[CentOS] ipsets/iptables question

Hello,

I have ipsets setup with a set of ip address that are badbots that won't comply with robots.txt

This is a home server and these are most likely up to no good.

I came up with a script to extract ip address from my access_log then another script to take ips and import them into my blacklist set.

(see my scripts in the .htaccess thread)

I can set these up as cron jobs but I'm not sure about the following:

1) after importing/updating the set, do I need to perform a, ipset save blacklist

Since I haven't changed the rule in iptables, do I need to run these? 2) service iptables save 3) service iptables restart

Thank!!
