Retransmissions while blocking TCP Stack's RST?

[Cynic <cynic () progrock com>]

Hi,

I am looking for an application for *NIX, that can replay captured packets, while dropping, the TCP Stacks responses.
Let's assume I replay a SYN, and receive a SYN-ACK, my host's TCP Stack immediatley replies with a RST since it was not 
aware a connection was to be opened.
So I am looking for some low-level retransmission application for *nix such as Network monitor for NT. (I believe it 
does this.)

Thanks a lot!

Cynic.
