!!Con West 2019 - Breanne Boland: /etc/services is made of people! (and also ports!)

Presented at !!Con West 2019: http://bangbangcon.com/west Every computer, Windows, Mac, and *nix alike, includes some variation of the /etc/services file, the rare file that is both machine-usable and human-readable, so that applications and people alike can know what ports are meant to be used for what purposes. But the further you go into this 13,000-line file, the more traces of humanity you see — names, email addresses, and dates paired with information about ports and the apps that claim them. Who are these folks? How did their names get in the file that came with your OS? Why does “chipper” get port 17219 and “octopus“ claim port 10008? Who oversees this vital file that puts the “ssh” with port 22 when you netstat? And how could you get your own piece of port-assignment glory?
