Actually, it's more then just TCP windowing. Probably the single biggest issue is that tcpreplay *never* EVER reads from the network. So yeah, when the server replies to your TCP Syn with a Syn/Ack and sets it's initial sequence number, it never reads that and can't even complete a 3 way handshake.
So yeah, the FAQ is correct. I didn't just write that to confuse people. :) As for the name, well I actually didn't name tcpreplay... I just took over the project something like 10 years ago. I'm pretty sure it was named this way as an opposite of tcpdump, which as you know does more then just TCP too. -Aaron On Wed, Oct 12, 2011 at 8:11 AM, James Bergeron <james.berge...@alcatel-lucent.com> wrote: > Yes on the tcp windowing. > > Canned traffic, "pre-determined already captured in a pcap" > > > On 10/12/2011 10:56 AM, narke wrote: >> What mean 'canned traffic'?
