Re: [Tcpreplay-users] trunc to mtu

[yassine a. <ens...@ho...>]

Hi,

ok as you said i find that the fragroute is embedded in my tcprewrite version.
But still i have problem:
when i try fragmentation it shows me back error : Fatal Error: Error processing packet via fragroute: skipping non-IP packet
i have tried both ip_frag (size) and tcp_seg (size) options
i could not figure out the problem have you any idea?
other question concerning the fragroute config file is it the unique method to give options of fragroute.
thanks
