Create TCP/IP Packets Using These 7 Cool Tools

TCP/IP, the de facto standard for transmitting data over networks provides essential info regarding end-to-end connectivity specifying how data should be formatted, addressed, transmitted, routed and received at the destination. Here are 7 awesome tools for creating TCP/IP packets.

1.Nemesis

Nemesis is a command-line network packet crafting and injection utility for UNIX-like and Windows systems. Nemesis, is well suited for testing Network Intrusion Detection Systems, firewalls, IP stacks and a variety of other tasks. As a command-line driven utility, Nemesis is perfect for automation and scripting.

2.hping

hping is a command-line oriented TCP/IP packet assembler/analyser. The interface is inspired to the ping(8) unix command, but hping isn't only able to send ICMP echo requests. It supports TCP, UDP, ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many other features.

3.Scapy

Scapy is a powerful interactive packet manipulation program. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more.

4.Yersinia

Yersinia is a network tool designed to take advantage of some weakeness in different network protocols. It pretends to be a solid framework for analysing and testing the deployed networks and systems.

5.packETH

GUI and CLI packet generator tool for ethernet. It allows you to create and send any possible packet or sequence of packets on the ethernet link.

6.SendIP

SendIP has a large number of command line options to specify the content of every header of a NTP, BGP, RIP, RIPng, TCP, UDP, ICMP or raw IPv4 and IPv6 packet. It also allows any data to be added to the packet.

7.Mausezahn

Mausezahn is a free fast traffic generator written in C which allows you to send nearly every possible and impossible packet. It is mainly used to test VoIP or multicast networks but also for security audits to check whether your systems are hardened enough for specific attacks.
