US Only VPS (Ubuntu Specific)

This guide worked for me with a few exceptions,

I additionally Ran

apt-get install xtables-addons-common xtables-addons-dkms xtables-addons-source

Once this is done, I change my default-accept policy to US Only accept.

iptables -A INPUT -m geoip –src-cc US -j ACCEPT
iptables -I INPUT -j DROP
iptables-save

Simple way to reduce the excessive Fail2Ban occurrences.
