This package provides a modern, but Linux-specific implementation of the traceroute command that can be used to follow the route taken by packets on an IP network on their way to a given host. It utilizes the IP protocol's time to live (TTL) field and attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along the path to the host. Compared to other implementations, this traceroute command allows some traces for unprivileged users.

nm-tray is a network connection management tool (NetworkManager front-end) with an information icon residing in the system tray. Unlike nm-applet, which is part of GNOME, this application is desktop-unaware.

This module provides several IP address validation subroutines that both validate and untaint their input. This includes both basic validation (is_ipv4() and is_ipv6()) and special cases like checking whether an address belongs to a specific network or whether an address is public or private (reserved).

This package provides CAN utilities in the following areas:

• Basic tools to display, record, generate and replay CAN traffic

• CAN access via IP sockets

• CAN in-kernel gateway configuration

• CAN bus measurement and testing

• ISO-TP (ISO15765-2:2016 - this means messages with a body larger than eight bytes) tools

• Log file converters

• Serial Line Discipline configuration for slcan driver

LibCamera is a complex camera support library for GNU+Linux, Android, and ChromeOS.

This package provides a control tool for the B.A.T.M.A.N. mesh networking routing protocol provided by the Linux kernel module batman-adv, for Layer 2.

With this package you can monitor and filter incoming requests for network services. It includes a library which may be used by daemons to transparently check connection attempts against an access control list.

Danga::Socket is an abstract base class for objects backed by a socket which provides the basic framework for event-driven asynchronous IO, designed to be fast. Danga::Socket is both a base class for objects, and an event loop.

Hashcash is a proof-of-work algorithm, which has been used as a denial-of-service countermeasure technique in a number of systems.

A hashcash stamp constitutes a proof-of-work which takes a parametrizable amount of work to compute for the sender. The recipient can verify received hashcash stamps efficiently.

This package contains a command-line tool for computing and verifying hashcash stamps.

yggtray is an Yggdrasil tray and control panel. It allows the user to configure, run and control the Yggdrasil daemon.

This package provides a C implementation of a lightweight application-protocol for devices that are constrained their resources such as computing power, RF range, memory, bandwidth, or network packet sizes. This protocol, CoAP, is standardized by the IETF as RFC 7252.

The lksctp-tools project provides a user-space library for SCTP (libsctp) and C language header files (netinet/sctp.h) for accessing SCTP-specific APIs not provided by the standard sockets. It also includes some SCTP-related helper utilities.

UsrSCTP is a portable SCTP userland stack. SCTP is a message oriented, reliable transport protocol with direct support for multihoming that runs on top of IP or UDP, and supports both v4 and v6 versions.

Quagga is a routing software suite, providing implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPng and BGP-4 for Unix platforms.

The Quagga architecture consists of a core daemon, zebra, which acts as an abstraction layer to the underlying Unix kernel and presents the Zserv API over a Unix or TCP stream to Quagga clients. It is these Zserv clients which typically implement a routing protocol and communicate routing updates to the zebra daemon.

This package provides a tiny HTTP client library in C.

The THC IPv6 Toolkit provides command-line tools and a library for researching IPv6 implementations and deployments. It requires Linux 2.6 or newer and only works on Ethernet network interfaces.

wireproxy is a completely userspace application that connects to a wireguard peer, and exposes a socks5/http proxy or tunnels on the machine.

The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialized messaging middle-ware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.

NetHogs is a small 'net top' tool for Linux. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process.

NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to identify programs that have gone wild and are suddenly taking up your bandwidth.

Aircrack-ng is a complete suite of tools to assess WiFi network security. It focuses on different areas of WiFi security: monitoring, attacking, testing, and cracking. All tools are command-line driven, which allows for heavy scripting.

Command-line interface for LibreSpeed internet bandwidth testing. It functions as a command-line alternative to https://librespeed.org/. It features ping, jitter, download, and upload testing, as well as the ability to test using multiple servers in a single run.

Nebula is a peer-to-peer networking tool based on the Noise Protocol Framework. It is not a fully decentralized network, but instead uses central discovery nodes and a certificate authority to facilitate direct, encrypted peer-to-peer connections from behind most firewalls and NAT layers.

mbuffer is a tool for buffering data streams with a large set of features:

• direct support for TCP based network targets (IPv4 and IPv6)

• ability to send to multiple targets in parallel (distribution mode)

• support for multiple volumes

• I/O rate limitation

• high/low watermark based restart criteria

• configurable buffer size

• on the fly MD5 hash calculation

• highly efficient, multi-threaded implementation

libnatpmp is a portable and asynchronous implementation of the Network Address Translation - Port Mapping Protocol (NAT-PMP) written in the C programming language.
