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

sslh is a network protocol demultiplexer. It acts like a switchboard, accepting connections from clients on one port and forwarding them to different servers based on the contents of the first received data packet. Detection of common protocols like HTTP(S), SSL, SSH, OpenVPN, tinc, and XMPP is already implemented, but any other protocol that matches a regular expression can be added. sslh's name comes from its original application of serving both SSH and HTTPS on port 443, allowing SSH connections from inside corporate firewalls that block port 22.

Tool to send a magic packet to wake another host on the network. This must be enabled on the target host, usually in the BIOS.

This package contains a variety of tools for dealing with network configuration, troubleshooting, or servers. Utilities included are:

arping

Ping hosts using ARP.

clockdiff

Compute time difference between network hosts using ICMP TSTAMP messages.

ninfod

Daemon that responds to IPv6 Node Information Queries.

ping

Use ICMP ECHO messages to measure round-trip delays and packet loss across network paths.

rarpd

Answer RARP requests from clients.

rdisc

Populate network routing tables with information from the ICMP router discovery protocol.

tftpd

Trivial file transfer protocol server.

tracepath

Trace network path to an IPv4 or IPv6 address and discover MTU along the way.

BIRD is an Internet routing daemon with full support for all the major routing protocols. It allows redistribution between protocols with a powerful route filtering syntax and an easy-to-use configuration interface.

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.

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.

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.

Tunctl is used to set up and maintain persistent TUN/TAP network interfaces, enabling user applications to simulate network traffic. Such interfaces are useful for VPN software, virtualization, emulation, simulation, and a number of other applications.

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

Dante is a SOCKS client and server implementation. It can be installed on a machine with access to an external TCP/IP network and will allow all other machines, without direct access to that network, to be relayed through the machine the Dante server is running on. The external network will never see any machines other than the one Dante is running on.

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.

Socket6 binds the IPv6 related part of the C socket header definitions and structure manipulators for Perl.

bmon is a monitoring and debugging tool to capture networking-related statistics and prepare them visually in a human-friendly way. It features various output methods including an interactive curses user interface and a programmable text output for scripting.

This package provides CAN utilities in the following areas:

• Basic tools to display, record, generate and replay CAN traffic

• CAN access via IP sockets

• CAN in-kernel gateway configuration

• CAN bus measurement and testing

• ISO-TP (ISO15765-2:2016 - this means messages with a body larger than eight bytes) tools

• Log file converters

• Serial Line Discipline configuration for slcan driver

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

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.

NetAddr::IP manages IPv4 and IPv6 addresses and subsets.

Danga::Socket is an abstract base class for objects backed by a socket which provides the basic framework for event-driven asynchronous IO, designed to be fast. Danga::Socket is both a base class for objects, and an event loop.

mbuffer is a tool for buffering data streams with a large set of features:

• direct support for TCP based network targets (IPv4 and IPv6)

• ability to send to multiple targets in parallel (distribution mode)

• support for multiple volumes

• I/O rate limitation

• high/low watermark based restart criteria

• configurable buffer size

• on the fly MD5 hash calculation

• highly efficient, multi-threaded implementation

libnatpmp is a portable and asynchronous implementation of the Network Address Translation - Port Mapping Protocol (NAT-PMP) written in the C programming language.

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.

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