The command Nmap is widely used in the video game Hacknet, allowing to probe the network ports of a target system to hack it. In Snowden, Nmap is used in the aptitude test scene about 14 minutes into the movie.
hping is an open-source packet generator and analyzer for the TCP/IP protocol created by Salvatore Sanfilippo (also known as Antirez). It is one of the common tools used for security auditing and testing of firewalls and networks, and was used to exploit the idle scan scanning technique (also invented by the hping author), and now implemented in the Nmap Security Scanner.
ZMap iterates on techniques utilized by its predecessor, Nmap, by altering the scanning method in a few key areas. Nmap sends out individual signals to each IP address and waits for a reply. As replies return, Nmap compiles them into a database to keep track of responses, a process that slows down the scanning process.
This information is very useful to a hacker who is trying to crack a whole system.

If the administrator chooses to link a knock sequence to an activity such as running a shell script, other changes such as implementing additional firewall rules to open ports for specific IP addresses can easily be incorporated into the script. Simultaneous sessions are easily accommodated.
