Hi. Thanks for building and maintaining the tool! I want to use tcpreplay to replay some online post requests. But I can’t even replay the requests on my test environment. I read the docs but I can’t find an answer, really appreciate if you could help.
!1009 $ ifconfig
eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

Tcpdump command:
sudo tcpdump -i eno1 -s 0 -A 'tcp dst port 9090 and (tcp[((tcp[12:1] & 0xf0) >>
2):4] = 0x504f5354)' -vv -w /tmp/post.pcap
Please kindly find pcap file in attachment, thanks
Tcprewrite:
tcprewrite --portmap=9090:9990 --infile=post.pcap --outfile=port.output.pcap
Tcpreplay
sudo tcpreplay -i eno1 port.output.pcap
When I use the command, I can’t see the request from server log. But when I use
tcpdump to listen to the port, I can see the replayed request.
Could you please help me to find out where the problem is?
Thanks
