#!/bin/bash
ip1='FILL-SOURCE-IP'; ip2='FILL-DEST-IP'; host='FILL-HOSTNAME'; curl http://$host | grep -o '<a.*href=.*>' | grep "http://$host" | sed -e 's/<a .*href=['"'"'"]//' -e 's/["'"'"'].*$//' -e '/^$/ d' > links.txt; for link in `cat links.txt`; do path=`echo -n $link | cut -d "/" -f 4-`; curl --header "Host: $host" "http://$ip1/$path" > ip1.html; curl --header "Host: $host" "http://$ip2/$path" > ip2.html; echo; echo "Diff http://$ip1/$path"; echo; diff ip1.html ip2.html; done
