昨天老高的博客受攻击了，本想着没啥流量就不用太在意，哎，防人之心不可无啊！

先装个DoS-Deflate试试看效果吧！

下载

wget http://www.inetbase.com/scripts/ddos/install.sh
sh install.sh

配置

vi /usr/local/ddos/ddos.conf
# show
##### Paths of the script and other files
PROGDIR="/usr/local/ddos"
PROG="/usr/local/ddos/ddos.sh"
IGNORE_IP_LIST="/usr/local/ddos/ignore.ip.list"
CRON="/etc/cron.d/ddos.cron"
APF="/etc/apf/apf"
IPT="/sbin/iptables"

##### frequency in minutes for running the script
##### Caution: Every time this setting is changed, run the script with --cron
#####          option so that the new frequency takes effect
FREQ=1

##### How many connections define a bad IP? Indicate that below.
NO_OF_CONNECTIONS=150

##### 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
EMAIL_TO="root"

##### Number of seconds the banned ip should remain in blacklist.
BAN_PERIOD=600

使用

白名单路径：/usr/local/ddos/ignore.ip.list 配置文件路径：/usr/local/ddos/ddos.conf

卸载

wget http://www.inetbase.com/scripts/ddos/uninstall.ddos
sh ./uninstall.ddos
