IP-Tables script to blacklist some autonomous systems
Extract anywhere and run make, defaults to /usr/local/bin.
Then run: blacklist-as -u
to create the configuration and then:
blacklist-as -i
to install the service that loads the configuration at boot time.
run: blacklist-as -c
then remove the remaining files in /usr/local/bin
By default all incoming connections are blocked, autonomous systems that should completely be blocked can be configured in /usr/local/bin/as_blacklist.conf
