   Read me: Just compile it with:

            gcc ocs.c -o ocs -lpthread

            Then run it with: ./OCS xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy
        xxx.xxx.xxx.xxx=range start IP
        yyy.yyy.yyy.yyy=range end IP

      PAY ATTENTION: This source is coded for only personal use on
      your own router Cisco. Don't hack around.

      Special thanks to:
      Khlero with your patience this code is out there :*
