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.

Iodine tunnels IPv4 data through a DNS server. This can be useful in different situations where internet access is firewalled, but DNS queries are allowed. The bandwidth is asymmetrical, with limited upstream and up to 1 Mbit/s downstream.

Wireshark is a network protocol analyzer, or packet sniffer, that lets you capture and interactively browse the contents of network frames.

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.

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.

Nebula is a peer-to-peer networking tool based on the Noise Protocol Framework. It is not a fully decentralized network, but instead uses central discovery nodes and a certificate authority to facilitate direct, encrypted peer-to-peer connections from behind most firewalls and NAT layers.

Slurm is a network load monitor. It shows real-time traffic statistics from any network device in any of three ASCII graph formats.

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.

Zyre provides reliable group messaging over local area networks using zeromq. It has these key characteristics:

• Zyre needs no administration or configuration.

• Peers may join and leave the network at any time.

• Peers talk to each other without any central brokers or servers.

• Peers can talk directly to each other.

• Peers can join groups, and then talk to groups.

• Zyre is reliable, and loses no messages even when the network is heavily loaded.

• Zyre is fast and has low latency, requiring no consensus protocols.

• Zyre is designed for WiFi networks, yet also works well on Ethernet networks.

This package provides a multi-threaded TFTP server that implements all options, including all extensions, as specified in RFC 1350, RFC 2090, RFC 2347, RFC 2348, RFC 2349 and RFC7440. Atftpd also supports a multicast protocol known as mtftp, which was defined in the PXE specification.

The server is socket activated by default but supports being started from inetd as well as in daemon mode.

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.

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.

YAZ is a C/C++ library for information retrieval applications using Z39.50, SRU or Solr Web Service protocols for information retrieval. It also offers ZOOM API implementing them.

Hashcash is a proof-of-work algorithm, which has been used as a denial-of-service countermeasure technique in a number of systems.

A hashcash stamp constitutes a proof-of-work which takes a parametrizable amount of work to compute for the sender. The recipient can verify received hashcash stamps efficiently.

This package contains a command-line tool for computing and verifying hashcash stamps.

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.

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.

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.

IO::Socket::INET6 is an interface for AF_INET/AF_INET6 domain sockets in Perl.

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.

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

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).

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

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

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