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.

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

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

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

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.

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.

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.

IFStatus is a simple, easy-to-use program for displaying commonly needed/wanted real-time traffic statistics of multiple network interfaces, with a simple and efficient view on the command line. It is intended as a substitute for the PPPStatus and EthStatus projects.

The ngtcp2 project is an effort to implement the RFC9000 (IETF) QUIC protocol.

Dropwatch is an interactive utility for monitoring and recording packets that are dropped by the kernel. It provides the commands dropwatch and dwdump.

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.

Nload is a console application which monitors network traffic and bandwidth usage in real time. It visualizes the in- and outgoing traffic using two graphs, and provides additional info like total amount of transferred data and min/max network usage.

This package provides a command-line client (gandi) to buy, manage, and delete Internet resources from Gandi.net such as domain names, virtual machines, and certificates.

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.

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.

PuTTY is a graphical text terminal client. It supports SSH, telnet, and raw socket connections with good terminal emulation. It can authenticate with public keys and Kerberos single-sign-on. It also includes command-line SFTP and older SCP implementations.

Librecast is a C library which supports IPv6 multicast networking.

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

With this package you can monitor and filter incoming requests for network services. It includes a library which may be used by daemons to transparently check connection attempts against an access control list.

iPerf is a tool to measure achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6). For each test it reports the bandwidth, loss, and other parameters.

This library allows controlling basic functions in SocketCAN from user-space. It requires a kernel built with SocketCAN support.

Restbed is a comprehensive and consistent programming model for building applications that require seamless and secure communication over HTTP.

Axel tries to accelerate the download process by using multiple connections per file, and can also balance the load between different servers. It tries to be as light as possible, so it might be useful on byte-critical systems. It supports HTTP, HTTPS, FTP and FTPS protocols.

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.
