怎么简单免费抵御DDOS攻击?使用DDOS deflate 我们在使用的VPS主机中,因为是按照流量消费的,在耗尽我们的流量,遭遇大量的DDOS攻击之后,也束手无策,那么怎么简单免费抵御DDOS攻击? 在遇到这些问题的时候,我们是否能在VPS设置中进行处理呢?哪怕是一点点的防御。看到DDOS deflate脚本是可以协助VPS阻止攻击进程的,如果遇到来自某个IP的持续攻击,可以给该IP自动的设置成IP黑名单。只能说可以给我们的VPS一点点防御。 怎么简单免费抵御DDOS攻击?使用DDOS deflate 第一步,安装。 wget http://myvps-scripts.googlecode.com/files/deflate.sh chmod +x deflate.sh ./deflate.sh 第二步,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 标示说明: 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 (责任编辑:IT) |
