When the IP Address is banned, we have to define the ban time also. In the above figure, I have put numbers to indicate each configuration for better understanding of the users. In order to do this, we have to open the nf file in the VI editor as mentioned below. This command counts the total number of connections for every IP address connected to the server.Īfter installation of the DDOS Deflate tool, we have to configure it. We can say that this command is the heart of the DOS Deflate tool. Netstat -ntu | grep ‘:’ | awk ‘’ | cut -f1 -d ‘:’ | sort | uniq -c | sort -nr > $BAD_IP_LIST To do this, we need to open the ddos file with an editor and comment the line 118 by adding the ‘#’ before the line and write the following command: This file will also check all IP connections on the server.įirst of all, we will change some commands in the main ddos.sh file to make the tool more effective. But this configuration can be changed from the nf file. The second file is ddos.sh, which is basically the main script file for the tool, and third is the ignore.ip.list file, which is the IP white listed file in which we can define the IP addresses which need to be excluded through this tool.Īlong with the install, a Cron file is automatically created in the /etc/cron.daily folder that will run every minute, as the default configuration is 1 min. conf file in which all tool configurations will be set as per the requirement. We can check the DOS Deflate files in /var/local/ddos/. Now, DOS Deflate has been successfully installed in the system.

It will install DOS Deflate in the system. Now, after getting the executable permission, we have to run the install.sh file. This can be done through the following command. The downloaded filescan be checked through the ls-l command.Īs can be seen, the downloaded file does not have executable permission. Now, the Installer script file “Install.sh” has been successfully downloaded. Open the terminal and then type the following command.

Here are all the steps we need to follow to install and configure DOS Deflate on the machine.įirst of all,we have to download the installer script file, which is available on the DOS Deflate website through the wgetutility. Whenever it detects the number of connections from a single node exceeding certain pretest limits which are defined in the configuration file, the script will automatically block that IP address through the IP tables or APF according to the configuration. It basically tracks and monitors all the IP addresses making connections to the server by using the netstat command. Though it does not protect us fully against large DDOS attacks, it is very helpful.ĭOS deflate is a lightweight bash shell script designed to assist in the process of blocking a denial of service attack. So, in this article I am going to introduce a little script based tool “DOS Deflate” which helps to fight against Application Layer DOS.
