Subject: Re: libpcap and tc filters

I don't think so. I tried different versions of tcpreplay.

The solution didn't work on 3 different ubuntu 10.04 machines with
2.6.32-32 (actually one of them had 2.6.32-31) but it DID work on a
fedora core 15 virtual machine with a newer kernel as well as a second
virtual machine with on which I installed stock ubuntu 11.04 just for
this test. It has 2.6.38 i think. On the last three machines (the
third ubuntu 10.04 as well as fc15 and ubuntu 11.04 tcpreplay came
straight from the repository).

Just to make myself clear - earlier, I tried the solution on a 10.04
physical box with various versions of tcpreplay, libpcap, and
iproute2. nothing worked.
