Libnfsidmap is a library holding multiple methods of mapping names to ids and visa versa, mainly for NFSv4. It provides an extensible array of mapping functions, currently consisting of two choices: the default nsswitch and the experimental umich_ldap.

ddate displays the Discordian date and holidays of a given date. The Discordian calendar was made popular by the "Illuminatus!" trilogy by Robert Shea and Robert Anton Wilson.

nfacct is the command line tool to create/retrieve/delete accounting objects

1. listing the objects of the nfacct table in plain text/XML

2. atomically get and reset objects of the nfacct table

3. adding new objects to the nfacct table

4. deleting objects from the nfacct table

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

The libseccomp library provides an easy to use, platform independent, interface to the Linux Kernel's syscall filtering mechanism. The libseccomp API is designed to abstract away the underlying BPF based syscall filter language and present a more conventional function-call based filtering interface that should be familiar to, and easily adopted by, application developers.

Dual Function Keys is a plugin for interception-tools that allows one to send arbitrary keycodes when a given key is tapped or held.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

cachefilesd is a userspace daemon that manages the cache data store that is used by network file systems such as AFS and NFS to cache data locally on disk. The content of the cache is persistent over reboots.

ltrace intercepts and records dynamic library calls which are called by an executed process and the signals received by that process. It can also intercept and print the system calls executed by the program.

TLP is a power management tool for Linux. It comes with a default configuration already optimized for battery life. Nevertheless, TLP is customizable to fulfil system requirements. TLP settings are applied every time the power supply source is changed.

This package provides commands to create and check XFS file systems.

This package provides statically-linked e2fsck command taken from the e2fsprogs package. It is meant to be used in initrds.

This package contains Advanced Linux Sound Architecture Use Case Manager configuration of audio input/output names and routing for specific audio hardware.

Util-linux is a diverse collection of Linux kernel utilities. It provides dmesg and includes tools for working with file systems, block devices, UUIDs, TTYs, and many other tools.

A suite of tools for manipulating the metadata of the dm-thin, dm-cache and dm-era device-mapper targets.

cpupower is a set of user-space tools that use the cpufreq feature of the Linux kernel to retrieve and control processor features related to power saving, such as frequency and voltage scaling.

The reform2_lpc module allows for interaction with the NXP LPC11U24 Cortex-M0 MCU system controller in the Reform 2 open hardware laptop. It provides battery status information and is necessary to completely shut down the system when powering it off via userspace.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

Libnftnl is a userspace library providing a low-level netlink programming interface to the in-kernel nf_tables subsystem. The library libnftnl has been previously known as libnftables. This library is currently used by nftables.

This package provides small event loop that wraps the epoll family of APIs.

The tool conntrack provides a full featured interface that is intended to replace the old /proc/net/ip_conntrack interface. Using conntrack, you can view and manage the in-kernel connection tracking state table from userspace. On the other hand, conntrackd covers the specific aspects of stateful firewalls to enable highly available scenarios, and can be used as statistics collector as well.

Since 1.2.0, the conntrack-tools includes the nfct command line utility. This utility only supports the nfnetlink_cttimeout by now. In the long run, we expect that it will replace conntrack by providing a syntax similar to nftables.

IP sets are a framework inside the Linux 2.4.x and 2.6.x kernel which can be administered by the ipset utility. Depending on the type, currently an IP set may store IP addresses, (TCP/UDP) port numbers or IP addresses with MAC addresses in a way which ensures lightning speed when matching an entry against a set.

If you want to

• store multiple IP addresses or port numbers and match against the entire collection using a single iptables rule.

• dynamically update iptables rules against IP addresses or ports without performance penalty.

• express complex IP address and ports based rulesets with a single iptables rule and benefit from the speed of IP sets.

then IP sets may be the proper tool for you.

Utilities for Linux's Ethernet bridging facilities. A bridge is a way to connect two Ethernet segments together in a protocol independent way. Packets are forwarded based on Ethernet address, rather than IP address (like a router). Since forwarding is done at Layer 2, all protocols can go transparently through a bridge.

acpilight is a backward-compatibile replacement for xbacklight that uses the ACPI interface to set the display brightness. On modern laptops acpilight can control both display and keyboard backlight uniformly on either X11, the console or Wayland.
