I'm trying to run an UML in IPv6 mode on a Linux (Ubuntu) box, and have not been successful with it. I could get the UML to boot up alright, but the interfaces do not seem to accept IPv6 addresses. The file /etc/config/network looks like this: config interface lan option ifname 'eth1' option proto 'static' option ip6addr '2001:220:abcd:70::10/64' Adding it manually doesn’t seem to help either: root@OpenWrt:/# ifconfig eth1 add 2001:220:abcd:70::10/64 ifconfig: socket(AF_INET6,2,0): Address family not supported by protocol root@OpenWrt:/# ip -f inet6 addr add dev eth1 2001:220:abcd:70::10/64 RTNETLINK answers: Operation not supported root@OpenWrt:/# ip -f inet6 addr add dev eth1 2001:220:abcd:70::10 RTNETLINK answers: Operation not supported root@OpenWrt:/# ip addr add dev eth1 2001:220:abcd:70::10/64 RTNETLINK answers: Operation not supported I referenced a few OpenWRT links that talk about how to enable IPv6 on the system, and believe I have it in place.

Since you seem to have IPv6 module loaded, and IPv6 addresses in your
ifconfig output, but your ifconfig won't add it.
If your 'ifconfig' from busybox? Maybe it is too limited to do the work.
You mention WRT, which is why I suspect ifconfig is really at fault.
But, your ifconfig line seems wrong to me:
ifconfig eth1 inet6 2001:220:abcd:70::10/64 up
would seem to be the right incantation.
I usually do:
ip -6 add addr 2001:220:abcd:70::10/64 dev eth1

You're right about 'ifconfig' belonging to busybox. But things work fine for IPv4 with exactly the same procedure. Also, in IPv6, eth1 comes up with link-local address; it just doesn't get assigned the specified address. Assigning the v6 address from the command-line works fine though. ________________________________ From: Michael Richardson <mc...@sa...> To: madhusudan r <mad...@ya...> Cc: "use...@li..." <use...@li...> Sent: Monday, 24 June 2013 8:17 PM Subject: Re: [uml-user] Configure UML to work in IPv6 mode Since you seem to have IPv6 module loaded, and IPv6 addresses in your ifconfig output, but your ifconfig won't add it.

Right... so busybox ifconfig doesn't speak enough IPv6, perhaps.

Please say this more clearly.
You said that ifconfig failed.
Are you now saying that ifconfig works?
Or did you do ip?

I tried this with an image from a fresh build and the interfaces come up alright. Thanks for your answers/comments. ________________________________ From: Michael Richardson <mc...@sa...> To: madhusudan r <mad...@ya...> Cc: "use...@li..." <use...@li...> Sent: Tuesday, 25 June 2013 11:35 PM Subject: Re: [uml-user] Configure UML to work in IPv6 mode madhusudan r <mad...@ya...> wrote: > You're right about 'ifconfig' belonging to busybox.
