different code, same task

i’ve coded similar plugin independently when found this plugin already exist…

http://cvs.pld-linux.org/cgi-bin/cvsweb.cgi/packages/nagios-plugin-check_iptables/check_iptables

differences are with my plugin:
– can setup needed sudo rules if invoked with -S argument
– you can specify warning and critical levels how many rules you need to have present
– can check other tables/chains than filter/INPUT via command line args.
