Want to block Facebook and all of its trackers? Here’s a little script that looks up all IP addresses used by Facebook and blocks outbound connections using Firewalld.
#!/bin/bash # Get Facebook IP range from whois. IP=$(whois -h whois.radb.net '!gAS32934' | grep /) # Add a firewall rule for each entry. for ip in $IP do firewall-cmd --direct --add-rule ipv4 filter OUTPUT_direct 0 -d $ip -j DROP &> /dev/null done
