I need to find utility for testing of application debugging issue that can replay captured ip traffic, something similar to description at: http://tcpreplay.synfin.net/trac/wiki/flowreplay Basicly what I want is to capture data for several hours on the server (preferably with tcpdump) and then I'd like to replay requests that came to server from another computer that would act as a client and simulate this traffic including using the same ip addresses as on the original captured packets, but all would be sent to different server which has basically same setup & data as original but with debugging & testing utilities (and with possibility to run application in debugging mode). So what would be replayed would all be new TCP requests but contain same data as original and testing server would have direct 1-1 connection to a "simulated client" with this captured data and this client would need to be able to replay TCP packets creating sequence that is same order as original. Note that what I need to debug is actually HTTPS which may present additional problems (including various timing issues since Expires header can not be rewritten without decoding encrypted data, but for that I'll reset time on the test server to be exactly same as it was when data was captured; but I'm sure there other other issues). While I'd greatly prefer to find unix-based open-source package that can do above, I'll consider other including commercial alternatives. If you know of something that can do it, please reply. -- William Leibzon Elan Networks [email protected]
