#  PURPOSE:  This is a Bash script that launches an nmap "Slow              #
#            comprehensive scan" against IP addresses identified as attack  #
#            nodes by Fail2Ban (http://www.fail2ban.org).                   #
#                                                                           #
#            It reads a list of IP addresses from a text file containing    #
#            one IP address on each line.                                   #
#                                                                           #
#            It will then save the scan output to a file for later review.  #
#                                                                           #
#  NOTES:    This script intended to be run inside a GNU screen             #
#            (https://www.gnu.org/software/screen/) session so that it may  #
#            run detached.                                                  #
