In the examples provided, an instance of Metasploitable2 is used to perform this task. For more information on how to set up Metasploitable2, refer to the Installing Metasploitable2 recipe in Chapter 1, Getting Started.

root@KaliLinux:~# nmap -sT 172.16.36.135 -p 80

Starting Nmap 6.25 ( http://nmap.org ) at 2013-12-17 22:03 EST
