add ipsets script
== Methods ==
There are different methods for blocking google..
=== Blocking using hosts file ===
You can edit your hosts file like the one showed [https://gist.github.com/Gaubee/6546308/ here].
An axample of [[hosts]] file, it contains a whole list of all google, twitter, facebook, etc... domains
Doing this all listed domains will be redirected to that ip address. You can easily change the ip addresses whit your local host 127.0.0.1 or whatever you want :)
=== Blocking using a firewall ===
echo "iptables -t mangle -X $2_ip" >> del_$2.sh
echo "iptables -t mangle -X $2_do" >> del_$2.sh
</pre>
== Use ipsets instead of iptables ==
If you block AS with a large number of entries, you will notice a performance hit when using iptables.
ipsets are much more efficient. Here is a similar script for setting up corporate monster blocking using ipsets on OpenWRT.
<pre>
#!/bin/sh
IP=`nslookup $1 | grep -E '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' | tail -n1 | cut -d\ -f3`
AS=`wget -q -O - http://ipinfo.io/$IP/org | cut -f1 -d \ | sed -e 's/AS//'`
echo '#!/bin/sh' > add_$2.sh
chmod 750 add_$2.sh
echo '#!/bin/sh' > del_$2.sh
chmod 750 del_$2.sh
NETWORKS=`wget -O - http://stat.ripe.net/data/announced-prefixes/data.yaml?resource=$AS|grep prefix\:|grep -v \:\:|awk '{print $3}'`
echo "ipset create $2_ip hash:net" >> add_$2.sh
echo "iptables -A forwarding_rule -m set --match-set $2_ip dst -j reject" >> add_$2.sh
for i in $NETWORKS; do echo "ipset add $2_ip $i" >> add_$2.sh; done
echo "ipset destroy $2_ip" >> del_$2.sh
