Tcpreplay is a set of tools written which gives you the ability to use previously captured traffic in libpcap format to test a variety of network devices.
It allows you to classify traffic as client or server, rewrite Layer 2, 3 and 4 headers and finally replay the traffic back onto the network and through other devices such as switches, routers, firewalls, NIDS and IPS’s.
Tcpreplay supports both single and dual NIC modes for testing both sniffing and inline devices.
Features include:
-
- Uses the open standard pcap file format for which dozens of command line and GUI utilities exist.
- Includes the following tools:
- tcpprep – multi-pass pcap file pre-processor which determines packets as client or server and creates cache files used by tcpreplay and tcprewrite.
- tcprewrite – pcap file editor which rewrites TCP/IP and Layer 2 packet headers.
- tcpreplay – replays pcap files at arbitrary speeds onto the network.
- tcpbridge – bridge two network segments with the power of tcprewrite.
- flowreplay – emulates a network client using a pcap file as the basis of a TCP or UDP connection.
