Здравствуйте. Я понимаю что телепатов нет тут но все таки хочу попробовать спросить почему когда я использую этот скрипт то он работает хорошо только когда я захожу на сайте на любую страницу с Rewrite, привязанному к самому движку сайта. А вот когда создаю папку (arro) с корне для другого приложения то скрипт выдает что как будто был заход с 127.0.0.1
что не позволяет мне блокировать автоматом адреса реальник пользователей(что этот скрипт и делает). В Папке буду лежать другие папки с разными файлами. Подскажите как заставить вестись правильно статистику ? Спасибо заранее#!/bin/bash

##### Caution: Every time this setting is changed, run the script with --cron
##### option so that the new frequency takes effect

##### How many connections define a bad IP? Indicate that below.
NO_OF_CONNECTIONS=100000
##### APF_BAN=1 (Make sure your APF version is atleast 0.96)
##### APF_BAN=0 (Uses iptables for banning ips instead of APF)
APF_BAN=0
##### KILL=0 (Bad IPs are'nt banned, good for interactive execution of script)
##### KILL=1 (Recommended setting)
KILL=1
##### An email is sent to the following address when an IP is banned.
##### Blank would suppress sending of mails
