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

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.

wireproxy-awg is a completely userspace application that connects to a WireGuard peer, and exposes a SOCKS5/HTTP proxy or tunnels on the machine.

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.

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

C library implementation of RaptorQ Forward Error Correction for Librecast. RFC6330 (IETF) describes the RaptorQ proposed standard, which LCRQ more-or-less follows. The primary focus has been on building a fast, simple and dependency-free FEC implementation for use with Librecast, and not on strict standards compliance. The code does, however, fairly closely follow the RFC.

Nanomsg is a socket library that provides several common communication patterns. It aims to make the networking layer fast, scalable, and easy to use. Implemented in C, it works on a wide range of operating systems with no further dependencies.

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.

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.

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

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.

parprouted is a daemon for transparent IP (Layer 3) proxy ARP bridging. Unlike standard bridging, proxy ARP bridging can bridge Ethernet networks behind wireless nodes. Normal layer 2 bridging does not work between wireless nodes because wireless does not know about MAC addresses used in the wired Ethernet networks. This daemon can also be useful for making transparent firewalls.

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.

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

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.

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.

Open vSwitch is a multilayer virtual switch. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, IPFIX, RSPAN, CLI, LACP, 802.1ag).

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

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.

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.

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

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

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.

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.
