net/bittwist 4.7 DragonFly

Bit-Twist is a simple yet powerful libpcap-based Ethernet packet generator. It is designed to complement tcpdump, which by itself has done a great job at capturing network traffic.

These are just a few significant features that makes Bit-Twist unique and stands out as one of the best Ethernet packet generator package made available to the open source community.

• Runs on Linux, BSD, macOS, and Windows
• Send multiple trace files at a time
• Send packets at a specific speed or line rate in Mbps
• Comprehensive trace file editor with control over most fields in Ethernet, ARP, IP, ICMP, TCP, and UDP headers with automatic header checksum correction
• Append user payload to existing packets after a specific header
• Select a specific range of packets and save them in another trace file
• Highly scriptable - with proper manipulation you can turn Bit-Twist into an extremely flexible packet generator tool!
