パッケージ: bittwist (1.0-1) [universe]

libpcap-based Ethernet packet generator

Bit-Twist is designed to complement tcpdump, which by itself has done a great job in capturing network traffic. Bit-Twist can regenerate the captured traffic onto a live network (the packets are generated from tcpdump trace file, generating a .pcap file).

Bit-Twist also comes with a comprehensive trace file editor to allow to change the contents of a trace file.

Generally, a packet generator is useful in simulating networking traffic or scenario, testing firewall, IDS, and IPS, and troubleshooting various network problems.

The Bit-Twist features are:

   * 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;
   * if you are teaching Computer Networks classes, you may find Bit-Twist
     useful as a practical teaching material. It gives your students a
     hands-on experience to learn various networking protocols etc.
