Sysdig is a simple tool for deep system visibility, with native support for containers. It combines features of multiple system administration tools such as the strace, tcpdump, htop, iftop and lsof into a single interface. The novel architecture of the tool means that the performance impact of the tracing on the system is very light, compared to the likes of strace. The sysdig command has an interface similar to strace, while the csysdig command is better suited for interactive used, and has a user interface similar to htop.

If you use Guix System, the kernel Linux has BPF support, and you should launch this tool using the --modern-bpf argument of the sysdig or csysdig commands. The following Bash aliases can be added to your ~/.bash_profile file, for example:

alias sysdig=sudo sysdig --modern-bpf alias cysdig=sudo csysdig --modern-bpf

Netcat is a simple Unix utility which reads and writes data across network connections using TCP or UDP 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.

This package contains the OpenBSD rewrite of netcat, including support for IPv6, proxies, and Unix sockets.

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.

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.

Detox is a program that renames files to make them easier to work with under Unix and related operating systems. Spaces and various other unsafe characters (such as "$") get replaced with "_". ISO 8859-1 (Latin-1) characters can be replaced as well, as can UTF-8 characters.

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

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

The Cactus File Manager (cfm) helps you manage your files visually from a text terminal. It aims to be simple and fast, with key bindings inspired by vi.

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.

pam_uaccess is a PAM module that grants access to devices tagged uaccess in udev for the duration of the users' session, replacing elogind's uaccess feature.

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.

This package provides a utility to flash a new firmware image to a Netgear device. It has been tested on Netgear EX2700, EX6120, EX6150v2, DNG3700v2, R6100, R6220, R7000, D7000, WNR3500, R6400, R6800, R8000, R8500, WNDR3800, but is likely to be compatible with many other Netgear devices.

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.

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.

Utility to convert lsof output to a graph showing FIFO and UNIX interprocess communication.

GNU Alive sends periodic pings to a server, generally to keep a connection alive.

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.

Autojump provides a faster way to navigate your file system, with a "cd command that learns". It works by maintaining a database of the directories you use the most from the command line and allows you to "jump" to frequently used directories by typing only a small pattern.

Neofetch is a command-line system information tool written in Bash. Neofetch displays information about your system next to an image, your OS logo, or any ASCII file of your choice. The main purpose of Neofetch 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.

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

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.

Ktsuss stands for ``Keep the su simple, stupid''. It is a graphical version of su written in C and GTK+ 2, with simplicity in mind.

This package provides udev bindings for Python.

Provides a DHCP and a DHCPv6 client. Additionally, dhcpcd is also an IPv4LL (aka ZeroConf) client. In layperson's terms, dhcpcd runs on your machine and silently configures your computer to work on the attached networks without trouble and mostly without configuration.
