介绍 :很多人搭建博客或者网站都会被DDOS
攻击,基本都会出现网站打不开,服务器瘫痪,对于我们这些小博客来说,都不会花更多资金买抗DDOS
服务器来防御DDOS
,只能采取些其他办法,DDOS deflate
是一款免费的用来防御和减轻DDOS攻击的脚本。它通过netstat
监测跟踪创建大量网络连接的IP地址,在检测到某个结点超过预设的限制时,该程序会通过APF
或IPTABLES
禁止或阻挡这些IP。
1、安装DDOS deflate
wget http://www.wxiou.cn/usr/down/DDOS/deflate.sh
chmod +x deflate.sh
./deflate.sh
2、配置DDOS deflate
配置/usr/local/ddos/ddos.conf
文件。
##### 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
参数说明:
NO_OF_CONNECTIONS=150
最大连接数,超过会被屏蔽,默认即可APF_BAN
默认是1,建议使用0,标示iptables限制EMAIL_TO=""
填写邮箱账号,到时候有信息会发送到我们邮箱中BAN_PERIOD=600
代表限制该IP 600秒
