#11710 closed Bug/Something is broken (fixed)

ipv6 address for does not seem to be working

Reported by: Owned by:

Ross reported being unable to connect to and failed. Running mtr showed that the packets are dropped at

However, using (an alias without an ipv6 address) did work.

So - I've dropped the ipv6 address for until we can fix ipv6 on zimmermann.

dkg - Do you think you could take a look at this and see if you can find a reason? Thanks!

Sorry i missed this when it came in.

it looks like zimmermann wasn't listening on IPv6 at all, and i don't know why.

I looked at /etc/network/interfaces.d/eth0-ipv6 and it said:

iface eth0 inet6 static
  address 2001:470:1:116::6
  prefix 64
  gateway 2001:470:1:116::1

I changed this to the more compact/concise:

iface eth0 inet6 static
  address 2001:470:1:116::6/64
  gateway 2001:470:1:116::1

and then did:

ifdown eth0; ifup eth0

and now it is listening on IPv6 again. I don't know whether the change to the configuration made a difference or not, and i don't know how those files were set up in the first place.

I've re-enabled the AAAA record for, since it seems to be working now.
