NMAP scan script for repeatable scans of the same target. Can target hosts or range of hosts

nmap_TEMPLATE.sh

#!/bin/bash
# This script allows you to perform an nmap scan against targets listed in a TXT file.
# Target can be a single IP, a hostname, or a network range (i.e. 192.168.2.0/24; 10.1.2.10-25)
# Nmap will output in XML file, which then will be converted to HTML for web viewing.
# The file will be copied to the web server folder when it can be viewed in a browser. 
# It may be publically viewable, so choose wisely!
# Scan can be run on a schedule, it will save old scan copies
# Optionally, use mailx or sendmail or whatever you want to email yourself when the scan is done
# Exit script on error
set -ex
# Substitute for client acronym, i.e.: NWO, or anything you want. Will be used later as folder name
CLIENT="xxxxx"
# Don't forget to create the $CLIENT.txt file with the scan target host, IP, or network range
# Capture output to a log file
exec &> /var/www/$CLIENT.log
# Create an archive folder to old reports if the folder doesn't exist
mkdir -p -v /var/www/$CLIENT/$CLIENT/old
# Run the actual nmap scan
nmap --script vuln --open -sV -O --osscan-limit -R -sS -T4 -Pn -oX /var/www/$CLIENT/$CLIENT_scan.xml -iL $CLIENT.txt
# Move old reports into archive folder
mv -v /var/www/$CLIENT/*_report.html /var/www/$CLIENT/old/
# Convert the result XML file into HTML file
xsltproc /var/www/$CLIENT/$CLIENT_scan.xml -o "/var/www/$CLIENT/$CLIENT_`date +%m%d%y`_report.html"
cd /var/www/$CLIENT
# Create a symlink to the report file for easier web browsing
ln -s -f $CLIENT_*_report.html index.html
# Give proper permissions to be web-viewable
chmod 775 /var/www/$CLIENT/*
# Change ownership to your web server user
chown -v -R www:www /var/www/$CLIENT/* /var/www/$CLIENT.*
# Send email alert that scan is done and include the report and the URL in the email
echo "Access the report here: http://your.website.com/$CLIENT/ "   | mailx -r "root@localhost" -s "Nmap scan completed!" -q "/var/www/$CLIENT.log" -S smtp="smtp.gmail.com:587" -S smtp-use-starttls -S smtp-auth=login -S smtp-auth-user="user@email.com" -S smtp-auth-password="xxxxXXxxxXXx" -S ssl-verify=ignore user@email.com
echo "Access the report here: http://your.website.com/$CLIENT/ "
# Profit!
