# /etc/ethers -- the RARP map rarpd answers from, and the ethers(5) database
# glibc's ether_ntohost(3)/ether_hostton(3) read through NSS.
#
# THIS FILE REPLACES UPSTREAM'S, WHICH IS ONE COMMENT LINE AND NOTHING ELSE.
# meta-oe installs `ethers.sample' -- "# see man ethers for syntax" -- as
# /etc/ethers. rarpd loads no database of its own (load_db() is an empty
# function; the README says so), so with an empty map rarp_lookup() finds
# nothing for any client and the daemon answers nobody. On a stock image the
# package is therefore inert, and there is no subject to assert the ethers
# lookup against.
#
# Every address below is from a range reserved for documentation, so nothing
# here can collide with a real host if this image is ever put on a real link:
#   * 00-00-5E-00-53-00 .. 00-00-5E-00-53-FF -- unicast MACs reserved for
#     documentation by RFC 7042 section 2.1.2.
#   * 192.0.2.0/24 -- TEST-NET-1, RFC 5737 section 3.
#
# The two forms in the second field are BOTH exercised, because rarpd treats
# them differently. rarp_lookup() calls ether_ntohost() and then feeds whatever
# it got to gethostbyname(3): a dotted quad comes back from gethostbyname
# unresolved, which is the "Sun mode" the README describes and the only form
# that works on a machine with no name service; a NAME goes through NSS
# `hosts: files dns', and on this image that reaches /etc/hosts and stops,
# because dns has no resolver to talk to.
