Well 6relayd and odhcpd collect hostnames of clients acquired via
stateful DHCPv6 and export them to dnsmasq in an additional hostfiles.
At least that seemed to work when I last tried it a few months ago. The
only disadvantage is that there is no "ra-names" feature there.
is there a good way for 6relayd and dnsmasq-dhcpv6 to co-exist?
Ideally they could coexist in a way that you could select dnsmasq and /
or odhcpd for different interfaces on the same machine. odhcpd supports
that but dnsmasq the last time I've looked seemed to use a single socket
binding to all interfaces for DHCP/v6 which prevents coexistance from
working correctly because odhcpd / 6relayd can't bind the socket after
dnsmasq did and vice versa.
Feel free to provide me with some debugging information of the system while
PD fails for you so I can have a look at the probable cause:
* "ifstatus ge00" (replace ge00 with your IPv6 upstream interface)
* "ip addr list dev ge01" (replace ge01 with the interface your downstream
router is connected)
* "ps | grep 6relayd"
Anyway I will migrate all the stuff to odhcpd soon (it's successor which
shares a good part of the codebase but is a bit better integrated with the
rest of the environment).
same question re dnsmasq.
Yeah as pointed out coexistence is a matter of binding sockets. odhcpd
will bring the functionality of dynamically enabling / disabling
DHCPv4/v6 on interfaces without restarting the daemon and loosing state.
This is one of the main reasons for the change and very much eases
things for high-level protocols that do dynamic wan/lan detection.

At one level I am happy to figure out this is a recently introduced bug.
On the other hand I am not sure if it is 6relayd.
What version of cero was working for you?
I am not entirely sure, but i think it was from September.

At the moment I lack the ability to debug the breakage in ipv6 dhcp-pd
(which is odhcpd) (I am travelling).
I will on my next stop next week (tuesday) setup a dhcpv6pd server and
see what I can see.

Hi,
I have been using CeroWRT on Comcast with a 3800 for about 6 month.
The
DHCP-PD config has always been a little unstable for me, but working.
I recently upgraded to:
root@cerowrt:/etc/config# uname -a
Linux cerowrt 3.10.24 #1 Tue Dec 24 10:50:15 PST 2013 mips GNU/Linux
My WAN gets a /128, but i cannot get DHCP-PD to work to get addresses
on
the rest of my interfaces. The router does seem to have good IPv6
access.
I fiddled with the 6relayd config and came up with this, but it does
not
work. Any pointers on how to get this back on track? The result of
the
below config is that the /128 from the WAN interfaces is now present on
all
the interfaces but my attached computers get no addresses.
config server 'default'
option rd 'server'
option dhcpv6 'server'
option management_level '1'
list network 'ge01'
list network 'gw00'
list network 'gw01'
list network 'gw10'
list network 'gw11'
list network 'se00'
list network 'sw00'
list network 'sw10'
option fallback_relay 'rd dhcpv6 ndp'
option master 'ge00'
root@cerowrt:/etc/config# uname -a
