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

The Simple Network Management Protocol (SNMP) is a widely used protocol for monitoring the health and welfare of network equipment (e.g. routers), computer equipment and even devices like UPSs. Net-SNMP is a suite of applications used to implement SNMP v1, SNMP v2c and SNMP v3 using both IPv4 and IPv6.

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

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.

libyang is a YANG data modelling language parser and toolkit written (and providing API) in C. Current implementation covers YANG 1.0 (RFC 6020) as well as YANG 1.1 (RFC 7950).

Wireless networking GUI front-end for iwd, with supported functionality similar to that of iwctl. Features include viewing and connecting to available networks, managing known networks, provisioning new networks via WPS or Wi-Fi Easy Connect, and an indicator icon displaying connection status and signal strength.

GNU MAC Changer is a utility for viewing and changing MAC addresses of networking devices. New addresses may be set explicitly or randomly. They can include MAC addresses of the same or other hardware vendors or, more generally, MAC addresses of the same category of hardware.

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.

czmq provides bindings for the ØMQ core API that hides the differences between different versions of ØMQ.

This package provides a C implementation of a lightweight application-protocol for devices that are constrained their resources such as computing power, RF range, memory, bandwidth, or network packet sizes. This protocol, CoAP, is standardized by the IETF as RFC 7252.

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.

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.

This package provides a wireless network and device detector, sniffer, wardriving tool, and WIDS (wireless intrusion detection) framework. Kismet works with Wi-Fi interfaces, Bluetooth interfaces, some SDR (software defined radio) hardware like the RTLSDR, and other specialized capture hardware

Spiped (pronounced "ess-pipe-dee") is a utility for creating symmetrically encrypted and authenticated pipes between socket addresses, so that one may connect to one address (e.g., a UNIX socket on localhost) and transparently have a connection established to another address (e.g., a UNIX socket on a different system). This is similar to 'ssh -L' functionality, but does not use SSH and requires a pre-shared symmetric key.

Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ approach.

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.

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.

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

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

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

whois searches for an object in a WHOIS (RFC 3912) database. It is commonly used to look up the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system. It can automatically select the appropriate server for most queries.

For historical reasons, this package also includes mkpasswd, which encrypts passwords using crypt(3) and is unrelated to the Expect command of the same name.

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.
