Net::CIDR::Lite merges IPv4 or IPv6 CIDR addresses.

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.

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.

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).

Net::DNS::Resolver::Mock is a subclass of Net::DNS::Resolver, but returns static data from any provided DNS zone file instead of querying the network. It is intended primarily for use in testing.

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.

Librecast is a C library which supports IPv6 multicast networking.

httpstat is a tool to visualize statistics from the curl HTTP client. It acts as a wrapper for curl and prints timing information for each step of the HTTP request (DNS lookup, TCP connection, TLS handshake and so on) in the terminal.

Command line interface for testing internet bandwidth using speedtest.net.

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.

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.

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.

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.

This package provides a daemon that snitches on programs making outbound connections. OpenSnitch is an application-level firewall that gives you granular control over outbound network connections on your system. It monitors application activity and prompts you to allow or deny connections on a per-application basis whenever a new outbound connection is attempted.

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.

The Link Layer Discovery Protocol (LLDP) is an industry standard protocol designed to supplant proprietary Link-Layer protocols such as EDP or CDP. The goal of LLDP is to provide an inter-vendor compatible mechanism to deliver Link-Layer notifications to adjacent network devices. lldpd is an implementation of LLDP. It also supports some proprietary protocols.

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.

The Simple Network Management Protocol (SNMP) is a widely used protocol for monitoring the health and welfare of network equipment (e.g. routers), computer equipment and even devices like UPSs. Net-SNMP is a suite of applications used to implement SNMP v1, SNMP v2c and SNMP v3 using both IPv4 and IPv6.

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

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.

C library implementation of RaptorQ Forward Error Correction for Librecast. RFC6330 (IETF) describes the RaptorQ proposed standard, which LCRQ more-or-less follows. The primary focus has been on building a fast, simple and dependency-free FEC implementation for use with Librecast, and not on strict standards compliance. The code does, however, fairly closely follow the RFC.

OpenRDAP is a command line client for the Registration Data Access Protocol. RDAP is modern a replacement for WHOIS, which provides domain name and IP address registration information in JSON format over HTTP.

lcsync is a tool to sync files over IPv6 multicast or the local filesystem. It splits the file into blocks, hashes them, and compares them in order to efficiently transfer a minimal amount of data.
