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. (untested)
# iptables -D INPUT -s xx.xxx.xx.xx -j DROP
Fedora Block PORTS from the out side
This will block ports from outside connections.
# iptables -A INPUT -p tcp --dport 3306 -J DROP
