Tcpreplay is a lightweight suite of utilities written by Aaron Turner specially for UNIX operations systems and which enables you to use previously captured traffic in the libcap format in order to test various network devices.

What is more, Tcpreplay helps you classify traffic as client or server and rewrite Layer 2, 3 or 4 headers and replay the traffic back onto the network through other devices such as firewalls, routers, IPS's and NIDS. On top of that, Tcpreplay comes with support for both single and dual NIC modes for testing inline devices and sniffing.

To start using Tcpreplay, you shoult run tcpprep against a pcap file in order to generate a cache file capable to split the traffic between client and server. This is useful if you need to test an inline device. You can also use tcprewrite to edit the packets and tcpreplay to replay the pcap onto the network to perform the test.
