This directory contains source code for tcpdump, a tool for network
monitoring and data acquisition. This software was originally
developed by the Network Research Group at the Lawrence Berkeley
National Laboratory. The original distribution is available via

Tcpdump uses libpcap, a system-independent interface for user-level
tcpdump.org; see http://www.tcpdump.org/ .
Once libpcap is built (either install it or make sure it's in
-../libpcap), you can build tcpdump using the procedure in the INSTALL

file.
The program is loosely based on SMI's "etherfind" although none of the
