Notes:

- The LibpcapFilter filter needs the Perl Net::Pcap package. This
  module in turn requires that you have libpcap installed.

  URL: ftp://ftp.ee.lbl.gov/libpcap.tar.Z

  To be able to put the network interfaces in promiscuous mode, the
  LibpcapFilter filter needs to run as root. Because right now there
  is no mechanism to selectively run portions of AAFID as root, these
  filter and agents are provided mostly as exercises. We do not
  recommend that you run the whole AAFID system as root!
