<p><b>Bit-Twist</b> is a powerful <a href="Libpcap" class="mw-redirect" title="Libpcap">libpcap</a>-based Ethernet <a href="Packet_generator" title="Packet generator">packet generator</a> and <a href="Packet_capture" class="mw-redirect" title="Packet capture">packet capture</a> editor, written in POSIX-compliant C, designed to complement <a href="Tcpdump" title="Tcpdump">tcpdump</a> by replaying captured traffic from pcap files onto live networks. It supports <a href="Microsoft_Windows" title="Microsoft Windows">Windows</a> (using <a href="Pcap#Npcap" title="Pcap">Npcap</a>), <a href="Linux" title="Linux">Linux</a>, <a href="Berkeley_Software_Distribution" title="Berkeley Software Distribution">BSD</a>, and <a href="MacOS" title="MacOS">macOS</a>, allowing the editing of key fields in <a href="Ethernet" title="Ethernet">Ethernet</a>, <a href="Address_Resolution_Protocol" title="Address Resolution Protocol">ARP</a>, <a href="IPv4" title="IPv4">IPv4</a>, <a href="IPv6" title="IPv6">IPv6</a>, <a href="Internet_Control_Message_Protocol" title="Internet Control Message Protocol">ICMP</a>, and <a href="Transmission_Control_Protocol" title="Transmission Control Protocol">TCP</a>/<a href="User_Datagram_Protocol" title="User Datagram Protocol">UDP</a> headers. It can also generate pcap files from its built-in templates, enabling packet creation without existing capture files, along with payload generation from uniformly distributed random bytes or fixed bytes, such as hex streams from <a href="Wireshark" title="Wireshark">Wireshark</a>. Ideal for testing <a href="Firewall_(computing)" title="Firewall (computing)">firewalls</a>, <a href="Intrusion_detection_system" title="Intrusion detection system">IDS</a>, <a href="Intrusion_detection_system#Intrusion_prevention" title="Intrusion detection system">IPS</a>, <a href="Router_(computing)" title="Router (computing)">routers</a>, <a href="Network_switch" title="Network switch">switches</a>, <a href="Load_balancing_(computing)" title="Load balancing (computing)">load balancers</a>, and other network equipment, it delivers performance that matches the line rate of <a href="Network_interface_controller" title="Network interface controller">NIC</a>, up to 10Gbit/s.
