快速过滤出IP添加到IPtables中
1、第一版：
# awk '{IP[$1]++}END{for( i in IP ) print IP[i],i}' \
logs/localhost_access_log.2016-12-10.txt |sort -nr | \
head -n 130|awk '{print $2}' >111.txt
# awk '$1>=100{print $0}' 111.txt
# for i in `cat 111`;do iptables -I INPUT -s $i -j REJECT ;done
2、第二版
#!/bin/bash
File=$1
ExcludeIp="2.2.2.2|1.1.1.1"
awk '{IP[$1]++}END{for( i in IP ) print IP[i],i}' $File | sort -nr |egrep -v "$ExcludeIp" > temp.ip
awk '$1>=10{print $0}' temp.ip > temp.ip.1
for i in `awk '{print $2}' temp.ip.1`
do iptables -I INPUT -s $i -j REJECT
done
