每一個IP幾個、十幾個或幾十個鏈接數都還算比較正常,若是像上面成百上千確定就不正常了。
wget http://www.inetbase.com/scripts/ddos/install.sh //下載DDoS deflate
chmod 0700 install.sh //添加權限
./install.sh //執行
二、配置DDoS deflate
下面是DDoS deflate的默認配置位於/usr/local/ddos/ddos.conf ,內容以下:
##### 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" //IP地址白名單
CRON="/etc/cron.d/ddos.cron" //定時執行程序
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 //檢查時間間隔,默認1分鐘
##### How many connections define a bad IP? Indicate that below.
NO_OF_CONNECTIONS=150 //最大鏈接數,超過這個數IP就會被屏蔽,通常默認便可
##### 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=1 //使用APF仍是iptables,推薦使用iptables
##### KILL=0 (Bad IPs are'nt banned, good for interactive execution of script)
##### KILL=1 (Recommended setting)
KILL=1 //是否屏蔽IP,默認便可
##### An email is sent to the following address when an IP is banned.
##### Blank would suppress sending of mails
EMAIL_TO="root" //當IP被屏蔽時給指定郵箱發送郵件,推薦使用,換成本身的郵箱便可
##### Number of seconds the banned ip should remain in blacklist.
BAN_PERIOD=600 //禁用IP時間,默認600秒,可根據狀況調整
用戶可根據給默認配置文件加上的註釋提示內容,修改配置文件。
