Re: need utillity that can do complex tcp replay

["Andre Gironda" <andre () operations net>]

It appears that you have already found it.  what's wrong with tcp-replay?

i'm not sure exactly what you mean by "simulated client".  are you
looking for interactivity?

i saw this problem/need described well in chapter 4 of microsoft press
"Hunting Security Bugs".  the authors of the book provide a tool
called MITM (on their companion site). The book also provides a link
to a tool called Interactive TCP Relay
http://www.imperva.com/application_defense_center/tools.asp

the Unix opensource tools netcat, scapy, and blackbag (especially
telson, blit) may also help out.

also, in particular for HTTPS, you may want to consider using a local
http proxy such as the very popular burpproxy.  there are scripts to
parse and replay burp's logfiles generated from request/responses
available in various places, including Network Security Tools from
O'Reilly.
