pfr Ok, so you don't remember what you typed at this screen?
Well, I wrote my.domain 😉
Then, I set hostname=mybox in my rc.conf file.
This means that I shoud have the following /etc/hosts
# $NetBSD: hosts,v 1.9 2013/11/24 07:20:01 dholland Exp $
#
# Host name database.
#
# This file contains addresses and aliases for local hosts whose names
# need to be resolvable during system boot; typically this includes only
# the address and FQDN for this machine's hostname.
#
# By default this file is consulted before DNS, so adding additional
# material here that then becomes out of date can lead to confusion.
# See nsswitch.conf(5).
#
::1 mybox.my.domain mybox
000.0.0.0 mybox.my.domain mybox
#
# RFC 1918 specifies that these networks are "internal":
# 10.0.0.0 - 10.255.255.255 (10/8 prefix)
# 172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
# 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)
Please note that I've hidden the numbers, 000.0.0.0 is actually something else. Don't touch the default.
I hope this helps.
