WARNING: BIG SECURITY PROBLEM.

The software sends an email to its author, with info on YOUR network!

Otherwise, some problems:

1) The configure script does not test the presence of the libpcap library
:-( On Debian, you have to install the package
"libpcap0.8-dev". configure should test it.

Same problem for libxml2.

2) Once compiled, I cannot use the tool:

% ./ndpmon -d eth0
./ndpmon: invalid option -- d

But -d is in the usage message:

~/tmp/ndpmon-0.1 % ./ndpmon -h
./ndpmon: invalid option -- h
Usage: ndpmon [-d device] [-n number_of_packets] [-F filter_string] [-f configuration file]

(It is probably -i)

3) On NetBSD, it does not compile (again, configured detected no
problem):

preston:~/tmp/ndpmon-0.1 % make                 
gcc -Wall -pedantic -O3 -c `xml2-config  --cflags` ndpmon.c -g
