Hello, I have a pcap file with olny TCP tarffic. I would like to feed that file to tcpreplay in order to generate the same TCP traffic that the pcap file has. But I have notice that the packets that tcpreplay is generating have no TCP headers. Because the pcap file is created from text2pcap and text2pcap has not recreate the whole packet with the TCP header. Based on the text2pcap man page I could use the -T option, which is to define a specific source and destination port, and text2pcap is going to generate a dummy header for the packets. So I done that and all packets have the same destination port and source port, and the TCP flags in all packets are the same. Specifically in all TCP packets the ACK flag is on. This of cource is an undesirable result because is giving a completely different traffic from the one is in the original captured pcap file. In fact the original captured file has TCP packets with different TCP flags. Does anyone know how to make text2pcap to give me back the whole packet TCP headers?
