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.

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

HyFetch is a command-line system information tool fork of neofetch. HyFetch displays information about your system next to your OS logo in ASCII representation. The ASCII representation is then colored in the pattern of the pride flag of your choice. The main purpose of HyFetch is to be used in screenshots to show other users what operating system or distribution you are running, what theme or icon set you are using, etc.

vmtouch is a tool for learning about and controlling the file system cache of unix and unix-like systems.

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.

Shepherd-run is a script which assists in creating one-off shepherd services from the command line. It is meant to partially fill the void left by systemd-run, since GNU Guix uses GNU Shepherd as its system service manager.

The Router Advertisement Daemon (radvd) is run on systems acting as IPv6 routers. It sends Router Advertisement messages specified by RFC 2461 periodically and when requested by a node sending a Router Solicitation message. These messages are required for IPv6 stateless autoconfiguration.

hostapd is a user-space daemon for WiFi access points and authentication servers. It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP Authenticators, RADIUS client, EAP server, and RADIUS authentication server.

The ACPICA project provides an OS-independent reference implementation of the ACPI specification. ACPICA code contains those portions of ACPI meant to be directly integrated into the host OS as a kernel-resident subsystem, and a small set of tools to assist in developing and debugging ACPI tables.

This package contains only the user-space tools needed for ACPI table development, not the kernel implementation of ACPI.

This package provides udev bindings for Python.

pam-hooks is a tiny PAM module enabling the execution of hook scripts when a PAM session is opened or closed. The typical use case is the need of doing some per-user set-up when a user logs via a PAM-aware login mechanism and/or the need of doing some per-user clean-up when the user logs out.

Btop++ provides unified monitoring of CPU, memory, 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.

Netcat is a featured networking utility which reads and writes data across network connections, using the TCP/IP protocol. It is designed to be a reliable "back-end" tool that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities.

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.

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.

sedsed can debug, indent, tokenize and HTMLize your sed script.

In debug mode, it reads your script and adds extra commands to it. When executed you can see the data flow between the commands, revealing all the magic sed performs on its internal buffers.

In indent mode, your script is reformatted with standard spacing.

In tokenize mode, you can see the elements of every command you use.

In HTMLize mode, your script is converted to a beautiful colored HTML file, with all the commands and parameters identified for your viewing pleasure.

With sedsed you can master any sed script. No more secrets, no more hidden buffers.

Cpulimit limits the CPU usage of a process. It does not change the nice value or other scheduling priority settings, but the real CPU usage, and is able to adapt itself dynamically to the overall system load. Children processes and threads of the specified process may optionally share the same limits.

This package provides an on demand system DBus service. It allows callers to configure network authentication and domain membership in a standard way. Realmd discovers information about the domain or realm automatically and does not require complicated configuration in order to join a domain or realm. Dbus system service that manages discovery and enrollment in realms/domains like Active Directory or IPA.

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

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.

Small console getty that is started on the Linux text console, asks for a login name and then transfers over to login. It is extended to allow automatic login and starting any app.

This package provides a graphical disk usage analyzer in text mode.

Iftop does for network usage what top does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts.
