Since yesterday I have a new arrangemet wrt my IPv6 connection, and I'm
trying to use dhcpcd to manage the addresses tat are assigned to me from
my provider (xs4all.nl). They do native IPv6 via Fritz!Box modems and
(V)VDSL.
Little schematic:
.--------. .-----------. .------.
| xs4all +------+ Fritz!Box +-----re1+ Main +re0---- local network
`--------' `-----------' `------'
So I thought I'd use the example give in the manual page,
dhcpcd.conf(5):
noipv6rs # disable routing solicitation
denyinterfaces eth2 # Don't touch eth2 at all
interface eth0
ipv6rs # enable routing solicitation get the
# default IPv6 route
ia_na 1 # request an IPv6 address
ia_pd 2 eth1/0 # get a /64 and assign it to eth1
This didn't work at all! And when it did things, it did them wrong.
(Of course I adjusted for my interfaces).
It took me a while to realise that this is a devilishly deceptive
example. dhcpcd does not allow end-of-line comments!
That surely should be made clearer in the manual, closer to the example,
and not just the line near the start "Blank lines and lines starting
with # are ignored.".
Now that I've come past this hurdle, after some time (about 40 minutes),
I get syslog messages like in the subject:
Feb 4 20:51:48 murthe dhcpcd[10390]: re1: DHCPv6 REPLY: iana not found
Around the same time, ifconfig shows my IPv6 address has gone
deprecated.
Any idea what's wrong?
This is what gets logged when I restart dhcpcd manually,
and it includes another one of those "iana not found" messages:
