This is in effect the same code as 3.4.0pre3 so if you’ve already
updated, no reason to re-download. There are really only two issues
I’m currently aware of:

1) Doesn’t build with the Sun compiler
2) Packet injection doesn’t use the method documented, but rather the
one listed via: tcpreplay -V. This basically means unless you specify
something like –enable-force-pf (for Linux) or –enable-force-bpf
(for *BSD) you’re probably using something like libpcap or libdnet
which isn’t as efficient. It’s a very slight performance hit, so most
people won’t even notice.

Grab it here.

Now I’m switching gears and I’m starting to work on Tcpreplay 4.0 with
Abdelrazak Younes. Abdel has offered to create a cross platform QT
GUI for Tcpreplay and so I’m working on the backend to make this
possible. I’m really excited to have an experienced GUI developer
like Abdel helping out to make Tcpreplay easier for people to use.
