SSH执行以上命令,若提示“iptables: Firewall is not running.”表示iptables未运行,需要执行“service iptables start”运行iptables。详情可参考:《》。
二、安装DDoS Deflate
1、下载 ddos.rar
wget http://soft.kwx.gd/security/ddos-Deflat.sh
2、设置权限并运行脚本
chmod +x ddos-Deflat.sh #设置为755权限
./ddos-Deflat.sh
这时脚本会自动下载并安装。若提示类似于“免责声明”等英文字样,按“q”键或任意键即可退出。
三、设置DDoS Deflate
1、修改指定文件
vi /usr/local/ddos/ddos.conf
2、根据以下相关说明设置
##### 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白名单文件
CRON="/etc/cron.d/ddos.cron" //定时执行
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 //检查网络时间间隔,单位为分钟
##### How many connections define a bad IP? Indicate that below.
NO_OF_CONNECTIONS=150 //单个IP最大连接数,若超过则执行规则,默认即可
##### 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还是iptables。推荐使用iptables,将APF_BAN的值改为0即可。
##### KILL=0 (Bad IPs are'nt banned, good for interactive execution
of script)
##### KILL=1 (Recommended setting)
KILL=1 //是否屏蔽IP,默认即可
##### An email is sent to the following address when an IP is banned.
##### Blank would suppress sending of mails
EMAIL_TO="root" //当IP被屏蔽时给指定邮箱发送邮件,若不使用则在前面加“#”屏蔽
##### Number of seconds the banned ip should remain in blacklist.
BAN_PERIOD=600 //禁用IP时间,默认600秒
3、保存文件即可生效
