IFStatus is a simple, easy-to-use program for displaying commonly needed/wanted real-time traffic statistics of multiple network interfaces, with a simple and efficient view on the command line. It is intended as a substitute for the PPPStatus and EthStatus projects.

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.

FRRouting (FRR) is an IP routing protocol suite which includes protocol daemons for BGP, IS-IS, LDP, OSPF, PIM, and RIP.

Slurm is a network load monitor. It shows real-time traffic statistics from any network device in any of three ASCII graph formats.

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.

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.

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.

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.

lcagent can send and receive data over multicast and to pipe data between programs on one computer and as many receivers as the multicast network can support simultaneously.

YAZ is a C/C++ library for information retrieval applications using Z39.50, SRU or Solr Web Service protocols for information retrieval. It also offers ZOOM API implementing them.

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.

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.

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.

Ninja is a small build system with a focus on speed. It differs from other build systems in two major respects: it is designed to have its input files generated by a higher-level build system, and it is designed to run builds as fast as possible.

samurai is a ninja-compatible build tool written in C99 with a focus on simplicity, speed, and portability. It is feature-complete and supports most of the same options as ninja. This package provides the command samu. For a ninja command replacement, use the samu-as-ninja-wrapper package.

This package provides the ninja command, implemented as a symbolic link to the samu command of samurai package.

Ninja is a small build system with a focus on speed. It differs from other build systems in two major respects: it is designed to have its input files generated by a higher-level build system, and it is designed to run builds as fast as possible.

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 package provides a streaming parser for the statsd protocol used in node-lynx.

This package is a low-level, fast and lightweight JavaScript library for decoding and encoding protocol buffers, a compact binary format for structured data serialization. Works both in Node and the browser. It supports lazy decoding and detailed customization of the reading/writing code.

Acornjs is a Javascript parser with many options and an architecture supporting plugins.

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 ByteLength, a parser that emits data as a buffer every time a specified number of bytes are received.
