/etc/services is made of people! (and also ports!)

The talk shows that /etc/services stores service names plus authors, email addresses, and dates and that IANA maintains the canonical list; examples include ssh at port 22 (Tatu Ylonen), chipper at 17219 and octopus at 10008. The researcher emails 288 people about entries with about half bounced and gets roughly twenty replies; mac distributions lag by a decade, and more than 400 ports still assigned can be requested from IANA in weeks.
