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.

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

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-krb5 is a Kerberos PAM module for either MIT Kerberos or Heimdal. It supports ticket refreshing by screen savers, configurable authorization handling, authentication of non-local accounts for network services, password changing, and password expiration, as well as all the standard expected PAM features. It works correctly with OpenSSH, even with ChallengeResponseAuthentication and PrivilegeSeparation enabled, and supports extensive configuration either by PAM options or in krb5.conf or both. PKINIT is supported with recent versions of both MIT Kerberos and Heimdal and FAST is supported with recent MIT Kerberos.

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.

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.

This package provides a command line tool that can give numerous reports on memory usage on GNU/Linux systems.

The smartmontools package contains utility programs to control and monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (S.M.A.R.T.) built into most modern ATA and SCSI hard disks. In many cases, these utilities will provide advanced warning of disk degradation and failure.

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.

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.

daemontools is a collection of tools for managing UNIX services.

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.

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.

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.

Tcptrack is a sniffer which displays information about TCP connections it sees on a network interface. This is a fork of Steve Benson’s tcptrack.

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.

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.

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.

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

This package provides an editor for the Novena EEPROM. Novena boards contain a device-dependent descriptive EEPROM that defines various parameters such as serial number, MAC address, and featureset. This program allows you to view and manipulate this EEPROM list.

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

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

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.
