Hey,

i want to send manipulated outgoing tcp packets in a tcp stream (about 4 packets/sec)

searched couple of days for a tool that is able to Sniff TCP Packets, change the acknowledgement number and checksum - and send the packet once more to the destination ip. Like "doubeling the action".

I found nothing. Every tool was just able to manually edit packets what means the acknowledgement number is way to "fast" for me to edit because past finding the right packet and changing the acknowledgement numer there are already 50-100 new packets being send.

Anyone got a idea how to manipulate outgoing tcp streams?

Some tools i tried:

pktbuilder
Distinct network monitor
softperfekt network analyzer
ethereal
packetcrafter
commview
packetyzer (someone said it would work with this one...wasnt able to manage it; maybe they talked about http post commands which can be send anytime)

Dose a tool like that even exist?

Or does a Proxy exist that can handel those TCP manipulations?
