To use Scapy to perform a sock stress DoS attack against a target, you will need to have a remote system that is running network services over TCP. In the examples provided, an instance of Metasploitable2 is used to perform this task. For more information on setting up Metasploitable2, refer to the Installing Metasploitable2 recipe in Chapter 1, Getting Started. Additionally, this section will require a script to be written to the filesystem, using a text editor such as Vim or GNU nano. For more information on writing scripts, refer to the Using text editors (Vim and GNU nano) recipe in Chapter 1, Getting Started.
