Public bug reported:
Binary package hint: network-manager
Description: Ubuntu 10.04.1 LTS
Network-manager 0.8-0ubuntu3
Everything in ip6tables set to ACCEPT
#ip6tables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Tried it on two different computers with up-to-date Ubuntu 10.04
connected to the same "Freebox" router, one using wifi, the other using
ethernet.
I decided to activate ipv6 in network-manager for my running interface;
I chose automatic mode and the connection to sites like ipv6.google.com
worked fine and ifconfig showed two addresses: a link-local one and an
Internet one:
inet6 addr: abcd:ef12:134:534:8488:1abe:335:2ef/64 Scope:Global
inet6 addr: fe80::8488:1abe:335:2ef/64 Scope:Link
but no address in fec0:: with scope site.
This is rather annoying since it means that to communicate on the local
network, I must use the global address.
The behavior I expected was for network-manager to also configure a site
local address if fec0::
I managed to configure the network manually by modifying
/etc/network/interfaces and now nm-applet doesn't show up but I suppose
this is normal.
I don't know if I shouldn't file a separate bug but here goes:
I also tried manual configuration for ipv6 and added these fields in the
manager:
abcd:ef12:134:534::aaaa / 64
fe80::aaaa / 64
fec0::aaaa / 64
but with that, the site-local (fec0::aaaa) address works but not the global one.
When I do "ping6 ipv6.google.com", I get "connect: Network is unreachable"
