Pretty common issue running Tcpreplay in Linux. Basically the packets are being sent "out" the network interface and onto the wire, so they're never seen by the IP stack or your application, because for that to happen they have to come "in" on the network interface.
Solution is to run Tcpreplay on a different box. -- Aaron Turner http://synfin.net/ Twitter: @synfinatic Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. -- Benjamin Franklin On Mon, Feb 3, 2014 at 9:59 PM, Pritesh Acharya <priteshacha...@gmail.com> wrote: > > I'm using a Ubuntu 12.04 machine.
