Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ approach.

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.

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.

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

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.

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

Netdiscover is a network address discovery tool developed mainly for wireless networks without a DHCP server. It also works on hub/switched networks. It is based on ARP packets, it will send ARP requests and sniff for replies.

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).

VDE is a set of programs to provide virtual software-defined Ethernet network interface controllers across multiple virtual or physical, local or remote devices. The VDE architecture provides virtual counterparts to hardware components such as switches and cables.

ENet's purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP. The primary feature it provides is optional reliable, in-order delivery of packets. ENet omits certain higher level networking features such as authentication, server discovery, encryption, or other similar tasks that are particularly application specific so that the library remains flexible, portable, and easily embeddable.

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

This package provides a tiny HTTP client library in C.

Iodine tunnels IPv4 data through a DNS server. This can be useful in different situations where internet access is firewalled, but DNS queries are allowed. The bandwidth is asymmetrical, with limited upstream and up to 1 Mbit/s downstream.

This package provides header-only C++ bindings for ØMQ. The header files contain direct mappings of the abstractions provided by the ØMQ C API.

Proxychains-ng is a preloader which hooks calls to sockets in dynamically linked programs and redirects them through one or more SOCKS or HTTP proxies.

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

This package is a fast tunnel proxy that helps you bypass firewalls.

Features:

• TCP & UDP support

• User management API

• TCP Fast Open

• Workers and graceful restart

• Destination IP blacklist

Wireshark is a network protocol analyzer, or packet sniffer, that lets you capture and interactively browse the contents of network frames.

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).

Zyre provides reliable group messaging over local area networks using zeromq. It has these key characteristics:

• Zyre needs no administration or configuration.

• Peers may join and leave the network at any time.

• Peers talk to each other without any central brokers or servers.

• Peers can talk directly to each other.

• Peers can join groups, and then talk to groups.

• Zyre is reliable, and loses no messages even when the network is heavily loaded.

• Zyre is fast and has low latency, requiring no consensus protocols.

• Zyre is designed for WiFi networks, yet also works well on Ethernet networks.

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

NetAddr::IP manages IPv4 and IPv6 addresses and subsets.

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.

fping is a ping-like program which uses ICMP echo requests to determine if a target host is responding.

fping differs from ping in that you can specify any number of targets on the command line, or specify a file containing the lists of targets to ping. Instead of sending to one target until it times out or replies, fping will send out a ping packet and move on to the next target in a round-robin fashion.
