In there, "protocol" meaning as in using TCP or UDP with that port. e.g. 631:tcp, 548:tcp, 548:udp Theoretically, I'd expect that I could specify ipp:tcp, and let the system work out what port number to use for IPP services (using /etc/services as its mapping file), and use TCP with it. You'll want to find out whether afp uses TCP or UDP, rather than allow both (unless both protocols are needed). -- Don't send private replies to my address, the mailbox is ignored.
