IO::Socket::INET6 is an interface for AF_INET/AF_INET6 domain sockets in Perl.

Spiped (pronounced "ess-pipe-dee") is a utility for creating symmetrically encrypted and authenticated pipes between socket addresses, so that one may connect to one address (e.g., a UNIX socket on localhost) and transparently have a connection established to another address (e.g., a UNIX socket on a different system). This is similar to 'ssh -L' functionality, but does not use SSH and requires a pre-shared symmetric key.

OpenDHT provides an easy to use distributed in-memory data store. Every node in the network can read and write values to the store. Values are distributed over the network, with redundancy. It includes the following features:

• Lightweight and scalable, designed for large networks and small devices;

• High resilience to network disruption;

• Public key cryptography layer providing optional data signature and encryption (using GnuTLS);

• IPv4 and IPv6 support;

• Clean and powerful C++14 map API;

• Bindings for C, Rust & Python 3;

• REST API with an optional HTTP client and server with push notification support.

The following tools are also included:

dhtnode

A command line tool to run a DHT node and perform operations supported by the library (get, put, etc.) with text values.

dhtchat

A very simple IM client working over the DHT.

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.

Reaver performs a brute force attack against an access point's Wi-Fi Protected Setup (WPS) PIN. Once the PIN is found, the WPA passphrase can be recovered and the AP's wireless settings can be reconfigured.

Net::Bonjour is a set of modules that allow one to discover local services via multicast DNS (mDNS) or enterprise services via traditional DNS. This method of service discovery has been branded as Bonjour by Apple Computer.

Bandwidth Monitor NG is a small and simple console based live network and disk I/O bandwidth monitor.

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.

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

ethtool can be used to query and change settings such as speed, auto-negotiation and checksum offload on many network devices, especially Ethernet devices.

Phantomsocks is an Internet censorship circumvention tool based on the desync technique, which was introduced in the 2017 paper Your State is Not Mine: A Closer Look at Evading Stateful Internet Censorship.

Further information on the usage could be found on the Wikibooks page Phantomsocks.

Libnet provides a fairly portable framework for network packet construction and injection. It features portable packet creation interfaces at the IP layer and link layer, as well as a host of supplementary functionality. Using libnet, quick and simple packet assembly applications can be whipped up with little effort.

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

sslh is a network protocol demultiplexer. It acts like a switchboard, accepting connections from clients on one port and forwarding them to different servers based on the contents of the first received data packet. Detection of common protocols like HTTP(S), SSL, SSH, OpenVPN, tinc, and XMPP is already implemented, but any other protocol that matches a regular expression can be added. sslh's name comes from its original application of serving both SSH and HTTPS on port 443, allowing SSH connections from inside corporate firewalls that block port 22.

NNG project is a rewrite of the scalability protocols library known as libnanomsg, and adds significant new capabilities, while retaining compatibility with the original. It is a lightweight, broker-less library, offering a simple API to solve common recurring messaging problems, such as publish/subscribe, RPC-style request/reply, or service discovery.

This package provides a tiny HTTP client library in C.

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

Tool to send a magic packet to wake another host on the network. This must be enabled on the target host, usually in the BIOS.

This library provides methods for using the stream control transmission protocol (SCTP) in a Go application.

Small tool to capture packets from WLAN devices. After capturing, upload the "uncleaned" cap to https://wpa-sec.stanev.org/?submit to see if the access point or the client is vulnerable to a dictionary attack. Convert the cap file to hccapx format and/or to WPA-PMKID-PBKDF2 hashline (16800) with hcxpcaptool from the hcxtools package and check if the WLAN key or the master key was transmitted unencrypted.

Yggdrasil is an early-stage implementation of a fully end-to-end encrypted IPv6 network. It is lightweight, self-arranging, supported on multiple platforms and allows pretty much any IPv6-capable application to communicate securely with other Yggdrasil nodes. Yggdrasil does not require you to have IPv6 Internet connectivity - it also works over IPv4.

Net::DNS is the Perl Interface to the Domain Name System.

Open vSwitch is a multilayer virtual switch. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, IPFIX, RSPAN, CLI, LACP, 802.1ag).

BIRD is an Internet routing daemon with full support for all the major routing protocols. It allows redistribution between protocols with a powerful route filtering syntax and an easy-to-use configuration interface.
