system configuration; hosts only works when using the Guix package manager on a foreign distro. hosts works with existing hosts files and entries, providing commands to add, remove, comment, and search.

This package provides a system fetch tool, similar to neofetch, fastfetch, etc. It is lightweight and has a focus on performance. It can be used as a greeter by starting it from ~/.bashrc for example.

This project aims to provide an extension to the Shepherd, retraining it as a swineherd, a manager of crude system containers. It does this by providing a Shepherd service swineherd that talks to the Shepherd process to create Guix System containers as Shepherd services. It also comes with an optional HTTP API server.

The libcap-ng library is intended to make programming with POSIX capabilities easier than the traditional libcap library. It includes utilities that can analyse all currently running applications and print out any capabilities and whether or not it has an open ended bounding set. The included utilities are designed to let admins and developers spot apps from various ways that may be running with too much privilege.

The smartmontools package contains utility programs to control and monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (S.M.A.R.T.) built into most modern ATA and SCSI hard disks. In many cases, these utilities will provide advanced warning of disk degradation and failure.

nq can create very lightweight job queue systems which require no setup, maintenance, supervision, or any long-running processes.

Nmon is yet another system monitor useful in systems administration, debugging, tuning, and benchmarking.

The configurable ncurses interface displays all the classic resource usage statistics (CPU, memory, network, disk, ...) as real-time graphs or numbers. It can also list the processes responsible in a top-like table.

A less common nmon feature is its ability to create highly detailed log files in CSV format. These can be imported into spreadsheets or fed straight into an RRD using rrdtool for further analysis, or to create colourful graphs.

UDPcast is a file transfer tool that can send data simultaneously to many destinations on a LAN. This can for instance be used to install entire classrooms of PC's at once. The advantage of UDPcast over using other methods (nfs, ftp, whatever) is that UDPcast uses UDP's multicast abilities: it won't take longer to install 15 machines than it would to install just 2.

This package provides the hcloud binary, a command-line interface for interacting with the Hetzner Cloud service.

This package provides tools to manage clients of the Logitech Unifying Receiver.

This package provides the /etc/services, /etc/protocols, and /etc/rpc files, which contain information about the IANA-assigned port, protocol, and ONC RPC numbers.
