dnstracer determines where a given Domain Name Server (DNS) gets its information from, and follows the chain of DNS servers back to the servers which know the data.

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

NDisc6 is a collection of tools for IPv6 networking diagnostics. It includes the following programs:

• ndisc6: ICMPv6 Neighbor Discovery tool.

• rdisc6: ICMPv6 Router Discovery tool.

• tcptraceroute6: IPv6 traceroute over TCP.

• traceroute6: IPv6 traceroute over UDP.

• rdnssd: Recursive DNS Servers discovery daemon.

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

Netperf is a benchmark that can be used to measure the performance of many different types of networking. It provides tests for both unidirectional throughput, and end-to-end latency. The environments currently measurable by netperf include: TCP and UDP via BSD Sockets for both IPv4 and IPv6, DLPI, Unix Domain Sockets, SCTP for both IPv4 and IPv6.

Axel tries to accelerate the download process by using multiple connections per file, and can also balance the load between different servers. It tries to be as light as possible, so it might be useful on byte-critical systems. It supports HTTP, HTTPS, FTP and FTPS protocols.

This package provides a tiny HTTP client library in C.

parprouted is a daemon for transparent IP (Layer 3) proxy ARP bridging. Unlike standard bridging, proxy ARP bridging can bridge Ethernet networks behind wireless nodes. Normal layer 2 bridging does not work between wireless nodes because wireless does not know about MAC addresses used in the wired Ethernet networks. This daemon can also be useful for making transparent firewalls.

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

knockd is a port-knock daemon. It listens to all traffic on an ethernet or PPP interface, looking for special "knock" sequences of port-hits (UDP/TCP packets sent to a server port). This port need not be open, since knockd listens at the link-layer level.

librdkafka is a C library implementation of the Apache Kafka protocol, containing both Producer and Consumer support.

SRT is a transport technology that optimizes streaming performance across unpredictable networks, such as the Internet.

pproxy is an asynchronuous proxy server implemented with Python 3 asyncio. Among the supported protocols are HTTP, SOCKS and SSH, and it can use both TCP and UDP as transport mechanisms.

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.

This package provides the commandline utilities nfs4_getfacl and nfs4_setfacl, which are similar to their POSIX equivalents getfacl and setfacl. They fetch and manipulate access control lists for files and directories on NFSv4 mounts.

The Network File System (NFS) was developed to allow machines to mount a disk partition on a remote machine as if it were a local disk. It allows for fast, seamless sharing of files across a network.

Nickle is a programming language based prototyping environment with powerful programming and scripting capabilities. Nickle supports a variety of datatypes, especially arbitrary precision numbers. The programming language vaguely resembles C. Some things in C which do not translate easily are different, some design choices have been made differently, and a very few features are simply missing. Nickle provides the functionality of Unix bc, dc and expr in a different form. It is also an ideal environment for prototyping complex algorithms. Nickle's scripting capabilities make it a replacement for spreadsheets in some applications, and its numeric features complement the limited numeric functionality of text-oriented languages such as AWK and Perl.

Nicotine+ is a graphical client for the Soulseek peer-to-peer file sharing network. It is an attempt to keep Nicotine working with the latest libraries, kill bugs, keep current with the Soulseek protocol, and add some new features that users want and/or need.

Nim (formerly known as Nimrod) is a statically-typed, imperative programming language that tries to give the programmer ultimate power without compromises on runtime efficiency. This means it focuses on compile-time mechanisms in all their various forms.

Node SerialPort is a modular suite of Node.js packages for accessing serial ports. The Guix package node-serialport provides the recommended high-level interface.

Parsers are used to take raw binary data and transform them into usable messages. This package provides Regex, a parser that uses a regular expression to split the incoming text.

This module provides source map support for stack traces in node via the V8 stack trace API. It uses the source-map module to replace the paths and line numbers of source-mapped files with their original paths and line numbers. The output mimics node's stack trace format with the goal of making every compile-to-JS language more of a first-class citizen. Source maps are completely general (not specific to any one language) so you can use source maps with multiple compile-to-JS languages in the same node process.

once is a Node.js module to call a function exactly one time. Subsequent calls will either return the cached previous value or throw an error if desired.

Typescript definition files (*.d.ts) for 'estree'.

Like which(1) unix command. Find the first instance of an executable in the PATH.
