An update. This should be used instead: echo 1 > /proc/sys/net/ipv6/conf/DEV/disable_ipv6 echo 0 > /proc/sys/net/ipv6/conf/DEV/disable_ipv6
This seems to work if NM's ipv6 setting is "ignore", but if it is set to "Link-local", then NM appears to somehow block the new address. I glanced briefly at the NM source to make sure Ignore doesn't do anything, but not enough the track down any actual problem. The ip command a few comments earlier appears to sometimes confuse network-manager and cause it to reload the IPv4 connection, too. In my opinion, there should be another option called "Opportunistic", which does what is desired here, and it should be the default. As IPv6 is being newly deployed, it is probably the correct thing to use if it happens to exist on a given network. -- IPv6=automatic breaks IPv4 https://bugs.launchpad.net/bugs/284874 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
