stress-ng stress-tests a computer system by exercising both physical subsystems as operating system kernel interfaces. It can stress the CPU, cache, disk, memory, socket and pipe I/O, scheduling, and much more, in various selectable ways. This can trip hardware issues such as thermal overruns as well as operating system bugs that occur only when a system is being thrashed hard.

You can also measure test throughput rates, which can be useful to observe performance changes across different operating system releases or types of hardware. However, stress-ng is not a benchmark. Use it with caution: some of the tests can make poorly designed hardware run dangerously hot or make the whole system lock up.

Compared to its inspiration, stress, stress-ng offers many additional options such as the number of bogo operations to run, execution metrics, verification of memory and computational operations, and considerably more stress mechanisms.

daemontools is a collection of tools for managing UNIX services.

This package provides a command-line UEFI image editor, including cbfs, create-ffs, fmap, fspinfo, glzma, guid2english, microcode and utk CLI utilities.

Inetutils is a collection of common network programs, such as an ftp client and server, a telnet client and server, an rsh client and server, and hostname.

cbatticon is a lightweight battery icon that displays the status of your battery in the system tray.

This package provides a program that collects various performance measurement data like CPU, memory, disk and network performance numbers.

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.

MASSCAN is an asynchronous TCP port scanner. It can detect open ports, and also complete the TCP connection and interact with the remote application, collecting the information received.

Show graphs for 1 minute, 5 minute, 15 minute load averages on the console.

wpa_supplicant is a WPA Supplicant with support for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE 802.1X/WPA component that is used in the client stations. It implements key negotiation with a WPA Authenticator and it controls the roaming and IEEE 802.11 authentication/association of the WLAN driver.

This package provides the wpa_supplicant daemon and the wpa_cli command.

Lynis is a security auditing tool. It performs an in-depth security scan and runs on the system itself. The primary goal is to test security defenses and provide tips for further system hardening. It will also scan for general system information, vulnerable software packages, and possible configuration issues.

A program that looks for coreutils basic commands (cp, mv, dd, tar, gzip/gunzip, cat, etc.) currently running on your system and displays the percentage of copied data. It can also show estimated time and throughput, and provides a "top-like" mode (monitoring).

jtbl accepts piped JSON data from stdin and outputs a text table representation to stdout.

This package provides a Perl interface (Perl::Rename) as well as a command-line utility (rename) that can rename multiple files at once based on a Perl regular expression.

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 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.

This package provides programs that transfer files using the XMODEM/YMODEM/ZMODEM file transfer protocols.

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.

Dool is a command line tool to monitor many aspects of your system: CPU, Memory, Network, Load Average, etc. It also includes a robust plug-in architecture to allow monitoring other system metrics.

GNU pies is a program that supervises the invocation and execution of other programs. It reads the list of programs to be started from its configuration file, executes them, and then monitors their status, re-executing them as necessary.

libpcap is an interface for user-level packet capture. It provides a portable framework for low-level network monitoring. Applications include network statistics collection, security monitoring, network debugging, etc.

Resource monitor that shows usage and stats for processor, memory, disks, network and processes.

wpa_supplicant is a WPA Supplicant with support for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE 802.1X/WPA component that is used in the client stations. It implements key negotiation with a WPA Authenticator and it controls the roaming and IEEE 802.11 authentication/association of the WLAN driver.

This package provides the wpa_supplicant daemon and the wpa_cli command.

lr is a tool for generating file listings, which includes the best features of ls(1), find(1), stat(1) and du(1).
