Install tcpreplay on Ubuntu or Debian $ sudo apt-get install tcpreplay If you would like to install tcpreplay on Linux, you can refer to the following distro-specific instructions. Tcpreplay is useful when you are testing network devices and middleware, such as routers, switches, firewalls and intrusion detection/prevention systems, because it allows you to test the devices under a controlled environment using reproducible scenarios. In order to use tcpreplay, you first need to capture live network traffic using packet capture tools such as tcpdump, rewrite TCP/IP packet headers of the captured packets appropriately (usually MAC and IP addresses), and then re-inject the packets on to any arbitrary network under consideration. Tcpreplay is a suite of command-line utilities that are used to replay previously captured packet dumps in a real network.
