-- the sentinel project v1.0 : by bind : copyright (c) 2000, 2001 --
   
   The sentinel project is an implementation of effective remote
   promiscuous detection techniques.
   For portability purposes, the sentinel application uses the libpcap
   and libnet libraries.
   
   To install this software the following libraries are required:
     * libnet ([1]http://www.packetfactory.net/Projects/libnet)
     * libpcap ([2]http://www.tcpdump.org)
     * posix thread library
   
   This software currently compiles and functions correctly under:
     * openbsd 3.0-beta ([3]http://www.openbsd.org)
     * freebsd 4.0
     * netbsd 1.5.2
     * linux 2.4.x

   Sentinel usage:
     ./sentinel [options] [methods] [-c <x.x.x>] [-f <filename>] [host]
   
   methods:
     -a arp test
     -d dns test
     -e icmp etherping test
   
   options:
     -c <x.x.x> class c to scan
     -f <file> file of ip addresses
     -i <device> network interface
     -n <number> number of packets to send
   
   Example usage:
     # ./sentinel -aed -c 10.2.2
   
     sentinel will scan the class c 10.2.2 and test each machine against
   the arp,
     etherping and dns tests.
   
     # ./sentinel -aed -f ./ips
   
     sentinel will read ip addresses from the 'ips' file and test each
   machine
     against the arp, etherping and dns tests.
   
     # ./sentinel -aed 1.1.1.1
   
     sentinel will test 1.1.1.1 for the arp, etherping and dns tests.
