hi all,
our company needs a script for blocking some ips which connects to the server so heavily
likewise 300 connections from one ip
and we must block them
is there any script which makes this blocking automatically for ipf

freebsd 4.9 is used with plesk

thanks

I dont think there is 'out of the box' solution for ipf/ipfw firewalls.

well since your using freebsd im not really sure of any prebuilt scripts. but you can just use ipchains or iptables to just drop the certain ips

No ipchains/iptables here. There is a nice native freeBSD firewall -> ipfw.

In some cases auto-ban'ing could be done by analyzing logs (syslogd.conf) and writing actions.

If bad ips are accessing apache web server you could try looking for useful modules (something like: http://mion.elka.pw.edu.pl/~lantonia/ )
