The Tcpreplay suite includes the following tools:

•  - multi-pass pcap file pre-processor which determines packets as client or server and creates cache files used by tcpreplay and tcprewrite
•  - pcap file editor which rewrites TCP/IP and Layer 2 packet headers
•  - replays pcap files at arbitrary speeds onto the network
•  - Replays network traffic stored in a pcap file on live networks using new TCP connections
•  - replays & edits pcap files at arbitrary speeds onto the network
•  - bridge two network segments with the power of tcprewrite
•  - raw pcap file decoder and debugger

 除了tcpliveplay以外，其他工具都只是单纯的发包，不会建立TCP连接，也不会维护SEQ/ACK，tcpliveplay测试了一下也没有成功？

tcpliveplay eth0 52716.pcap 10.125.52.26 fa:16:3e:f1:5c:28 random

tcpreplay --intf1=eth0 52716.pcap
