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.

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.

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.

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

ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets. It is also intended to be a teaching tool and presents the subnetting results as easy-to-understand binary values.

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 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.

mtr combines the functionality of the traceroute and ping programs in a single network diagnostic tool. mtr can use several network protocols to detect intermediate routers (or hops) between the local host and a user-specified destination. It then continually measures the response time and packet loss at each hop, and displays the results in real time.

Blueman is a Bluetooth management utility using the Bluez D-Bus backend. It is designed to be easy to use for most common Bluetooth tasks.

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

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.

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.

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

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.

aMule is an eMule-like client for the eD2k and Kademlia peer-to-peer file sharing networks. It includes a graphical user interface (GUI), a daemon allowing you to run a client with no graphical interface, and a Web GUI for remote access. The amulecmd command allows you to control aMule remotely.

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

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).

Quagga is a routing software suite, providing implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPng and BGP-4 for Unix platforms.

The Quagga architecture consists of a core daemon, zebra, which acts as an abstraction layer to the underlying Unix kernel and presents the Zserv API over a Unix or TCP stream to Quagga clients. It is these Zserv clients which typically implement a routing protocol and communicate routing updates to the zebra daemon.

LibNice is a library that implements the Interactive Connectivity Establishment (ICE) standard (RFC 5245 & RFC 8445). It provides a GLib-based library, libnice, as well as GStreamer elements to use it.

Pixiewps implements the pixie-dust attack to brute force the Wi-Fi Protected Setup (WPS) PIN by exploiting the low or non-existing entropy of some access points.

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.

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

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.

RESTinio is a header-only C++14 library that gives you an embedded HTTP/Websocket server. It is based on standalone version of ASIO and targeted primarily for asynchronous processing of HTTP-requests.
