Hello geekphilosopher :)

I did not write the c myself, I am just being lazy and thought I could try to run the c in Perl and see how it works :).

there is a similar perl script which do the same thing as the c, but it is not portable on my ppc linux (yellow dog linux), see:

http://perlmonks.org/?node=p0f

since the c program works both on x86 and ppc linux, so I guess I could wrap it in Perl and solve the portability problem.
