T50

T50 is a versatile network packet injector designed for testing and research purposes on *nix systems. It supports 15 different protocols including TCP, UDP, ICMP, IGMPv2/3, EGP, DCCP, RSVP, RIPv1/2, GRE, ESP, AH, EIGRP, and OSPF, making it suitable for comprehensive network protocol testing and stress evaluation.

The tool excels in high-performance packet generation with features like flooding mode, TCP options manipulation, and extensive protocol-specific customization. It supports CIDR notation for targeting IP ranges and can achieve impressive throughput rates of approximately 1,000,000 packets per second when using turbo mode.

While powerful for legitimate network testing, the author explicitly denies its use for DoS/DDoS attacks and encourages responsible usage. T50 provides granular control over packet headers and protocol fields through extensive command-line options.

T50 operates as an experimental mixed packet injector that generates and transmits customized network packets across multiple protocols. It constructs packets with user-specified or randomized header fields, supporting protocol encapsulation (like GRE), TCP flag manipulation, IP fragmentation, and protocol-specific options. The tool uses high-performance techniques including turbo mode for maximum throughput and can send all supported protocols sequentially when using the T50 protocol option. Flood mode supersedes packet thresholds for continuous transmission until interrupted.
