RTMPdump is a toolkit for RTMP streams. All forms of RTMP are supported, including rtmp://, rtmpt://, rtmpe://, rtmpte://, and rtmps://.

Command-line interface for LibreSpeed internet bandwidth testing. It functions as a command-line alternative to https://librespeed.org/. It features ping, jitter, download, and upload testing, as well as the ability to test using multiple servers in a single run.

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.

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.

PageKite implements a tunneled reverse proxy which makes it easy to make a service (such as an HTTP or SSH server) on localhost visible to the wider Internet, even behind NAT or restrictive firewalls. A managed front-end relay service is available at https://pagekite.net/, or you can run your own.

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.

uBridge is a simple program to create user-land bridges between various technologies. Currently, bridging between UDP tunnels, Ethernet and TAP interfaces is supported. Packet capture is also supported.

Net::DNS::Resolver::Programmable is a programmable DNS resolver for offline emulation of DNS.

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.

The THC IPv6 Toolkit provides command-line tools and a library for researching IPv6 implementations and deployments. It requires Linux 2.6 or newer and only works on Ethernet network interfaces.

httping measures how long it takes to connect to a web server, send an HTTP(S) request, and receive the reply headers. It is somewhat similar to ping, but can be used even in cases where ICMP traffic is blocked by firewalls or when you want to monitor the response time of the actual web application stack itself.

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.

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.

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.

The dhtnet is a C++ library providing abstractions for interacting with an OpenDHT distributed network.

Zapret2 is a packet manipulator primarily designed to perform various autonomous real-time attacks on DPI systems. Its main objective is to bypass resource blocks or protocol restrictions. However, zapret2's capabilities are not limited to this; its architecture allows for other types of packet manipulation, such as bidirectional (client-server) protocol obfuscation to hide traffic from DPI, among other applications.

The configuration file is read from /etc/zapret2/config.

This package provides a control tool for the B.A.T.M.A.N. mesh networking routing protocol provided by the Linux kernel module batman-adv, for Layer 2.

socat is a relay for bidirectional data transfer between two independent data channels---files, pipes, devices, sockets, etc. It can create "listening" sockets, named pipes, and pseudo terminals.

socat can be used, for instance, as TCP port forwarder, as a shell interface to UNIX sockets, IPv6 relay, for redirecting TCP oriented programs to a serial line, to logically connect serial lines on different computers, or to establish a relatively secure environment (su and chroot) for running client or server shell scripts with network connections.

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.

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.

NZBGet is a binary newsgrabber, which downloads files from Usenet based on information given in nzb files. NZBGet can be used in standalone and in server/client modes. In standalone mode, you pass NZBGet nzb files as command-line parameters and it downloads them and exits. NZBGet also contains a Web interface. Its server can be controlled through remote procedure calls (RPCs).

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.

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.

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