Linux(Centos如何防DDOS进攻软件DDoS呢？

  DoS-Deflate是一款免费的用来防备和减轻DDoS进攻。它通过netstat监测跟踪创建大量收集毗连的IP地址，在检测到某个结点超越预设的限造时，该法式会通过APF或IPTABLES制止或阻挠那些IP。

DDoS-Deflate安拆及设置装备摆设

1、安拆

wget 。

  inetbase。com/scripts/ddos/install。sh

chmod 0700 install。sh

。/install。sh

2、设置装备摆设

设置装备摆设文件是 /usr/local/ddos/ddos。conf ，默认有如下设置装备摆设

FREQ=1

NO_OF_CONNECTIONS=150

APF_BAN=1

KILL=1

EMAIL_TO=”root”

BAN_PERIOD=600

IP地址白名单：/usr/local/ddos/ignore。

  ip。list

卸载

wget

chmod 0700 uninstall。ddos

。/uninstall。ddos

MediaLayer was in need of a script to automatically mitigate (D)DoS attacks。

   The necessity started when MediaLayer was the target of a rather large, consistent attack originating from multiple IP addresses。

   Each IP would have a large amount of connections to the server, as shown as by:

netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n。
