Added 2 more blocklist:
EmergingThreats.net Command and Control IPs
EmergingThreats.net compromised hosts
Updated script on the first post.
For those interested in a better way to crate a blocklist on centos/debian take a look at:
i wrote this script using ipset and iprange to compact the resulting blocklist as possible in order to increase the performance, i think can be easily adapted on nethserver (may be the next update 
)
