Sipcalc is an advanced command-line IP subnet calculator. It can take multiple forms of input (IPv4/IPv6/interface/hostname) and output a multitude of information about a given subnet.

Features include:

• IPv4

  • Retrieving of address information from interfaces.

  • Classfull and CIDR output.

  • Multiple address and netmask input and output formats (dotted quad, hex, number of bits).

  • Output of broadcast address, network class, Cisco wildcard, hosts/range, network range.

  • The ability to split a network based on a smaller netmask, now also with recursive runs on the generated subnets. (also IPv6)

• IPv6

  • Compressed and expanded input and output addresses.

  • Standard IPv6 network output.

  • v4 in v6 output.

  • Reverse DNS address generation.

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.

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.

The Neighbor Discovery Protocol Proxy Daemon (ndppd) proxies some IPv6 NDP messages between interfaces to allow IPv6 routing between machines that are in the same network but not on the same local link. It currently only supports Neighbor Solicitation and Neighbor Advertisement messages.

Prips can be used to print all of the IP addresses in a given range. This allows the enhancement of tools only work on one host at a time (e.g. whois).

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.

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.

AIDE (Advanced Intrusion Detection Environment) is a file and directory integrity checker. It creates a database from the regular expression rules that it finds from its configuration files. Once this database is initialized it can be used to verify the integrity of the files. It has several message digest algorithms that are used to check the integrity of files. All of the usual file attributes can be checked for inconsistencies.

di is a disk information utility, displaying everything that your df command does and more. It features the ability to display your disk usage in whatever format you prefer. It is designed to be highly portable and produce uniform output across heterogeneous networks.

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.

greetd is a minimal and flexible login manager daemon that makes no assumptions about what you want to launch.

If you can run it from your shell in a TTY, greetd can start it.

If it can be taught to speak a simple JSON-based IPC protocol, then it can be a greeter.

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.

daemontools is a collection of tools for managing UNIX services.

This package provides udev bindings for Python.

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

GNU Rot[t]log is a program for managing log files. It is used to automatically rotate out log files when they have reached a given size or according to a given schedule. It can also be used to automatically compress and archive such logs. Rot[t]log will mail reports of its activity to the system administrator.

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.

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.

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

A daemon that monitors directories for events, such as creating, deleting or modifying files. It can monitor different sets of directories for different events. When an event is detected, direvent calls a specified external program with information about the event, such as the location within the file system where it occurred. Thus, "direvent" provides an easy way to react immediately if given files undergo changes, for example, to track changes in important system configuration files.

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).

Doas is a minimal replacement for the venerable sudo. It was initially written by Ted Unangst of the OpenBSD project to provide 95% of the features of sudo with a fraction of the codebase.

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.
