the output as seen while running Nmap from the command line, but saved to a file. Script kiddie meant to be an amusing way to format the interactive output replacing letters with their visually alike number representations. For example, Interesting ports becomes Int3rest1ng p0rtz. This is known as Leet.
Banner grabbing is a technique used to gain information about a computer system on a network and the services running on its open ports. Administrators can use this to take inventory of the systems and services on their network.

TCP/IP stack fingerprinting. Passive OS Fingerprinting method and diagram. TCP/IP stack fingerprinting is the remote detection of the characteristics of a TCP/IP stack implementation. The combination of parameters may then be used to infer the remote machine's operating system (aka, OS fingerprinting), or incorporated into a device fingerprint.
Performing a port scan and OS identification (-O option in nmap) on the zombie candidate network rather than just a ping scan helps in selecting a good zombie. As long as verbose mode (-v) is enabled, OS detection will usually determine the IP ID sequence generation method and print a line such as “IP ID Sequence Generation: Incremental”.
Classless Inter-Domain Routing (CIDR / ˈsaɪdər, ˈsɪ -/) is a method for allocating IP addresses for IP routing. The Internet Engineering Task Force introduced CIDR in 1993 to replace the previous classful network addressing architecture on the Internet. Its goal was to slow the growth of routing tables on routers across the Internet, and ...
