Okay, now I've tested a bit with the Oneiric Alpha 3 live image. Highlights:
- The default Wired connection profile now has set the IPv6 mode to Automatic by default. - ...however, it behaves as if it is still set to «Disable» and does no attempt of configuring IPv6. - DHCPv6 appears broken, any activation attempt fails with a dhcp-error - Also, dhclient6 appears to corrupt its own lease file. Test #1: Wired ethernet, dual-stack network ------------------------------------------- * Connection profile «Wired connection 1» has by default IPv6 mode «Automatic». * However, DHCPv6 is not attempted. Behaves as if IPv6 mode is «Disabled». * «Require IPv4 for this connection to complete» is set. * IPv4 DHCP activation succeeds, as do the overall network connectivity. Test #2: Wired ethernet, single-stack IPv6 network -------------------------------------------------- * Like test #1 - IPv6 configuration not performed in spite of IPv6 mode being set to «Automatic». * See attachment test2.oneiric-a3.wired.singlestack.syslog * Since IPv4 is required and not present, the overall connection fails (as expected I guess). Test #3: Wireless ethernet, dual-stack network ---------------------------------------------- * Same default settings as for the Wired ethernet profiles * DHCPv6 is attempted, but fails with «DHCPv6 client didn't bind to a lease». * Connection attempts loops and fails for 13 iterations until it settles with only IPv4, no IPv6 configuration active. * See attachment test3.oneiric-a3.wireless.dualstack.syslog Test #4: Wireless ethernet, single-stack IPv6 network ----------------------------------------------------- * Same default settings as for the Wired ethernet profiles * DHCPv6 is attempted, but fails with «DHCPv6 client didn't bind to a lease», as in test #3. * Eventually corrupts the dhclient6-*.wlan0.lease file: Aug 6 13:01:01 ubuntu dhclient: /var/lib/dhcp/dhclient6-186b9d3d-e0d2-4fdc-a8a4-54798bef6345-wlan0.lease line 4: expecting hexadecimal number. Aug 6 13:01:01 ubuntu dhclient: ia-na "jPb`" * Connection attempts loops and fails for 4 iterations until it gives up completely, leaving the network disconnected. * See attachment test4.oneiric-a3.wireless.singlestack.syslog -- Tore Anderson -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/761558 Title: Default to enabling IPv6 addresses, but set to optional to bring up devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/761558/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
