Hi, For a project that some of us are working on we have created a little program called mkcap.c.
This program can generate an ascii capture file (which can be converted with text2pcap) of reasonable format TCP segments. You can select a bunch of parameters associated with the connection, like src IP, dst IP, src port, dst port, src ISN, etc. We are working on allowing you to also specify that packets or acks be dropped in various ways and we want the program to generate the sort of traffic that a real TCP impl might generate. If nothing else, it is useful for generating pretty time sequence analysis graphs.
