Overview

topmostp (Topmost Ports) is a tool that allows you to quickly retrieve the most used ports. The source of the ranking is the nmap-services in the nmap repo.

At SecSI we found it useful to get this information to use it in a pipeline of scripts.

Install

You can easily install it by running:

pip install topmostp

A pratical example is the following:

naabu -p $(topmostp top 15 -s) -host secsi.io

In this snippet the output of topmostp is used to retrieve the list of the top 15 ports and it is chained with the naabu port scanning tool.
