a.k.a. what I wish were there when I was writing my first penetration testing reports. No subpages, no ads, no shitty paragraphs pretending they contain a lot of useful information. Just one page and CTRL+F!
This is a list-in-progress of the usual usage of TCP/UDP ports and their description. Note that it doesn't have to necessarily apply to your system. The purpose is to gather knowledge about less-known ports, so if you happen to know more about ports that lack of description, please let me know (or feel free to contribute).
