Well, I am not sure but, does tcpreplay takes care of sequence numbers? May be the victim is selecting different initial sequence number everytime, Does tcpreplay modifies the sequence number accordingly? On 10/29/06, nnp <version5 () gmail com> wrote:
Hey, I'm currently testing the Asterisk PBX for vulnerabilities but I just encountered an interesting problem when trying to recreate a crash. Using a fuzzer I can crash it in the exact same place every time. I am recording these session using ethereal (wireshark) and then replaying them using tcpreplay e.g sudo tcpreplay -i lo dieAsterisk.eth Anyways, the problem is Asterisk completely ignores the data sent to it via tcpreplay. I'm not sure what the issue could be. The packets replayed are identical. Is anyone aware of any checksum that takes timing into account or whatnot in Asterisk? Thanks, nnp -- http://silenthack.co.uk
