<div dir="ltr">I read the man page of tcpreplay. It does not sound it will do exactly what I wanted, unless the man page does not tell the whole story.

This of course, may require A+B IP addresses replaced with C+D IP addresses in the captured. If that's difficult due to internal checksum and such, I can set up C+D in a lab to have A+C's IP address instead.<br><br>
The man page sounds like it will work ok with the original client/server set ( Server A + Client C)<br><br><div class="gmail_quote">2008/10/15 Michael H. Warfield <span dir="ltr"><<a href="mailto:mhw@wittsend.com">mhw@wittsend.com</a>></span><br>
