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.

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.

This package provides a PAM module that hands over your login password to gpg-agent. This can be useful if you are using a GnuPG-based password manager like pass.

Tpacpi-bat is a command-line interface to control battery charging on Lenovo ThinkPad models released after 2011, starting with the xx20 series. It can query and set the thresholds at which one or both batteries will start and stop charging, inhibit charging batteries for a set period of time, or force them to discharge when they otherwise would not.

This tool merely exposes ACPI calls provided by the acpi_call Linux kernel module provided by the acpi-call-linux-module package, which must be installed and loaded separately. Only the original vendor firmware is supported.

Headers of the Linux-Libre kernel.

PRoot is a user-space implementation of chroot, mount --bind, and binfmt_misc. This means that users don't need any privileges or setup to do things like using an arbitrary directory as the new root file system, making files accessible somewhere else in the file system hierarchy, or executing programs built for another CPU architecture transparently through QEMU user-mode. Also, developers can use PRoot as a generic process instrumentation engine thanks to its extension mechanism. Technically PRoot relies on ptrace, an unprivileged system-call available in the kernel Linux.

This package provides the kexec program and ancillary utilities. Using kexec, it is possible to boot directly into a new kernel from the context of an already-running kernel, bypassing the normal system boot process.

LVM2 is the logical volume management tool set for Linux-based systems. This package includes the user-space libraries and tools, including the device mapper. Kernel components are part of Linux-libre.

A *Free* project to implement OSF's RFC 86.0. Pluggable authentication modules are small shared object files that can be used through the PAM API to perform tasks, like authenticating a user at login. Local and dynamic reconfiguration are its key features.

libnvme provides type definitions for NVMe specification structures, enumerations, and bit fields, helper functions to construct, dispatch, and decode commands and payloads, and utilities to connect, scan, and manage nvme devices on a Linux system.

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.

EROFS is a compressed, read-only file system optimized for resource-scarce devices. This package provides user-space tools for creating EROFS file systems.

Prevents shock damage to the internal spinning hard drive(s) of some HP and Dell laptops. When sudden movement is detected, all input/output operations on the drive are suspended and its heads are parked on the ramp, where they are less likely to cause damage to the spinning disc. Requires a drive that supports the ATA/ATAPI-7 IDLE IMMEDIATE command with unload feature, and a laptop with an accelerometer. It has no effect on SSDs.

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.

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 Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux-based operating system.

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

The bbswitch module provides a way to toggle the Nvidia graphics card on Optimus laptops.

The inotify-tools packages provides a C library and command-line tools to use Linux' inotify mechanism, which allows file accesses to be monitored.

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.

The inih (INI Not Invented Here) library is a simple .INI file parser written in C. It's only a couple of pages of code, and it was designed to be small and simple, so it's good for embedded systems. It's also more or less compatible with Python's ConfigParser style of .INI files, including RFC 822-style multi-line syntax and name: value entries.

bpftool allows for inspection and simple modification of BPF objects on the system.

iw is a new nl80211 based CLI configuration utility for wireless devices. It replaces iwconfig, which is deprecated.

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