Retransmit captured data via a TCP/IP connection

asked 2021-05-05 20:26:43 +0000

Hello,

Is there a way to retransmit captured data via a TCP/IP connection? I have a TCP Client that makes a connection to a server and waits for any incoming traffic (pcapng data). In order to test this client I need to send it pcapng files. Can this be done by suing Wireshark? Any help will be much appreciated. Thank you in advance.

I never had a need to inject packets, but Colasoft link text has packet replay and packet builder Windows freeware software.

"TCP is problematic ..."

Wireshark Wiki - Traffic generators
Most of the time people see TCP so they assume tcpreplay would be the way to go but it's definitely not plug and play.
If you don't mind python and a little programming, scapy can read pcap/pcapng files and send packets.

There is a new tool (WireReplay) out from the WireEdit company. If you give it a try, please share your experience back here. :-)
