A bash script to generate comma-separated ranges of top ports for Nmap.
We all know you can use --top-ports 1500 on Nmap...
But what if we want to scan all the top ports from 1501-2000? Or any other range of top ports?
Well this script generates ranges of top ports for you to be able to do that.
This is useful because if you've already scanned --top-ports 1000 and you want to now scan the next 1000 usually you'd have to run --top-ports 2000. BUT this already includes the top 1000 ports you've already scanned so this is a waste of time.
This script saves you time!
Display top ports between specified range:
-r, --range [START]-[END]
Display top [NUMBER] of ports:
-t, --top [NUMBER]
./nmap-top-ports-range-selector -r 10-30
Generates a comma-separated list from the 10-30th most frequent ports:
139,143,53,135,3306,8080,1723,111,995,993,5900,1025,587,8888,199,1720,465,548,113,81,6001
Simply plug this into your nmap command:
nmap <ip> -p 139,143,53,135,3306,8080,1723,111,995,993,5900,1025,587,8888,199,1720,465,548,113,81,6001
Q: Why not just merge TCP and UDP into one script?
A: Because I'm lazy. I'll try to get around to adding a -u flag or something.
