UDP-Lite is based on User Datagram Protocol (UDP), but unlike UDP, where either all or none of a packet is protected by a checksum, UDP-Lite allows for partial checksums that only covers part of a datagram (an arbitrary count of octets at the beginning of the packet), and will therefore deliver packets that have been partially corrupted.
Kismet can also capture "Per-Packet Information" headers. Kismet also features the ability to detect default or "not configured" networks, probe requests, and determine what level of wireless encryption is used on a given access point. In order to find as many networks as possible, Kismet supports channel hopping.
A packet generator or packet builder is a type of software that generates random packets or allows the user to construct detailed custom packets. Depending on the network medium and operating system, packet generators utilize raw sockets , NDIS function calls, or direct access to the network adapter kernel-mode driver .
Packet Sender is an open source utility to allow sending and receiving TCP and UDP packets. It also supports TCP connections using SSL , intense traffic generation, HTTP(S) GET/POST requests, and panel generation.
WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs). [5] It aims to be lighter and better performing than IPsec and OpenVPN, two common tunneling protocols. [6]
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
tcpdump is a data-network packet analyzer computer program that runs under a command line interface. It allows the user to display TCP/IP and other packets being transmitted or received over a network to which the computer is attached. [3] Distributed under the BSD license, [4] tcpdump is free software.
For versions of Windows prior to Windows Vista, some packet analyzer applications such as Wildpackets' OmniPeek and TamoSoft's CommView for WiFi provide their own device drivers to support monitor mode. Linux's interfaces for 802.11 drivers support monitor mode and many drivers offer that support. [3]
