I am trying to come up with a iptables rule that will deny ip certain ip addresses that I can load/unload into a file. To clarify...i run a ftp server and sometimes people screw around and I want to ban them from logging in. I need a way to add these ip's into a 'ban list'. I don't want to add a new rule every time however with a separate rule for each ip. Is there a way to make a file such as 'banned_ips' and have a rule look into that file to decide if the ip can log in or not? Thanks, Mark
