<P>
As of tcpreplay v1.4, you'll need to have libpcap installed on your
system. As of v2.0, you'll need at least version 0.6.0 or better,
but I only test our code with the latest version. Libpcap can be obtained
on the tcpdump homepage<A NAME="tex2html6"

</H2>

<P>
Tcpreplay v1.3 is the last version to support the old libnet API (everything
before 1.1.x). As of v1.4 you will need to use Libnet 1.1.0 or better
which can be obtained from the Libnet homepage<A NAME="tex2html7"
  HREF="#foot138"><SUP><SPAN CLASS="arabic">7</SPAN></SUP></A>.

</H2>

<P>
Starting with v2.0, tcpreplay can use libpcapnav to support the jump
offset feature. If libpcapnav is not found on the system, that feature
will be disabled. Libpcapnav can be found on the NetDude homepage<A NAME="tex2html8"
  HREF="#foot139"><SUP><SPAN CLASS="arabic">8</SPAN></SUP></A>.

<SPAN CLASS="arabic">6</SPAN>.<SPAN CLASS="arabic">4</SPAN> Tcpdump</A>
</H2>

<P>
As of 2.0, tcpreplay uses tcpdump (the binary, not code) to decode
packets to STDOUT in a human readable (with practice) format as it
sends them. If you would like this feature, tcpdump must be installed
on your system.

<P>
N<SMALL>OTE:</SMALL> The location of the tcpdump binary is hardcoded in
tcpreplay at compile time. If tcpdump gets renamed or moved, the feature
will become disabled.
