Hi Simon,
do you have any recommendation for me, which one I can test?


I've not tried the server, but the Dibbler client and relay have
behaved well in my testing and are easy to configure and well
documented. ISC have a dhcpv6 server too.

Hi Simon,
i've installed now dibbler and tried so get an ipv6 with Win7. It fails.
Win7 timeouts the same way as with dnsmasq.
Maybe you see, why its failing:

The only error I see, is: Unable to find suitable vendor-specific info
option.
The Log @00:27:15 repeats every few seconds.

Hello Simon,
so do I need to use radvd simultaneously with dnsmasq, in order to get
stateful dhcpv6?
I've now enabled it and some sort of success. Both options
(AdvManagedFlag, AdvOtherConfigFlag) are enabled.
My Win7 gets an IPv6-Address and a DNS-Server for ipv6, but not an
gateway. I guess, I need a correct option6 for gateway, but I don't know
how to name it. Where can I find those option names, as I was using
numbers for ipv4 (like 3 for gateway, or 40 for dns-domain-name).

So far, i've only set:
dhcp-option=option6:dns-server,[2a01:AAA:BBB:0::1],[2001:4860:4860::]
dhcp-option=option6:ntp-server,[2a01:AAA:BBB:0::1]

I've also some troubles with setting static dhcpv6. For my
understanding, I've so set set instead the mac address and duid, but it
seems ignores for me with this line:
dhcp-host=00:01:00:01:15:E9:74:8C:XX:XX:XX:XX:XX:XX,2a01:AAA:BBB:0::2,Valkyrie

Thanks!
Conrad

Yes, it seems you do.

My understanding is that the gateway comes from the router
advertisements, so it's a radvd thing. There is no DHCPv6 option for
default gateway.

I'm seriously considering adding RA functionality to dnsmasq: just
enough to allow DHCP to work. That should make this sort of thing easier.

You can get a list of all the DHCPv4 options that dnsmasq knows about with

dnsmasq -w dhcp

and the same for DHCPv6 options with

dnsmasq -w dhcp6

The numbers are not the same for DHCPv4 and DHCPv6

You are giving a (very long) MAC address there, to set the DUID, you
need to precede it with "id:", so this should be

dhcp-host=id:00:01:00:01:15:E9:74:8C:XX:XX:XX:XX:XX:XX,2a01:AAA:BBB:0::2,Valkyrie

[Dnsmasq-discuss] no address range available for DHCPv6

[e9hack]

Hi,

I'm trying to check the DHCP6 capability on my ADSL router. I add the following 
options to
the dnsmasq.conf file:
dhcp-range=fec0:0:0:::100,fec0:0:0:::,48h

I get an error message in the log file of the router:
daemon.warn dnsmasq-dhcp[2449]: no address range available for DHCPv6 request 
via br0

It seems that dnsmasq accepts the IPv6 address range:
daemon.info dnsmasq-dhcp[2449]: DHCP, IP range fec0:0:0:::100 -- 
fec0:0:0:::,
lease time 2d

DHCP works in parallel without any problem.

Regards,
Hartmut
