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

Btop++ provides unified monitoring of CPU, memory, network and processes.

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.

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.

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.

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

dfc (df color) is a modern version of df. It uses colors, draws pretty graphs and can export its output to different formats.

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

Tcpdump is a command-line tool to analyze network traffic passing through the network interface controller.

Nmap ("Network Mapper") is a network discovery and security auditing tool. It is also useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. It also provides an advanced netcat implementation (ncat), a utility for comparing scan results (ndiff), and a packet generation and response analysis tool (nping).

hungrycat prints the contents of a file to standard output, while simultaneously freeing the disk space it occupied. It is useful if you need to process a large file, don't have enough space to store both the input and output files, and don't need the input file afterwards. While similar in principle to running cat immediately followed by rm, hungrycat actually frees blocks as soon as they are printed instead of after the entire file has been read, which is often too late.

The Ansible roles provided by that can be used to manage Debian or Ubuntu hosts. In addition, a default set of Ansible playbooks can be used to apply the provided roles in a controlled way, using Ansible inventory groups.

The roles are written with a high customization in mind, which can be done using Ansible inventory. This way the role and playbook code can be shared between multiple environments, with different configuration in to each one.

Services can be managed on a single host, or spread between multiple hosts. DebOps provides support for different SQL and NoSQL databases, web servers, programming languages and specialized applications useful in a data center environment or in a cluster. The project can also be used to deploy virtualization environments using KVM/libvirt, Docker or LXC technologies to manage virtual machines and/or containers.

Dmidecode reports information about your system's hardware as described in your system BIOS according to the SMBIOS/DMI standard. This typically includes system manufacturer, model name, serial number, BIOS version, asset tag as well as a lot of other details of varying level of interest and reliability depending on the manufacturer. This will often include usage status for the CPU sockets, expansion slots (e.g. AGP, PCI, ISA) and memory module slots, and the list of I/O ports (e.g. serial, parallel, USB).

This is htop, an interactive process viewer. It is a text-mode application (for console or X terminals) and requires ncurses.

The Linux Thermal Daemon helps monitor and control temperature on systems running the Linux kernel.

Sudo (su "do") allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.

ngrep is like GNU grep applied to the network layer. It's a PCAP-based tool that allows you to specify an extended regular or hexadecimal expression to match against data payloads of packets. It understands many kinds of protocols, including IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw, across a wide variety of interface types, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.

This package provides a graphical console greeter for greetd. It doesn't need a Wayland compositor to be used.

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.

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.

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 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.

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.
