Hi Mike,

I'd suggest recording a raw form of suitable traffic via tcpdump, then
editing it according to your needs, and then replaying it onto your
network using tcprelay or similars. Netdude (netdude.sf.net) is ideal
for creating small, specific patterns for tickling your IDS. It was the
main purpose we developed it for when working on traffic normalization
years ago. You're very welcome to pop by our mailing list in case you
have any questions.

Good luck,
Christian.

Or does anyone know of a proxy application like Achilles or Burp that
works at the TCP level so that I could just drop the ACK packets while
they were on their way out of the client machine?

Hi everyone,

I need to have a server application retransmit some TCP packets to my
client to test my IDS.
