Presumably the OP knows the port IP address and port number on which
the server is listening, so wouldn't it be simpler to just capture TCP
traffic to/from that IP/port?
Then you can play it back using tcprewrite, tcpreplay, et al.
But, I don't see how that's going to work. The OP seems to want to
capture a TCP session and then "replay it" so that the client from the
session ends up talking to a different server during the replay. The
chances of the new server starting up a connection with the same ACK
sequence number is practially nil isn't it?
