Preventing DoS attacker for my server ?

Hello Ruth, I have read your concern regarding how to prevent DoS or DDos attacks on web servers. Intruders and attackers are really troublemakers for us who are into having our own websites, personal or business type.  I have learned recently on how to protect a server and prevent it from DoS attack. One good tool, and actually cost saver, would be the use of software-based firewall named “DoS-Deflate”. DoS Deflate is a script which is designed to assist block and prevent service attacks. It can detect and track IP addresses that are being established on large numbers of connections. When large amount of connections are detected from a single node that exceeds its limit, the script will automatically uses APF (Advanced Policy Firewall) or IPTABLES to ban and block the IP addresses.

Installing Dos Deflate is easy. Here are the steps:

1.     Log in to your server as root

2.     Download the script wget http://www.inetbase.com/scripts/ddos/install.sh

3.     Run the installer (sh install.sh)

The configuration file is “ddos.conf” . If you wish to change the default settings, you can do so. And if you want to permanently block some IP addresses, just list them in /usr/local/ddos/ignore.ip.listfile. I hope this helps. 🙂
