Linux ipblock

Why Block IP Addresses

When running my server I found in the logs that I was getting a lot of users that were just scanning my server for openings. So I decided to start blocking IP Addresses.

Fedora Block IP Addresses IPTable

This is a way of blocking IP Addresses in Fedora.

This command will add an IP Address to the blocked list.

 # iptables -A INPUT -s 65.55.44.100 -j DROP

This command shows all the iptable references.

 # iptables -L

This will remove and IP Address from the IPTable rules.

 # iptables -D INPUT -s xx.xxx.xx.xx -j DROP
