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.

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.

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.

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.

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

NDisc6 is a collection of tools for IPv6 networking diagnostics. It includes the following programs:

• ndisc6: ICMPv6 Neighbor Discovery tool.

• rdisc6: ICMPv6 Router Discovery tool.

• tcptraceroute6: IPv6 traceroute over TCP.

• traceroute6: IPv6 traceroute over UDP.

• rdnssd: Recursive DNS Servers discovery daemon.

libndp contains a library which provides a wrapper for IPv6 Neighbor Discovery Protocol. It also provides a tool named ndptool for sending and receiving NDP messages.

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

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.

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.

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

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.

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 package provides the NBD (Network Block Devices) client and server. It allows you to use remote block devices over a TCP/IP network.

Miredo is an implementation (client, relay, server) of the Teredo specification, which provides IPv6 Internet connectivity to IPv6 enabled hosts residing in IPv4-only networks, even when they are behind a NAT device.

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

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.

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.

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.

Yggdrasil is an early-stage implementation of a fully end-to-end encrypted IPv6 network. It is lightweight, self-arranging, supported on multiple platforms and allows pretty much any IPv6-capable application to communicate securely with other Yggdrasil nodes. Yggdrasil does not require you to have IPv6 Internet connectivity - it also works over IPv4.

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.

VDE is a set of programs to provide virtual software-defined Ethernet network interface controllers across multiple virtual or physical, local or remote devices. The VDE architecture provides virtual counterparts to hardware components such as switches and cables.

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
