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.

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.

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.

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.

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

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

Net::Patricia does IP address lookups quickly in Perl.

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.

librdkafka is a C library implementation of the Apache Kafka protocol, containing both Producer and Consumer support.

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.

Arp-scan is a tool that uses ARP to discover and fingerprint IP hosts on the local network.

Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages.

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.

NetHogs is a small 'net top' tool for Linux. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process.

NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to identify programs that have gone wild and are suddenly taking up your bandwidth.

pproxy is an asynchronuous proxy server implemented with Python 3 asyncio. Among the supported protocols are HTTP, SOCKS and SSH, and it can use both TCP and UDP as transport mechanisms.

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

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

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.

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.

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.

This package contains a small set of tools to capture and convert packets from wireless devices for use with hashcat or John the Ripper.

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

nm-tray is a network connection management tool (NetworkManager front-end) with an information icon residing in the system tray. Unlike nm-applet, which is part of GNOME, this application is desktop-unaware.

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.
