If you don't have DNS configured, or you do not have reverse DNS entries
for the host IPs you are talking to, then only the IP will be listed above.
So far I only have a rudimentary IPv6
configuration on FreeBSD 7 running and it only sees the IP address, and
then only after I ping the other end.
What you see above is normal functionality of the IPv6 Neighbor
Discovery Protocol (RFC-4861). The 'neighbor cache' only gets populated
with entries when IP communication takes place, or you receive/accept a
router advertisement with a list of prefixes (ndp -p).
The fact that names are not appearing is due to (mis|non) configuration
of DNS either for the resolver on the box itself, or reverse DNS missing
for the LAN IPs as stated above.
To add a DNS server in FreeBSD, simply:
# echo "nameserver ip.of.name.server" >> /etc/resolv.conf
I couldn't find anything in
/etc/defaults that seems to address auto discovery. Is this something I
have missed or what?
Perhaps you are referring to 'Auto Configuration' (RFC-4862)? Neighbor
Discovery and Auto Configuration perform different tasks, but the former
is required by the latter.
Can you describe exactly what you want to achieve? Is it only the name
resolution problem you described above?
