lambda, Yes, this has been requested many times. It has not been added as a feature because it's not an easy fit with the current data structures and execution model that Nmap uses. The scan engine uses the a single scan_lists structure to specify what ports to scan for all targets. In order to skip some ports for some hosts, it would require extensive reworking. The most likely way ahead for your request would be integration of the "port scanning from NSE" functionality [1] that has already been submitted [2] and is waiting for full review. With this functionality, we could write a "port scanning" script that would read your input and inform Nmap that the ports in question are open with or without further checking. Then the rest of the scan (version detection, NSE script scanning, etc.) could proceed as usual.

Hello all, during recent scans I often had the problem that I scanned a predefined list of IP addresses from which I already knew which ports are open. I prefer to use the -iL option for large lists of IP addresses but unfortunately it is not possible yet to include ports in input lists. In my use case I would like to create a list like the following: 192.168.0.1:80 192.168.0.1:443 192.168.0.2:21 ... etc. Was this already discussed in the past? Of course I could transform my list into separate commands to invoke nmap with the -p option, but this could be a large overhead. What do you think, would this be a helpful feature for you?
