That might be the case in general, but not in the specific case we're discussing. Quoting Dan Geist: > root@cacti:/var/log# cat /proc/sys/net/ipv6/conf/all/disable_ipv6 > 1 > root@cacti:/var/log# ip -6 addr > <null> > Is this intentional behavior, or do I need to dig into the code to > figure out why it's adding v6 sources to the list ***without an active > v6 network stack***? (Emphasis mine.) In summary I think the conditions for AI_ADDRCONFIG actually being useful is met here. While you're right it might not be useful where the interfaces are auto-configured with link-local addresses, I don't think it does any harm there either (it's more like a no-op), so I think it would make sense to add it in any case. (For what it's worth I tried to get improve the usefulness of AI_ADDRCONFIG a long time ago, but that didn't go anywhere: https://sourceware.org/bugzilla/show_bug.cgi?id=12377) Tore _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
