Bit-Twist (bittwist / bittwiste)

Bit-Twist (bittwist) — a simple but powerful packet generator Ethernet II (IEEE 802.3) based on library analysis of network data is the PCAP (Libpcap).

bittwist (Bit-Twist) is an extremely flexible tool for the generation of packets (Packet Generator), developed as a complement to command line tools tcpdump, allowing you to intercept and analyze network traffic on the specified interface (sniffer / sniffer).

Utility bittwist you can restore the network captured traffic packets are generated from the trace file tcpdump (*.pcap). Supports work with several files, send packages with a certain speed or full speed of the channel.

Bit-Twist includes utility bittwiste, it is a complete editor of trace files, with control over the majority of headers of Ethernet, ARP, IP, ICMP, TCP and UDP. You can add PCAP-file additional payload to existing packets, to select a specific range of packets and save them in another trace file.

The packet generator Bit-Twist is useful for modeling network traffic or scenario, testing firewall, troubleshoot network issues and much more. Can also be used as a textbook in the study of computer networks, giving practical experience in the study of various network protocols.
