How to write an nmap script












0















The network 192.168.3.0/24 has an IDS that is set to trigger after connections are made to 3 or more IP addresses consecutively from a single IP within 500ms or if 3 or more ports are scanned consecutively on a machine from a single IP within 500ms.
Write a script using nmap to look at TCP ports 21, 22, 23, 53, 79, 80 and 123 across the entire network to identify which IP addresses are running any of those services. Ensure that you don’t trigger the IDS of the system. It is OK to use a port scanner other than nmap. You should design the script so that it operates in the most efficient way (i.e. it executes in the shortest amount of time).
