Script to block tracking from omniture etc. Subject description: blocking ip's of scripts in webpages that track you
this script was posted by a colleague on the Badphorm Forum. It is his work and I am posting it here for wider use. Cut and paste this using your favourite editor.
#! /bin/sh -e
# Shell script to read a file of IP addresses (in CIDR notation),
# one per line and terminated with a last line of "eof" and to
# update iptables to REJECT (with reason icmp-admin-prohibited) any outbound traffic
# to these addresses. Will output a message to your syslog for each block.
# 1) You must have iptables installed (I think most distros will have it installed already).
# 2) You must run this script as root (I use crontab to run it once a day and on reboot)
# 3) Don't forget to make this script exexcutable!
# 4) You can make your blocklist file editable by a trusted non-root user if you wish.
# ***** EDIT LINE BELOW with location of your blocklist file *****
# Clear existing iptables
# Configure iptables with addresses we block from going out
while read line
/sbin/iptables -A OUTPUT -d $line -j LOG --log-prefix "BLOCKED TRACKING SITE: "
/sbin/iptables -A OUTPUT -d $line -j REJECT --reject-with icmp-admin-prohibited
done < $IPLIST
# Display new iptables
#end of blocktracker
save the above as blocktracker make it executable and put it in /usr/local/bin
the data file copy this list of ip numbers including the eof at the end and save as 'tracking_list_ip.data', put this in /
