Do you want to attack a server or a client by DoS Attacking?
From Wikipedia:
A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of a person or persons to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely. Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers.
So there are lots of tools and scripts for DoS Attacking. (Google it: “DDoS tools” or “Denial of service tools”)
One of the simplest and most usable tool is Hping.
From Hping.Org:
Hping is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired to the ping(8) unix command, but hping isn’t only able to send ICMP echo requests. It supports TCP, UDP, ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many other features.
You can download it from here. Hping is available for Unix Based and Win32 Systems.
If you are in K/Ubuntu Linux, just type “sudo apt-get install hping3″. If not in K/Ubuntu, check your Package Manager and search “hping” to find.
After installation, go to your terminal and type “hping3″ for help. Or type “man hping3″ for manual page for hping.
For Windows users, open CMD (Win + R, then type “cmd”) and go to the hping directory and type “hping.exe –help”.
***Note: Before you starting to use hping, disable your Firewall.
So… One of the best commands is:
hping3 –flood -a [Faked IP] -e “Message” -S -s [Source Port] [Source IP]
You can find out the parameters in the help section of hping.
So start the attack and see the results.
